Was your bike always like this? Or is this something that has just come up. This bike is absolutely new, I don

Here is the situation. I tried a 2006 GG TXT250 yesterday which is almost brand new. The engine sounded excellent but when I tried the bike, the shifter mechanism didn

Hi, I hope your project is going well. The Montesa Cota is a pretty basic engine, but like all they have their special points. If you need to know anything, let me know and I will try to help. I have rebuilt a number of Montesa engines without any problems. I have never seen a REAL shop manual from Montesa. I have what looks to be a typewrtitten document (incomplete) in Spanish which goes a little deeper into the engine repair than the user manual, but no great help. If you have a doubt, let me know perferably by email. Let me know what the specific problem or question is.

I added a 30mm spacer below the bars and let me tell you what a difference 300 mm can make! I had to make this out of an aluminum block as the Cota 350 has this U-bolt type setup instead or regular bar clamps. This lets me be in a very good position, still tiring but a least my torso is at a 50

Hi, I was wondering if you guys could give me an idea of the correct posture on a trials bike. Obviously, your going to be more bent over and cramped on the bike if your 6 feet tall than if your 5 feet 6. But yet I never see any raised bars on trials bike. I have a Cota and am 6 feet tall. I recently finished a long trial with an rally between zones which was about 36 kms between the sections. I was dead from being bent over so long. Any Hints, tips on the desired posture?

Your lucky it is a 250, pistons for the 350 are hard to come by.

Thanks, my gripper took a while to get together. The bike was in really bad shape and was rebuilt completely, engine and all. I really don

I am trying to get my Montesa Cota 350 clutch to work perfectly...ha ha. The clutch drags when it is cold so the cable has to be tightened too much. When the bike is hot, the clutch works good and the cable can be loosened a little.
Sadly, I have a bit of experience with the Montesa clutches but I

Drain the oil and clean the threads on both the oil plug and the crankcase. Once they are nice and clean with no oil residue on either (drain well and clean with a little gas or alcohol) put some loctite silicone gasket maker on both threads. Put some on the fiber washer as well. Tighten and it should be ok.

Just a hello from the land of Montesa, Ossa, Bultaco and a lot of other brands that never made it out of the country. My name is Robert, I

Remeber not to overtighten the clutch nut. Use the special lock washer that is made for bending over the nut to hold it in place. 14.5 to 18 ft.lbsl is more than enough torque, if not you can actually break the aluminium cover.

everything in Spain is very expensive, especially for the gripper. You might want to see about buying a wreck somewhere for parts. I just finished a Cota 350 as you may have seen some other posts. Good luck and keep in touch if you have any doubts.

Hi and good luck with the restore. Classic fasteners in Australia has all kinds of nuts, bolts etc. I

It is going to be hard to find the front section only, how about a complete pipe?? maybe the front section can be repaired?? Let me know what other stuff you need maybe I ca source for you here in Spain (hard). I recently restored two grippers. See attached foto.

Thank David, I have mine shimmed to be a lot tighter than that, I am talking about 0.10mm. I don
