Hay Gordon !
95 is stock main jet size right ?
both carbs have 95's.... I am thinking that changing them to 100's may well cure my problem
....
I do know that because of the EPA they leaned out bikes so lean they are lucky to run at all.... and at my altitude maybe it's reacting worse than at sea level
....
going up in altitude usually makes it Richer though..not leaner but the symptions I'm getting is it's too lean not too rich...so I am confused and trying to figure out why it's screwing up on me....
I think larger main jets is the simplest next step and just see if it likes it better
I had put 2 tiny washers under the jet needle before when I was fiddling with it trying to get it to get past the flat spot so I took those out just now and we are totally back to stock.
I think I'll try the next size larger for the main jets and then do a color check on the plugs if it doesn't have a flat spot any more( which I hope it won't!)
....
I bet you larger MJ's will cure the problem ! i have a feeling !
