Clutch parts.

Here's a thought:

Remove the clutch handle and inspect for mechanical wear. An elongated pivot point hole will cause excessive handle travel. I've found that cheap, aftermarket handles wear quicker, too.

Went to Philip Island with my daughter yesterday for the GP Run,bike warmed up for 5 minutes prior setting off, got to the end of the street, turned and accelerated in 3rd, bugger me the clutch started to slip. marvellous, just what I wanted not to happen. Anyway we kept going cautiously to Cranbourne. Sat for 10 minutes before its time to go.  Had to sit in the traffic build up waiting. The FJ got the case of the crankys sitting in the traffic waiting. Had to shut down twice for the fear of overheating. After sitting for a prolonged time idling the  Idle revs started to increase by 500revs just idling. Knew it was getting hot, struggled to start again. Went to take off, the motor was pinging and rattling like crazy.  Went slowly for first 10 minutes just getting speed up and holding in the clutch to let the motor cool abit. Clutch never gave a moments problem all day after that except to say the "grab" on takeoff is all the way near fully released. beginning to trhink its more than a bleeding issue, particularly slipping.  One other thing noted, when it was getting hot the lever felt slightly less pressure. All in all 220km round trip went well. Its due for a service now so its inspection time I think.

Try flushing all the old fluid out of your clutch , from the master all the way thru the slave till you have nice fresh fluid .. moisture will build up in the system and expand to vapor when hot causing the clutch problems you speak of.

Is it necessary to replace the pressure plate when doing the clutch. I've been told no by one person however I thought I would check here.  What bits are recommended to be done.

Look this post over for guidance...

I used the above for reference when doing three clutches. If the spring has never been replaced before, I'd go ahead and replace. You're in there anyways when going through the discs, and replacing the spring will remove any doubt you may have had before. Use an FJR spring, their price is more reasonable.

Not that hard of a job at all. You don't even need to drain the oil, as I recall.

Don't forget, RPM is having a holiday sale and you can get 10% off all your clutch parts.

Question..... I have been trying to track down a clutch spring for the FJ. I read the FJR one fits? However what year is the required unit. Seems like there are none in Australia. The alternative is the Barnett one. The price is 4 times as much though. How much heavier is this compared to the FJR unit?    The  throw out bearing, do you use only the FJ one. Is it necessary to be changed? If I go with the Yamaha original or the FJR type it's a months wait. Back order. Clutch plates are no problem. Exyamaha and in stock to. Yay.

Not sure what what year FJR spring. Probably from a first or early second Gen one. I don't think Yamaha has changed them over the years. Use an online OEM parts source to check the OEM part number for the FJR over a few model years to confirm.

Never saw any need to replace any bearings in the three clutches that I've done. Don't spend the money, if not needed. Others may have their own opinions on it though.

From what I have seen in the http://www.fjowners.com/index.php?topic=1808.0 Guide, the aftermarket spring is inferior to the OEM ones.
