Dragging an XS11... and not with a truck

[kirmit77]

What is yalls thoughts on taking an XS11 and lowering, extending and high horsepower?? Let me know

[WMarshy]

Only thing I'd be interested in is the high HP, dont care for raking it out or lowering it. I scrape exhaust already, dont think Id like both sides too... Im sure somone could come out with a cool looing essentially 'chopped' XS all raked and lowered but its just not for me. BUUUT, if your talkin about making a XSessively fast drag bike then IM ALL FOR IT. I always wondered why the KZ's were picked over the XS to make a drag bike from...

Wow. I hadn't read the print until now. 7.57 seconds Other than the giant supercharger, I wonder what else they did to the motor. The problem with a drag XS; it's heavy, and other than a mild big bore, there are no aftermarket performance parts manufactured. Which means if you were serious, you need serious cash to have one off parts built or the knowledge and tooling to make them yourself. They drag KZ's because they are lighter, already chain drive, and I can go to the APE website right now and buy a 1400cc kit amongst other things like titanium valves parts.

Yep I agree with 81project. Why not drag an XS, same reason folks always drag a chevy or ford but not to many Olds engines. Parts availability. I can to the shelf at Summit or Jegs and pull off enough stuff to turn a Chevy 454 into a 10 second car on an old Impala. But try that for a 455, not hardly.

There is one more reason I forgot to mention which is directly associated with parts availability. There are SCORES more kz's out there. The kz was produced for 2-3 times as long as the XS so there are tons more out there.

who cares about whats cheapest, be different, do it!!!!!



Oh yeah, then come back here and tell us all how you got more power out of it.

That would be pretty sweet if those cylinders would slip down into the base of an XS motor... and the piston pins fit our rods.. or those rods fit our crank. Even if the crank was a different size, if the spacing was right, you could take a stock crank and get it welded and turned to the right thickness and use that KZ stuff from the cylinders up.

I know there's other problems, like the XS crank gear teeth and cams from the Kaw have to match.. and exhaust problems.. but it's a nice thought.

Dgxser is dead-on with the comparison. The only one I've seen here in the States that has even come close and still have a streetable XS, and a very nice looking "sleeper" I might add would be Dan Hodges here on the site. Read here all that he has done and had done as far as one-off mods to get what he's got. Gives you an idea of the bucks spent to produce a very impresive naturally aspirated scoot. An Aussie member here has gotten a bit more ponies at the rear wheel(dyno proven), but again, more aftermarket options were and are available to these folks and those across the pond. An aftermarket turbo WAS availible back in the day, and some still exist today if you can find them, but again your gonna give up motor longgivity adding ANY kind of boost. They are what they are and your gonna spend mega bucks to transform that rated 95horse AT the crank to anything not much over a 100 at the rear wheel. None here are being negative, just sayin'.......
