racer added more weight, and more chain, could that be a factor in a little lower mph?
wee
I don't think so ..He said he was riding it like it was still stock wheel base , sliding the clutch to far ..His 330 times are off , once he gets a handle on this his MPH will go up ..I had the same problem with mine changing from stock wheel base to 62 inches ..... For a short time after going to 62 inches i only ran 5.90s @ 122 very close to what i did at stock wheel base... Seat time and bang 5.70s @ 125 , more seat time and 5.60s @ 126 to 128 ...
Come on now Smokin, the man weighs 205lbs and is 6inches over. We all dont have the natural lightweight build that these bikes perform better with like some people we know  .
Sure weigh has a lot to do with it ..BUT so does seat time ... I know a guy at 200 pounds that runs 9.00 @ 153 on a zx14 and he is getting faster everytime he goes to the track ..I'm just pointing out that his 147 mph is only because it's first time with his bike at a longer wheel base ..He will go faster with seat time ..He was proved he has the skills, just look at how fast he was a stock wheel base ...

Yup hard to go fast with NO air !!! Good part is everyone else is slow in that kind of air ..

Thanks for all the replies guys! Yes I know that I just need to go back and run it some more. The clutch has been acting wierd lately so Im going to pull it and take a look at it. Ill post up some pics of it later. And yes seat time is what it takes to go fast. So hopefully next time out Ill start knocking it down again. Im think that Im also going to try a 43 tooth rear. Does anyone have one that I can borrow for a track day? Ive got a 40 if anyone wants to try it out.
I just thought that If I could ride a short bike that the long bike would be a walk in the park LOL. But Im sure that it will come in time. 1.3x 60's will be my goal then. Im sure once I get that the rest will come.

Also How do you know those busas arent sprayin? We dont see alot of mph difference around here between the two bikes. Somethings not adding up.
A few weeks back my bike ran 9.17 @ 153mph and I weigh 210. The Busa guy aint spraying.
Racer, a good indicator of losing your clutch is drop in mph per pass.
I might add that was 16/44 gears with Schnitz heavy springs and a bad 60ft of like 1.53. Just changed to 16/42 because with the heavy springs right off the line(huge wheelies), cant seem to slip the clutch good enough for 16/44 and I have a 30 shot to use this season. 16/44 had it needing a shift 50 ft from the finish on the button.
Are you running a 180/55 or a 190/50 tire? I will also be spraying a 30 shot as soon as I can learn to ride it on motor ha. I want to get that 8.999 before I start throwing more power at it.

We have the same goal. I really dont want to use nitrous until the motor times bottom out, then spray. Thinking 8.90's on my current set-up(stock shock, 6 over, lowered 2.5 inches, factory seat). I have a 190 Shinko btw. Are you running stock clutch springs? A month ago I tried all 5 stock springs and the 60's were in the 1.40's but I didnt mph over 148. That is why I am putting in the CL lock-up because the launch of the stock springs didnt wheelie me bad. I busted the oil pan slamming down a few weeks ago and could have killed myself. Pan prob fixed but dont need monster wheelies anyway.
If you are running the stock springs a 43 or 44 rear would work great. A 44 on motor will have you at the lights at the top of 5th gear. The 44 lets you launch at 4000 without engine bog that I have found. You have to Speedohealer for either of these gears though or you will more than likely hit the speedlimiter before the lights.

Im running the stock springs with the brocks small spacers, i think they are .180 thick. So if your using a 190 then I should probably add a tooth to what ever you think works good since the 180/55 is taller? Maybe I should try a 44 first. Those sprockets get expensive lol. I have a speedohealer, I just need to install it.
So once you changed out the stock springs you got your mph back up? Let me know how that CL lock-up works for you.

Check the clutch before going to the track again.
I would atleast try to duplicate what you did Saturday before you change gearing.
If your MPH continues to decrease put a new clutch in. Take a stab at it and see where
your MPH sits with a fresh clutch and your current gearing.
How much you want for the 40tooth, as I am still playing around with stock wheelbase times, I want to try the 40t out. LMK I can send some $$ via pay pal.

Ninjaboy runs a 180 mich and after we measured tire heights they were almost even. And yes, once I put the heavy springs in it went back up. I like the heavy springs but have a hard time controlling them with the titanium elbow I got a few years back. I tried a 43 for a while but the 44 just clutched better for me. the clutch life went way up just changing that 1 tooth too. Cant say that I wont go back to the 44 with the stock springs and lockup if the 42 decides to not work with me.

Approximate Measured Circumference:
New Power Race 180, Shinko 190 with 30 passes (pretty new):
Shinko - 77"
Michelin - 79.25"
Approximate Height:
Shinko - 24.51"
Michelin - 25.23"
I was able to bring my launch rpm up 500 rpm due to the taller tire.

I just searched back through the threads and found our actual mounted measurements on used tires. His was 24.5 and mine was 24 even. Shane were these tires mounted when measured?

Yes, those are the mounted measurements.
They should be pretty darn close...your difference of .5" is not too far off of mine. Perhaps tire wear and inflation pressure account for our difference.
There are more details here:

I also have a new 190 Power Race that I will be measuring soon...

Guys don't forget, you really don't need a Speedohealer if you don't want to spend the money for one. There is a speedo sensor mod that you can do for free that will work for the drag racers that want to make sure they aren't hitting the 186 MPH speed limiter before crossing the finish line. Extra gearing makes your speedo read higher than it actually is. I recommend this mod if you have 16-44 or more gearing.
Only downside is that it is a permanent mod, but you can buy a new front sprocket nut for cheap if you ever want to reverse it.

You can file one of the points on the countershaft sprocket nut in order to remove the limiter. I have not done it, but I heard it does the job.

Thats the cheapest way. I always recommend the healer because I would guess that 98% of these rides are streetbikes that dont need to be guessing when they are gonna get a ticket.lol
