I am ready for warm weather and some riding. just wandering what my bike will run like this year, rebuilt over the winter(first time). stock 80 evo flywheels and rods;kb 9.5/1 forged pistons,heads ported/polished and shaved 50 thou (if the math is right, takes it to 10.25/1) sifton oil pump,andrews ev59 cam, SE billit lifter blocks, quickie push rods, S&S beehive 650 lift valve springs, S&S super E, V&H straight shots (uncorked w/torque cones), new HD lifters, ultima single fire ign. . heat cycled and waiting for snow to melt, just wandering if anyone had any toughts? thanks

 

I think your math is off a bit in order to properly estimate your compression ratio you need to know your bore size "did you bore it" deck height head gasket thickness and cc's of your heads
just guessing with your cam and pistons and guessing a 0 deck height and stock bore and using .030 gaskets and taking .050 off the heads usually drops your cc's down to around 68-72cc that would put you into the have to use race fuel class at 11.02:1 static and 9.8:1 corrected compression.
and I could be totally wrong. without all the numbers its just a guess


check your cold cranking pressure you should be around 189psi with your setup if your over that your going to have to use additives to bring your octane up.

 

Where's the pics of this beast ?

 

Thanks , I will check the comp.

 

 

Yea, plus 1 to D, need specifics to determine properly figure your ratio.. and if your ccp is over 205 that will put you up in the 11:1 range..

 

Sure is a purdy scooter.
