I'm looking for some advice, I have a montesa 315 r which I have used for the last year on my first year on a trials bike. It seems to need constant repairs so maybe its time for a newer bike. Have been looking for something around a year old but most seem to be 280-300 in size. Do you lot think it is ok for a relative novice to go to this size bike or should I stick to something smaller. Any pointers would be great as have not tried other brands so you lot are my only hope;-) the betas and shercos look popular but I do like the TRS but don't seem to find that many reviews for them. Thanks
put the clutch back together, new oil and adjusted the clutch lever. on the drive it seemed ok but need to see what happens when it gets warm. This means ill have to go and try again , thanks for the help guys
Sounds more like your lever isn’t returning all the way out and opening the bleed hole into the reservoir. So as the fluid heats up it pressurizes the system and gradually disengages the clutch.
Also could be debris blocking the bleed hole.
Thanks Dan, will check the hole and see if i can get a new plunger kit as i wonder if its just feeling its age. When i pull in the the lever the clutch disengages and engages when i let the clutch go, it just seems to struggle ir i put some load on it. is there a way to see if it is the plunger at the leaver or is it just trial and error ? sorry for all the questions its just a big learning curve for me as i cannot fix it with a hammer ;-)
According to my 315 manual,the clutch plates should be 2.65 minimum,and the springs 35.5 minimum,but what Dan says sounds very likely,seems strange that the clutch got that bad that quickly
Thanks Huski, do the friction plates measure 2.65 front to back or just the pad on one side. my overall thickness is 2.7 across the pad on both faces and 2 in-between the pads?
Need some help please guys. Was out today on some hills and bike was fine to start. But as the day went on the bike was reving at the tops of the hills but lacked drive. It got worse and worse as the day went on to the point I had a couple of tumbles as the bike could not make it to the top of the hills. As it’s in all gears I assume it’s the clutch friction plates that have gone? Have taken them out and look to have about 0.5mm on them. Is that worn out or should I be looking at something else . It’s a 2002 315r if that helps and here are some photos. Any advice would be appreciated ?
Have got a montesa 315 at the moment but a guy has a TRS 280 2016 for sale near me and am very tempted with an upgrade ;-) What are they like to ride if anyone has had a montesa before as dont do much but want to get back into it with a newer bike. Am i better spending a bit more on a TRS one as never looked at the TRS before but look great value for what you get when looking at others. Any advice would be great, thanks
Had a water pump shaft seal go so took off clutch and clutch housing( not basket) to get to seal. Have put back on and bike is in gear but I cannot now select any gears. Any ideas as to what I have done? Have taken clutch out but cannot undo basket bolt as think you need a special tool. Should I take off other side around gear selecter ?
Help again, sorry guys for my lack of maintenance skills? Have a 2002 315r and had a little water leak from what I thought was the water pump. I turns out it is leaking from a little hole (see photo) underneath the water pump. Have taken the cover off but cannot see how you get to it or should there just be a plug that goes in that has come out,
Some help please in case i am doing something wrong as have bleed brakes before but never a clutch. I have a 315r 2002 model, cover says dot4 fluid so think its the correct stuff.
Went to bleed clutch, took top cover off, attached pipe, Undid nipple, pumped leaver and redid nipple in- between but now have no resistance in lever at all. have taken out plunge pin in cylinder but looks ok. Does it just need bleeding again as it has air in it? and if so as it has no pressure in lever is the only way to do it with a vacuum pump. Am i missing someithing or is it just air?. help please.
I know its a bit of a numpty question but just checking before i become a numpty. i have a 315r 2002 and need to change to clutch fluid. It is dot 4 brake fluid in the clutch master cylinder as i know some other bikes have hydraulic fluid. ?
Great to meet you today and thanks for the insight as to what I have let myself in-for.Everyone was so friendly to, so just need to get bike sorted and will catch up on the next one I hope.
The only way you could tell for sure would be to measure the thickness of the disk with a set of calipers. I didn't have any different color or type of disks in my 4RT, but have had different thicknesses of the steal disks on my wife's Gas Gas and the glue issue on my daughters Beta 80.
Out with the measuring stick, more tools to buy, i love my local tool store , thanks ;-)
Thanks all, just cleaning and inspecting the plates have noticed the plate in first is different from the others, see photo, it's black in between the pads and on all the others it's a gold colour, do you think it's just because it's the first plate, all sizes look the same. Sorry for all the questions but have never taken a clutch apart before so learning something new every day ?
I would open it up and look at the friction plates and the clutch basket, if the clutch basket is in great shape and the clutch plates have plenty of life left in them then the beta clutch fix or new plates would sort the issue fine.
If when you check it out you see ware on the clutch basket your best fix would be to replace with new, however some people have carefully filed down the baskets and been able to get good results so that might be an option.
Good luck.
Thanks for all the replies,
have taken apart and basket looks ok along with the clutch plates. have ordered some dimpled metal plates (only £20) to see if it makes a difference. Looking at some info some people say plates should be fitted square side out some say round side out, do you think it makes any difference ?
I have a 315r and the clutch sticks if not used for a few days but frees itself after a little ride. Do i need to replace the clutch or is it just a strip down and adjust. How easy is it to put a new clutch in?
i can thoroughly recommend the Penkridge club, its very beginner friendly. The white routes are great for practice and the 50/50 is a good challenge to us wobblers!
Thanks bothfeetdown, will look forward to the next one and we can catch up and wobble together ;-)
Hi Yogibear, we have a trial tomorrow evening at Penkridge, details in the calendar. Also Saturday afternoon at Hobs Hole lane, Aldridge near Walsall. Then next Sunday at Howards Wood near Kingswinford on A449. Would be great if you came along to one, use it as practice and an experience if you like. If you make yourself known to me I'll give you a run down of whats going on etc. You'd be made very welcome
Sorry Hanks, cannot make tonight but will pop along as a spectator to the kingswinford one next sunday and say hello, thanks for the invite
Im ok with the basic stuff but could do with some fork seals and the clutch sticks a bit so someone who can put all the bits back together without any parts left over ;-)
Im new to trials bikes so need some help please. Have just bought my first trials bike, a Montesa 315r from around 2000 ish. My local bike shop will not do work on it so was wondering where is the best place for spares or a garage win the west midlands that can do some work on it please
Just to say hi as im new to trials bike but loving it so far. Have had road bikes but always fancied one since watching kick start as a kid. Found an old Montesa to get started on and going to try the courses at Kidderminster and Shatterford soon. If there is any other places close to Wolverhampton please let me know and any recommendations as to servicing as my local bike shop does not want to do my Montesa. Hope to catch up with some of you soon
