An Easy Fix

Some fixes are easy. Some are not. For instance, the Letta 250 has had a shifting problem that I have been unable to solve through adjustment and rebuilding. It has plagued me for years. However, the wiring problem was not one of these. A quick post to and response from the Maicoletta Yahoo! Group, and I got a suggestion: tighten down the body tub, since this is how the brake light and taillight are grounded. Fortunately, on the Letta this is but one bolt. Once tightened, all was well.
In other news, I lowered the needle to let in more air at throttle. This leans the fuel-air mixture to compensate for the relative lack of oxygen at high altitude. Smaller main jets are on their way to me from Bing America. The scooter feels faster too, though this may be psycho-somatic, as when a driver perceives better running after an oil change.
