Even in straight line if you do it right the tires will just start spinning for a good 2krpms before it catches.

If that is the case, something is wrong. Either you're on extremely hard touring rubber that is unsuitable for any kind of performance riding, or perhaps you've got some very poor suspension settings/problems. There is just no reason that the symptoms you describe should ever happen on that particular bike. The F2 was good for ~74 horsepower at the rear wheel in stock form, low 80's jetted and piped. My 02 R6 is putting down ~110 at the rear wheel, jetted, piped, and dyno tuned, and there is no way I'm going to be able spin up the rear in a straight line through throttle inputs. My previous bike had similar power output to an F2, and even being a twin I did not have any real issues with slides, but I always ran appropriately sticky rubber. To experience some of the symptoms you describe on that particular bike one would have to be TRYING to crash.

Yes I think the rubber I'm on is what is causing it. The rear end has Bridgestone Battlax BT54s which from further searching are classified as a sport/touring tire. So yea, its kinda crap but I do like the tread life. I really don't want to replace it until I need to and there is still at least another 4k miles of life left on them. As for now with the weather being a bit colder ill just leave it on until next season.

So yea I think you are right about the rubber. After reading some reviews about other people switching to stickier tires from the BT54s they say it made a huge difference.

That's some incredible gain right there, are you sure it's just jetted and slip on exhaust and dyno tuned? How much weight did it lose? What sort of jetting (stage 1, 2, 3, etc) and dyno tune was it? Any of the sprockets regeared? That is 05 ZX-6R territory. The 01-02 R6s didn't even make 100 rwhp stock, 01 GSXR600 was the first to break that 100 limit.

How about fuel efficiency, does it burn noticeably more gas?

I agree, it shouldn't spin up straightline, I was never able to spin up the F4 pinning it hard on 1st or 2nd.

I purchased the bike at the beginning of this season. It was a WERA racers backup bike. It has a full M4 titanium system (header, mid pipe, and slip on), jetting and dyno tuning was done in house by his team (therefore I don't know the particulars), 520 chain conversion with aluminum vortex sprockets (deviation from stock I don't know yet, havn't needed a sprocket change up until recently), Traxxion Dynamics front fork rebuild, Ohlins triple adjustable rear shock, a Sprint damper, Woodcraft rearsets, and Vesrah RJL sintered pads. That is all the modification I'm aware of.

The previous owner showed me the dyno sheet, but I do not have a copy of it. From what I have seen firsthand on the track, the bike pulls unusually strong for a 600. I have not yet been in a drag race scenario with a 636, but I have been able to pull on just about all of the 600's to some degree that I have come across.

Since I purchased the bike during the season I havn't had any downtime to pull the bike apart. Over the winter I plan to have the suspension sorted and it will be back on a dyno here in a few weeks so I can see firsthand just whats been done. It appears to have been extremely aggressively tuned as it drinks gas like koolaid, rejects everything but 93+, and misses/backfires on occasion under street conditions.

It's important to keep in mind that there are more important things than peak power output when talking about engine performance, though. How broad the engines curves are, where the peak power lies, and how quickly it can gain and lose revs are what make or break it. That's one of the reasons you'll see big leaps in performance in some bikes over others without big leaps in peak power figures.

I'll post a copy of the dyno sheet in a few weeks when I get it done.

Have you guys seen that video of the camera behind the windscreen on a 330 hp turbo Hayabusa?

If not, I'll try to find it again. It's spooky.

Hey Deal, reading about it just made me drool. The mods didn't sound like something you'd find in an amateur's race-prepped bike. I don't mean the quality of the parts, but the combinations that were used. I'd love to ride something like that, if not for power, but for the handling traits at least.

How much did you shell out for it if you don't mind me asking? What was the mileage when you got it, and how much was it used even as a backup bike?

Sounds like you have a good bike. I am aware that R6 is a revvy bike, light flywheel.

When you're sorting out suspension, are you going for a rebuild or a track set up?

It's been a great bike for me so far. I talked the owner down to $5000.00, and the bike had 3600 miles on it, mostly street miles from before it was converted. He switched to a ZX-10 as his primary race bike, so he wanted to get rid of the 600's quickly.

The suspension setup is completely unchanged since I purchased it, and I need to set the sag and get a baseline setup for my weight and preferences. Switching from my old Ducati to this was a major learning experience, so I wanted to wait until I was very familiar with the nuances of the bike before I started trying to make setup compensations. It's not too far off from what I want, and I think setting the sag will bring it to 90% of where I want it to be.

Now if I could just learn how to ride it to its potential I'd be in good shape!

Eek!

OK...
