Ho Dude
I recorded a video but it's too big to upload....
discovered why the bike seemed ROUGH and was LABOURING a bit, even after setting up carbs. The rear brake was binding....
All it needed was a drop of oil on the brake pedal PIVOT and LINKAGE and now the brake is working perfectly...and the bike is running better than ever....
HAPPY DAYS....!
So.....taking carbs off, giving them a good clean and setting the butterfly valves all the same visually, and putting the pilot screws to factory setting...(two turns out) does a pretty good job for the amateur home mechanic.
