alright i got a 00 indy 500 with a rebuilt primary and secondary w/ a new belt and the spring on the second notch. The sled takes off at about 5 k and seems slugish untill you really get on the gas. The motor was just rebuilt top and bottom. I have not checked the belt deflection, but the belt is about 1/8th of an inch from the top of the secondary (i think thats where its supposed to be) . The guy before me did the primary and you can tell its all rebuilt, And i rebuilt the secondary. what do you guys think?

also just to learn... how do you adjust those three bolts on the seconary? i read to put a flat bar across the belt, and if it moves 1 1/4 inch, its good. But how can i adjust it with those three bolts?

Your belt should stick 1/8" above the secondary at rest. Deflection at 1 1/4". 5000 is high for a 500. Ours did well @ 4300. Need to know how the sled is set up for clutching, gearing, & jetting to give better info.

it has a blue/white primary. Sorry but thats pretty much all i know about it to be honest. The gear is stock that i know of, and im not sure on jetting either. We just bought it about a month ago

look on the back of the helix for a number like r-36 or just a 36.
then write down the color of each spring, and with the belt off you can pry the primary closed to see what you have for weights. compare them to stock.

its 100% the secondary. I took the clutch off and put mine on and it takes off at around 4k now but it still feels a little slugish...maybe im just used to my 600. Ill check and see what it has for a helix when i get back on monday. I may just end up buying a new clutch for it and call it good!
