DT1 flat track project

The piston I'm using is Wiseco part # 234M07100.

Here it is with a stock piston for comparison. I'd read the Wiseco pistons were heavier than stock and was curious what the weight difference was between the two so weighed them on my digital scale. The Wiseco is a brand new 71.00mm piston and the stock one is a used 70.00mm, so not a direct comparison, but the stock piston (with pin, rings, and clips) weighed 300 grams, and the Wiseco (also with pin, rings, and clips) weighed 305 grams. The Wiseco piston and pin each weighed 5 grams more than the stock part, but the rings and clips weighed 5 grams less, so just a 5 gram difference total.

Getting the top end buttoned up, I'm going with bare aluminum on the cylinder and head.
