I've ridden a monsoon before. They run dead even with z50's. Post pics when you are finished. How are you going to set up the clutch and shifter?

[ny300exrider]

thats gonna be crazy hahah..keep us informed

[250rmike]

if we move the rear shock mount out farther on the swingarm a few inches the frt. 250 shock will mount up. we are gonna cut and weld the frame and gusset it. its a buddy's little bro's bike boy is he gonna be suprised when he gets back from where ever he went with his dad(cant remember off the top of my head) im not to worried about the kickstart and shifter. my main concern is the pro circut pipe fitting in right. for the frts. were gewtting another friends boss to custom extend the a-arms and we are gonna mount up the 250 frt shocks. we also have a z50 motor that were gonna rebuild and put on a go kart. we followed the little quad in a car the other night and it maxes out at about 35-40 on the stock motor i wonder what it will do with the bike motor. i might even bring it to some nationals when we get it done as a pit bike

[250rmike]

accually i was gonna custom make a frame and put all my r extra r stuff on like a-arms axle swingarm steering stem and whatever else i have. but my friend had this so we decided to put it on that frame. just gives us something to do. im gonna custom make some things like footpegs and some other things

this was going to be my summer project untill i found out i had bills to pay :D How are you going to do the shifter. This was the only problem I saw when i wanted to do it. I still might do it so keep us updated so i know how it goes :D

[toby400ex]

i would worry alot about not being able to shift, but i guess you could rig up some kind of lever.

[250rmike]

the frame is not that wide so i should just be able to leave it howit is but if we cant ill prolle make an extension onto the motor shaft and go from there my biggest problem is gonna be the pipe i have really no worries about anything else except getting everything lined up perfict cause my friend likes to half ***** alot of things

[jello]
