Brilliant answer. Many thanks. So it is the right bearings with the wrong collars.

Many thanks for the answer. Just got to work out now whether I've got the wrong bearing or spacers. I'm geussing it's the spacers as I'm sure the bearing would come to the factory pre fitted.

As my previous threads have said I've bought an unused 2020 260 mont. It is brand new and unused. Oddly I noticed play in the top shock bearing. I tried to tighten up the bolt but it was tight enough. I took off the shock and it appears the bushes do not sit properly in the spherical bearing. I'm convinced either the factory has fitted the wrong bearing to the correct bushes or vice versa. After noticing that my chain tensioner block had been fitted upside down nothing would suprise me. Aren't dealers supposed to pdi bikes ? Im wondering if maybe the factory fitted showa bushes or bearings onto Olle bearings or bushes. They would have had both in the factory for the different spec bikes. If you look at the photos of both bushes they look pretty identical but I'm not sure if they are incompatible. They certainly have different prices so maybe they are. Interestingly the shock bolt was one of the few bolts that didn't have the inspection paint blob on from the factory. I've just taken my shock up to my local trials shop so they can get to the bottom of it and save me ordering parts unnecessarily.

My mate who had four 4rts in a row said to fit a fast throttle too. I may try the one off my beta and see how it rides.

Here is a photo of the switch mounted on a coolant hose. I just wonder if the heat will damage the switch or cause issues

Could anybody tell me what map 1 and map 2 are best suited for. I've ridden both modes on the same section and can't notice any difference. On my Beta 300 2t the map switching positions are very noticeable on how the bike performs. Also where have people repositioned this switch? I seem to constantly knock it into map 2. I think my lanyard is hitting it. I saw one mont where the map switch was neatly mounted on the radiator hose by the kickstart tip

I think trials bikes are about 114cm high but if I was you, get your vans garage built big enough to fit a Motocross or enduro bike instead. They are much taller than trials bikes but many more people do Motocross/ enduro. When you come to sell the van it will appeal to a far bigger audience. I'm speaking from harsh experience having just sold my last race van which could only accommodate a trials bike. Worth considering.

Yes definitely agree. When I fitted the swingarm, frame and fork protectors I removed all spindles and greased. They certainly weren't greased to the level I would do. I hate doing linkages but I thing it would be a job worth doing sooner rather than later. Thanks

Yep thought so. Thanks. Glad I only did one ride on it like that. Will go over every nut and bolt tomorrow.

I've noticed that my Montesa 4rt which is new to me has a slack chain. Bike is 2020 but brand-new as previous owner had it as an ornament. I noticed a slight clinking noise when oiling the chain on the paddock stand before my first ride on fri. But on closer inspection I'm wondering is my chain tensioner block upside down. The chain must be making the clinking noise when it catches the frame on the horizontal bottom tube under the swingarm pivot bolt. With the tensioner block in the opposite direction facing up it would raise the height of the chain and solve this issue. Am I right in thinking this is the wrong way round? Surely the factory hasn't fitted it upside down ? Bike was brand-new and unridden when I got my hands on it.

How does this thing pop out for cleaning? My Beta ones just popped out. These look pretty flimsy so I didn't want to force it. Do you bend it in the middle and pull from the middle and then squeeze the four little plastic tabs that are fitted through the mounting holes?

I am going to order one today. Definitely something to have in the toolbox

I hope it's the right way. I am reluctant to do it again. I've always been a fan of side stands as I was tired of scrubbing off the grip marks on the side of my vans where I use to lean my bike against it.

Been fitting my swing arm protectors. I had to take the side stand off to fit my swing arm protectors. I thought this would have been a ten minute job. The drive side was just two bolts but the side stand side was a nightmare. Unless I was being totally stupid it appears you have to undo the side stand pivot bolt to create space to get a socket on the two m8 bolts that hold the stand to the swingarm. I don't have a spring puller so had to refit springs first then lever side stand back into position and get pivot bolt through. I spent a whole hour trying to line up this pivot bolt as I couldn't get it to thread into the threaded section of the side stand. It went straight in without the tension of the spring but was an absolute dog of a job with spring in situ. Eventually got it in but am now worried if I've got the spring orientation correct. The springs (one fits inside the other) look very close to the tyre. Does it matter which way round they go? The thought of doing it again is painful. Why the m8 bolts aren't Allen hex heads I don't know as they would be easier to access without having to undo the pivot bolt.

Thanks for the info. I'm days away from my first outing on it. The Mitani bashplate should be here by the weekend and all the protective covers are in situ. Once it's fitted I'm good to go !! I'm almost looking forward to my first oil change .

Thanks for the info. Ive read a lot of posts about ATF in the 4rt. Why not ? My old beta rev loved it and it made the clutch so much better. Oddly in my Evo I've always ran putolene nanotech in my Evo 2t to good effect. I was asking about the oil quantities as the betas run considerably better on less oil than is manafacture recommended. I was wondering if the same applied to monts. You obviously go by the book and I'll do the same.

Do you change the gearbox oil at the same time you change the engine oil and filter. Also what quantity engine oil do you put in if you have changed the oil filter and secondly if you haven't changed the filter and just the engine oil? Thanks gaz

Thanks for the info.

I'm a nurse so syringes are never in short supply. It's the only perk !! Very useful. What oil change regimes do you use? Tell me in hours as I'm going to fit an hour meter. My bike is brand new. Never been run in even. Despite being 2020.

Ok. Sikaflex or just plain silicone?

I've just ordered a Mitani full protection with side guards from H&d racing. Was wondering what people used to attach the rubber pad to the aftermarket bash plate ?

I have done the same. Engine covers, frame covers, swingarm covers and fork slider covers. Just the sump bash plate to get now. I always cover my bike with guards. The way I ride it's essential!!

Thanks for the info. I'm tempted to go for the Mitani full protection with the side wings. I'm just going to have to get use to the oil change procedure. I'm sure the more I do it the quicker I'll get.

Many thanks for the information and the pictures. Very useful indeed. Yes it definitely protects the underside more. I honestly had no idea before I bought the bike what a faff an oil change was on the 4rt. I had a beta Rev 4 in 2008 and an oil and filter change was a simple task. I'm sure the Evo 4t is similar. What length bolts have you got on the back ? I see h&d racing do there own sump guard for £110 which looks pretty similar. I also see you have bought a case protector around the front sprocket. Is the standard montesa one no good ?

Thanks for that. Yes that would be perfect. I'll order one from trials UK.
