Bringing this back from the dead.
Tore down the top end with Degsy last week. The bore looked pretty good but the rings were fairly shot. Turns out (I'll get nomenclature wrong) the air mixture jet(?) Had the washer and gasket in the wrong order and the gasket had fallen off. Anyway, located the source of why its really running like crap.
I found a complete 120 kit for $119 online, which seems to be about 1/2 of what they cost, so I ordered it. I figure I can get that and a pipe for under 300, then jet the carb properly. Logic is if it makes 6 horsepower before, and it makes 6.25 after, that's a pretty nice % increase
Really, the jug just looked like crap on the exterior. Bent cooling fins, bad spray bomb job.
More decisions. I'll be running it up in Winchendon for starters, so o need to decide on wheels. If all I do is flat track, seems to be generally accepted that I can stay on the stock 19/16 and run trail wings. That said, I may be interested in running it at boxshop later on so swapping to the 16" front right away keeps me from buying tires twice.
Things are starting to add up a bit, as I'm looking at another $200 to put some adult sized springs in there.
