Montesa

Does anyone know an easy way to soften a 315r till i get used to riding (first season).cheers

I need to change the pads on the front of my 4rt an the 2 bolts holding the caliper in place will not come out ....seized, and the allen heads are now pretty stripped. I have read that this is a common problem and I am sure I have seen some replacement bolts made of titanium or something. Can anyone help??

HI... I HAVE A SMALL PROBLEM... I HAVE BEEN FOR A NOSY AT TWO BIKES; A 2000 MONTESA 315R, AND A 1999 BETA TECHNO DOUGIE LAMPKIN REP. THE MONT IS

does anyone have any advice on cleaning std 4rt clutch plates,also after returning rear shocker to factory setting.cheers.

Hi, again one of these about to buy a Montesa threads. There are two 2001 models I am looking at. Both are in decent condition and quite reasonably priced. I was just looking at the images of them and noticed this. Can you explain what is going on here, the rear tire looks like its is not straight? Is this a problem or just something I could easily straighten? Thanks!

Does anyone know the website for TRW Montesa?

Been looking at this topic and have started wondering if this has anything to do with my bike stalling.I have got to thinking that my bike has got harder to kick over than when it was new.It is about ten months old and i have nether checked the valves,does anyone think this could be a problem with the valves.Although the bike is hard to kick over it start first kick usually.

Anyone out there know if an iridium plug is available for a 315r '03? cheers

Hi, Does anyone know where in the UK that might stock or be able to order the 2007 RTL250F plastics. They are similar to the Fujigas Rep ones in white. Just fancy having something a bit different. I appreciate that Andy has understandably clamped down on forum advertising so if you don't feel able to post a reply then please PM me. Cheers

Is there any one that can help I have got an 05 4rt that destroys spark plugs in two hours riding and starts miss firing back firing you name it its doing it the plug is black in soot .Each time I put a new plug in it lasts for two hours agian. I put a new coil and lead and cap but still the same problem.

Does anyone make an aftermarket muffler for the 315R?

I bought the 315r Mitani clutch pack from lewisport and I can't get a reply back on how to install them into a 315r. There are 2 light discs and 4 dark cork, what bloody order do I put these things in?????? Jason H

Hello All, I brought my 4rt in for a routine valve adjustment to a shop I'd never used before. The mechanic is definitely competent, but totally unfamiliar with 4rt's. I left the manual for him to check out the specs, etc. When I picked up the bike, he said the exhaust valves were slightly tight, and he adjusted them accordingly. Tonight I got a chance to ride the bike. It starts easily and idles well, but when I whack the throttle open it just coughs and there is nothing. Is there potentially something he overlooked or a common error that he might have made? Thanks in advance for your help. Regards, Wardo

Dads wondering what plug type to use in his 06 4rt? the plug is always very black as if the bikes rich or do you think a different plug is needed. I think the standard was a 6 but he has been using a 5 recently but its not made much difference. May just be this is how they all run though? Thanks for any help/info Just

Does the 07 feel different then the 06 with the cam change!and does it start any better?

After 15 years of not riding I have taken the plunge and bought a 2005 4RT to get me back into it. First impressions are snappy off idle power (plenty off it compared to my old TL125) and noise! Sure is loud! Has the end cap but will have to pull off the front pipe to see which other restricters it has. It will probably have them as at a trial last week, there were 4RTs that were much louder. Have read all the replies in this forum but seems no one has a solution yet (WES silencer mentioned but it needs to be significantly better for me to buy one). Will probably get a slow action throttle and possibly a PTB in the future. Has a 6 bolt 42 tooth worn rear sprock…

Does anybody know what the squish should be for a 315 (gap between top of piston and bottom of head at TDC)

Right then all you 4rt riders which throttle body would you recommend to use? the 2 stage switch type (soft/mental) or the full programable one you can alter yourself or buy programmes for? if the programable one is better whick map would you recommend? Doing this post for Dad as hes keen on getting one of the units but has no real clue which is the better. Any comments much appreciated Thanks Just

Following on from the error in the manual on dip stick screwed in or out when checking the engine oil level. I'm about to check the valve clearance for the first time. The manual states "aline the T mark on the flywheel with the index mark on the left crankcase cover" But I've come across this service bulletin click here Which one is right??

Has anyone got any suggestions on what maps I should be using in my 2 stage PTB for the SSDT? Thanks
