why are the Hot Seat and ESBS "billet" cylinders so much more durable vs a bored and nicasil'd cylinder like HPD or AAEN? and what do they cost?

 

Cylinder wall thickness. The billet cylinders also have improved cooling capacity over a stock cylinder. The billet cylinders also have better ring seal due to lack of distortion under load. The stock ported cylinders have proven to be very reliable, with higher than normal cylinder pressure with high compression pistons or power adders I would opt for a billet cylinder, just a little added security.

 

any costs?? since you have the ESBS one i'm sure, what are they asking for them?

 

To be honest I am not sure of the price, I would guess in the $300.00 range. Reguardless of
which company you use, it will be money well spent in the long run.

 

sp700...i called sbs and talked to roger. he said they dont do a billet bore 580. from what he explained is they rebore the stoke and then put a steal sleeve in it. is yours custom?

 

Call Gary and talk to him, yes it is custom made, he has the program for the cnc. He has done a few of them. But the base 580 kit does not come with a billet cylinder.

 

Anone have the Hot Seat 600cc ???
