pit bike engine

[coolkarter]

hey i was thinking of putting a pitbike engine in my kart (pitster 125) im getting the whole bike so im also going 2 use the brakes etc but im wondering of how i can prepare it

take the old motor out... maybe start working on a shifter lever. and clutch pedal (assuming its manual)

then once you get the caliper and everyhting else you can make brackets or cut them off the bike and drill motor mounts.

also need to figure out how ur gonna mount the tank.

im going to strengthn the frame first to handel the extra power of the pit bike motor and with the shifter would i push it up to shift up and push down to shift down

might want to check, all bike trannys are different.

you sure its even a manual tho?

What kind of frame do you have? If it's small, you could sit next to it, rotate the shifter arm up, and fab a longer arm. I bought a motor like this from a kart, the seat was to the right (when looking at the front) and the motor on the left. The shifter arm was extended upward with 1" OD pipe and the bike's twist throttle was on the shifter arm. So drive with your left hand, throttle and shift with your right, clutch with your left foot and brake with your right. Interesting, but practical.

that would take me a while to get used to!

So you only had one hand on the steering wheel? Dosent sound to practical to me...

You don't understand the guy I bought it from, it was a rough part of town, he was looking BA and revving it high in neutral. As long as full lock is less than about half a turn, it should be do-able.

no my frame is designed for have a mid/rear engine and its a 125cc 4 stroke with a 4 speed manual with manual clutch it can get up to 60mph its from a pitster pro i might try what redsox985 suggested would that work with a mid engine?

 

[coolkarter]

how would i make the shifter linkage would i just take a shifter cable and attach the shifter to it?

 

[redsox985]

Could you make a suicide shifter with a hand clutch? So that you gas with a foot pedal then let off and clutch and shift with some type of linkage? Like this (but moved up by the driver, not back on the motor):

 

[coolkarter]

ya i could easily do that thanks for the idea

 

[Bluethunder3320]

i would make 3 pedals, (clutch, gas, brake) and a lever that is just a solid bar you push up and down.

 

[coolkarter]

what about a footclutch as in a dirtbike would i just put a spring on it?
