Sounds like it could be fuel delivery problem. Are both fuel taps on? Do
you have the stock "x" crossover fitting. You might want to check that
the taps are both flowing fuel freely. Do you have fuel line filters
installed? Check the filters underneath the banjo fittings, too. If
everything looks good here, it may be your jetting. Try going to a bigger
main jet.

Good Luck!

soon as I get them back. It has been years since I had even driven the
bike. I went for a 50 mile drive this evening and everything was fine
until I got the bike above sixty mph. It seemed to run and idle fine at
lower speeds but on the highway it would bogg down. If I rolled the
throttle back at sixty instead of accelerating it would actually just
slow down slightly and not accelerate unless I gently rolled the throttle
on. Is this common? I seems to me like it use to have alot more power
at the upper end. Does anyone have any idea what the problem could be?
Are the carbs missadjusted? I hope this is descriptive enough if not
please let me know. Thanks for any help.
