    240 Big Bore kit re-jetting

    Thanks for the info guys. That is exactly what I was looking for. I just wanted a baseline to start at. I think I will start with a 340 main jet, keep the pilot stock, and put the needle at the fourth position down. As long as I don't have any other air leaks or anything, I think I can get...

    240 Big Bore kit re-jetting

    I think I have eliminated the air leak, I'll confirm that shortly. Plug chops? yea I need to do some studying on that, never heard of it but it sounds important. The TORS has been disconnected, and get this, the idle adjustment screw on top is missing- its just gone. theres now just a...

    240 Big Bore kit re-jetting

    Thanks for your help. Yeah, I am still trying to figure out how to go about finding the right pilot and main jet. I think I will start near 350 for the main since that is what you suggested. When I play around with these jets, what am I looking for? If I replace the main jet, what...

    240 Big Bore kit re-jetting

    I was guessing on the bore- over, i could very well be wrong on the .060 over, and by what you're saying, it sounds like I actually am wrong. I gotta look at the receipt. Unfortunately, I don't know what brand the big bore was. The guy I bought i from was certain it was a bbk, and he said...

    240 Big Bore kit re-jetting

    I bought it blown up, already with the 240 big bore kit installed. I just had it rebuilt and re-bored (i think .060 over the big bore). when I put it all back together, it started no problem, but would not idle. The throttle response was crisp, too, but I did not ride it so it wasn't under...

    240 Big Bore kit re-jetting

    I just bought a 2000 Yamaha Blaster with a TRUE 240cc Big Bore Kit. It has a stock carb, a DG pipe and an open airbox with a stock filter. I'm not sure if the reeds are stock (I cant find a name on them). I'm located in upstate NY (~1000 ft above sea level). With the choke on, the quad starts...

    clutch disengage shaft

    turns out, when the shaft pulled up and out of its seated position, the pushrood came through beneath it and prevented the shaft from being seated down in position all the way. I simply pushed the rod back through (after taking the clutch springs out of the boss), seated the shaft and put...

    clutch disengage shaft

    awesome this is excellent news, maybe there's hope. I was afraid I would have to rip the entire engine apart again! I'll look at it tomorrow. I'm starting to think that after it popped out maybe the pushrod stuck out slightly and is now preventing the shaft from seating down in its designated...

    clutch disengage shaft

    thanks for the reply - the cable is not attached yet. The lever did not come off the shaft, rather the shaft popped up and out from the case. I cant seem to get the shaft seated back to where it was. Its sticking up slightly more than normal. Also, since its sticking up more than normal...

    clutch disengage shaft

    I just finished completely rebuilding and reinstalling the engine on my '94 blaster. As I was installing the clutch cable to the clutch lever on the left side of the case, the shaft that the lever is connect to "popped" up and out of place. Now the lever doesnt have the resistance of the...
