He's not adjusting the backpressure. He's adjusting the pipe itself. Slippy pipes have an inner adjustable convergent cone. By pulling that handle behind the wheel he is pulling the convergent cone towards the header end of the pipe, effectively shortening the pipe length. For 2 stroke engines, a shorter pipe (from convergent to divergent cone) "moves" the power band to the top of the RPM range (to put it in simple terms). It's essentially a gearbox-like solution to karts with no gearbox. When he's almost done accelerating, he releases the handle. Then backpressure plays a role, allowing the convergent cone to slide back to the exhaust end of the slippy pipe. A longer pipe = power band shifted to the bottom RPMs = more torque when you need it most, which is out of corners.

My best time at Daytona ever was a 2:08 running 750cc Superbike (GTO) class. Top speed was 191.4 mph. That was a while back. I'm 54 years old now and not racing anymore. Wise decision on my part lol.

I ran WKA with a B-Bomb 135cc open engine back in the 80's. They put out a lot of hp and were dependable. Lots of fun and definitely less expensive that my sprint car was...LOL

The engine looks like a komet k11. I ran one back in the 80's along with a slippy pipe. I was never lucky enough to race a Dayton. Looking at the speed advantage you have, it must be a 135cc engine. Great video, Thanks!

Agree. It's got to be a 135. And it looks like a Komet. The other 135 that was popular was the BM 130. I ran a K78, which was a 100cc.I ran Roebling Road and Rockingham. What a ride. Very exciting, wonderful memories. Also ran Charlotte, which was a ride also.

That's impressive. A 2 minute and 19 second lap (he did two in a row) is quicker than what you'd get out of a 2018 spec Mazda MX5 Cup car around Daytona with no draft.

At Willow Springs, Karts rule. Only a Porsche Turbo and an Indy car testing turned faster laps. And the Kart could hold onto the Porsche when drafting for several laps, only losing it in the climb after turn 2.

This was the least expensive road racing one could do. You could run Daytona, Charlotte, Rockingham, Roebling Road, VIR, Carolina Motorsports Park, Barber-Saab. These are not your typical go karts. Jeremy McCart from Morrow, Ga. had the Guiness Book of Records in a go-kart at Daytona with the WKA sanctioning body. Even though it was a 450-cc Rotax Shifter kart, he recorded a back straight speed just over 210mph and a 1 lap average of 151+mph. A record that still stands for a go kart under 500cc. He was a hellava driver

I like your slippy pipe cable set up, boy have things changed from my day. I raced against the Fulks boys and Todd Spaude who were very hard to beat back then.

He is adjusting the pipe. He pulls it in on the top end and lengthens it on the low end. Just because were Road Racers don't mean We don't make adjustments. Some of us lean and richen the carb as needed on different parts of the track. And it takes balls to drive one like on this video.

first off he most likely isn't even adjusting anything as even on a laydown there isn't anything to adjust there well except maybe the throttle cable. The pipe being behind the drivers head. Second these are enduro karts that race tracks built for full sized cars so they need to have maximum top end, lying down provides less air resistance and thus a higher top end.
