Hello Everyone,
So I own a 1975 XS 650 and I have new mikuni Vm34's that have been rejetted I have basically rebuilt everything on it. Its been running great I have been ripping around on it for 2 months about 3 to 4 times a week. I took a 30 mile ride with some friends and we were getting on it my bike was running great, then at the end of the night it was sputtering at half throttle pretty consistently and by the time I got home it was sputtering at 1/4 1/2 and full throttle. I let the bike sit for about a week ( apparently I thought it would magically disappear) I took it out tonight and and seemed to sputter minimally at 1/4 to half throttle. Its so bizarre that it ran awesome for 2 months riding it al the time at 1/4,1/2 and full throttle. I also put aluminum intake boots on it but maybe that long ride loosened up the bolts and I have a leak? Any advice would help me close out the summer in style!
