What has a mono block head and 150hp, well a 2-stoke thats not running.

 

thats a 84 model
its held up real well
any performance tips

 

Wow I need to change reeds in the ZRT then.

 

Time for a Merc Black Max or a Pro 2.5!!

 

we have forged Weisco pistons 20 over top pinned lightened balenced
on the way
how much should I take off the head for about 130 psi?

 

I was gonna guess a Honda Civic.....

 

it is a black max 2.0
a 2.5 would rock

 

Eww. Not sure about that. Just be sure to calculate squish clearance. Wonder if it would be a good idea to set those heads up for o-rings... Ive got a Kawi Ultra 150 I threw some ADA heads on with 42cc domes and compression jumped to 140-150psi per jug.

 

Hemi woulda been better
naw cant put down a Merc like that

 

I think well take off 10 thou at a time until we get it right
These are some badass engines needlebearings everywhere
