Also got a different front fender since the Preston petty didn't fit my new mx clamps. It's a KW with the old style aluminum support.
It's nice to have both of my fenders silver again

Dont hold your breath on the ride report, were having a big winter here and im just happy that I can finnally roll it around the shop.
Later this week Im sending out my cylinder for porting and a fresh piston. Getting the head rechambered and milled and the flywheel lightened. Maybe then I will be satisfied :Ugh

I don't know the part numbers but I remember they were made by All Balls racing and cost $30-35 bucks. I think I got them on eBay. They are real nice and they come with new bearing cups you have to install in the head tube

I pulled my top end off and found out it was already heavily modified by trinity. They scribed trinity racing mx on the cylinder so that may be mx spec porting? The head had some kind of spiral milling on the chamber. I sent it all out anyway to ken oconner racing since I had low compression and he can check out what I have going on. He does a lot of blaster motors and after talking to him trust he can get me back up to speed. He is doing my flywheel too. Sorry forgot to take pics before it got mailed.
