My 107 was running rough from the day I bought it. Came with 295 intermediate an 72 main. I replaced them with 32 76. Made some difference but not acceptable. Changed the 32 for a 31. Didn't help.
Changed the 31 for a 33 and that really did help. No popping, backfires or coughing out the carb. Before I couldn't ride slow in 1st gear because the bike would stutter so much. Now I can ride it slow in 1st gear. It still stutters a little but not like before.
Going through the gears is a smoother operation.
Problem is it's still not right.
It seems to be with the rear pot. The front fires clearly and regularly. Doesn't miss a beat. The rear pot isn't so regular or clear. It seems to get an extra soft beat thrown in which is making it fire slightly unevenly.
Is it the coil? timing? I really want to getting running sweetly.
New plugs in and replaced vacuum caps. Float bowl vent plug in our out makes no difference.
What can I do?
As going to a 33 jet made a good improvement I'm ready to go for a 34. Going less than 33 makes it worse.
Help and ideas appreciated.
