So with all the action in this thread recently I decided to check and adjust my valves. Now im 99% sure I've gotten everything adjusted within specs, but when I just took it for a test ride it bogged down and died as if it was running out of gas. Could start it again with the petcock on prime but if i turned it back to the normal on position sure enough it died again a few minutes later. Also when I brought it back into the garage it smells like it's running too lean, a burnt kind of smell.
Any ideas on what I could have screwed up while doing a fairly straightforward maintenance?
EDIT: Just a tip to all the geniuses like me out there, REMEMBER TO RECONNECT THE VACUUM LINE TO THE FUEL PETCOCK. Problem solved
After adjustment, the bike runs much better. I'm getting a lot more range in the gears. It's pouring rain right now so I only went around the block a few times, but I easily got up to 30kmh in first gear whereas before I was lucky to get to 20 before the engine wanted to explode. Second gear took me to 55 rather than 40 like before the adjustment. Very glad I decided to do it today as I had just been procrastinating on it the past few weeks.
