Should I up the size of my jets?
I purchased a '93 a couple of weeks ago and it ran good when I test drove it. Liked it. Bought it. As soon as I got it home it was running rough and sputtering around 3k - 4k rpm. Read lots of threads on here = I added SEAFOAM because...well that was the answer (no matter what the quesion was...well almost anyway.)
After SEAFOAM. Bike started smoking but running better. Mostly smoking from the front cylinder exhaust...and I mean at times A LOT of white/grey smoke. Inside exhaust from front was wet; inside the exhaust from the rear was nice and dry. Smoke/Exhaust does not smell sweet like coolant but more like fuel. Idled okay at first but then I drove it and more sputtering and popping....then it wouldn't idle. Would only start with throttle opened about half way. I've read about this kind of problem on here and figured the SEAFOAM loosened something up and carbs needed a good cleaning. (IN PROCESS NOW = carbs are off the bike, tank drained in case of bad gas, petcock removed for cleaning)
Skip to here for the real question...
My question, for now, is that since the carbs are off the bike, should I change from the stock jets that are in there to larger size? The bike has the stock air box w/ears setup but it has Cobra pipes.
There will be more to come as I put the newly cleaned carbs back on the bike...
