Scooterotica

Running a slightly tuned ts1 225 with 35mm mikuni ,ram air filter and jl4 pipe, fine when cold but revs high when warm and when slowing down seems to oscilate??? Can't set tick over at all when hot? Any ideas?? To be honest looking for a starting point before i start to strip everything. Runs fine through rev range?

Cheers Gents

Sounds like an exhaust leak..?

Could be a few things that one. Could be lean and as motor heats up the effect is leaner hence the over revving.. or somewhere the motor is drawing in air. It could be from virtually anywhere. Head, base, seals, mag housing or even a crack somewhere.

Pilot jet too small, blocked or just requires setting the air/fuel screw??

had the same problem but with a 34 dellorto turned out the filter in the carb was all clogged up,changed allsorts before i found the fault

Happened me last month after i refitted the carb.....tightened up the hose at the back of the Mikuni and hey presto....problem gone!

Thanks gents

Will give it a strip down this week, check everything tight and no leaks

Thanks again
