Look into the specs on an EV 13. It is designed to grab the cats ***** at a lower rpm. Got one in my 80 CI & nothin' around here passes my except suicide jockeys on their zoom splats!
Hatch.

 

I think I agree. Could very well be detonation. You need a different cam too.

 

damn camshafts..... alright, anyone got any suggestions? .... should i put the EV27 back in there with the kind of compression the heads and cylinders measured out at? (9.8:1)

hope to hear from you guys!

 

Sell your 3010 and your ev27 and buy a 3020, that's a beast of a bolt in camshaft. Espically with the compression you currrently have , chad

 

thanks chad!... considering the specs, i was thinking it would work well

even considered the 'crane fireball 310' at 236 and 242 durations, respectively

 

Id stay away from those crane cams, I just tend to stay with what I personally know works, and 80/80 is easily achievable with that cam,

 

i hear yah, chad

but i gotta come in early with some torque.... i live in the city and i gotta pull away from traffic and hop yellow lights when it demands .....i can't wait until i'm up at 3000 or so before it pulls strong

 

dong get caught up in the whole idea rpm range, that 3020 will make 70 ft lbs by 2k, it wont be soft, espicially with 10 to 1 with a lighter bike, if its soft, ill buy that cam from you for full price, thats how sure i am of those camshafts, im a huge advocate of vthunder and you wont be disppointed.

 

alright, you've convinced me .... i'm gonna get the 3020 and will give you an update once i run it after install

thanks for your advice and help, chad!... i'll keep you posted!
