Awesome, I drag race a couple if my RZs hundreds of times, was so much fun, especially back in the 80s beating so so may bikes that were much larger.
Out of all the road going,off the shelf pipes.You have the best for dragracing, no doubt. I ran a 15 tooth front sprocket, lowered my suspension, a "aired down" roadrace slick, I always used a steady pinned throttle style, as otherwise it just wheeliesd or pogos, if that happened it was iver. I just pin the throttle to my laubch sweet spot, hold it there then drop the clutch. At sea level, I managed somewhere on my best ever of a 11:40ish over a 1/4 Mile. Usually it would always lay down midd 11s with accuracy.
I gave a couple Xtra frames...I'd So love to do a drag RZ with a cheetah cylinder and Full side exit drag pipes, I know I could break into the 10s even all these years later. Lol All the drag strips have disappeared....Sad

Awesome, I drag raced or a couple if my RZs hundreds of times, was so much fun, especially back in the 80s beating so so may bikes that were much larger.
Out of all the road going, off the shelf pipes.You have the best for dragracing, no doubt. I ran a 15 tooth front sprocket, , stiff barrnett clutch, lowered my suspension, used a "aired down" roadrace slick,.
For my reaction times I always used a steady pinned throttle style, as otherwise it just would wheelie or pogo, if that happened it was over. I just pin the throttle to my launch sweet spot, hold it there then drop the clutch and it's GO time! At sea level, I managed somewhere on my best ever of a 11:40ish over a 1/4 Mile. Usually it would always lay down mid11s with accuracy.
I have a couple Xtra frames...I'd So love to do a drag RZ with the following..
1.) A Cheetah big bore cylinder.
2. ) Full side exit drag pipes.
3.) + 7,+10 or more!! stroker crank.
4 .) Full lockup clutch.
5 ) Full drag port.
6.) Undercut trans

Similar to this..

I know I could break into the 10s without question, even all these years later., with alky possibly into the 9s. Lol All the drag strips have disappeared....Sad

The trophy is the best part of that whole story! I read the short'er' posts. Good stuff Steve! What sort of displacement were they running in those other bikes? Shows what poor performance they end up with trying to emulate harleys!

Great job Steve! Very entertaining read, thanks for posting that up. So are you going to round 3? Is it at Rimbey as well?
Might have to change your onscreen name, lol.

Enjoyed that story.

I imagine your little bike will be the hot topic with those Drag Racers.

Steve said that the RZ garnered a lot of attention. Rimby was back to back rounds, Sat and Sun. He's coming up to Edmonton this weekend to try his luck again.
