How quick is your GS

[skip]

Stetracer,
that is really impressive work you have in your bike. Its funny you mentioned CW(carl and russ nyburg) they did my head 10 years ago although it was just a mild port job With oversized exhaust valves .(intakes are stock I think.) They also did the Original bore job when i went to my bigbore kit. Im running mild cam motion g-4,s . I also put in heavy duty studs and had the crank welded( Falicon) I have 38 rs mikuni,s and run with dyna s ignition and coils with dyna rev limiter. (Wich is not working right now) . I have a star racing clutch basket with the welded backing plate and barnett clutch and springs.The transmission is stock and i use a vance and hines "quickshift" Electric shifter. Looks like most of your hp is coming from that headwork and cam combo you have. Can you run that on pump gas?
I thought about spending more money on the head, but I dont thik ill see the dragstrip this season. I Originally built the bike as a sleeper With every thing hidden, but lately Ive been turning it into more of a sport tourer and less of a dragbike. The last ride at the end of the season we went a little over 300 miles on a sat. and the bike was flawless.

Can I have some of your leftover bits

I will fight you for the leftovers!!!

OK, here goes. 8.95 @ 172mph. GS1000 (2V) bored to 1238, Wiseco Pro Stock pistons 13.5:1 machined down to 9.5:1 to run NO2. 34 mikunis, Hand built 4:1 megaphone exhaust, M&H 6" rear. Lock-up clutch, standard Suzuki clutch plates, double speed oil pump, o/size inlet valves, std Suzuki exhaust valves. I also ran 9.50 without nitrous. On the 1/8 mile I ran 5.1? @ 131. (I might be wrong on the 1/8 time but speed is definitely correct). I couldn't afford to put a bigger rear tyre in, so I was always struggling for grip!

Paul, that is indeed some huge MPH. Guessing around 275 hp or so? Which cylinder head are you using and what have you done to it.

Derreck Pierce has an animal that riuns in the 8s naturally aspirated and i believe without nitrous . But i never see him post.

To go fast, all those fancy parts are great, but all I have to do is wash mine.

[Paul]

I don't know the BHP, never had it on a dyno. It has the later large port head. The head has been fully flowed, has oversize inlets but standard exhaust valves.
What Sean said about our "tracks" over here is true. I went to York raceway one time, it rained and there was deep puddles of water lying on the track - that shows how uneven it is (was?). At North Weald I was shot off the seat by a bump in the left-hand lane - this was just about 400 yds out! At Avon Park, I was told by one of the Top Fuel guys how to ride it - that was to go flat out through the finish lights and keep it screwed on until you had passed over the cross runway. The theory being that you would take off on the bumps but land well past them, whereas if you turned the throttle off the front suspension would compress, and when you hit the bumps you would have no suspension left and thats when the trouble starts.

Paul, that is still impressive MPH. My GS1000 2v sports 1085cc, turbo'd at 18lbs of boost on one of the older small port heads and dynos 188hp at the rear wheel. So far has been 5.88 @120mph in the 1/8 mile, with more gains in it as tuning and riding develop further. All this with 285 lb rider. I imagine it would really sing with a normal size rider.

[Paul]

I suppose I do have a bit of an advantage there, I weighed about 170 lbs then! Also don't forget it was a 1238cc. I'm a firm beleiver in the old adage "theres no substitute for cubes" The other thing I was running 100 octane fuel.

If your over 140 in the traps your doing great!!! Good luck in helping to keep the sport alive!

[lhanscom]

I was thinking about running my bike on the drag strip this summer. Any tips on how to do well?

Ihanscom, tell me about you bike and ill tell you what worked for me. I raced my bike with stock chassie and small stock tire and my style came out of necessity from having those limitations.
