Topeka or Bust!!!

[funsizeracing]

I think I ran a 15-48 there last year.

yeah but you weigh 9 pounds (with gear) and can stand on your pegs and not be in the wind... 

[SV88]

So the conscensus is to go down in gearing meaning more top speed right?  But if I'm not running out of gear at 15-45, I'd be inclined to increase torque by going 14-46 Or higher until I rev out at the end of the straight, not the other way.

I gear for corners and focus on not running out of gear.  It's only for a moment that you're at top speed, but there are more than ten turns at Topeka.  You need to drive out of those.  That's where your focus should be.  Sometimes tall gearing works better.  I have a set up for my R6 where I only run second, third, and fourth at Blackhawk as an example.

And the right answer is that 15-45 does NOT work.  I found myself looking for that 7th gear while getting close to the kink.  Really liked the track but I've got a ways to go to figure it all out.  My practice time was essentially eliminated by a leaking outer then inner/water pump leak  (remember the red smoking SV88).  Luckily had some help from Scott Shaffer which completely solved the problem.

Found out that my bike was down on Hp.  If I was riding well, I'd generally catch people approaching or in corners but would get seriously pulled on the straights.  A dyno run b4 the first practice Sunday morning indicated around 66 hp and over 8% CO2 - very rich probably 2 main jet sizes.  To my consternation, found out that very few people are still running 1st gen SV's - could not find two #148 Mikuni jets to save my life.

Should be able to figure all of this out before the racer U May 7th and the next BHF race...

Cheers!!

Steve-It was great to meet you and George!  and I definately felt for you after hearing that you did far more wrenching than racing this weekend.  I'm not sure if we will end up at another race together, but if we do and you need a hand wrenching-just ask.  If I can't help, I'll find someone who can.

I started the weekend with 16-46 and ran a 1:56 in the second session and stayed with that for Saturday.  On Sunday, I used 15-46 and got 3 laps at 1:55 on worn tires during my second race which was LWSB, and that leads me to believe the later is closer to optimal gearing.  I was definately using all of 6th on the front straight on Sunday!

Did you use the dyno that the ASRA was using?  If so, 66 is pretty good.  I got 62.4, and Becka(pink, #410) got 64.4.

Jack - Likewise it was good meeting you.  Wrenching thru mechanicals builds character however my goal is to first have a reliable machine so that I can concentrate on racing.  I added 15% to the Factory dyno (ASRA) number of 57 and you should do the same so you were probably in the neighboorhood of 75 Hp.  I'm going to concentrate on getting the jetting right b4 having the motor freshened up after BHF (will not do MAM so I'll have 3-4 weeks).  Will work on my R6 prepping it for sale.

Steve.

Yeah, that is a Factory Pro eddy current dyno, and it's numbers aren't really relevant to Dynojet numbers.  I'd say Jack is pretty much spot on.  I've heard 13% to 15% difference.

WOW 1:55- 1:56 That is smoking fast! I was pretty happy with high 2:02 in my last race, but it wasn't enough for the AM win. Hopfully I'll have some more next time now that I know the track a bit.

[Court Jester]

the best i could get was 2:00 flat. and that was with pushing the front in sliding the rear in several turns. i have no clue how some of those guys are knocking out 1:40 somethings.

Maybe your tires were shot or something..??  I was hovering 1:50s all weekend and was barely spinning the rear and the front was rock solid even after 5 sprints on the same tire..

Consistent 52's with the SV.  Forks are stock, and they were limiting.  It's gonna be a cool bike.
