sandblaster:
Just go slow and watch your plug color..

So I changed a bunch of stuff and came pretty close to blowing the bike up. I took off the PC pipe and switched to an FMF Fatty and rebuilt Turbine core. I also added a 10mm reed spacer. I changed the jets to 165 52. Sandblaster had a great how to and I made a plug and set my float level.
The bike was idling really high despite the screw being all the way out. I had leak tested the motor before install and I sprayed wd40 around the carb intake boot to rule that out. So I thought I might be lean with all the changes and re installed the 167 55. The bike still idled high so I blipped the throttle so see if it would settle.
Well that was a bad move because the throttle went crazy. I couldn’t shut it down with the kill, shocked the s**t out of myself trying to disconnect the plug, and finally got it back down after twisting the throttle again. The throttle was not stuck and after shutting down the bike I had fuel dumping out of the overflow.
I’m not sure what went wrong I assume the float stuck and the motor took off. I don’t know if I should try and replace the carb or some parts. The float needle looked great and I verified that it was working. The float had been bent a few times but looks ok. I’m hoping for some advice. Don’t want to start it again with this carb.
Foxx4Beaver:
have you verified your cable routing is correct?...no tight spots when you turn the bars from side to side?
is the upper adjuster at the throttle housing set correctly?...you generally want an 1/8" of free play at the throttle.
check were the cable goes into the top of the carb....there's two different types of caps...
my old carb used the kind that uses the clip that you slide into place that locks the cable in...
my new carb came with a cap that didn't use the clip, but I used the old cap with the clip on my new carb...as I feel safer knowing the cable is locked into the cap.
Pmcg:
yea thanks Fox checked. Its not the cable I'm pretty sure its the float. I'm thinking about replacing the float and needle and seat or maybe just ordering a Lectron.
