I finally got a chance to work on the bike. I put one of those inline coil tester in place between plug and coil wire. Sitting on bike the left side cut out so bad the inline tester wasn't even lit up, also I noticed the left pipe wasn't half as hot as the right side?
I'm already down from a 260 main to a 240. Pilots are 30 should I try 27.5? Plug does look a little rich. I do need to check pick up gap. I got the bike from a buddy of mine and it sat for a while. After it cools bike runs fine again for about 10 or 15 minutes till it warms up again.
Guys bike runs fine for about 10 minutes till engines gets warmed up. Stock motor good compression, stock carbs jetted to fmf specs, +4 timing, fmfs, and K&N pod filters. Kinda feels electrical to me. What y'all think? Any help is appreciated.
