I am going to be rebuilding my engine very soon. I need to know if I can run pump gas on a 12.5:1 piston? What cams are best? Can anyone recommend someone who does good head work? Best cluch springs? How much do you think this will cost me with and without labor? Thanks in advance.

 

i got a 12.5 piston, web 109 grind cams, all the goodies for the valve trian, and clutch springs form tvi for a little over 1000 bucks, i know they have a race head for like 2000 bucks (i think), i dont know about running pump gas with the piston, im running methanol in mine

 

No you cannot run pump gas with 12:5:1 ratio. I believe you'll have to run atleast 100 Octian.

Anyone else out there have any advice for me I would really like to have alot of options so I can get the right set up for my quad... Thanks.

 

Whats the highest you can run with pump gas??? I want a piston also but $$ is the biggest part.. [img]i/expressions/face-icon-small-sad.gif[/img]

 

I think the 11.5:1 piston you can run on 92 octane.... I dunno any others that you can still run on pump gas.

 

Depending on what kind of cam you're running I'd have to agree with saying 11.5:1

 

Bom if your doing the work yourself i would also get a set of bolts that go to the cam carrier, i broke one but got lucky that i was able to get it out of the head

 

Thanks for the advice... I am still debating on weather I should do it myself or have someone else do it for me it depends on whether I have time when I get the parts.Thanks again.[img]i/expressions/face-icon-small-smile.gif[/img]
