Barnett Clutches

Just incase anyone is interested, I have been looking around for some non organic clutch plates for my 280 cc Rotax rebuild.

 

Found some at Barnett Engineering which should fit the bill just nicely and have had the fact confirmed by them too.

You can find them here....  http://www.barnettclutches.com/can-am.html

 

Friction plates are #301-22-10001,  $12.65 each. Steels are #410-37-047001, $6.52 each.  Specify quantities. Shipping is extra.

 

You can order on-line at www.barnettclutches  or call order desk at 805-642-9435,  M-Th, 8am-4pm, Pacific time.  Parts are good in stock, the frictions are made with our

Kevlar friction material, aluminum core. Steels are tempered steel, the ones we make are 1.2mm thick but I’m sure they will work fine.

 

I wanted to use Surflex sintered ones but there are none available until November apparently (someone might have a set tucked away somewhere though), they also wanted €178  for a set.

 

So there you go.

Ok, got the bike put together, fired it up and pulled in the clutch and kicked in first gear.

 

The clutch actuator mods were a little bit disappointing, although that said, I don't know what the clutch was like beforehand. It's not a one, two or three finger clutch. It's heavier than that of my 125 but still not so bad if you ride clutchless as I do.

Anyway, the clutch separated ice cold, so full points there. It also is nice and slipable so the kevlar plates would seem to be doing what they should. I can't say if there was any slip in the higher gears as I was not happy with the sounds the engine was making.

 

More to come.......

It IS still an improvement against the original set up, but will - as you already pointed out - not change the clutch completly!

 

You should have tried the original set up first, I still wonder why they had set up clutch engagement so difficult  ...

Hi Patrik, well after a discussion some tome ago with Reinhard Hallat, he told me that a nice engine had been spoilt by them putting the clutch from a 1925 Hercules onto it.

Also, the testers back then were all big guys and also the sections and riding techniques were a lot different to those used today.

The clutch was only used at the beginning and end of any given section so one or two finger actuation was not a factor to be considered.

 

I'm happy with the clutch as it is, I was just hoping that the time, expense and effort would have brought more.

Yes l too discussed This topic with Reinhard and Thorsten (kattho) the longer lever is the easiest was to "tune" the clutch. Thorsten once tried out the smaller clutch basket of the 125cc, but did it just once. He now as mounted the lever mechanism from the Jumbo unser the petrol tank to his 320 model wir very good effect.

You might ask BRT40 he used special springs and a special handlever.

The lever mechanic unser the tank in combination with longer lever at the clutch seems to ne the most elegant ..

anyway I don't use the clutch very often ... still pleased with what I got now ...
