OK, first day on a actual track and for the life of me I could not get a good launch. I tried a 5k slow clutch release, 2k drop and go, and even a 5k clutch drop... (NOT A SMART CALL..lol) They all resulted in a pretty crappy hole shot. I am looking for some tips. Thanks in advance...
Oh yea.. its an 01' 600.

On my 98 f3 I would launch at 8000-9000 and just feather the clutch.You will get more comfortable with more seat time.Dumping the clutch isn't going to work for the 600's it doesn't have enough horsepower once it boggs down.

Feather the clutch and roll into the throttle as the clutch catches up to the motor...after that just bang out the gears.
Try and find where the peak torque is on your bike and pretty much start from there.
Dumping the clutch does not win races.

Bike is not stretched. I want to keep it short for cornering. At least it seems like having it stretched would throw off the cornering geometry, I could be wrong about that tho. I definately like the stretched look, but is it worth the cost???

Well I have mine stretched.Its worth to stretch your bike you'll pick up atleast a tenth maybe more.You might want to think about getting a front end strap.You can get them cheap at schnitzracing.com.It's well worth the money.

I youre into weekend warrior racing go with extensions B-U-T, speaking from personal experience they are pretty easy to break,
thats why no companies will warranty them, at least I havnt seen any one who does, the load rating on the 6in extensions I believe
is 250 lbs each, I could be wrong but Im pretty sure, a 900RR weighs 400+lbs, so your extensions will take 500lbs before you exceed
recommended max load, lets say you spread the weight evenly with the bike at a stop, 200 on the front tire 200 on the back your
extensions are taking the brunt of the 200 right where they bolt on, think of the bolt on point as a pivot and the end of the
extension as a lever (you know, where your axle bolt goes through) when you sit on the bike your adding another 75 to 100 lbs or so
to the rear end so now youre maxed or close to the recommended limit of the extensions...now think about it, when you launch off
the line at the track what happens, the combined weight of the bike and the rider shifts to the back tire, combine that with the
torqe of the chain pulling the tire and the torsional forces on the swing arm as the rear squats from the weight shift and the twisting
motion if you slide side to side (not every launch is going to be perfectly straight) and youve doubled, tripled, possibly even
quadrupled the max load of those things and SNAP! Even if you dont race and ride on the street for the look just think of the
punishment they take when you hit a pothole or vibrations from uneven roads and dont even think of riding two up unless youre
looking for a good way to lose the old lady,lol...I ran mine for about three months straight then one day I did a 1st gear burnout for
the boys while leaving the park and everything went fine then all of a sudden the chain sounded like it was skipping on the sprocket,
I looked down and I could see the shadow of my chain damn near dragging the pavement, I pulled over and saw that the extension
had sheared right behind the bolt point and the only thing holding the rearend together was the other extension...I Pulled them off
and sent the swingarm to Thompsons custom cycles http://thompsonscustomcycles.com/ and they welded up my swingarm with 8 in
solid billet extensions and an underbrace for a little over 600 dollars, thats including the shipping, I live in Hawaii and hes in north
carolina so thats about 200 bucks in shipping, they offer an exchange program but he didnt have any 900RR arms at the time, they
said it would take three weeks and three weeks it did, a week of that it was in the mail, you figure about 300 bucks for extensions
or spend the xtra $ for the real thing. Up to you....sorry so long BTW if you do the swingarm choose the V welds theyre much
stronger than a straight weld mine looks exactly like this one but with the stock over brace too...

Oh I forgot to add that unless your really hardcore into the turns you can still have fun with a 6 or 8in stretch they even have a 4in
