What size domes?????
I just happen to have a Yamaha/Westcoast head with replaceable domes sitting around doing nothing.
I am thinking about putting it on my Blaster that I am getting on Friday.
Engine is a 61X
What size domes should I use on a stock non-ported engine for a little more power?
Keep in mind that this head uses the stock head gasket.
Not sure where I want the cranking PSI to be with this one. I know I don't want it near my other one at 195.
Do I want around 175?
Factory Pipe Limited
Factory Pipe Water Box
Solas (at this time, unknown pitch)
I think this is all, old age kicking in again.

175-180 is a good pump gas safe range ....185 IMO is pushing it ...but stafe as long as you keep it cool with 93. I would MANDATE on my skis with factory pipes...dual cooling however....I never ran without it.....with my MOD pipes

So how does this sound?
That should be a safe combo, correct?
