I gotta ask, why in the hell is the bike that long? That's way too much arm for a stock motor.
As far as shock recommendation, get with a sponsor and buy a JRI, Penske or Ohlins built to your specs. A stock shock is useless for your application.
Yeah, 58 is commonly accepted as stock wheelbase but it's a fraction more. The op's bike has a long swingarm. With a stock motor, 14 over is pointless. Now if a guy likes the look of the arm, so be it, but it's counter productive if you're trying to race. The tire will unload and spin for days....I looked at the specs for that huge Indian Chief and it's wheelbase is only 68.1” and the overall length is a whopping 103.5”. That’s over eight feet. Isn’t our wheelbase around 58”? Maybe it’s a dragbike with wheelie bars?
Even spraying the full 80 out the gate you've got too much arm. At 72" you're in grudge bike territory, and those guys are 500+ hp.Yes, it is a drag bike that will see a little street time every once in awhile.
It will be getting a 60-80 shot as well.
It will also be on a shinko hook up tire if that makes any difference.
Thanks!
At the moment I don’t. But that’s the next thing Iam buying for the bike as I have maxed out what I can get from a stock gen 2 shock on my bike. A friend of mine just got his m2 and loves it. They ask a lot of questions so they can build you the shock as close to what you will need.Sounds good. I will definitely look into them. Do you run an M2 shock?
The major issue is lack of traction. With the rear wheel that far back and not enough power to transfer weight to make it stick, it will spin. I know you said "as long as it hooks", the question becomes what tire pressure do you have to run to make it hook? The lower the pressure the higher the rolling resistance, the slower you go. You want it to hook at the highest pressure possible, and to do that you have to transfer weight. Yes, a drag shock will absolutely help you do this, but an arm that long is working against you.Thanks for the input. What are the issues with going too long on the arm as long as the bike hooks?
I'm looking to be able to put the most power down and not pick the tire up on the launch.
Also, not looking to use the stock shock/spring. I'm leaning towards a custom penske shock at the moment.
Lots of guys like the M2. Many of the fastest pro street guys run them. I also have M2 forks on one bike.Ok, thanks for the explanation.
Thanks for the input Dennis. Good to see someone running the M2 shock and liking it.
Is that a hand clutch Dennis?That is 1/8 mile, so 660 feet. Pretty common, especially in heads up racing. It’s long enough for me to go 149 mph. It makes it a racer’s game not just the guy with the most hp.
Hays Revolution hand slider. I wouldn’t be as consistent with a stock type hand clutch.Is that a hand clutch Dennis?
