    Hi Stress. Seen these items a while ago and thought they might be useful, maybe this could help deal with the brake issue.

    First Pix is a remote mount brake booster to use in conjunction with your existing master cylinder.



    Second Pix is an electric brake vacuum pump to use with the remote brake booster, should increase braking power.

    Thanks Ironknot

    I did not like the load paths on the Yamaha roll cage. I have a standup wheelchair, so I was able to work on the roof of the roll cage. So I modified the roll cage. I removed the roll cage cross bars on the roof then I cut the brackets off the main roll cage bars on the side of buggy.








    I got steel tubing at the steel yard. I cut and welded the cross tubes into the roll cage.



    The lower front tube that is welded on the roll cage is the top aft bar on the Yamaha stock roll cage. I cut the mounting brackets off the top aft bar of the Yamaha stock roll cage and turned the bar upside down and welded on the lower front roll cage






    I added these bars to the back of the roll cage.


    I had my neighbors pull the roll cage off the buggy set it on the ground. At this point the roll cage is only tack welded together. I did the finish welding with the cage on the ground. I had a neighbor hold the roll cage at the angles I needed to do welds.

    I welded the radiator mounting brackets to the back part of the roll cage, I welded these brackets on the ground, I took measurements for the radiator while the cage was still on the buggy. I set blocks of wood on the ground to set the radiator on to get the radiator in position, then I built the radiator mounting brackets and welded them in place.
    I put weather stripping on the top of the roll cage where the roof panel will touch it to stop the roof panel from vibrating.






    I got a piece of 0.08 inch thick aluminum sheet I got at the steel yard to make the roof panel. I used DZUS fasteners to hold the roof on.

    I made the window nets frames by welding 0.5"x0.5" square tubing together, I used door hinges for the top pivot points, I made some spring loaded latches that lock it in the down position. After I get the buggy setup all debugged I plan on redoing the window nets so that the window net frame is part of the door, so when I open the door the window net will open as a one piece door and window net assembly.

    You can link two master cylinders together so one or other master can operate a brake caliper.

    This youtube shows how stunt bikes use a handle bar master cylinder connected to the rear brake foot master cylinder. They can use the foot petal or hand lever apply the rear brake

    If want to have foot petal brake connected to a hand brake so a normal person can use the foot brake and handicap person can use a hand brake on the buggy, you can use a master cylinder with no reservoir on the foot brake like this
    http://secure.chassisshop.com/partdetail/712-5-8/
    run the brake line from the hand master cylinder and connect it to the top port on the foot master cylinder where the reservoir would normally connect.



    In some cases you be able use cutting brake master cylinder , they may not work for you depending on how you want the braking system to work.

    I am not going to be able to get the KLIKTRONIC electric shifter or PROSHIFT electric shifter to work on my 2016 Yamaha YXZ1000. The KLIKTRONIC electric shifter or PROSHIFT electric shifter systems do not produce enough force to shift correctly. I started looking into converting my 2016 Yamaha YXZ1000 to be able to use the 2017 Yamaha YXZ1000 Sport Shift paddle shifter.
    I looked at the online OEM parts. I compared the the part numbers of 2016 to 2017 sports shift and found all the parts that changed. About 90% of the transmission is the same , things like the shift drum changed, one of the shift forks changed, the inter clutch hub changed, there are changes in the clutch plates and some other parts. The following is need engine ECU , transmission control unit, dash display, wire harness, electric clutch, the center console shift box assembly , gear position sensor, and other parts. On the Rocky Mountain ATV OEM parts site the grand total came to $6250.00 It took me 11 hours to comparing part numbers for every thing relating to the sports shift function.

    I have ordered all the parts to convert my 2016 Yamaha YXZ1000 to the 2017 Yamaha YXZ1000 Sport Shift paddle shifter system. I have started removing the transmission from the buggy. Once I have removed the transmission I will have to disassemble it so I can change the shift drum and one shift fork and few other parts.

    Yamaha says the parts will not be available until May 2017, I ordered the parts in January 2017. Being able to get Yamaha parts has been problem ever since I got my Yamaha, this has been a big problem. I always raced Honda's and getting parts was never a problem.

    I got the parts from Yamaha and have rebuild the transmission and installed the other parts. The Yamaha Sports Shift transmission works great , the paddle shifter is easy to use and I am happy with it. I am not going to show much of the install steps , I am going to show mostly the steering wheel



    The green paddle is up shifting and the red paddle is down shifting, I all so have buttons on the steering wheel that will shift





















    I got the 5 speed manual transmission with a manual clutch model when they first came out thinking I could install a after market electric shifter , but could not get it to work. Nine months after I got mine, Yamaha came out with the Sports Shift with paddle shifter with auto-clutch. For a paraplegic the Sports Shift would the best way to go.

    I'm unable to view most of the photos. There must be a problem with Photobucket?

    To get good brakes I am going to have to install a GM power steering pump that is driven by a engine fan belt to power a HYDRATECH brake booster (also called Hydro Boost). The HYDRATECH brake boost is the most powerful brake booster you can get. The first thing I need to do is install the power steering pump. I need a way to mount engine fan belt to drive the power steering pump. Yamaha sells an Alternator kit that has the shaft and belt pulley that mounts to the engine. Yamaha does not sell parts of the Alternator Kit you have to buy the the entire kit.


    This is the Alternator generator.






    Here I am building brackets that will let me mount the the power steering pump similar to the Alternator generator.




    This shows the drive shaft and pulley from the Alternator kit mounted on the engine. The kit also has rubber oil lines to reroute the engine oil lines.




    This shows the Alternator generator bracket mounted on the frame











    I welded a another lug to the bracket to support the power steering bracket

    The power steering pump I am using is HOWE T/C 1500 psi pump part number 210. This pump has a max rpm of 6000 rpm and the Yamaha rev's to 10000 rpm. I used the alternator kit pulley on the motor but needed to use a larger diameter pulley on the pump so I do not over rev the pump.
    https://www.howeperformance.com/parts/tc-pumps/

    This is the 4.5 inch diameter pulley I used on the pump, HOWE T/C V-Drive Pulley part number 305
    https://www.howeperformance.com/parts/tc-pump-pulleys/

    If you order the pump from HOWE they provide information about the pump and the hoses you should use, its helpful data.

    This is a link to the power steering system layout for using a T/C Pump and Hydro-Boost brake booster.

    Use Chrome for a browser and the pix show up.

    I’ve put it on both the Windblows and Mac and I can see them. Can’t see anything on Safari.

    The Power Steering Pump needs fluid reservoir tank.

    The first reservoir tank I tried was PSC reservoir, see the link
    http://www.pscmotorsports.com/motors...kes-21201.html





    The problem I had with this reservoir it keep spitting oil out the vent and covering the back half of the buggy with oil. I talked to PSC about my problem they told me they sold a catch tank with a rollover valve that would solve the oil spitting my problem. So I installed it and but it did not help the reservoir was still spitting oil all over back half of my buggy.

    I think the PSC reservoir is poorly engineered and that is the problem

    The HOWE power steering reservoir solved my problems I was having with the PSC Reservoir , the HOWE reservoir looks to be much better engineered. See the link, this is the way to go
    https://www.howeperformance.com/part...ers-and-fluid/ it is reservoir part number 1010
