Hi there i recently got a super 8 4t that needed fixing up. I have done a fair bit of work which i will list in a sec but i still have a few problems with the bike. One is with the idling. The bike now seems to be set at the right mixture(after following a forum post saying to get it to max rpm then set the idle so that the rear wheel isnt moving) And the idle sounds fine, and accelerates as id expect. But when it is left idling the rpms pick up and drop back down randomly on their own, and im not sure why. Another potential issue(though i am fairly sure this may be solved now since changing mixture) is that the bike would not start for a long time of trying with the electric start, not sure if this is a battery issue as it was almost dead when i bought the bike. After alot of trying it would start but usually with a jump starter battery attached.


The work ive done on the bike is as follows:
cleaned the carb(3 times!)
changed engine oil and cleaned strainer
new plug
new air filter
removed sports exhaust, replaced with stock.
new clutch plate
new variator rollers
valves adjusted
drained old fuel, cleaned out tank and fresh fuel added.
new fuel line

Any ideas what my problem is? The bike really needs a good ride to see if that sorts it out but its not moted or insured so thats not possible. Cheers for any help!
