2004 RC51 power problem?

Hello everyone, I recently purchased a 04 RC51 upgrading from a 97 600 GSXR SRAD. Obviously I was blown away from the power but I think I might have a problem.

I have a buddy that I ride with who has a 99 VTR1000. Basically the more street friendly version of our bike which puts out a decent amount of less power. However when we race (not on the track we have long bridges out in the middle of no where) He seems to be toasting me!

He can do these straight up power wheelies right off the line not using clutch at all. I can't do them at all.

Also he sticks with or pulls on me through all gears until like 165 when I finally just have more top end them him.

We switched bikes to see if it was a rider issue and it wasn't. Both bikes are 100% stock.

Any thoughts? My bike has 11k on it and as far as I know it hasn't been tuned in those 11k. My sprocket looks good. Chain is tight. Any advice would be greatly appreciated. Thanks

PS. The person who owned the bike before me passed away. I can't really dig any info.

Howard Frankland or Gandy? lol

The bikes have the same size engine and his has better gearing for what you are doing.

I would have the bike placed on a dyno and see if it is where it should be, maybe he got one of those factory freaks?

The fuel injection on our bikes was never dialed in perfectly, a PCIII helps a lot with that.

Have you checked the air filter? Without having someone actually check the bike out, all you will get is guesses.

Frankland around to Gandy obviously! I suppose you are correct. seeing that you are in the area do you have any recommendations on which shop has decent pricing for dyno runs?

Well stock for stock the numbers are close.

1/4 the rc51 is 6/10th quicker
Top speed the 51 is 10 mph faster
60-80 and 80-100 its a different story. Vtr is much quicker.

Drop a tooth in the front sprocket or go up 2 teeth in the rear. You will see a considerable difference. Very cheap easy to do mod and very well worth it. I run 15/40 and am pleased with the setup.

I also run a 15/40 setup with mine but on top of that I would suggest getting a pcIII and a good after market exhaust. Also, I would do a basic sweep using the service manual on what you should replace/clean including air filters, plugs etc. or you could take it to a shop to get a tune up.

OR

Maybe it's because the bike has so little miles on it

Most in the area swear by Dynoworks in Sarasota (http://www.dynoworks.com/).

RC51's are slow turds... They are 440lbs with roughly 120 rear wheel horsepower, the lower horsepower Superhawk actually has a better power to weight ratio and even more so with an open race exhaust which not only lets it perform better, but loses additional weight.

The downside is that the Superhawk handles like shit. Just putting a set of race slicks on one is an instant recipe for disaster as the frame does not cope well with the extra grip from the stickier tires. Even with thousands of dollars in Ohlins suspension the Superhawk just never settles in on a racetrack.

The RC51 on the other hand truly has a purpose built frame that can take anything you throw at it and when you do mod the suspension with quality bits. It becomes extremely planted and controllable even if not nimble due to its weight.
