About 50passes my guess

My last 3 passes of the night I backed it to 7* not different in times or mph then also the the end of tge night I let 2 other people run it one person ran a 6.5 at 92mph who weigh 40lbs more then me and another ran 6.3 at 94mph weigh about 100 lbs less then me. Then I went to take it for a run for shits and giggles and the clutch was smoked. It wont even move what is your thought on this issue?

I will get u a picture this afternoon of that

Here is the up to date plug check. I consistently ran 6.1s any 94-96mph. I changed my timing from 10* to 8* felt much better. Also i went from 2.4 at the beginning of the night then switch to 2.375 gearing didn't go any faster. Do u think my clutch maybe slipping now? Any ideas on what to do now? I still beat every one to just pass half track then they go around me. They ran from 99-103mph

Interested in flywheel

No. It was ported by redline I bought the cylinder used off a member

I was running 90-94mph I need to be in the 98-101 range thats about what everyone else runs. If I turn back the timing will I need to regear it. Which the gearing and timing I run now it comes out awesome just the big end I need to figure out.

165-170 compression and .045 squish tires 69rollout(22") cut turf tamers fuel 108 octane 40:1

2.375 gear ratio with 2.81 primary just quits pulling a shorter and I think I have 1.8 float valve. 39pwk with 48p 178m 1.5-2 on the air screw and with dgh needle. I have shearer supercub pipes

K This plug is from 4weeks ago I dont have anything recently next race is next week I can another plug check then

I never posted a photo before on here how do I do that

I got a 521 running 500ft. Gas motor, 39 pwks +10 timing what for timing are guys running on motors? Tring to compare 300ft motors to 1/8mile motors. My motors fells like it quits pulling when I hit 5th. Could I have too much timing?

Looking for a 10mil supercub cylinder and a set of domes

If I can get it to rev more I know I can run that gearing

I was running consistently 6.1s @95-97mph anther guy I run has the same motor with stock ignition and slingshot (but idk what they are set at ) and same tire and his gearing is 16-38 amd another 465cub run pvl and no lockup both and same gearing as above will run 5.8-6.0 @ 110-104 mph

E22x11x8 hi-run (knobby tire) roughly 69rollout and its on an adjustable plate

My motor is a 521 supercub. The first race I had a pvl on with no lockup timing at 80-85 thousands and I had 15-37 on for gearing I was running out of gearing before the finished. This race I was told to put my stock ignition back on and run 3stock and 3hd springs with all the balls in the lockup ( it the gigot sytle)my timing was 7-8 ish and 15-37 and now it wont even rev out the hole way in 5th. Need some advice Could I have to much weight and holding the motor from revving or does the stock ignition have a rev limiter in it? Idk any advice will b helpful.

K thanks

Never heard of noss machine. Are they a sponsor on here?

Im looking for a set of custom cut domes for my super cub. Who do u recommend I need them by this Saturday for the races.

What kind of tricks can u do to keep a clutch cool on slipping

Im use to running a pvl on my drag b anshees. I bought a stock ignition to try i was told it helps to get a little more grunt. If I spin tge crank with my hand it turns hard with the flywheel on and if I take it off it spins like butter. As if the magnets are really strong. Is tgis normal? It doesn't rattle. Tgey are all one parts

What's the difference between the 423mo7200 piston and the 10018mo7200 piston?

Looking for a used set of pistons and domes for a supercub 72mm bore
