Someone please confirm before I beat my head on a wall.

Sooo... the bike has had some down time as a result of some "cosmetic upgrades" utilizing the 750 bike I got for parts. I'm waiting on an LED brake light because I ditched the banged up sporty fender I cut up for the bobbed look... Still didn't get it, and I'm sick of waiting for things, so I made a brake light utilizing a banged up turn signal housing, the red plastic from the stock light, a grinder, some epoxy, and ingenuity just to get the bloody thing on the road for the weekend.

So tonight, I fire it up, and my new mac exhaust is leaking... minor leak at the weld... why? I do not know. I will patch that up... On the other side, however, the 4th cylinder is playing dumb. I can physically feel it go in and out going down the road. Pilot Circuit? Anything else I should try before peeling the mother loving carbs off again? Before she hit the "shop" for a couple weeks, the carbs were rebuilt, colortuned, synced, and the plugs looked good... obviously, I haven't had time to go through that again, but something had to happen, right?

 

Update... just threw a colortune on it before bed... no flame, until I get the rev's going... then it will fire. The mixture screw is useless.

 

Sounds like a peice of junk got in your pilot circuit.

try starting the bike then covering the carb and then nail it.....it will try to suck whatevers blocking up the carb.

 

reclean the pilot circuit. I used the old earwax washball and flushed it out with CRC brake clean ( it is rubber safe)after undressing all of the ports and passages. I then reflushed the carb fuel passages and replaced the fuel filter with a fresh micron filter.
