Does any body know how much power a cool head would give my quadracer?

low end?
mid rang?
top end?

 

you will get alot of power from the coolhead becasue it increasis the compression if you run diff domes and also gives alot better cooling to give you longer preformace + theres no gastkets and more just O-Rings. The cool head has a closer squis band on the clyinder as well so it gives the bike overall much better preformance.

 

I actually just bought a cool head for my 88lt250r,i havent installed it yet,but the design alone looks much better than a stock head. On my dome the top uses oring but is looks the bottom uses a head gasket, because there is no indent for an oring.

 

let me know when you get it installed jmoney, and tell me how you like it thanks.[img]i/expressions/face-icon-small-smile.gif[/img]

 

LT 250r dont really have cooling problems like the 500 but if you got the money they do look trick. However id mill the head for 45 bucks and use the rest to buy a bigger carb or a hooker.

 

hey Jmoney, get your cool head installed yet?

 

i got a cool head but i never drove it w/ stock head so iwouldnt know how much power it adds . all i know is it will make a 250 fu!@$%* fast![img]i/expressions/face-icon-small-happy.gif[/img]

 

I believe (not positive) that the coolhead uses a gasket stock and that the o-ring coolhead is optional.

I had the head milled .020" on my 86 for 26$ not including a new head gasket. It added more power than a pipe and I’ve been running on 89 octane pump gas for almost 6 months now with no problem. I'm thinking about having it shaved .010" more to see what happens. Could always go up to 93 octane if necessary.
