Round two completed today.  I was able to lower my lap times by 4 seconds over the weekend.  I was quite happy with this.  Did much better in the novice race passing some people and only getting passed by a few, most bikes in this class are inline 600's. 

In the Ducati cup I was once again crushed into the ground by the other bikes all at the 118hp limit, mine was dynoed today a the track: 66hp coincidentally my race number.  My bike tops out half way down the straight at 210kph while the big bikes, even stock 748's can easily reach 260kph with the 998 and 749R's reaching close to 300kph.  Fun none the less and trying to chase these guys down is making me smoother and faster. 

I went from a HJC AC-12 to a Suomy Spec R-1 and can't believe the difference.  Sooooooooo much better!

Here are some pics:

I think the helemt adds about 10hp overall.   [laugh]

Hi, I got a few questions.
Did you change springs in the fork?
How much of  the fork legs are above the triple clamp?
Did you raise the rear?
Stock rear shock?
Have 749-forks on my 900ie but i am not sure how much to raise the
fork legs in the triple, and raise the rear to get proper geometry.
Did not measure before changing  :-\

You want to get about 11 degrees of swingarm angle if you are setting this up for the track. So, raise the rear end to achieve this. Your forks are not the same length as the stock forks so your reference of "how far above the triple" won't matter. Yours are longer. To get the front end right, it's a bit of trial and error. As a starting point, the stock forks usually work good with 10mm above the stock top clamp. If you want to measure your forks against the stock ones and just figure out how much that is, you can start there.
Also, getting the forks and shock sprung for your weight is a must...again, I'm assuming that you want to know for track riding purposes.

Is that with the rider on the bike? How do you measure? Is zero degrees stock?

4 seconds - that's a lot - must feel GREAT [moto]

Do you find the Suomy to be quiet? My Schuberth R1 is not, and Suomy + AGV GP Tech are two of very few
helmets in my size 3XL. Round or oval head shape?

Thanks Faster, and you are right its for the track.
The reason is that i lowsided in a corner, and cant figure out what I did wrong.
Probably my mistake but the confidence for the bike is bit hurt :-[
So I want to be sure that the setup isnt way wrong.
I'll try to measure the swing angle and go from there. [thumbsup]

That's for a dual sided swingarm. Measure with the bike upright, both wheels on the ground (level surface), and the bike unladen. You will need two people, one to hold the bars and one to measure. Or, go to Home Depot, get an angle finder for approx. $10 and you can measure it with ease.
Put the angle finder on the top of the swingarm. Raise the rear end with your hands as high as you can, then let it settle. Take a reading. Then push down on the rear end with a lot of force and let it settle back up slowly, take another reading. Average these two reading and that's your swingarm angle. This method is what I do to take into account the stiction of the shock, and give you a true measurement. It's the same thing you do to measure sag.

I've had a lot of success racing a Monster and race with several others. I know about setting these up. If you are even close to stock, then you are trying to corner a chopper...they are just not set up to corner. You can do trackdays on them (as you see lots of people on here post pictures of), but as soon as you start riding faster, you will ride beyond the capabilities of your suspension and street geometry and crash. These are not like a middleweight that's designed to ride hard "out of the box". You can do it, but it takes some work.

It's critical to get the suspension and geometry right. I don't know what happened to you but did you feel anything before the crash that was not right while cornering? Have you tried to baseline your set up at all? You will have to get the forks and shock sprung correctly for your weight first thing. Then have a suspension guy baseline it for you, or read up on it and have two buddies assist you.

1. get your suspension sprung correctly
2. set your sag, and rebound
3. set the swingarm angle and fork height
4. ride the bike, and make small adjustments

Have not got the shock or forks sprung for my weight.
Guess there is no way  around that.
I believe the fork spring are a bit hard.
Front: 749s forks ca.40mm above the triple
Sag with me on it: 34mm

Rear: stock sachs, sag with me on it:20mm (rideheight raised about 10-15mm, no exact measurement though) 
Have tried to set it up as good as i can.
Feels pretty OK, but I have nothing to compare with.

Have read some articles about suspension.
There are a bit different opinions about sag (how much one should have)
Have not find out exactly the sag numbers for monsters.

Am I somewhere near the correct settings you believe?
Or should I just drop the bike in the nearest lake ;D
