Jeff Grawbarger's KX500 on NOS

Post by Sandblaster » Mon Jan 11, 2016 3:36 am

Jeff contact me about rebuilding his top end that he uses for drag racing and he runs NOS :shock:
When I received the cylinder I was surprised to see how little it was modified :?:
Then again when you introduce some spray all sorts of good things can happen, or bad things :lol:
The port timing is stock and we will leave it stock.
But everything else is gonna change.
We will do all the normal Team Green mods, Motorrad mods, and a few of our own mods.

Ok... here is some things to ponder 8-)
This is your standard KX500 Sub port..

So, you think you can get a cylinder like this and go out and win like Jeff Grawbarger #151?
Not likely, Jeff is a 5 time KX500 drag champion and 7 time champion on his YZ250.
Needless to say, he knows how to set up his chassis and tune his engine.

One other item of note, Jeff has not even touched the NOS button yet this year and he has beat every bike NOS or not that he has raced.
Yeah... That's a keeper :lol:
