Help with cool head


Recommended Posts

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.

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

 

There are a couple of other questions that need to be answered before you get the correct answer to your question.

Need to know what bore, and what altitude your at. Give us a call tomorrow and we can help with all your needs.
