Montesa

Hi guys, anyone recommend a decent hour /tachometer for 4rt, to check tickover and hours of use, thanks

Hello, New to the site and my fairly recently acquired 1976 Montesa cota 348 MRR. I am having problems selecting the gears. With the bike running and moving, going through the gearbox sequence from 1st to 6th gear is quite difficult with a very stiff selector lever, gears not engaging correctly and quite a few neutrals in between. Changing back down from 6th to 1st is better but probably because it is easier to apply downwards pressure on the lever. All the gears are there, it is just difficult getting them. I have tried adjusting the concentric nut on the selector mechanism until I have got the best lever movement possible but it is still problematic. The …

Continuing on the 349 ‘81 thread (white wonder I’ve been advised) here’s one for the aficionado’s out there who know more about these the than I do (which to be honest isn’t difficult😜). the frame is stripped & now at the powdercoaters waiting for a little tlc. Although she’s been clearly neglected the latter part of her life, there seems no lasting damage on the frame nor the swinging arm. I did notice there’s no evidence that she’s ever been painted, the frame & swinging arm are simply pure surface rust.......but.......there’s a hint of either silver paint & definitely a hint of chrome, albeit just a morsel here & there. so, ‘those who know more …

349 ‘81 bought as a heap & someone had already been digging around & started to remove certain pieces into a box, hence I’m unsure of where things go & how! This model has an alloy tank with a fibreglass cover that simply straddles the alloy tank........silly question time, how does the alloy tank remain fixed? The tank straddles the main crossbar of the frame & the tank cover sits on top of the tank......is that enough to secure the tank? There are no fittings on the alloy tank so I guess it just sits there? Obviously the tank will have bits of an old inner tube where it meets the frame [about to be powder coated] rather than scratch the new pai…

In the process of painting my '84 349 tank cover, look carefully at the front where it secures to the frame. On all the photo's I've looked at, the tanks/covers are held in with a bolt that goes through the tank itself, on mine, it looks like the tank simply 'hooks' over mounting lugs. It's a fibreglass tank cover that sits over an alloy tank. I did think has someone broken the front of the tank & merely 'chopped' it about, but the curves on the top right of the photo look standard. Any thoughts much appreciated.

Hi all, is there anybody that provides an alloy tank for the Cota 21M that will sit under the original tank / seat unit with the old tank base cut away? Or can anyone suggest a company that might make one.

Newbie to this forum looking for help thinking of buying 4ride for casual green laning. reviews tell of the gear selector being a long way from the footrest but that there is a gear selector you can get to bring it back to the 'normal riding position' is this true and will it be in a position like any other trail bike? and is it expensive thanks in advance

Can anyone help me with the correct way to assembly and setting up of my cota 310 kickstart shaft. I have fitted a new spring and now cannot get the mechanism to work. How do I set up the cam type gear and do I tension the spring after fitting the cover? Any photos/ diagrams would be appreciated. The only time it worked properly there was a constant ticking of a gear not disengaging properly.

I haven't written anything here in years but now I have information that I think some will be interested in. This will be quite technical so bear with me. I am writing this from the standpoint that you know how the use the HRC software to change the mapping in the ECU. More info to come. Background Almost a year ago now I came across some software developed to flash the ECU of different Honda motorcycles. Being an engineer I started to wonder if it would be possible to use on the 4rt. I have always been annoyed that the HRC software only lets you modify fuel and spark advance in relation to some maps that are unknown. After some research I found that the flash sof…

Thanks to all who helped with my last post. Can anyone tell me how much gear oil I should be putting in a 1982 Montesa Honda 123 and what 2 stroke mix ratio it runs on. many thabks Mike

'84 242 with 304 clutch & gearbox, oil looks nice & red but the time will come when I need to change it.....so....what's the consensus of opinion? ATF [Motul ATF V1] ATF in general [any favourites?] 10w30 light gear oil [again, any favourites?] ELF HTX 740 Mineral.......semi-synthetic..........fully synthetic? Appreciate any thoughts & views on this.

I have x2 247 Cotas that I'm restoring. 1 has the original glass fibre inbuilt tanks and the other an aluminium tank that sits on the frame spine with the fibreglass tank internals removed. What is the UK situation with running fibreglass fuel tanks as I believe back in the day they were banned hence why some bikes have ally ones? Thanks Folks

Folks. What is the cylindrical chamber I can see on some 247 pictures mounted on top of the rear engine mount? Thanks

Hi, I recently bought a Montesa 200 frame for a project and now that i look at it closely i am not sure if one of the downtubes is bent or it is meant to have a kink in it to allow exhaust routing or similar, its the right hand tube, Could any with more knowledge offer some advice, cheers Ian

Hello All, 2011 4RT 4 months into my ownership had burnt out a fan motor (and in the process melting the central boss of the plastic fan itself). I got a new fan motor (and plastic fan blade) fit them both (spinning freely and running as it should seemingly) but after approx 15 hours riding later the new fan motor has... burnt out melting the fan centre again! Surely this cant just be bad luck can it? Why might that happen twice ? Its not catching - so I doubt thats the problem. So far as I could tell the fan would run perhaps 5 mins after a cold start and would run and stop periodically as needed. Might it be a relay or voltage regulator thing. …

Hi there. I'm coming back to trials after a 6 year break. Cannot believe the cost of used bikes now. What happened? I've had four stroke trials bikes before as well as two and am considering a new 2020 Montesa 260rt. Mainly due to the Honda 6.9% interest rate which would suit me. It's £5999. Dealer says he will throw in registration and road tax. Delivery will be £20. Couple of questions. 1. If I wait a few months will Montesa release a 2021 version of this and any left over new 2020 bikes drop in price? I think the Honda 6.9% offer ends in may. 2. Shall I try and strike a better deal? I'm not part exchanging anything. I stupidly gave away all my bits with…

Hello everyone does anyone know where i could get a set of points in the UK for my montesa cota 200 . Thanks in advance Richard.

Can anyone help with the standard sprockets on the 247 Cota please? I'm using a 520 chain if that has any bearing on things..
