Quadzilla Powervalve

[DariusKTM]

I was told that the powervalve on the Quadzilla is adjustable.

I loosened the 2 retaining screws and then turned the knob on the left side of the cylinder counter clock wise to 1/2 position between the '0' and the '500'.

Noticed that I lost some low end torque but did not feel much more in the mid range.

Then I moved it to where it lined up with the '500'. This lessend the low end but did not seem to give it more on top. It just ran kind of 'ratty' everywhere.

Eventually settled back to the same original position, right at '0'.

Any ideas?

Yup, the best idea that ever came around....................leave it alone in the stock position. The old powervalve is no where near as adjustable as newer types and is likely to cause more problems playing with it than it's worth. Use a good pipe or porting to adjust the powerband.

I thought the stock position was lined up with the 500 mark and not the 0 mark?

By they way KANE you have the most incredible list of bikes I've ever seen. Your a lucky man. I would love to visit your garage.

I'm a downsized collector. I actually have 29 now but had over 200 a few monthes ago, and over 400 last year before some punk assholes burned my warehouse down. I've been selling out so as to have less to deal with when I eventually move to the mid-US.

How does blocking off the plug help or modify performance.

Ronnie, Nathan told me about your awesome block off Plug.

Thanks for the info!!

that suzuki PV is fuckign useless..... plug it off and have that fucker ported... you'l be happy you did....

[DariusKTM]

If you plug it...then what happens to the engine characteristics?

Same?

[hiperfind]

You know, it's funny, the 'correct setting' is at 500 AND 0....the knob is supposed to line up with 0, but only after a full 360-degree counter-clockwise turn of preload to wind up the PV spring. Follow the manual and you'll be alright. Shit, I don't even know if MINE is OK!
