all I can say is WTF causes this my belt wore or burnt through my secondary

Here is what I am running I guess my question is will a heavier secondary spring fix this

8bu00 62.08 grams
BGB spring
14.5mm rollers
Hi-tech speed ring

silver secondary spring at 80
I just cleaned inspected and rebushed both clutches

This was in 4ft of heavy powder on an Apex MCX310 with a 162x16x2.5

Your secondary spring is wayyy too soft. Toss it far far away & use the white.

Too much Helix and Not enough Spring.

What helix do you have?
 
how are you running only 62g of weight with a 310 kit...im running 84g

primary
bwb
dalton base 70g load up


secondary
51 deg helix
epi purple spring wound 1/0( 2 guys almost to put it together)
 
the helix is a custom ground 51 so I will chuck that and put a 47 in it and try to find a stiffer spring Turk is the white a Yami spring. Boost its a stock belt. Turblue I can get away with less weight because I have a boost controler and dont run it at 310 more like 240

Thanks for all the input guys :Rockon:

ive tried the 8bu-00 never worked for me...the only way would be to add more weight to like 78-79g which would have to be custom made side plates
 
Supreme tool clutching. Expensive quality stuff.
I can get the stock yamaha stuff to work great to just over 300 hp.
wrap the white spring at 60-80 wrap.
