July 2, 201016 yr Hi all, bought a mont 315 r that hadnt been used for 1 and half years, just been stood, anyways after giving it a good ride, i replaced the gearbox oil. Seems loads better now, but when the engine is at low revs, with the clutch in, it seems to drag a little and bike keeps moving, until i give it a good rev. any ideas please?? i have only been riding around in the garden since changing the oil, so wondering if it just needs a good run in? cheers
July 2, 201016 yr What oil did you use - Mont clutch very sensitive to oil type. Search forums for comments but the expensive elf oil or atf seem best options
July 3, 201016 yr Author cheers , not sure what it is just somethin i was recomended so il have a look , ta
July 3, 201016 yr If you take the clutch apart check the 'fingers' of the clutch basket, mine had worn notches down them. A gentle file should be all that's needed. Also check the steel plates for straightness
July 12, 201016 yr Author drained all oil again from the clutch. Took clutch apart and looks fine, then i put it back together and put ATF in, but it still drags when idleing and crawls forward..... an ideas please
July 12, 201016 yr use pj1 clutch tuner the ultra light stuff and get a master cylander overhaul kit about 10 pounds or so for one of them. it will still drag a little tho untill you have moved off and stoped some of them just do that but if you use that oil and do your master cylander that will help.
July 27, 201016 yr drained all oil again from the clutch. Took clutch apart and looks fine, then i put it back together and put ATF in, but it still drags when idleing and crawls forward..... an ideas please Clutch drag was the norm for the 315. As stated, it is very sensative to the oil used. The ELF oil that the factory recommends is absolutely the way to go. As an alternative, SureFlex made a clutch kit that dramatically improved the bike. Haven't looked in forever, but they are likely still available.

What oil did the previous owner use? Did he switch brands often? Clutch plates can swell up and drag when subjected to a cocktail of different oils. At this point for you just changing oils may not be enough. Try to rough up the metal discs with 300 paper.Metal discs that have worn smooth can cause drag. If all else fails than new plates are the answer. There are several options for replacement: Standard plates work well if you use the ELF oil, Honda CR 250 cork plates work well also SureFlex is good. Oils: ELF HTX 740 is the best. It may cost more initially but you can go longer between changes so the cost ends up the same as others. PJ1 Clutch Tuner works well but seems to degrade quickly requiring frequent changes. ATF is cheap but clutch actions is grabby. Edited July 28, 201016 yr by Martin Belair
