ive had to replace my SC chain as it was that badly affected by stage 2 gears it could stand alone once removed from bike. Dealer reckons it was due to smaller gears having a tighter turning circle caused this....tuner said he only seen similar on racing r6's, yamaha used to supply cam chains as they revved that high chains would'nt last....only comparing as both chains are quite alike. anyone else heard or seen this....if i get pic from shop ill post....old chain is off to kawa hq im told

The price to pay for you being the research & development
Stuff happens
Glad at least you noticed it before it affected the engine

There are guys with over 15,000 miles using stage 2 gears on the factory supercharger chain, so it's either installation error, or the gears were not correctly made.

Odd that Kawi would be interested in looking at the chain if damage was caused by something they didn't make?

"old chain is off to kawa hq im told"..are you trying to get a replacement under warranty?If so...they will be able to tell if the gears have been switched.

Another possibility... If the chain tension is too tight the oil film will wring out and the bushings will gall and wear out. If not mistaken there are oil squirters pointed right at the chain so the slack area should get continuous flow of oil to keep the bushings happy. I doubt the wear is from smaller diameter sprocket. Each link will bend X degrees as it rotates around the sprocket. To figure the link angle you divide 360° by the number of teeth. And the more teeth there are the less effect each tooth has and the less each link bends. Less bend = less wear.


My $.02 guess is too tight chain or using 0w20 oil.

interestingly enough the SE has no oiler holes in the gear and no hollow bolt , i expect there is enough oil splash from the crank and clutch to adequately lubricate the chain,
if the gear pitch is wrong it will excessively wear the chain and i think the sprockets would not look so good either
bit like putting a new rear drive chain on old sprockets

gears were swapped out sent kawa hq pics they requested chain also. im happy bike is back and sorted dont think they will inspect it csi style and if they do im already sorted. gears are fine no markings so guessing pitch or fact this bike is riden hard has stressed chain. i still have no pics but am told chain is able to stand upright on its own lol.....and it is marked in places somehow.
