Clutch Bearing Mod

[scot taco]

Very nice 199a in the classified adds and it mentions that it had the clutch bearing mod done to it.

 

I,m more curious than anything as I seem to have mine working pretty good,but does anyone know what this mod is?

hi scot yes my 199A has this mod the ignition case is where the needel roller bearing is its been  bored  out and a grease nippel has been fittted to gether with barrnet clutch plates  and a longer clutch Arm and good clutch set up its V/ light.

I also had mine done, a needle roller bearing is inserted in the ignition case for the clutch actuator shaft to move on. Nice little mod, I couldn't feel a massive difference but it's easier to maintain with the grease nipple and not expensive. Overall definitely worth it.

Have a look here:-

Before everyone starts planning this mod. Only the 198A/199A cases are suitable. The position of the locating screw is positioned lower on these cases. In the earlier cover the screw is where the bearing is positioned.

Edit

I should have stated 198A/199A cases onward

Thanks for the replies and you are correct Stuart.I t didn,t dawn on me until you mentioned it,but it should have because I found that out when I went to put an earlier model actuator shaft in my 199a.

I have often wondered what the hydraulic clutch converstion offered by Romero Motos are like.

That looks like half a 2 pot caliper used as the slave cylinder rather than the dedicated slave cylinders that modern bikes use

May ne a very early modification?

Anyway the bearing mod does have an effect at least to my bike as it still have the short actuating lever and it works too on b models.
