Montesa

Hi All Really quick question hopefully as I have to get my swingarm etc back on tonight if I can ready for the weekend. When I took the bearing seals out of the dogbone they all had the flat sides inwards ie next to the bearing and the lip/ open side facing out... I had to take the swingarm to have the linkage bearings cut out as they were totally collapsed and rusted in (there was nothing much left of the seals on the swingarm so I dont know which way around they were), now when I got the swingarm back (from an engineering place) the seals have been put flats out, I asked and he says thats how they are supposed to go. A little worried now as Ive put the seals back in …

Sorry if it has been asked before, but does anyone have the owners manual for an 04 (r4) Mont Cota 315r that I can download, or a link? If not I would like to change plug and oil before manual arrives from wherever dealer is getting it from. Though he is not a Montesa dealer and doesn't know specifics about the bike. So ............. plug gap???? and oil capacity/brand/quality? Hope you guys can help. Ged

I've been looking through the posts and now i'm a little confused! The bikes a 2002 montesa 315r, the clutch drags on it so how do I sort it, a full set of steel and cork plates or can I put in the correct oil(which is elf? where do I get it!?) and lightly roughen up the steel plates, or is there an aftermarket jobbie that will solve it forever? I'm a novice so the cluch drag is causing more issues than it would most! I just want to sort it but not waste money if it doesn't need to be spent!

I love my new 4rt but have recently had an issue and wanted to share my experience to hopefully save somebody else time and money. My bike started cutting out on me at a trial, sometimes I was riding between sections in 3rd and 4ty gear, sometimes I was in sections in 1st and 2nd gear, it sometimes would kick straight back up and sometimes it would take 10 kicks to get it going again. I rang the dealer “inch perfect trials” and explained the problem, it sounded to them as though it was the bank sensor so John talked me through how to by pass it. We hoped that sorted it but after going out to practice I soon realised it wasn’t that. I spoke again to…

Hi all,i have a 4rt and want to put her on a diet!!!! Anyone got any good tips to shed a few kilos of the old fat lass with out braking the bank??? Cheers Benz

How does mapping work, altering settings for different terrain. I have been told you can bluetooth message to bike to change it. Surely this is Bull****. Can someone explain how injection system works.

Putting the bike back together after having fork leg welded. All installed and forks are free to be pushed up and return well. When I put the wheel in, not simple as the wheel, brake plate and spacer are a tight fit, the forks are really hard to compress and when compressed do not return without pulling back on bars. What can I have done wrong?

Can any one tell me the spark plug hole is on the side I am sure and hole on top for decompression I am I right for monty 348

Ok..................Call me Stupid I've managed to elongate the holes on the hub of the back wheel I could do without buying a new wheel at the moment Any suggestions would be welcome I dont think it's possible just to buy just a hub........................is it? I was thinking about drilling it out larger and putting in a collar, is this a good idea Thanks.......................Stupid

What's the feeling so far on the fuel range?. Should Nevissport in Fort William start stocking up on Sigg bottles now?.

I'm just getting back into trials after a ten year lay off, I'm starting off with the same brand of bike which has saved me a bit of money as I had built up a spare parts stock. i have a sealed up one ltr of the very expensive HTX740 but it's ten years old. You you guys use it??

I have a 2010 Gas Gas 250, but starting her has been a problem due to a knee injury. First, it takes a good hard snap. Not so much of a problem, alone, but the kick lever hits the mount of the foot peg at the end of the throw, and being short throw it is hard for me to avoid bottoming out like this as it has to be kicked fast. So, I'm wondering about the 4RT. Does the lever hit against anything hard like this when you push it through? Do you have to give the lever a good hard snap? I would buy one if I knew about this one issue. But no dealer within hours and hours of me has one. Excited to hear replies.

To all 4RT owners. Is it just me or does anyone else agree that the rear brake pedal on the 4RT is made of pure CRAPPY alloy !!!! It seems the the slightest clip on a rock in a gulley and the shagging thing just falls asunder I'm now on my 3rd lever and I know some will say that if you rode round and over things you wouldn't brake em ! But hey we're not all Dougie Lampkin. With all the after market goodies for the Mont like Titanium pegs and hangers is there anyone making a decent Brake Pedal ? Calling Mr Ferretflasher , you seem to be the man in the know when it come to 4RT goodies is there any after market stuff out there ? Its just a bit of a pain the build qual…

Hi Guys I'm new to the forum, I've got a 2008 Repsol 4RT which has done very little from new. I bought it last year from a nice genuine guy in the North East and had a good ride before I agreed to buy it. Whipped off the front and back wheels, dropped the bars and put it in the back of the car for the uneventful journey home. When I got it home I had a couple of instances where during a drop it would die on me. So I did some research and removed and linked out the bank angle sensor. I tested it before removing it and the bike would shut off when leant over one side but not the other so it looks like it was faulty. Anyway, it never did run perfect despite th…

Hi everyone I'm beginning to wish I hadn't bought this montesa now, I've just rebuilt the carb after the animal that owned it previous had bodged just about everything, it now runs sweet but the engine sounds terrible, I've removed the flywheel cover and there is play in the main bearings. Can anyone give me any rough Gide line on what these engines cost to rebuild? I'm an engine reconditioned so the labour isn't an issue I've never bought 2 stroke engine parts before. And are the engine parts available, bearings gaskets piston kit etc Where's the best place to get the parts?

Hi Folks, I wondered if anyone else has had this problem and found a fix? I have a standard 2006 4rt, no silly ignition maps or owt like that, but the spark plug is getting sooted(spelling?) up something bad. It looks as tho it's running rich. The bike starts to run rough after a couple of events and tick over is noticeably lumpy and stalls more easily as time goes on. I run on 98 octane fuel (more often BP fuel) and have use both puterline and pj1 filter oil to coat the standard air filter. the next thing for me to try is 95 octane fuel. After that I'm at a slight loss as what to try next. cheers Leigh

Good fuel is very hard to come by in my area. Any easy way to reduce knocking? The only ones I can think of is adding base gaskets or retarding timing. Thanks.

I am trying to check the crank seals but the two screws on the small cover on the left in the picture have been butchered. Does anyone know what is behind that cover? I am guessing another bolt for the main cover at the very least. Thanks Arfur

Hi any ideas Early mk1 with alloy tank and separate alloy seat unit tank is shaped for a snug fit over the exhaust. Later alloy top yoke Replacement sm plastic mudguards ignore these cheers helm
