Its alive.... - Edited... the title... Me = dumbass...

[The Buddha]

Its alive... not a GS but still y'all helped me fix it... Its my 535 virago... It ate its pickup trigger... and I wasn't able to diagnose the rear cylinder non spark issue fully... hence I didn't want to buy the trigger and test it... in case it wasn't the problem... so I yanked it off my friends 750 wiht broken case... found out its a different angle V and the case is slightly different... and hence I cut out one of the trigger from its plate and spliced it into mine... yea I did manage to get the perfect angle and get it right where it is supposed to be. That got the bike running on the rear cyl ... and its back to its old tricks... of not running too well when the motor temp isn't fully hot yet. Its missing on the rear cylinder. It might just be lean... I have keihein jets in the mikuni carb... but I have to check it and see if it needs mikunis...
Cool.

OK Mine is all stock... I have the float level cranked up really really high... as high as it can get wihtout running the risk of not closing at all... The thing seems to behave fine in summer... Making me wonder if its carb icing... cos the 90+ have exhaust heat risers... heating the carbs. The Jets are 145 keheins in mikuni carbs... they fit fine and are probably like 140 mikuni's... 1-2 sizes smaller... still the floats are ~10 mm higher than they have to be... its still lean. I know its lean... cos its better when hot and I lowered the float yesterday... and it was much worse. BTW what jets did you use... running bad is one thing... mine loses the rear cylinder... runs just fine on the front. I stopped for a minute... and it cleared up. That was after riding 3 miles to the gas station on a bike that was warmed up well by idling with the choke. Anyway what jets did you have in it... and were front and rear same jets. I think in 90+ bikes thay had different jets front and rear.
Cool.

I live at 3,500ft elevation and I actually had to lean my bike out even after adding the pipes. But you are right, the main jet is different for each cylinder. Unfortunately I no longer have the bike and don't remember what sizes they had. I only know I went down one size in each carb. You might check with a dealer to find out what the original jet size is for each carb and go from there. Mine was always very finicky about spark plugs. Have you tried running platinum plugs?

Platinum will be the next thing... The bike acts lean though... not rich.
Cool.
