Need advice on some engine work

[reconstyle85]

2 weeks is very good.  Keep me posted, I am curious to see where you end up.  I am constructing a flow bench for my little project at the moment, but the milling of the heads is in process.  I am going to get the slotted cam sprockets from ape, they are $49 brand new and I have some stuff to order from them anyway.

Man, I wish I could learn how to do all this stuff myself... :(

I'll post up when I get the head and cylinders back and let you guys know how everything turned out.

Good luck man!

HOLY $h!t!!!! There's some money in that machine!

It's hard to believe that it only makes 155rwhp, not saying that's bad, but I guess after the 140ish mark you pay big bucks for every hp after that.

So realistically, do you think I'll be able to hit my goal of hp in the mid 140's with just 11:1 1216 kit, port/polish and mill? gsxr cams with slotted sprockets,  with the stock carbs?

My Bandit made 145 rwhp with the Holeshot 1216 kit, lazer ported head and the 38 mm carbs. So yes, you should make 140's.

Hey B, your dyno sheet shows your torque peak is lower than I expected.  I assume you did that with your cam timing?  Have you experimented with that and if so what worked best for you?

The dyno was done with 98 GSXR cams set at 103 intake/106 exhaust. I have set them at 106/106, but thought it hurt my 60 ft time a little, but with a 1 or 2 mph increase in the 1/4 mile.

103-105 seems to be popular as does 104-106.  I have not yet done any cam degree work on a b-12.  What would straight up or stock timing be in degrees for reference.

I believe that it is 108 on the intake and 105.5 on the exhaust. Those numbers are from  memory, so they could be wrong
