Hope I wasn't one of "those guys" Haha, like I was passing you Rick!! The corners that scrubbed my speed off the most were 6,9,12 I had to downshift to 1st on those which was a pita because my gearing was too low for 1st, the front wheel tends to leave the ground enough that I needed to straighten it out before piling on.. I'm looking forward to trying the track again with my bike running properly!

I liked the 10-11-12 combo, was able to be on the pipe through most of it in 3rd. Most difficult for me was turn 6, 2nd gear rpms too high, (to my sympathetic ear) 3rd gear rpms too low to really manage it. What are you running for gearing? I have 15/47 and was never in 3rd through the infield.

15-46 The h2/h1 pipes only make power at 6.5k tho. I need more low end grunt. Maybe put on the wirges I have?

Piston port... Not surprised! You were in 2nd gear then, not 3rd.

Your comments have me thinking. (oh, oh... ) I find it interesting that my h2 REALY pulls HARD around 6.5k and well beyond, now that I have velocity stacks instead of pods. Prior to the stacks, it ran out of steam on long straights right around redline. The jetting hasn't been altered. The plugs are a nice tan colour. The downside is a lack of grunt at mid to low rpm's. It's even tougher to start when cold or even cool. Hot, it fires right up. Velocity stacks were the ONLY change. To keep it on the boil, I shifted down as low as 1st gear to keep the rpm's up on the slowest corners. I can't remember my gearing. I'll have to check. It's been suggested that the reason for lower rpm power drop (and starting issues?) is a lack of vacuum due to the stacks. Thots on any of these issues?

It sounds like you are a bit lean with the velocity stacks on part throttle, I could notice a definite difference in cold starting when I finally got my part throttle jetting dialled in, I need a good bit of choke now unlike before it was optional... But if you lose power after putting on the stacks, that would be my first thought that you are now too lean... You may have had the same flow issues I had with UNI's last year.. As soon as I took the filters off it reved out fine but I needed to re-jet to take advantage.. I now know if you don't have flow, it doesn't matter what you do with jetting, it's just going to be choked out.

If I recall, you played with the needles... is that right? Did you change the pilot/idle jet as well? Sounds fair. If I have time this Fall, I'll have a go at some changes.

I need a close ratio transmission, got any of those?

He's talking about his H2 pipes on his 500...they are very similar to my Clough 500 pipes, shape wise... Mine hit at 7k and rev well beyond "my" useful range as I'm good with a max hp around 10k.
The 500 torque pipes started hitting around 5.5k but again, 7k was when it was at full boil, the power started to plateau at 8.5k but would rev out to 10k still.

The velocity stacks change the effective intake length, so they effect at a certain small RPM range. It does make it a bit difficult to tune.
And Andrew, half the fun is having the front wheel leave the ground while leaned over, it's cool! Just gas it when you about at half of what you were leaned over in the corner, she comes up and straightens out at the same time........

I used to ice race with a talented guy, he'd have his left foot on the peg by the time he hit the apex and would power his CR500 out of the corner on the rear wheel while still crossed up... He claimed 2 things about that technique, he got better traction and I was a pussy for not trying it! I think he forgot about the talent portion of the maneuver! Lmao!

The 2-3-4-5 combo is still going through my head... Do I have issues?
