100hp honda wrote:stock clutch is aproximatly 14 oz ? steel clutch is aproximatly 40 oz ?.... is that with steel fiber plates also ? seems to me like alot of weight but i havent tried a full steel clutch so i cant say the seat of the pants feel. adding 26 oz to a 350 chevy would be miniscule, but in this small of a engine i cant see how you wouldnt notice that . and i understand the point of not wanting the oil contaminated, and i have seen how it contaminates the oil, but ive torn down 2 motors that were nearly 10 years old, both used aluminum plates probly their whole life, and i seen absolutely no sign of any increased wear on any bearings, seals, gears or shafts. this is just my observations
100hp I think if you used aluminum plates and changed the oil often there isn't any real disadvantage. My opinion is that most riders don't change their oil often enough and should probably use steel plates because of this. I also feel the weight difference in the clutch alone isn't as noticable because it doesn't turn at the same speed as the crank. A 16oz flywheel weight has a larger impact than 40oz of steel clutch plates. In regards to clutch kits alone I don't think there is a real weight advantage one way or the other. But if a guy chances his oil as often as I do and goes through pains taking efforts to reduce weight and parasitic drag it would be like shooting myself in the foot to run steel clutch plates...
ya i think alot of people let their oil go for a whole summer . i dont keep a log book but i try to change mine after everyday of riding or after 4 hours run time if i dont ride all day
as far as the weight beeing underdriven to the crank speed, its stil completely relevant to the crankshaft because it doesnt disengage, like an engine with ballance shafts, take em out and it picks up rev way faster.
Ever run a kenda tire, then change to a perelli same day?
I understand. But the crank has mechanical leverage on the clutch that it does not have with the flywheel. I just don't think I could tell a difference of +/- 1.5 lbs in my clutch. Like I said, I've taken just over 5lbs out altogether. If I cut that by half it would be difficult for me notice and therefore justify the gains.
