First-time drag racer

[Guest]

Thanks to some forum members (thanks in particular Greg B!) finally got my hands on a GS-powered drag bike.

I'm a long-time motorcycle road and MX racer (the story of my GS1000-powered road racer is here), with a few endurance, flat-track, and cross-country races thrown in for good measure. I've never drag-raced, though, but am looking forward to it.

I'm sure I'll have lots of questions; any advice/thoughts/recommendations appreciated!

Welcome. A few racers here will be particularly good resources for you (stetracer among others).

I am fairly certain photos are required....(and one of us might know the bike)

Welcome back Patrick.
I remember that GS1000 thread. It was great going through it again except for the ending.

Hot looking road race bike....hope it worked out well.

The only drag racing I do is to turn 1.....as you’re well used to.

Get a good light and you're on your way. You learn to hate hundredths of a second.

Is it a Bar Bike or No Bar ?

The bike's got wheelie bars, yes. Here's a photo from earlier today: http://brokenbonepatch.com/picts/non_gfb/gs_dragbike/gs_RH_oct_2020.jpg

The good folks at Vicious Cycle set up with a 5.5" by 17" rear wheel over the weekend. The wheel has the same 20mm axle diameter of the stock wheel, which should make it easier to reuse parts like the axle-adjustment sliders, etc. (Wheel's off a 1st-gen Honda CBR00RR, I understand.)

Any special trick to fitting a 26" by 7" x 17" drag slick? I've been changing my own tires for about 20 years now (both tubed and tubeless, radial and bias-ply) but have never done a "square" drag tire. My shop has a dependable tire machine, and I've got access to a Rabaconda if necessary (plus my old trusty tire levers).

Have you made any passes yet? If so post up the slip so we pick on you. Jk.
what carbs are on that bike?

If you've done regular tires, slicks are easy. They are much more flexible than a street tire....

Good news about the tire, I'll update with progress.

Carbs look to be stockers, BS36mm Mikuni CV-style with different jets, and individual K&N pods. @stetracer, any recommendations or good rules of thumb for carbs?

With your set up you should be in the mid to low 10 second range. Do you have a Air Shifter? If not, you should look into getting one. Slick, Wheelie Bar, Air Shifter. The receipe for consistent ET's Good luck and keep us posted.
