hey guys i just recently put a bombi suspension with a 136, inch and a quarter ripsaw on my 98 700 srx it hooks awesome even with no studs compared to my old pro action with the 1 inch track. so i decided I'm going to race it at the local sled drags for shits , the track is 600 ft snow track , my gearing is 22 40 right now and my clutching is a dalton 54 46 with a green spring wrapped at 70 , for the primary www spring with 8dn20s 4.5 grams both holes any recommendations on how to get it to work better for the 600 ft , gear down to 21 40 ? would freshening up my 3 year old springs help ? my rpm is 8500 which also needs to be dropped to 8300 any suggestions?
