so even though i had zero clutch slip issues on the dyno at 300hp, (ive developed an ear for it tuning bikes that make double that) i decided that 3 unknown hd springs may end up causing me grief down the road. typically a clutch will slip in the higher gears, and we obviously dont dyno in 6th. I got a set of Schnitz hd springs which are supposed to be 80 lbs each. they are just slightly stiffer and longer than my unkown hds that were in it. i decided to run 4 of them and 2 oem. 6 just seems over kill, and i dont need to stress the clutch cable ect more than i need to. Ill take the other 2 to loring just in case, when i try to get my old man into the 200 certified club, but i doubt we'll need them.
fyi the brocks springs are stronger yet, about 95-98lbs depending on stack height.
got a 19 tooth front sprocket installed, which requires clearancing the metal part inside the sprocket cover. easy 200+mph gearing now with the extended rev limit and stock rear sprocket. the lower first gear in the trans will help cancel out that 1 up in the front so its not too bad to pull out from a stop.
relocated the crank case breather into the tail and added a bit of protection against spitting oil. these bikes tend to do that with the oil level high, and i like running extra oil. i used a coarse fuel filter with a stainless element as an extra means of catching and separating oil mist from the case "fumes" with the intention of it self draining back to the motor after a high rpm blast is over with. i have a similar setup on my turbo lsr bike, but it was all hand made. this was quick and easy, just machined the -8 ends to a single hose barb.
next up are tires and connecting the rear turn signal wires. then a safety and insurance.
