Looking at extending my stock swingarm for drag racing.I work at a metal fab shop so i will have it done there. I did not no how many inches i should have added. Also do i need to lower bike after extending swingarm? If any of you drag racers out there could give me any ideas on swingarm or anything else to get me started in setting up my bird it would be great. Thanks

In general, set up can be everything. Strap that front end down and you may or may not want to lose the shock and trade it for a strut. The biggest problem you face is weight, which has little to do with a flat out top speed run and everything to do with an acceleration run like that 1,320 feet you're trying to cover. You will also want to change the gearing as you want to be in 6th at peak horsepower rpm just before you hit the traps and that won't happen at 17/45. At 15/48 you would be geared for 152.1 mph and each gear will give you roughly 20mph starting at 57.2 in first at 10,800 rpm. You'll have to play with launch rpm and you'll need some good rubber on the back for sure because that rpm is likely to be around 5,000. Michelin is finally making a solid strip tire.

Good luck..

Hey thanks for the info.

Mine is set right now at 8" and it's too much,but over gearing will only result in wheelspin.There is a common ground to be found between the two.I ran the same gearing as last year and struggled to get traction with a shinko ultra soft tire this year,I had no problems the last 2 years with my Metzeler dragtech and I'm sure the difference was not the tire.It will also depend on how much power you have and how fast you get through the gears.16/46 worked well for me for years,add an air shifter and 15 hp and its not right anymore.I have 150 at the wheel and that gearing used to leave me flat out in 5th at 138-140 mph.I now hit 6th too late but can't stay in 5th.Tried 15/46 and spun all the time,had to back the launch rpm down to 7000 from 8000.Going to try 15/45 then 15/44.

I believe you. They are not invincible on the road, either, particularly where there are twisties.

its great that suzuki came up with a name that any 2 year old can say lol

Partsguy · 09-10-2009, 7:50 PM

15/45 seems to be the ticket.

9.70
Can't complain.

Damn skippy! I'm still waiting for you to produce a kit for this.

TESLACOIL · 11-26-2009, 10:12 PM

extreme gearing....

In principle if u geared 6th to top out at 150mph redline this would give the best results

1st and second will be hard to handle...but good throttle skill comes in here

3rd onwards you should be able to prevent wheelies and weelspin

HAS any one tried it ? 50 to 60 tooth rear sprocket ????

I have a 15 /44 set up that i am going to install. I was warned that a 15 tooth sprocket might very well align the chain so low that it tears the crap out of the plastic guide on top of the swing arm. Do we need to replace that strip constantly with delrin strips? How long would a delrin strip last? Not long.... I cant think of a way to route the chain higher. I was told to switch to a 520 chain for drag racing too.
I am pretty upset about my 15/44 and chain i bought as a package. it sounds like i cant even run it on the street, only for the quarter mile as wear will be too great. i am pissed..Any solutions to this??

Partsguy · 01-16-2010, 11:15 PM

I'll have to look at my swingarm,haven't heard or noticed anything yet.I don't have a stock swingarm on anymore,this could be a factor.

who's swing arm do you have?

TESLACOIL · 01-17-2010, 6:48 PM

it will handle like pooh round corners with an extended swing arm....i lowered my rear end by 4 inches and just doing that made the handling suck

just in case anyone wasn't aware

BigDave · 01-17-2010, 11:15 PM

parts guy, can you click off consistent 9 second quarter miles mow that you are re geared with only 150hp? I believe you. My mate thinks you are lying. But he can be Mr negative sometimes. Extended swing arm?

I hope to do nines with my set up but not sure if i can with only 140hp and my 15/44 set up. I just have to stake my chain tomorrow and i will be done. I do have a SS set of down tubes to install still/. I may have picked up 3-5 hp with new plugs, dyna coils and dyna wires. Who knows. I wont be able to tell since i am re gearing at the same time.

So, if i have 143hp and my gearing is nines possible? I dont want to ditch my center stand just yet. I am loving it to death using it to work on the bike. Maybe if i get a lift of some sort....

The rubber swing arm guard is in good shape after 30k miles. I think it is tough as nails and it can be replaced in 2 minutes if it wears out. I dont think a 15 tooth sprocket is going to kill me. Any touring and i will switch to 17/44....

This is my first bike that demands a staked chain and NOT to use a circlip. Honda is pretty adamant about that. Why? I have never heard of a circlip coming off.

I have to buy a cahin breaker and riveter tomorrow. i had to use ,my dremel to saw my old chain off this evening. WHat a pain....

outlawgibbs · 01-17-2010, 11:32 PM

Im running 10.20 with only running a 16 front and 140hp and swb. Lowered 3in in back and strapped the front. And I have the tickets to prove it.

I dont doubt that at all.
Do you think you can run into the nines with a 15/44 15/45?

Yesterday i saw a basically bone stock bird click off consistant 10.40's and less. Good rider helps.

what is strapped? Just lowered or somenting different?
how did you lower it SO much in the back?
