it look fast

It originaly started as 1987 quadzilla. This is a project I have been working on for a while. I race this thing every chance I get. I have been 4.31 in 300 ft dirt and 6.69 at 103 in the 1/8 mile. After every race I learn something new and I expect to go faster next time.

ive been lookin at the pics on the first post of this topic.
and to me that engine looks kinda fermiliar.
my uncle once had a yamaha RD500 YPVS that bike had the axact same engine.

the YPVS stands for Yamaha Power Valve System.
all 4 valves are controlled by individual servo's that are connected to the ignition.
they read the RPM's of the engine so they are always on the right point on the powerband.

its pretty sweet cause when you turn over the key to start is you can actualy hear the servo's move as they get into position for a cold start.
