I went with a Two Bros full system on a 98, oval Ti one can and an dyno jet stage two kit with a K&N filter with great sucess. I got Two Bros and Dyno Jet on a conference call and told them what I wanted and they worked it out for me together. Drilled the slides changed the jets (careful those bad boys are soft brass) and set the needles (I think at three) one thing that no one mentioned is that on inline 4's the middle two carbs should be jetted differently or at least I've found several shops or people in the know tell me this. 37,000 miles later I've never had a problem and have not yet change it. One thing it did was drop about 50 lbs off the bike by removing the center stand (had to) and the twin OEM pipes and headers. That was worth a few HP right there. I never dynoed it.

Hi, What did you use for the split shims in your stack ? .1 s ? What O.D Thanks Herb I used a 0.05" thick X 0.512" dia (prolly considered a 0.51 but thats what notes said.) No, thank you for the opportunity to share. -D Isn't .05 inches equal to over 1mm ? Are you sure that was not .05 mm ? I think 1mm is is huge for a splitter ? I am i missing somethin here ? I was planning on using a .1 mm by 20 mm to create a 2 stage stack in my shock . Thanks herb Ah yes thanks! My notes are wrong. I used a 0.005" thick shim. Thanks!

This may be a little off topic but I think Dynomometer may be the latin word for inaccurate. I say this because the manufactures of dynos argue insesently about all the different ways "theirs work better" and the ASTM has 4 different standards for dyno corrections factors for engine dynos. As we all know the mags come up with some seriously different numbers (for many reasons) and even in my little town of 700,000 we got 4 dyno's and all 4 would give me a different number beyond a 10% margin of error. Do they lie? I say not really. Do they tell you the truth? I say not really. So what do they tell you? I think they do give you some information that is useful in helping you tweak your bike. A baseline if you will. But they are a bit like testing your internet connection speed. Ping a different test site and get a different speed. They are different for so many reasons. my 2 cents. I used a dyno to check an old gixxer I had. I put a $1000 pipe on it and the same dyhno told me I got 3 hp out of it. I went to another and poof! I got 25hp gain!!! Which graph do you think I showed folks?

Hey all! (my first post on here) I did the whole show on my 98 xx. Springs, compression and rebound valves. Since I change fork oil every other year the bushings and seals were still in good shape. I'm a fairly agressive rider and a big boy too and went with a 1.00 set of springs. Having been a graduate of Paul Thedes Suspension Seminars I went ahead and used a three stage shim stack on my compression valve. I did this in an effort to gain some low, med, and high speed damping on otherwise unadjustable forks. I used 10 shims in a 5,3,2 stack that worked out perfect for my riding. I use 25mm of sag and put an Ohlins on the rear to balance the system. On some twisties where a couple of my 600cc friends would walk away from me in the real tight stuff I found a lot more feedback and compliance in the suspension and the 600's as new and light as they were did not get away with the wheels sticking to the gound like they did. The suspension of the XX is it's only flaw in my book. I had to make a change.
