Is there something to the report from my buddy that his clutch engages too far out from the bar and will not adjust properly. He tells me that the screw has no effect?

Someone tell me whats up so I can let him know!

Not sure if this is the right advise, try releasing a little fluid from system it may help. Don't hold me to this advise thou!

Remove the clutch lever, then the actuator from the master cylinder, cut or grind .1 in (approx 2.5 mm), grind round and polish, works perfectly!

Forget using the standard clutch master cylinder. Remove it and replace it with a clutch master cylinder from a 315. No other modification needed, simply bolt it on and use, it makes the 4RT clutch just like a 315 clutch. Just about all the bikes in the UK that I come across have this modification on, it's not expensive, a complete clutch master cylinder with lever in the UK is about £37 - that's about the price of tank of fuel for my car for our American friends.

Hi Hillary
Can you be more specific as too what you mean by the 315r master cyl making it work better

my 4rt seems hard to slip the clutch as it tends to be grabby changing to silkolene trans oil has helped but not totally satisfied yet

I have no problems with the engagement point since I modified the plunger pin day one

thanks for your help

Don't know why 315 master cylinder works better, it's bigger, so has more fluid and maybe has more leverage, but it's the simple answer.
