With hydro clutch becareful no to over extend the clutch, a stop may be needed. Does the clutch work ok when stopped to put in 1st? Could be type of oil? Bent shift forks? How about a shift at speed without using the clutch?

I use the bike's factory master cylinder
When i am at idle with neutral and i want to engage 1st or 2nd gear, it's like the clutch is not fully engaged and a terrible sound i herd from the gearbox
At high revs i can upshift without clutch, but it takes some practice

Today i have worked almos 10 hours to get my trailer done!
My uncle had a water tank trailer that he did not want it, and with some extensions i managed to make it wide and long enough to fit my buggy in :D
Tomorrow i will make 2 ramps and finish adding the 2mm steel sheets

Some updates!! I have decided to do a total front suspension reconstruction because i don't like it..
A relative who drove the buggy told be the same thing, that the front suspension is not working properly

So since i have the St4 construction drawings i have decided to build the front suspension of it, but firstly modify it to suit my shorter shocks!

Also i will be modifying slightly the rear, based again on the rear suspension of the St4.

The main problem is with the bushes and the pivot axles.. Now each arm will have 4 bushes with crush sleeves and 2 bolts. I am looking for car suspension bushes this time to suit my application

Dang! I guess if you don't like it then you need to change it. Lots of bushings out there in stiff plastics. You just have to pay the VAT and shipping.

Or just order a polyurethane rod and make some bushings in your lathe.

But can't you change the design to fit 1 axle instead of 2? Just let the bar run through?

I am very confused right now.. I don't really know what to do
All bushes now are made of teflon. I may widen the id of the bush so i can add a long sleeve and then run a single bolt through the sleeve.. My uncle said that the main problem is that there is no metal sleeve between the bush and the rod

gvouvakos
08-12-2013, 04:17 PM
Did a research again and i have realised that it is not necessary to have 2 bolts for each a-arm
Tomorrow i will go search in the shop for a tube that will fit a 1/2" bolt from the inside and then drill my bushes with the same dimension of the OD of the tube.. It will be used as a crush sleeve!
This should do.. Any opinions?

So I would say this. Make wheel stops on the front of the trailer so you won't drive off the front of the trailer.
I would even try to make side rails for the same reason.

Looks good. I have to work onto trailer too. This is motivation.

I second chikin's statement, I would say your main worry is your hard drive transfer rate, if it's low you'll wait hours to transfer a 15 minute video in HD....

Need some help now.. I have those stupid tractor pto axles and they constantly break. I am thinking of replacing them with cv joints.. I cannot afford 930, so i was thinking of using car cv axles.

Any suggestions?? have in mind that one end must have a flange and the other to be a spline shaft with the hub.. ;)

Eventually i went to the trip, the weather did me a favor :D

Everything work perfectly, except only once, when the rod that connects the rear brake master cylinder with the balance bar unbolted, but it was quick fix, i will loctite it tomorrow!

Also i 've made a new speed record.. 115 km/h (72 mph) with fifth gear with the engine revolving just before it reached redline. I was afraid to push it even more, and add 6th gear.. It will reach 130-135 kmh for sure!!!

Looks great. I don't think you have much if any axle plunge, JGSturbo is using outer cv's from f150 for outer, inner and outer stub. They have no plunge. They fit 28 spline axles which are very common,same as 930 cv. I'm using f150 outer/stub, 28 spline axle and 930 inner. F150 inner has a flange mount, might be easy to adapt.

Anw decided to add reverse.. electric reverse to be exact

I was thinking of adding the flywheal onto the center spool but i don;t have space to fit that thing in there,, it will hit the engine. So i had the idea to run a chain from my center spool to a new short jackshaft that will be held in place by 2 pillow blocks.. there will be a 2 to 1 reduction to give more torque.. the flywheel willl be placed on the jack shaft.. i have made a simple drawing for you to understand!

i am looking for a diesel starter of a 2 or 2.5 litre car, with the ring gear, i will laser cut a round flange and weld the ring gear on it

but i am really worried if this will add a lot of friction to my system.. another jack shaft will be added, with 2 more bearings, a huge ring gear plate etc etc

what do you thing?

