Motorbike not climbing steep hills

In the rack by 10:30 up at 6:00 LOL

If your carb has a idel jet on the side it could need to open up a bit, yet they are realy good carbs. Also you need to be running high test gas preferably without oxygen. Regular gas will turn to water in the bottom after setting for a few hours..............Curt

Try a bit smaller primary pulley. What type belt have you?
The basic setup is sound & looks good. A bit of pitcher's
rosin or talc on the belt will help slippage.

premium 91 gas?---That's right non oxygenated if you can find it....take a small pan of 87 and let it set for a few hours and you will see water forum at the bottom.........Curt
