Happy with handling after rear wheel slip.
Took bike on a sunday afternoon trip off about 150km to test it through some curves.

On my way home,I opened throttle a bit and clutch starts to slip :shout:
Slowed down and open it again full throttle,slips again.
Ride home at 140km/h,very pissed and parked bike.

I have read the clutch files what to do to solve the problem.
My question: Is there any special tool that is needed to do clutch work?

Thanks
Hannes

I guess you already know but if you have changed motoroil lately its important that you use a motorcycle motor oil.If you use a synthetic based oil not made for motorcycle with clutch and gearbox bathing in the oil you might experience slipping clutch.I can recomend yamaha lube semisynth.

Pretty easy to do. Here is a good read. http://www.fjowners.com/index.php?topic=1808.0.  You don't even need to drain the oil if the bike is on it's side stand. You might consider having a new clutch cover gasket on hand along with the clutch disks and steels if you need them.

Thanks for the reply,but no,I didn't change oil after wheel swap.
Bike run Castrol 4T motorcycle oil in it.
It had slippich about 5000km back caused by wrong oil,but since I ran the Castrol,this is the first time.
If I accelerate normally,it is fine. It slip under hard acceleration

I had read this same thread this morning.
I just want to know if there is any special tools involved.
Pat answered me on that

If I get trouble a long the line,I will ask for help with it

If the engine has been worked on, ie stage 3 kit etc, you may need to add an additional clutch diaphragm spring.  I did this to me '85. the clutch pull is that much harder, I put the FJR Master cyclinder on it and it helped some, but still requires an added effort.

a new clutch spring should do the trick.  But while your in there.......upgrade.
