I finally got around to doing this install on my Moto Cheetah. It should be similar for the Roketa types as well. I used the FB8 manual and the Joyner service manuals for references. It went something like this:
1. Disconnect the battery ground
2. Remove wheels and shocks
3. Remove exhaust system
4. If applicable, flip up the gas tank or otherwise remove for more access
5. Remove starter (I just hung it off to the side rather than disconnect the wiring)
6. Remove coil wires at terminals - just to get them out of your way
7. Remove the clutch bracket and lever assembly from the transmission. -Do not remove the fluid line; just bend the whole assembly up and out of the way.
8. Drain the transmission and pop off the axles
9. Remove the transmission to frame plate - located at the rear of the trans housing. Four bolts, two on the tranny and two to the frame.
10. Remove the two M14 bolts on the bell housing top
11. Remove the M14 bolt located on the front side center. (Exhaust manifold side)
12. Remove the nut located above the right side axle stub
13. Remove the lower dust shield - two M6 bolts, one each side of the oil pan.
14. Make sure everything is clear and slide that bad boy out.
Reverse the procedure to install the new one. The upper dust shield will be loose as the trans pulls away. Make sure it is lined up when installing the new trans.
The Joyner 800 manual shows a clutch replacement procedure. It is on a 650 motor, but the trans removal part is the same. Check it out here:
I also added some new rubber. ITP Holeshot ATR’s front and rear. The 26” tires net out to 25 1/2” rear and a little over 25” front. I think they fill out the looks a bit better than the stockers. They are a 6 ply radial.
One last thing is the addition of a Uni filter wrap on the K&N air filter unit. Cheap insurance for you desert guys.

Hey Mick ,
I've been waiting for Venom to call me for the trani. also Thanks for all the info. Mike - Slimefink ,had replaced has recently and I think he said it makes a huge difference. Let me know what you think
Mick with the power increases that we are all looking for on these 800cc engines and all of the great upgrades you are making is there a heavy duty clutch out there for these? I am thinking I want to make some changes to the GK-32 but I want to make sure that the clutch can be upgraded as well! Any ideas? _________________ Randy

the trans swap makes the buggy perform alot better, and with the re-jet and muffler upgrade the buggy gets with the program.
I can see a shaved head and weber carb swap and port job in the future, but for now it puts smiles on the wifes face, and after all is said and done thats what really matters.

Hi Randy,
At this time I have not had any clutch issues. I'm thinking that since the clutch was designed to be used with a much heavier vehicle, as daily transportation (aka MightyBoy, Alto), that it will survive in the much lighter buggy. So far, no sign of any problems. The new tranny swap can only help as well. If I do need a replacement, I'll get another stock unit and use the old one to try and match up. But, I hope that won't be for quite awhile yet. Regardless, it's not like I'll ever get 100hp out of this puppy, so I believe the stock cluch will be adequate for the power levels that can be had from the FB8 design.
I look forward to reading about your modifications to the GK-32.
Later...Mick
Joe,
It's like Mike says " it gets with the program". Here is my brief review. http://www.buggynews.com/topic7946.html
You will not be disappointed with the swap.
Mick
