if I can find the tools I am taking out the carbs next weekend and given em a good cleaning. and I think it is the jets because I read the main jet doesn't kick in until 6k rpm and that is exactly when things smooth out. so I think they need to be cleaned alot of bogus things were told to me when I bought this bike so now I am dealing with it. oh well I am enjoying it and I should be all set for the next bike I get this bike is a very good learning experience both in riding and repair.
ok got stuck with the kids this week while wifeys at work so gonna pull the carbs tomorrow hopefully and try to clean em out. I can find spray cleaner easy enough but finding the dip/bath bucket I can't find anywhere. so my tools will be spray an old toothbrush and a small wire brush (any suggestion on wire to go in jets I am thinking thread) and a can of compressed air. plenty of screwdrivers, wrenches etc. and a whole lot of patience and a claymers manual and you guys so keep an eye open may be screaming for help. well stuck in the house all week so I figured can't ride anyway so why not yank and clean.
