I have started modifying my bike getting her ready for a run, we have shaved the head and added some high compression pistons, valves, springs and rings.  This is just the beginning.

Fair warning -- I started out in LSR on a 2000 ZX12.  The bike was fun, I got a record here and there, I got a hat or two, and I got addicted to this avocation.  Oh, yeah, I also ruined my plans for a wealthy forever by spending most of the retirement money for the bike, the records, the hats, and so on.  Welcome to the group.

Take that head, just over the state line into N.J.,to Bob Carpenter. He will fix you up with cam and port work to make some big horsepower. Where are you going to run it?

Fred speaks sooth, Chillin.  As a target -- you'll need a minimum of 200 hp to see 200 mph on a timing slip.  More, of course, is better, but might be hard to do at stock displacement.

Hey Slim,
What should a guy expect for tire spin at 175mph approx?Percentage wise? and how much ballast do you think the salt needs if everything is good? I would imagine final gear ratio is a trade secret. But if not? what do you recommend.Thanks (a new guy to salt).

Hunh?  Secret?  Unh, you're new here, aren't you?  There are very few "secrets" in this game -- most everyone will be very willing to help you.  Try this:  stock front sprocket and maybe 15% smaller rear -- to start.  Take a handful of sprockets and keep fiddlin'.  I think the 12R started with a 46 rear and we arrived at Bville with a 42 and quickly went down to 40.  We've played with 'em all, down to 36.  I think there's a 38 on there now, but we are spraying it (well, we would if we ever got the bike running cry).

As for tire spin - hey, I don't know how much there is/was, but I know that when we added about 50# to the swing arm we picked up 7 mph. YMMV, of course.

Marty and Chill, gear your bikes for the speed you plan to go... in 5th gear, about 300 to 500 RPM below your redline.  There are multiple calculators to help you do that.  Bring front sprockets +/- 1 and rear sprockets +/- 2, that will help you sort out what your bike will do.  If you are running the salt, figure on about 7% slip, bring or add plenty of bolt on weight or you will see north of 14%. As they say YMMV
See ya on the salt  cool

Yes I'm new so please excuse the next question if it seems stupid.  Can you break a Bonneville record somewhere other then Bonneville and submit proof to have it registered?  I will wait for the WTF's to roll in.. shocked

Bonneville records are set at Bonneville. There are several different sanctioning bodies that run events at Bonneville and some of them sanction events at other venues. Any records set at those venues are records for those venues. For a recognized world record the speed is normally recognized by either the FIA or the FIM depending on the vehicle.

It is possible that you could set an FIM record at another venue, say Australia, and it would eclipse an older record set at B'ville.

Dodge!!  Calm down now, just asking.  We have a real nice international track up north in Minnesota.  I'm going to be running there first to see where I stand, of course that is asphalt and Bonneville is salt soooo.... Not exactly a direct parallel.
