Parking brake! There is a switch on the handlebar. If the lever does not fully return, the CDI is in limp mode and will not rev past idle.

Few hours of time and gas is worth shipping engine to a builder

Guess I feel compelled to offer my input. The first thing I might question is the mechanic. We may not have the full story but it sounds like the bike has a starting problem but otherwise runs good. A comp value of 60psi, unless you are on Mt Everest, would be pretty much not running at all. I would first question that value. Seen this tooooo many times where guys end up doing a total rebuild over a poor compression test. The adapter that screws into the head is just as important as the gauge. Personally, I would pull the pipes and/or the reed blocks to get a good look at the rings. At 60psi and those hours, either your rings are welded into the pistons, or you have no problem at all. If the ports were so sharp that they destroyed the rings in a couple hours, that usually leaves some evidence in the bore, or a quick feel will tell you. Yes, it is normal for the pistons to look a little "loose" from the top. The top timing edge of the piston is designed smaller due to how it expands when hot. A sharp mechanic can simply move the piston around at TDC and determine if the rings are welded or not. To me this sounds like a choke problem. Not pulling it all the way out to the second click, cross tube is missing, etc, etc. Something simple Brandon Mull Engineering

I have a set of white ones in great shape, also a rear if you need it. Sent from my iPhone using Tapatalk
