SLED BOGGS DOWN..... HELP

If you go for a long burn, say 15 min at high RPM, come to a stop and hit the kill right away. Then pull your plugs and check the condition of them. If they are moist/wet then you most likely have the carbs set too rich.

My guess is binding in the secondary clutch which could mean bushings worn or weak spring.

I think you guys are over thinking this one. It sounds like a worn out belt to me!!!

has it always done this? or have you recently done any mods ?or did it just start doing it?

smoke it if you got it

My two cents

In high perf machines. Dont the spark plugs plug up a bit if you were running fast and then idle for a bit. The spark plugs will start to gum up. Carbon buildup and all. This is the same when you run fast for awhile and then shutdown your machine without a warmdown. Just a thought. Im no expert, just trying my best. So don't flame me too much if I got something wrong. Just correct me so I can "Be all that I can be"

Yeah your right..... it could be the belt.

Ok - i'll risk acting or being dumb. Why would the belt cause the conditions Drastic_440 is describing? He says he has to trottle till it FINALLY revs... Is it because the belt catches at an earlier RPM and causes a boggin? I would think it would slip more and he would have all the RPMS he needs! I don't have answers, just looking for em

Well if the belt is worn, it will ride lower in the secondary clutch. When it rides lower in the secondary clutch, it has a major effect on your "gear ratio." well technically its not a gear ratio, but you get the idea about bigger and smaller pulleys. Although im not sure this is what the problem is, i would actually have to have a better description of the complaint before i would condemn the belt.

Polaris is my way out - Other people just use a door.

I am going to say it's something simple too. I had the same problem with my Indy 500. I was running too cool of a plug and it was fouling the plugs. At high rpm's it was fine ,when I got back on the throttle it would bog down then come back. I then found out I was running the wrong plugs.
