hey everyone i have a stock 1990 indy 400, my buddy and i have the same sled but i am just a little faster so we decide to do a little cheap build off and race them again next year. im looking for your advice on clutching. mine boged really bad so i took the secondary apart and tightend the red spring one hole and made a huge differnce,but looking to make some changes to the stock drive spring and weights. there is a light blue spring in it now. the sled has over 6500 miles the spedo broke before i got it so im sure its due for a service. we are only looking to spend liek 350 on our build off nothing crazy. is there any other items i sould look at for more low-mid end speed. i really would love to get it alittle louder but is that possible with out spending liek $450 on aftermaket pipes if even made? let me know what you guys think or if any of you guys have done to your own 400's these our our beaters but i have more fun riding it then my newer edges.
