Its been 10 years, boy has it been along time with my girl.
Just lookin' to see if you guys can think of anything I might of missed on this. Down to the last few things I can narrow it down too.
So I have a 1998 V-star Classic 650 with a KJS carb conversion. I have been tryin' to narrow down an issue with the rear cylinder running more rich than the front on idle.
I have checked the valve clearances 5 times. over the past year.
I have checked and re-seated the intake manifold 3 or 4 times to 100% verify for no leaks. It definitely has no leaks.
I increased the jetting on the idle to see if it made a change, it just made the system more rich overall, but no noticeable indications that is was fuel/air related from the carb.
AIS has been plugged using a AIS Plug kit So no leaks there.
Compression comes back as balanced and within range. (lower end of the spec but still within)
Runs fine on the road. However, once stopped, it will coughs into the intake or pops from the rear cylinder exhaust.
Front cylinder can carry the bike by itself with rear coil unplugged. Stalls and back fires from the rear cylinder if I pull the front coil plug.
Checked about a dozen times for a rear exhaust leak. Found a few sometimes, but doesn't seem to fix the issue.
Only thing left I can think of is to rebuild the cams/valves to 100% make sure it isn't them....
So before I take that step, Anything you guys can think of I may have missed?
I have been working on this minor issue for over a few years. It's quite an enjoyable puzzle. lol