(the box with the electronics will be moved to make space for the jackshaft)

I don't know if friction is the right word, but yes it will certainly add a lot of drag to your drivetrain system. Getting a big flywheel up and spinning will rob some power from your engine. Maybe you could use a dog gear and only engage the flywheel when you need reverse.

i was thinking of using a one way bearing pressfitted on one of the sprocket, bu those things are very expensive, i ve got a quote for 120 euros for one bearing

If you could come up with the room between the pillow blocks on your carrier, ATV centrifugal clutches/primary drive gears have a one-way bearing in them. Possible low cost one-piece source. Cut the clutchbell off, mount the "remains" on the shaft and put one of the donor's secondary gears on the starter mounted above the carrier.

You need to spin those clutches pretty fast before they engage. Not sure if a starter could get it up to speed to engage it.

So 115 km/h!!!! That's nuts! Mine tops out at 80 and that feels pretty fast to me.

if the u-joints have a grease fitting, make sure you mount them in compression, otherwise the fitting bore is a good place for a crack to start.

Hey guys it's being a lot of time since my last update on the buggy!

I have been driving it for 3-4 months with no problems! i ended up buying a new u joint axle italian made.

Today i managed to crack a tube during a jump, hopefully the tube hold on till i get home. I will fix it and reinforce the front end tomorrow or the day after

NOT GOOD!!!

Take another piece of tubing, split it long ways and then cap the broken area (after you weld it). Is there room to put a vertical piece of tubing between the lower and upper front a-arm mounts? It would be right there where you broke down to the tube below. That on both sides would probably help tremendously.

Duane
01-19-2014, 11:48 AM
That crack looks like it has been working for awhile before it let go. It most likely started under the tube and worked its way from there. I think K-fab has a good solution.

01-19-2014, 01:54 PM
Kfab thats exactly what i had in mind! but i will also add horizontal reinforcement between the 2 upper arms mount tubes

Good plan on the extra tie in across the top. I wasn't sure if there was room or not - I guess your pedals are no where near that far forward.

Re welded the tubing and added a horizontal bracing, some paint and it should be ready to go! In the picture it looks like the steering column hits the tube but there is 1 cm of clearance!
I may add some vertical support between upper and lower tube

did you just weld the crack on the tube???? you need to grind the weld smooth and sleeve the tube and weld that get a piece of tube with ID the same as the OD of the chasis tube slice it lenght wise and drill some holes on both halves and weld it to the chasis in the holes and along the butt where the tow halves join together make it alot stronger or you will break again!!!!

Hey guys.
When i hit the brakes hard the whole buggy goes for a nose dive. does it mean that i dont have sufficient braking in the rear? i have a pair of car disc brakes in the front.. but in the rear i have only a single rotor with a motorcycle caliper! i was thinking of also adding outboard brakes in the rear like in the front! but will it worth the extra weight and money?

K-fab

The car's gonna nose dive if you have a lot of travel.

Can you lock up all four wheels or just the fronts?

The fronts can do upwards of 80% of your braking, but if the rear's not up to task, you may need more.

Can you do any brake balancing? Single pedal running two master cylinders with a balance bar between them. The bar can be adjusted to vary the amount of braking front to rear.

thanks for the help, i will adjust the balance bar and see whats gonna happen

I never can remember which way to move the little uni-ball in the balance bar to increase one or the other master cylinder. Centered between the pedals is equal but if you move the little uniball towards the left master cylinder I don't know if this increases or decreases that one's effectiveness. Let us know how it works.

just ordered a brand new gopro silver edition plus!

I was going to buy the roll bar mount but it says its for tube diameter 35 mm to 63.5mm

Should i get this mount and use high density rubber 2-3mm thick to increase the diameter of the tubing? wrap it around

Hey guys!
Finally i have a few days to spend on the buggy, i will be rebuilding the front end and steering system because its not working well. I will incorporate the front suspension from the st4, which includes new suspension mounts, a arms, modified uprights, new shock mounts, new tie rods and steering column.

Today i picked up the laser cut steel plates from the shop! i love receiving freshly cut parts :)
Ordered some new ultra high performance kevlar lined rod ends!

I have a wuestion, my previous sprocket teeth where bended, is there a way to harden the teeth of the new sprocket? the 2 small ones are for a idler sprocket

The sprockets are 530 pitch, which is the one most people use hear

I get that the pitch is right but i am talking about the actual tooth profile / shape.

Not saying it would not be ok but it is not optimal , i wondered if the profile you used or the laser cutter used is just a generic shape. Kinda looks a bit industrial .

High horsepower, high speed motorcycle tooth profiles are a certain shape for a reason.

I cant seem to find a good pic to link to show what i mean , just google it .

