Montesa

Hi does anybody know were I can get a Grimeca front brake master cylinder repair kit for a Montesa 315 2001.Ive already tried Sandifords and splat shop

I rode a bike with the v Mar linkage plates and I really liked what it did for the handling. I did some internet research and see some csp, future and also h+d's own version of the vmar ones. Has anyone compared all 4? Are they dimensionally the same? Same materials? Then for footpeg holders, are the csp and future trial ones dimensionally the same or does one position the pegs further back? I've got a 2017 300rr. Thanks, Jon

Maybe of some help to someone https://www.motorcycle-manual.com/montesa/

Hi, have started to rebuild a 1974 123. Stripped her down, now sending frame for powder coating. Cleaning the front and rear shocks, all looking good so far. Will post pics as I progress. Thanks Mike

Hi guys, want some new shocks for my 247C Can anyone provide what length and mounting dimensions I require? Many thanks for your help.

Ok guys and gals, who has tried the new Repsol transmission oil in their Montesa's. have tried to buy more Elf Htx hear in Australia and told unavailable now ?

Having no experience on any of the above models, those who do own and ride them, can you give me your findings .....Both good and no so. Looking to buy either, so interested in 'real world' views. Cheers Andy

I am currently rebuilding the front forks to my Montesa 248 and would like some advice regarding the grade of oil required and how much oil goes in each leg. Thanks

Hi I am looking for a crankshaft for a very early Mk 1 247 cota (1969) as the one i have is cracked any info welcome. Thank you Ian

As in title, after last long trial, noticed I had lost a rear sprocket bolt, in its escape it has worn the swinging arm . It has cut a slot in the flat plate area, approx 50% through...... My thinking is to get it aluminium welded and dressed back, anyone had similar?..... what was your action? any idea on what grade aluminium is used on the swinging arm.? thanks (it’s a Montesa 4 ride )

Hi there just wondered if anyone has experienced a problem like I’m having. my 15 repsol starts fine and runs away fine, but after a bit it starts dropping the engine speed on shutting off the throttle and it goes below idle speed and stalls. It will immediately start again and idle away fine, but drive the bike again and it will drop the idle speed and stall. So it’s happy idling from start up, but drops off from shuttling the throttle off. Seems to be once it’s warm. While running it takes full throttle and seems fine, but once shutting off it will stall. I have cleaned the throttle body main venturi butterfly passage and the air passage that is in use…

Hi , Looking to replace the chain on my 4rt as its seen better days and nearly at the end of its adjustment with the allen bolts still in forward holes for snail adjusters in swingarm. It has been running out of adjustment and has worn the chain tensioner block so time for a new block and a new chain, sprockets are good. Can anyone recommend a chain or tell me what link the chain should be ? I have 10/41 gearing so not sure if its stock or not , something tells me it should be 100 link ? Finally , a really schoolboy question and almost embarrassed to ask , can people tell me the best way to check the chain adjustment ? the manual …

Hi all! My first post.......I have a bad fuel injector after drowning the bike in a river crossing. The parts fiche shows the whole fuel injector assembly, not just the injector. The injector looks pretty generic but I can't find a replacement anywhere. The number on the injector is FE26 BBR. Any ideas?? Thanks!

Not strictly a Montesa question, but I’m running a Showa 315 front end in my RTL so I can have some affordable front pads. I noticed when I washed the bike yesterday that the yoke / forks seem to be slightly raked compared to the frame header; i.e. not parallel. So I compared to my sons Scorpa 20 and my 2015 4RT which seems to have parellel forks to yokes. Which I assume mean parellel yokes / fork clamps. Do later Montesa’s have parellel yokes / fork clamps? If so does anyone know from what year 315? jstbwondering if it’s a function of the frame header rather than the fork yokes.

Hi im trying without success to back bleed the front brake on my montesa 315 .Ive pushed the pistons right back and the bleed nipple is a 1/4 turn open yet no matter how hard I squeeze the syringe nothings happening . Any advice will be much appreciated .

have checked the 2005 threads on the above . my 2008 bike is no different. can you tell me if the 315 master cylinder is still the way to go? i assume my bike is fitted with a standard m/c as it is a mirror of the brake cylinder. its driving me nut's in tight turns with reverse camber as its almost impossible to apply power. just too on and off. many thanks in advance.
