Montesa

After hearing a couple of other 315's today my '97 bike seems very loud indeed with a top end rattle. I suspect its going to need a new piston but when i looked at the base of the barrel instead of seeing A, B or C all I can see is O. So now I don't know what to do. Anybody come across this before? Pic attached of the barrel.

Has anyone been successful in getting a new 300RR insured for the road? The current insurance company I'm using for my 2015 260 doesn't recognise the 300, and so far neither do any of the others I've tried. Cheers

Howdy - I'm in a bit of a bind, though not a bad one to be in. Short form: I bought a 2005 Monty 4RT from a friend, and I loved it but didn't ride it enough. Tried to sell it, was going to get a crappy price for it, so my finacee ended up buying it on a bit of a lark. She hadn't ridden trials before, but now is totally into it, the backyard is a trials course, and ... you guessed it, now I'm in the market for another trials bike. So I am obviously leaning towards finding a good deal on a used 4RT (and am even playing with getting a new one up in Canada), but I was trying to get a sense of the other 4-strokes that have popped up since I got the Monty originally. Bet…

Now then, I want to ask the worldy wise about this Montesa clutch drag problem. It's doing my head in to be frank. No matter how warmed up the bike is, the drag is bad and keeps stopping the engine when i'm moving slow or stopped. Staring it is not funny any more. Does anyone have any sensible advice other than a new clutch kit? I also would like to ask, Is Castrol Driveline Sytnrax Universal 75W-90 any use for the clutch oil? I am not using it, just interested (bike still has the oil in that I bought it with in), but i have a lot of it spare, two gallons to be precise! So it would be nice to use it up... Look forward to any tips guys... many thanks Michael

Hi all, After moving away from home to live in Manchester I gave up trials and sold my bike It was my first trails bike and was a 2005 GasGas 280 TXT Pro, and i found it hard to give up.....that was in 2009 Im now living in my local area again (west yorkshire) with a mortgage! and wanted a cheap hobby and to get back in touch with the local trials club. So on an impulse buy i've bought a cheap Montesa 315r. Now I thought i'd stick a post up on here and ask if anyone know of any Montesa specific related issues that i should watch out for? i've already done alot of searching on the forum and found some great info, http://www.apexmotosports.com/content/montesa/315-te…

Hi all. Just wondering if any of you still own a Montesa Cota 330 ? Used to be a few on the forum at one time.. Just doing a couple of wee service jobs on mine as its been stored for a few years !!. Cheers Sandy

This may seem a stupid question but I have a 1976 Cota 247 UKR which I have owned from new. It hasn't been used or over 20 years and I want to tidy it up and see if it will start assuming the seals are OK. I know I need to clean out the carb etc but is it ok to run on unleaded fuel from the local garage, what oil should I be using and what ratio petrol/oil mix please. I know that with classic cars there is also a problem with modern fuels destroying the seals in the carburettor. Is this likely to be a problem and if so is there a new seal kit that I can buy which is suitable for unleaded fuels. Thanks

Whats the best result for the 4rt so far? Now James Lampkin has chosen the beta to ride rather than the montesa to mind is there anyone any good left on one? Who are Sandifords sponsoring and how did they do at the first national of the year the Vic Britton?

Just drained this out of my Cota 349 as mentioned in a previous post. Should I pull the clutch cover off or just wash it out, refill and see? Cheers.

well, I have made a photo of the Montesa 03mod, I think that it's way nicer to look at then the original mont. and i have done the same thing whit my rear fender.. and it looks great.. the whole bike looks smaller.. so what do you guy's think??

I found this bike 2 years ago. I like big alloy frame bikes and the 311 is an interesting model. Not a design masterpiece , not fashion bike, but cool. The bike is in good condition. Let start by the wheels. Cleaning everything, paint job, new bearings (I love working on wheels) I have a brand new platics set. The engine need paint job (main bearings, seals, maybe piston will be replaced) Marzocchi shock need full service. Every rubber parts will be replaced as usual on +20yo bikes ... (carburator, fork, hose, seals, grips, tyres... ) Calipers and master cylinder will be restored. …

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

Viva Montesa no More

After a few attempts at getting up a snotty climb, having my bike on its side more often that not it decided to die on me. No attempt at kicking it off would start it. Took the plug out no spark, tried a new plug no spark. After a while a realised the throttle seemed to have far too much play on it. Tomorrow night I'm going to have a look at the throttle body and where the throttle cable fits, but thought first I'd see if anyone anyone could point me in the right direction. The bikes a Repsol. Thanks CK

Hi All - me again im going to get a new chain. Cant really afford to splash out on theRenthal RI so i'm down to the D.I.D 520 Standard Roller Chain or the Regina 520 Ta Dan

Hi, I've recently bought a 2015 4rt which I'm having a problem starting when cold, once it's warm it seems to start no problem but seems to tick over quite high, could anyone give me any advice on this problem and also tell me what RPM it should run at? Thanks

I've got a 2015 Montesa 4rt that I bought new , it's been maintained above and beyond, but I've recently been suffering from what appears to be a rich mixture. I replaced the plug four events ago for an NGK iridium one which has become sooty, as did the last one. It also smells rich when it's on tick over and uses more fuel than other riders that I ride with that have similar bikes. The bike rides and performs well and I assumed with fuel injection that there would be no mixture issues. The air filter is a TwinAir and it's cleaned after each event It also seemed to boil the fuel, for want of a better phrase, at last weekends event. The bike still …

After a few questions on here I eventually found a bike, so I'm now the happy owner of a 2010 4RT. But immediately there's more questions:- First of all, does anyone know from where I can obtain some frame protectors in PLAIN black? All the ones I can find are carbon look and I'd rather have just plain black.

Hi guys just wondering what you think the best/essential mods are to a 2015 repsol 4rt? Apologies if something similar has been asked before!

Does anyone know the performance difference and mapping availability between these kits?Is anyone using any of the above ?
