nightmare part 4

i have tryed to jet the carbs down, and now my #2 &3 cly isn't hitting, i am at a loss have taken the carbs back off and haven't found anything ovbious as to why i have lost 2 and 3 realy don't know what to do next my bike has t.k. carbs so i don't know who makes them, have called some shops and one said my bike has mikuni, and the other said keihin.being that my carbs are off i would like to put bigger pilot jets in because of the fact the bike would pop when i let off the throttle. thanks in advance for everyones advice it is not wasted.

Lost 2 & 3 meaning?

Keep in mind, 2/3 are on the same coil, sure it's not electrical?

what do you mean by "not hitting" if they're not firing its electrical, u do know 2 and 3 fire off the same coil right???

im sorry for not being clear i am getting fire to the plugs just not running on them cly.

damn dude you type faster

did u mess with the timing plate any, 2 and 3 also fire off the same set of points, u could get fire but worky, if not take em carbs back off and go throuh em again, check passages, bench sync, etc,etc

"i am getting fire to the plugs " but correct ignition spark is the question....

i have my carbs off and being that my bike would pop as i let off the the throttel i figured id put some bigger pilot jets in. but i can't find any . my bike has ele ignition and i have never touched the timming plate but i may try this time . my main thing is i need to check the coil and plugs today.so it sounds like i have my work planed for today. thanks.

be meticulous, do ONE THING AT A TIME, make a list, AND DONT GET EXCITED good luck :woohoo:

Often just a simple pilot circuit enrichment will eliminate popping on deceleration.

A different pilot jet is often unnecessary.

Simply use the pilot adjustment screws.

Each carb has its own pilot adjustment screw.

An air leak (intrusion of outside air into the air-fuel mixture being provided from the carb to the engine) will also cause popping on decel and also a racing idle.
One typical leak site (of several possibilities) is at the carb holder (loose clamp for example) or cracks in an old worn out carb holder.

Good Fortune!

+1 Absolutely. Turn those mix screws, and turn up your idle. Check by misting some water on the pipes, to see if the 2-3 start running again. If they do, then your sync is probly terrible. If not, then you gots another issue...

Make sure fuel levels are all correct/the same, and make sure pilot passages on carbs are flowing fuel correcty by spraying cleaner through the pilot jet opening, and watching it spray in the bore.

Good luck!

you was right my whole problem was in the sync. i spent all day tinkering with the bike,and found that it was way out of sync. next good day i will put the gages on to make sure im on point.
