Dads off line for now, kids messed up the computer . The clutch on his 4rt was perfect for the first few weeks but is now next to impossible to start the bike in gear because it is pulling? Hes been using the Elf oil and has bled the system through so it not a cable/cylinder problem thats causing it. Has anyone had any problems like this and what can be done mod wise to sort it out.
He does have Hyspin AWS32 high performance mineral hydraulic oil which is very thin like the Elf, anyone tried it? or is there a better oil to stop the dragging.

Many thanks for any comments or answers

I have 05 4rt with 06 clutch. Use ATF, starts 90% of the time when in gear, 100% when warm. Takes 5 sec to disengage when cold. But pepole say elf is best????

I used castrol SLX 0w40 in gearbox and engine- it is a first rate oil- clutch was excellent.

Munch,
Did you just change the metal plates or did you fit Mitani friction plates too?
I'm thinking of fitting Mitanis on my 05 bike but if it's worth changing the metal plates I'd rather do it all at once.
What metal plates did you fit?

I have recently replaced the std steel plates with Jitsie steel plates and and ATF oil with the recommended HTX740 oil. I feel after about 10 hours of riding that the clutch action have been improved. I don´t know if it was the plates or the oil or both that made it but it was well worth the money as I only I payed around 5EUR each for the plates and 25EUR for two litres of the ELF oil.
Jitsie plates

as above , used the jitsie plates.
mitani are good too. ive fitted both.

I had the original steel plates replaced with the jitsie plates, but no result the clutch keeps on dragging even with the recommend HTX740 oil. Now that i have replace the friction plates for new ones the clutch is terrific.
The motor starts in gear and its easy the get it in the free.
I think that the problem is that the friction plates become too smooth so that they stick together.
Changes with other or larger master brake cilinder will not have result.
