Montesa

hi all my mate bought the above bike i said i would help him give it a service as it his first bike problem is i own a beta and not sure of thing like changing the oil as it looks like a different method to the beta also how much do you put in as his clutch is dragging quite badly any other advice for servicing would be great eg fuel mix and such like cheers hamster

These bikes are the boy's ... listen to this double blip ! ... nice ......or tryMy Webpage

Anyone experienced vibration on a 315R? Happens in any gear, when revs get up while travelling between sections. I've check all engine mounting bolts & they seem tight. or it this a normal 315R feeling (our beta is very smooth with no vibe at revs) TIA for any ideas / thought on this.

what is the best gearing for a 315 Cheers Ryan

http://www.trialscentral.com/classifieds/d...php?siteid=1444 I wonder what this makes it go like? Looks a bigger bore system to me.

Any one seen or think it would look good A Montesa 315r red one 2001,02, or 03 With repsol rims on it James

just wonderin if any of you guys have used the jitsie rear linkage??i assume it changes the geometry of the setup slightly to help with jap zaps etc but would it be 40 quid well spent?

Hi, Looking for a bit advice, not a clean tick over on my 4RT, its wandering .. high then low.. What could it be ? Havent tried a new plug yet , but I've heard the gap on the plug should be closed up ? can anyone confirm ?. It's fine once above tick over and revs normally ? Does having the rear baffel out make any difference ?

Hi everyone. I desparately need some help before a trip is needed to the dealer.My mate has just bought an 05 4rt and took it for its first outing today. Kicked over first time at the start, rode it fine for about half an hour, stopped for 5 mins for a drink and now it just will not start. We have now been trying for a good few hours to get it going but it does not want to know. I have taken the plug out and it is very slightly wet which I expected with kicking it over for so long without it firing, but it is in good nick with a good spark. I have cleaned and reseated all the connectors I can see but I dont know where to start now as I know nothing about 4 stoke bikes. c…

My 315R will not turn off if the engine is revving at high rpm with the kill switch. It works OK at lower rpms. Any ideas? Thanks.

ANYONE KNOW WERE TO PURCHASE THE ECU CABLE AND PROGRAM TO RE-MAP THE 4RT

Keeping a clean airbox/carb! I use filter oil, grease around the the lip of the filter, grease even at the mouth of the airbox lid! But I continue to get dirt in the carb, I always check the boots between carb, cylinder and box to make sure seal is tight! Air box has no cracks seems good. I feel like I take all the proper steps in preparing a clean air flow on my 2003 Mont! How often do you guys replace your filters, buy new ones? sam

I have new rear plastic for my 03 315 but I want to "fix up" the old one a bit to use for practice. I could prob make it look OK using silver or black , but wondered if anyone knows a close match to the red. eg FORD XYZ red which I can buy at an Autoparts store in a spray can.

My 4rt came with a check valve installed in the fuel cap breather vent hose. The check valve allows air to escape from the fuel tank. I think this is upside down. Isn't the breather supposed to let air into the tank, or is there something special about the whole fuel injection set up?

would spending the money to replace / repair be worth it

i recently found the original steering lock thing that was supplied with the bike,and thought i might aswell use it, but i cant for the life of me work out where it attaches !!i think im just being dumb but help would be appreciated

I recently got a brand new 2005 Montesa 4RT. It could be around 5 Months since it leave the factory and shipped to my country Indonesia. I Just started it (following all Manual procdure)and it run at idle perfectly. The problem is, it run very poorly when the accelerator is pulled . It feels like not enough fuel, (or too much fuel ? ). The manual says that it might be the TPS (throttle position sensor) is shorted out. As you know the TPS is part of the ECU.So I cant check any wiring. Anything else shall I check ?, Vaccum line clogged ?, Injector dirty ?. I have not opened anything yet. Thanks

Question probably been asked before but does anyone know where a 4RT workshop manual or parts list with diagrams is available on line. Thanks

As it is almost finished, I thought that i had better post a picture or two before it gets Scratched!!

I am restoring a pair of Montesas and need some help with the jetting. I have new Mikuni VM26 carbs for each and have been given jetting for both from a couple of sources here in the US (expat Yorkshireman), but the 348 which is finished would not pull the skin of a rice pudding. Any one have any experience of putting Mikunis on the 348/349. Thank You.
