kzoo,

Check out some of the specialty cam grinders, I can get mine welded and reground for AU$160. to any profile.

I forgot to mention I am installing 37mm inlet and 32mm exhaust valves, + full Akrapovic

Cheers spanner
Not much road riding even though my 04 is plated. I mainly the California desert.

Send Dale Lineaweaver a PM for his pricing and delivery.

Regards,

Joe

RE: Re: RE: Re: LX1 or LX2

Has anyone tried the LX1, and can describe the results?

RE: Re: RE: Re: LX1 or LX2

i have run the top end cam - LX1 - and it just takes an extra 1-2000 revs and gives them at the top. you keep the standard cams midrange and it adds. if you get the lx2 it gives to the midrange and keeps the top end of the standard cam.

the only loss is if you swopped from the lx1 to the lx2 or vice versa.

RE: Re: RE: Re: LX1 or LX2

Thanks for the replies guys, I need to know is there any problem with the valves hitting the piston with the lx1 in the 05 650? The piston comes to the top of the cylinder in the 05.
I am not expecting to much power/ torque increase without increasing compression, that will have to come later.

RE: Re: RE: Re: LX1 or LX2

wrong spanner!

the piston may come to the top but it is concave and the bit in the middle is the same height as tyhe old piston -exactly. so what you've done is increased the compression by squeezing everything into the middle and creating a squish. 100% perfect.

the valves should miss the piston but i would never take it for granted. i couldn't do it. i did one last week and still forced myself to check for peice of mind!!!!

the actual compression WILL go up with the cam. the static compression of course won't. there is a posher name for it....

Yes that is right Taffy, the piston has a dish.
The outer edge, squish comes flush with the deck.
The static compression remains the same regardless of the cam that is used as it is the ratio of swept volume to combustion chamber size.
A longer duration cam will decrease compression as the inlet valve closes later therefore reducing the swept volume by that amount = less compression, except as i understand it, until the gas inertia at RPMs is enough to increase volumetric efficiency more than 100%. This is why long duration cams increase power a high revs at the expense of power at low revs.
Am just trying to find out whether I will have problems with clearance valve to piston I am suspecting not as the lode centre line angle of the lx1 is 106 degrees verses 115 degrees of the 08 cam?
