XS650 Addict
Hi everyone, This is my first time posting but I have been appreciating the collective wisdom for awhile now.
My situation is this: i have a 1977 xs650 that was running great. It has new OEM air filters. I decided to change to MikesXS commando style mufflers. After swapping out, the bike started to stumble in 1st gear or neutral, but really lunged forward when shifting into 2nd and ran fine from there.
I decided to go to a size 27.5 pilot jet and 127.5 main, one up from stock because all I changed was the mufflers, no pod filters. Is this correct? It doesn't seem to have changed the problem. I tried to adjust the fuel/air mix by the dead cylinder method, and the bike runs OK on the left cylinder and plug, but I can't get the right cylinder to fire at all. When I hook up the left plug & wire to the right cylinder I get some backfires through the carb, but nothing else. Did I screw up the jets? Is something else off?
Thanks for your help!!!
