Cams in Gen II

[Abusive]

What's a good cam combo for a GEN II with stock bore. With and without headwork? Counting coins and dont want to make a mistake!

[PetriK]

Propably depends on target use - stock engine with cams only vs 1441cc higher compression for strip and street.

E.g. my 240+hp 1441cc gen2 engine is built by Bryan Snyder (bryansnyder@att.net) and head is from Jim (Y2K). Fairly decent head, cams, and other parts combo.

Strip and street mostly strip!

Yoshimura has just released a Stage 1 cam for GEN II Hayabusa/B-King.
Intake:   9,5mm TRUE lift ( lift at the valve. If you measure the cam itself it will show 9,7mm lobe ) 249 degree duration
Exhaust 8,7mm 235 degree duration.

I dont know the price yet but I am sure they are expensive.
These are made as a "drop in" even with stock exhaust.

Bryan what hp will that combo make? Where would you degree the cams in? Also that would be on mrx01 or q16.

[BRYAN]

I don't really know what horsepower just the cams would make. I have always done some other work to the engine when installing cams. Piston to valve clearance will dictate your cam timing. Make sure you check it. I would guess 205-210 with just cams and good fuel.

An that would be better than 385 megacycles? Wanting to do 1440 bore, cp pistons some head work with a good street cam setup.

Brock's IN031 with EX041(basically a pair of .385s),Competition CNC head, in a 1441 was good for 218 hp on Brock's Dyno. The customer has been 162 in the quarter. Nice streetbike.

I have never installed a pair of .385s in a stock bore busa.

My 1471 has 385 cams, low compression ( around 12-1 ) and a hand portet head.   225 RWHP.

 Brock's 385 IN031 and stock intake on the exhaust will be very nice.
