I think it would have to. Next time I have the head off I'll measure the port height closed vs open. My piston to head clearance is .060"

It is paradise. My wife and I spent our honeymoon up there with the wheelers.

Great Video!, Thank You for sharing and it looks like a great place to camp & ride, lucky guy.

We have a area fairly close to us that reminds of that area, a bit less grass and more trees but it reminds me of it.

I would leave the jetting, any bike or trike that has that much power and snap with a black plug is a Winner! I have never been a fan of the creamy mocha colored plug quest on a two stroke.

You will have a wider spread of power with less compression and it sounds like you have a dome to play with.

The power valve has no effect on compression tests for several reasons.

I have not played with the timing yet. It's just a hair retarded from stock.

Been awhile. I've got all the kinks worked out. She handles great, pulls hard and I love it. I don't believe the PV added too much but it's fun for it's unigueness. This summer I race MX at trike fest, 2 TT races localy and trail rode a hand full of times. Currently i'm setting her up for ice racing. Here are some of the videos.

This is an amazing build.... I am going to use several of your techniques on my build... hope thats ok! I hope I get to see it in person one day

This thing just keeps changing. TT is the current flavor. I'll be lowering it 2 inches it the rear tonight. Top mount tank will be delivered Monday. I'm running the yellow plastic until I can find a left rear fender stay.
