Hi guys!

Picked up these little jewels and having a few issues keeping them running, the 1980 185atc will run and start good but when you run it out it wants to bog out, now this bike doesn't have a airbox just a KnN clamped on.

Now the problem child the 1981 185s ran after i cleaned the carb, added new plug cleaned carb and now it will run for a bit then just die, nothing. this bike has the airbox but the filter just crumbled so just cleaned upp everything. HELPP
