Barnett clutch plates

[Paul466]

Hi All, I wanted to get some opinions from ones that installed this kit, out basket has a circlip style wire that holds one friction one steel plates, After measuring thickness found the friction one same as oem but the steel was thicker, I was within spec so i put the two oem back and used rest of the plates from the kit? Called Barnett and got a blurry answer….What am I missing?

Ive done this and just put all the Barnett in. Has worked fine. IMOP, I still prefer the feel of the stock plates along with the use of the Barnett pressure plate.

Barnett uses a different friction material (probably more "heavy duty") and this might be thinner. The steel thickness might take up the lack of fiber material. Just a thought....

I didn't MIC the parts, I just installed them and off they went.

********** Make SUPER SURE that the little circle spring "ears" are correctly re installed. Take your time and make sure its put back properly. Its easy to mess up the ears. Also make sure the spring (wire) is in the grove after you know the ears are in the trooper location. They both tend to move around... Check and double check.

Was the clutch pack getting replaced due to wear? Or an upgrade?

I had a 550 SECA that I thought the clutch was worn; slippage. Put the Barnett kit in, and took a look at the OE. As it turned out, my issue was just weak springs; clutch plates were fine. I thought my FJ's clutch was acting up, again with slippage. Before wasting money on a clutch kit, I took the old clutch pack & the weird circle spring to a tech I trusted. First thing he did was remove a very thin wire from between some of the clutch plates and throw it away. Apparently, Yamaha puts that wire in there as a wear indicator. As your fiber wears, the wire prevents full "clamp", and allows slippage. As it turned, the clutch pack was still good, and my back tires was breaking loose at about 6,100 rpm.

My point is, if you're replacing for "wear", it may not be worn out.

Thanks for the info My bike has 65k so it was just winter love for it, OEM wasn’t missing lots of fiber (I’m not a revver or red liner

Reving doesn't hurt the clutch, but spending a lot of hard time in that "grey area" wears it out though.