K-fab
05-21-2014, 10:16 PM
The tooth profile on "performance" sprockets is actually a really intricate mathematical formula. The industrial stuff is very basic and when used at higher speeds, tends to wear both chain and tooth pretty quickly.

Looks like there's not much heat treating on that sprocket. Pretty classic soft teeth profile.

TALON
05-23-2014, 01:00 AM
Also looks like they were originally some where near the profile of an off the shelf proper bike sprocket , ie nothing like the one at the top of the page.

I am assuming the one you have cut is a low carbon or mild steel so i dont think you can get a lot out of trying to make it harder.

Next time try and get some really tuff material [ no idea what is available in Cyprus ]and cut them from that , or something you may be able to flame harden yourself .

gvouvakos
05-23-2014, 10:46 AM
Yes its mild steal. The company with the laser cutter did not have stronger steel.
Do you think stainless steel would be more suitable?

Why did you use pipe at the end? Why not massive tube adapters with the rod end threat already turned in? It's way stronger! The massive load and jump/bump blows now rests on the thin wall of the tube you welded in.


And did you already bought the GoPro chassis mount? I have the bigger one and it works great! Also on smaller diameter tubes then 35mm.

Good luck! Your front end looks killer!

Hello guys!

Time to spend some time on the buggy! I have decided to move the engine forwards to clear the chain so that no idler will be used. I will replace the motorcycle discbrake and caliper that i have in the rear with a larger discbrake and a 4 piston caliper. Bought new sprockets made of high carbon steel with the teeth heat treated, i will machine the bore and they will be ready to go. I will buy tomorrow a new o-ring chain, new pillow blocks for the mid jack shaft. More to follow

Hey guys!

Its being a lot of time since my last post so i have decided to update the thread!

The modifications to the chain and sprockets made significance difference to the driving of the buggy. No noise or friction from the idler since i removed it!

The rear disc brake with the big caliber i have added in the rear have increased significantly the braking power of the buggy. I can now lock all 4 wheels on tarmac, and the buggy turns better on corners since i have more braking power in the rear. I have now replaced both u-joint axles with some higher quality ones they work better.

Not much driving in the last months but i have a new video!

Okay sweet. I'm thinking of starting a build with double a arm rear suspension and I would like to use pto shafts because they are cheaper for me to get than cv joints/shafts. Will the ptos with universal joints be able to handle a 600-1000 cc street bike engine? Also, will they need to be telescopic or is there a way to make the geometry of the suspensions so I can use solid axles?

Hey guys!

Its been a long time since my last post!

I have decided to update some parts of the buggy!
the engine will be taken for a carburetor rebuild.. since it doesn't work that good for the last 2-3 months.
I have removed the small bike radiator and will be replaced by a bigger aluminum radiator since summer is coming.
Also i will be replacing the fuel tank with a custom one that i have started fabricating!
Ordered new rubber seals for the clutch slave cylinder and master cylinder.
All fuel and water hoses will be replaced with higher quality ones.
Stay tuned for more pictures and updates

Hello everyone.. its been 2 years since the last time i posted on here! i had to take the engine out of the buggy in order to do a recondition of the whole buggy and engine! decided to strip it down, clean everything and repaint with new colours ( most probably a black/ silver combination with metallic red suspension arms ) . The engine in up and running hopefully good enough! I am currently looking to buy four new rims to make it look even nicer! will keep you posted

Hi Giorgos,

Nice to see you back on the site. I think you have a lot of fun the last years with your buggy.
Are you going to refurbish it or are you going to do some changes as well?

Your chain is quite rusty... you need to regular maintenance on it to keep it good.

Can't wait to see your updates here.

I am currently doing a full recondition to get everything perfectly running, and looking nice! I did manage to get the frame ready for paint, 1 coat of red oxide primer plus 2 coats of industrial black paint! I am very pleased with the result but i will probably use a glossy lacquer coat to protect the paint plus add some more gloss to the frame!

Decided to reconstruct the rear suspension arms as i realised they are quite bent. Still not sure what to do but most probably i will use the ST4 rear suspension design as what i did for the front as well a few years back!

Hello everyone,

Did manage to do some work during the weekend! started assembling the front end, tomorrow i will work on the steering column and pedals!

I still need to reconstruct the rear suspension arms but i decided to finish the front and then move to the back.

I have made a small timelapse video that i have recorded using my gopro during the paint job!

Hope you enjoy it

Bought a set of new wheels! managed to get the engine running perfectly! I fabricated some new arms for the rear suspension as they were quite bent! it should be up and running in 3-4 days
