Montesa

Hi All Getting my 349 frame powdercoated so will soon need new bush's. I know InMotion do the original ones but has anyone tried the nylon ones from France Trial Classic? http://www.francetri...arm-bushes.html

Hi all, this may be daft question but does anybody know if it's possible to fit a later clutch cover to a 71/72 Cota engine to have the clutch arm on top of the crankcase?

Folks my 1999/2000 315 is bogging really bad. Ticks over fine sets off in 1st fine but half revs its starts to bog out to near stalling. One of the lads thinks its the reed valve in the carb... its a dellorto phbh26 cs. Help much appreciated cheers

Anyone still alive on here that has any information on the clutch assembly? *******o clutch will not disingage ( stuck in gear) all gears selectable... Have soaked the basket in petrol and doesn't seem to be sticking.. really need an exploded diagram as I feel a crucial part maybe missing.. engine was rebuilt by someone else.. even the tiniest information would be great 👍

Hi, I have recently purchased an 81 349 and would like to know if anyone has experience with updating the swingarm to the later 84 349 MK/4 modifications with the shock mounts moved forward and swingarm angled. Also, with lowering the footrests. I have seen photos of 81 349s with these mods done and if anyone could give any dimensions or advice it would be appreciated. I always wanted to have an 81 and always planned to do the swingarm to those factory machine specs. Also, does anyone know if the later MK/4 swingarm would retrofit? I never heard whether or not the width at the pivot is the same for both.

Has anyone got any good info in the nine spring 242 clutch, the drawing is a little confusing, the 3mm spacer that sits in the castellated drive that goes into the back of the clutch looks to have another shim on the top of that, mine did not have one when I stripped it

Hi guys, Has anyone fitted a TRP rear shock to a 4rt? What are the base settings for the shock? Any recommended settings?

Hi all, has anyone fitted a decompressor to the Cota 248 ? It seems that the hole has never been drilled probably because the smaller bore didn´t leave enough room. A 348 head would do the job but reduce the compression so if anyone has previously tried this please say what it did to compression !

So, I'm replacing the kickstart gears on my newly purchased 304. I understand the problem that causes the failure is the weak "Z" shaped retainer that bends and allows the gears to misalign. Is there a good fix to the problem so it does not reoccur? I've seen a photo of a strap that crosses the gear to retain it but am uncertain if it would be a suitable fix. Would like to hear of other ways to prevent the gears from misaligning. Greg

Could somebody make me a paper pattern of a Cota 247 MK1 chain guard please? I'd like to make a new replica guard for mine. thanks Jerry

Sorry to be a pain guys but does anyone know what the piston clearance should be? I have just managed to get a 12 thou feeler guage down the side if the skirts and i am guessing that the clearance should be 5 or 6 thou? Does that sound about right?

Can anybody post up pictures of how the rubber front sprocket cover fits please. I have the cover, below but the fittings to attach it are missing. I can see from the instruction manual that there are some fittings, but the pictures are too small to see clearly. Does it push onto some studs? If you could include some pictures of the cover removed in order that I can see the fittings that would also be very useful. Thanks

Hi Can you change the crank seals on a '98 315 without splitting the cases??? Thanks

I am lucky enough to be picking up a Montesa 348 this weekend as I am moving over from mono's to good of twin shocks. The last Mont I had was a Cota 123 back in the early 80's when I rode school boy... I am hoping owners of 348's can educate me to the normal maintainance routines (eg oil chages, grades etc), frequency, things to keep an eye on or strange quirks. I thought I read somewhere that the gearbox has a separate oil fill to the clutch? its these bits of knowledge that will help..... thanks in advance Rob

Just serviced the swing arm, linkage and shock bearings on my RT260 - just greased and re-installed. The bit of slop in the travel that was there since new is still there and I’ve pin-pointed the top shock bearing as where there is play. Back in my MX days I remember this was often where play occurred. is it just normal to have a bit of play here?

I'm putting a new plug cap on, and the HT lead is looking a bit scabby (and has a suppressor) on what looks like an original coil - can I swap just the lead? Or do I just fit a new generic coil?

Afternoon, does know anyone where could i get hold of any GOOD condition indexing plungers for an 82 cota 248 Thanks all

Hello, new to this forum and have searched this subject but didn't find any info specific to my issue. Bike runs Ok on level and uphill but starves for fuel and quits on descents. It initially runs fine on downhill but after a few seconds runs out of fuel, pulling the choke lever brings it back to life. So, it looks to me like the float level is too low and as it runs downhill its burning off enough fuel to starve. I've pulled the carb and checked the float level. Spec is 23.5 to 24.5 mm. It's currently at 26.1 mm. So the difference between actual and high side of spec is about 1/8" (old school). Thinking this is likely the issue but wondering if there is anything else i…

I'm in need of a primary pinion gear for a Cota (white wonder) 349. This is the gear that is pressed onto the main shaft that meshes with the clutch basket gear. Does anyone know if other Cota models are the same? Any leads to finding this part is much appreciated. Thank you.

Hey. Sure this has been asked before. 260 vs 301 for novice rider? Im 3 months into trials and the beta 300 i bought is a real handful. A mate wanted it off me, so got my money back on it. I ride most weekends but just havnt hit it off with the beta. Ive been riding bikes for years, im just new to trials. I've always had 4 strokes in whatever sport ive ridden in and id like to try a 4rt before I have to buy another 2t. Cheers
