I just finished completing my ear shave on my bike. It went very well and I'm very please with the results thus far, but I'm having a little problem. I cleaned both carbs out completely, synced the carbs, and turned both air/fuel idle screws out 3 turns. I've also tried turning these back in to 2.5, but it makes no difference.
Under the guidance of Lance (Thanks again for everything!!!) I installed 42 pilot jets and 145 main jets with 2 needle shims under each needle.
Bike starts up and idles great! Under full throttle the bike feels like it moves great. The problem comes in when I'm cruising at around 50-60mph. It feels (and sounds) like it's mising, cutting out, hesitating. At first, I thought air was getting to the vent hose, so I moved this way further back BEHIND the battery, no change here. That wasn't the problem.
On the way to work tonight, I thought maybe I'd give it some choke and see if this changed anything. Under full choke, cruising, it seems to stop the surging problem I'm experiencing. Would this mean I'm running too lean and need larger jets? I pulled the plugs, all 4 look about the same, and are light tan, they almost do look too lean, but I just don't know enough about carbs to fix this on my own.
I believe, (hopefully I'm right
) that I'm running too lean. I don't, however, know which of the two jets, the pilot or the main, that I need to enlarge?
Any suggestions? Thanks for any help that can be offered
