Well all I know is........... Makcap helped me re do mine and the results are Zero slip. Burnett Basket, Great, use the right tool to tighten because if no, I think I bought the last extra one in the country.
My helper forgot the tool at home and i could not wait, well, I waited another week.
He has another secret I don't think he's disclosing.
and I can't tell either. But I would imagine it alone would cure any clutch slip even factory.
I tried the Heavy duty Speedstar. I have one and I also have a good factory spring. If anyone wants to waste your money you can make me an offer. It's well stored in my junk box. Total waste of money. Absolutely no difference from the stock clutch beside being harder to pull.
Burnett with the new friction plates, Makcap's little secret, and total lock up.
Caution though, I think they allow slip for a reason, once you obtain true and total lock up, a little modification in your riding technique is in order as there is absolutely no forgiving being lazy about pulling the clutch.
And that freezer bag trick is Waaayyyyyy too cool! Wow!

MS1700,No disrespect intended as i know your a good bike wrench but what you posted doesnt seem add up.
As you just stated the speedstar clutch spring does in fact have more tension that makes the clutch harder to disenguage like you experienced because in fact it's a 20-25% stronger cltuch spring which make sence.
With that said you fell short of saying you actually tried a brand new HD speedstar spring (not a stock spring) but said it basically sucks so i was wondering if you did in fact try the HD speedstar spring along with new clutch plates and had it slip in a stock or mildly moded R* & thats why your so negative on using it that HD speedstar clutch spring with 20-25% more clamping force?
Just asking because you had such a bad /neagtive reaction to even using it but never said you actually tried it either.
I dont see how a brand HD hi perf spreedstar spring with either 20% or 25% additonal clamping force would slip when a stock
yami clutch spring with 20-25% less holding/clamping force
doesnt slip when its brand new in a stock or mildly moded R* (No hi comp pistons or hot cams) & or at least for at least 8k-10 miles or more in some cases with stock motor and normal riding not overlly agressive riding style.
BTW,My 06 has almost 15k miles on it with pipes & original stock weak clutch spring and i can speed shift it holding throttle wide open and the clutch still grabs just fine riding 2 up with bags loaded not that its really going anywhere fast which we all know it aint!!!/LOL!!!!
But i realize its a matter of miles/time before the original clutch spring bites the dust.
Heck,my 33 yr old original kawi 1000 with 700cc less cam blow the R* in the weeds and it gets 52mpg riding 2 up too but isnt as comfy as the R* is which is why i bought the R*.
But it just doesnt make sence that a clutch spring with 20-25% more clamping/holding force then stock clutch spring would be NG as you suggest and slip etc espcially whe its brand new.
