By stock I mean stock no porting nothing except U4 which was used for all these runs even had airbox and used well oiled filter.Impressive and a record by far for unported 450cc stock stroke.Here is him pointing at record,Quad and him racing it today.

The video doesn't even do the roughness of the track justice. You had a choice, pin-it and hang on and hope you skip over everything or slow down and get beat to death.
Couple pics the fiance got.

Evols are working great. Quad is working great. Now I just need to get the body working great
Look for a Dyno run with the next phase in this build. Crower TI Valve extrusion ported head..............
With the 5hp gain from cams, I'm hoping the head will yield the same type of results and hope to see this quad putting out high 50's.
Final step in the project may be a high compression piston, but we'll se where we are at after the head as we want reliability as well with this set-up.

I would think with ported head and open airbox you might be knocking on the door of 60. Screamer of a 450

Oops sorry I forgot.This was last session.Notice how I moved the whole AFR up and down to find where the power was.Whole session only took about a 1/2hr.We really really have to get the RPM and Torque working on this quad.Comparisons are hard to do using speed.Something is interfering with dyno causing it to reject the RPM readings.On a sidenote I downloaded all the dyno runs ever there.Every make and model anyone want to see something let me know.
