masso Posted September 25, 2006 Report Share Posted September 25, 2006 well, I'm surprized you are not inundated with replies! the clutch was the first thing we worked on... mine was terrible! for a quick fix..try automatic transmission fluid that works well, or use the actual oil recommended in manual ... everything else ain't no good then you get the clutch leaver and reservoir from the 315....it works better then you get aset of mitani clutch plates...........by this time it should be working well why they couldn't fix this on the world's most expensive , most hi-tech machine is beyond me .......................................masso Quote Link to comment Share on other sites More sharing options...
dixie Posted September 25, 2006 Report Share Posted September 25, 2006 masso they did , have you tried an 06 monty? that seems to be the only real difference between the 05 06 models. as for no replies we were all in bed its nite time over here i have used putoline 75 weight oil and it works fine in my monty.only thing is sometimes it howels like the 315 used to but this just maybe cos i use it harder now . good luck Quote Link to comment Share on other sites More sharing options...
mad4it Posted September 25, 2006 Report Share Posted September 25, 2006 two of my frirends run 4rt't and both of them suffer from nearly being impossible to get into neautral when running. this is due to clutch drag ! motul 300 v in g/box works well but they still do it. Montesa 315's used to suffer the same fate till you fitted honda cr 250 friction plates. Quote Link to comment Share on other sites More sharing options...
dixie Posted October 9, 2006 Report Share Posted October 9, 2006 dont worry if it is hard to get into neutral worry if it wont stay in gear 1 Quote Link to comment Share on other sites More sharing options...
grouse Posted October 9, 2006 Report Share Posted October 9, 2006 USE THE RECOMMENDED ELF OIL! MY 06 4RT STARTS IN GEAR,FINDS NEUTRAL OK AND DOES NOT DRAG THE CLUTCH AT ALL. IT MIGHT BE EXPENSIVE BUT THINK OF ALL THAT MONEY YOU ARE SAVING ON TWO STROKE. Quote Link to comment Share on other sites More sharing options...
fantic303 Posted October 9, 2006 Report Share Posted October 9, 2006 (edited) I have the same problem with mine 05 4RT. But if the 06 4RT does have the problem with the draggy clutch, what is the difference between the clutch from a 05 4RT and a 06 4RT. Picture of mine home made sump guard I have the same problem with mine 05 4RT. But if the 06 4RT does have the problem with the draggy clutch, what is the difference between the clutch from a 05 4RT and a 06 4RT. Picture of mine home made sump guard it is longer (protection for the link system) and gives more protection to the waterpump and flywheel.

I've seen this a few times on various treads. I know it holds more fluid however the plunger diameter/bore is the same so it won't be causing anymore pressure than the standard AJP one will. I just can't see how it will make a difference. I also read a thread on another forum called "improving the 2005 Montesa 4rt" and they fitted the 315 master cylinder then went on to say it was an unnecessary mod as it made no difference at all. No having a go I'd just like to know your opinion on the subject. Cheers, Gaz. Quote Link to comment Share on other sites More sharing options...

Not all of them have the same lever or the same pivot point location, this could change the stroke and leverage to give it just a touch more throw at the slave side. Best guess but at least its one possible explanation. Quote Link to comment Share on other sites More sharing options...
