The bike is injected. 2001 with the M&M injection. To my knowledge the heads are (or were) the same on the A & B motors.

You're on the right track thinking about the HQ0039s. They open fast and close gently (quietly). They seem to work good at any comp from 9.5 to 10.5. Check out the charts on their site!

I've done tons of reading and comparing and I'm no closer than I was two weeks ago. Where I'm getting hung up is on the power output of these cams. Most of the .510 cams are barely making 100/100.  I'd like to think my heads alone would get me close to those numbers with my existing  82 HP./94 TQ. and 203's. Am I wrong? Anything bigger than the .510's and I'm moving the power up the RPM range. I don't necessarily need the power right off of idle but I'd like it fairly close (around 2k). Once the bike is moving how much power do you need to keep it moving? The .570's seem to be very popular but I'm not certain where the power band starts. Gear drive is by far the best way to go but this is not my Hot Rod. I have a 124 in a rigid that runs decent for when I need to get my torque thrills. If that doesn't do it the Busa will cure all my speed needs. So I'm after a nice ridable bagger with a little extra power. Chain drive cams and a set of replacement shoes will do what I need.

When you first suggested these I thought they would be to big. Now I'm having second thoughts. My TW60's were more of a top end cam but they made the power low also. They made 90 TQ @ 2000 RPM with a peak of 105.8 @ 4250 and peak HP of 104.8 at 5750 RPM. The peak HP with TW60's is too high for this application but I wonder where the 55's work?

Maximum lift doesn't effect the rpm range (or very little).
Look at the Wood TW6 and TW6H, both have the same rpm range. But the H has high lift.

BTW, the M&M injection will probably keep te numbers low.
Do you want the keep the injection? If not, switching to carb on a M&M bike is quite easy.

TQ MONSTER I would have to agree with you. I would also look at the S&S 585 cams or even the 625 cams for a 95. Hook it up with a good set of heads 10.5 to 1 compression and either a CV44 or a S&S "G" with a Thunder Jet. Then you have a menu for some H/P.

My 95 spun the rear wheel at 110 and it was wet sumping at the time. With the problem corrected I can feel it has a bunch more power now. I just need to get it on the tread mill again.

I will be keeping the injection. Again this is not my Hot Rod bike. I'm after a set of cams to compliment my heads with a relatively early entry to the power curve. (I think) What determines where the power curve works?

PUZZLED there are a few things you need to look at. It all has to with valve timing. Valve opening and closing, overlap, and duration. The first thing to look at is your duration. The higher the duration the higher the rpm curve (as far as power) and the more compression you MUST have. Unless you have a turbo or supercharger. These 2 items you will run lower compression and set the boost on the device which will determine you your final compression. If you want a lower power curve look for early valve opening and closings and a lower duration. If you add lift you will increase your power but not your power curve.

That is exactly what I was after. Thank you.
