xs1100 turbo

"??? Then why is it at the race tracks, all the hot bikes like the 'Busas use a strap and ratchet their bikes down to take out the suspension to get the best times? You want the power going forward, not raising up. "

I've never seen them take out ALL the suspension at the track. They will preload the shocks, so as to limit the amount of travel, because you don't want the bike to squat or buck suddenly.

Drag vehicles use a portion of thier power to put weight on the rear tire(s) to increase traction. With solid suspension the rear wheel will break loose too easily. However, the XS seems to have more download than it should, which is why it wants to rise up when you hit the throttle.

Maybe these guys found that the happy balance was those struts at a precise length...

Hey Cnuk, yep you leave the suspension in play ONLY because you NEED the weight to transfer to the rear to plant the drive wheels. But even then, I have air bags in my springs that I preload for the track to take most of the travel out. Of course, with the torque and power I have in my drag car, it also pulls a wheelie so it does transfer the weight to the rear.

Seems liek these bikes have ALOT of the weight in the driver and such and the frame weight goes toward the rear anyway, so you have the weight to plant the tires. MY XS does not lean back when I hammer it, it seems to stand up.

I still have the best 0-60 time ever on an XS...

That's probably what it does best...

Looks like it might be burning a little oil. Might be the turbo shaft seal.

My mom had an old honda CVCC wagon that did that every morning when we backed out of the driveway!

I wish I had the $$ to waste on tires like that! My neighbor just burned through a brand new $300 wide HD tire just for the heck of it. I don't get it....

[cywelchjr]

Me either. I scrape pennies together to get new rubber and these guys just burn it off. I want my tires to last a long as I can get them too, not in time, but in miles. This includes the tires on the cage, the more miles I can get from them the happier I am.

I think they all did that. I had one of those to, called my Bond Mobile, james bond. My secret agent smoke screen getaway car. Did the same thing right up until I was driving home and the oil light came on and I had no money for oil, soooo.....one rod through the block later the fire department came to put out the fire of the oil in the engine burning through the hole. They get REALLY noisy at 70 MPH with no oil in them.

Look at that last pic at the track where the wheelie bar attaches. Now we know why that bracket is there and the shocks are gone.

And.... Air cooled motors, especially with turbos, LIKE stationary long burnouts..

But for all the fun we are poking at this guy, if XSCHOP were to start producing a bolt on turbo kit, there would be another 452 post long thread about how we could all get one... I think we are maybe just a little bit jealous?

I used to have a twin turbo stealth and my stock '79 Special feels fast to me...

I can't IMAGINE what that bike would be like.

Hell yes we're jealous! How could you even expect this group to act like grownups???

Still think he needs to fix that oil burning problem.

You know, I had a Plymouth Sundance with a turbo, and ridden in a Cutlass wiht a supercharged 454. All I know is the stock XS kicks both cars ever livin A$$es for torque and acceleration.
