Hi, been a while.
I ran across a liquifire motor(looks to be 77)and was thinking of putting it in my 77 Cyclone. Do You think this is an ok idea or leave it alone? Just looking for opinions.
Thanks

Any 100mph speedos?

Hi, Been a while since I've been on here. Been doing a lot of sled work. Today is the first ride of the season on the JD. I have been riding the others though. I got a gopro camera and am still trying to figure it out. I made this video yesterday on Big Muskego Lake of speed testing. Bad camera angl...

Got it to run! on right cyl only. Ran great for 1 cyl.
Good spark and fuel Maybe bad crankshaft seal and or injector. Left side will not fire.

Replaced it and sparks like crazy. still wont run but will fire on first pull. Nothing after that. Floods bad. any ideas?

Yes, throttle over ride system.
Make sure it work good. If mine didn't, I would need a new garage door. I also use BR9ES plugs. Works great. Wildcat will run tomorrow!

Just bought a non running 94 wildcat 700efi. After a few tests I found the stator to be bad. I did find one on web and ordered it(pats small engines). I just hope I can replace it without pulling motor...

I have a 98 which I bought 2 months ago. blew the motor bottem end 24 hours after I bought it so bought a used motor and runs great. Motor blew due to #3 carb fuel line pinched in half and oil is mixed in fuel pump. Get 1" studs (alot) Runs perfect now and very fast.

OK now runs great and put 144 studs in track. These were woodys gold digger .875. They helped but should have got the 1".

If pinch bolt is off or loose, try an air hammer on the spindle top. Maybe spread the arm with a chisel.

OK had BR10ES plugs in it and fouled one last night. Now BR9ES and ran great but lighter then I like. Piston tops look fine but plugs very light brown. Maybe go back to the BR10ES? Any thoughts?

I guess its supposed to be wrapped around the chaincase. Bad design but dealer service dept said that too. Runs great light brown plugs(would like them darker).
Now speedo crapped out.

huge air leak?

Getting it back together now but want to see if any of you can tell me how to route the pull start rope. I know this not a yamaha forum but the smartest group ever.
The rope was wraped around the brake assembly and wore grooves in it. I just cant see a clear path.
Thank you.....

I never saw such talent. I cant wait for the finished sled!
