Help with cool head

[dj_diablo54]

Ok so I am going to buy a NOS cool head, but have a few questions about the domes I should get, I only have kn filter, T5 pipes and jetted. What size should I get, I am going to get some rees as well then see how the bike runs and continue to add

It all depends on your elevation and fuel octane, Noss's website has a chart at the bottom of the page. If you still aren't sure just e-mail them and they will recommend the best domes for your particular setup.

Just F.Y.I. I went with the 20cc domes due to a conversation I had with a fello BHQ'er he said that the stock cranks can't handle to high of compression enless they are trued and welded, don't know how much truth is in that but I am not one to find out things the hard way, 20cc domes put me at 158psi a side at 1100 ft and that was a bit higher than the chart

I ran my banshee at 155 psi with timing set at +4 deg on 91 octane fuel on a non welded crank. If your going to be running straight race fuel and have a compression of 185 then I would highly recomend welding the crank.

 

Yea if you want to pull the crank out and have it tured and welded it is good to do but not a must.
