I'm just about to order some new fork seals and was wondering why there are 2 in each leg? Is it because 80s seals werent up to it? If so I would fit only 1 to reduce friction???? (with suitable spacer). Ian

Finally think Ive found all the parts required for the little 200 but what oil and how much in the gearbox/clutch? The oil in there is green and just looks like Duckhams multigtade engine oil. Many thanks

Hi, I am puting my Cota 200 back together and I need to know how much end float the gear shafts should have? And which end the shims should go? I am disregarding any shims I took out as it had been rebuilt by Neanderthal Man!! If anyone has an exploded diagram of the gearbox that would be good as I have made some educated guesses on how it goes!!!! Thanks Ian

Now the Cota from hell has a shiney new piston and barrell bored to suit, I need to spend even more money on brake shoes! Which are best and are there any brands I should avoid? As for gearing standard according to the manual is 11 - 54 or 10 - 49, is this OK? Anyway here are some pics

Can anyone point me to where i can buy a replacement kickstart lever for my 1980 Mont cota 200, also needed a Petrol cap 'bung' type, Cheers, Vaughan.

Just bought two 1981 cota 200's which have been sitting idle in a barn for a couple years and I was wondering if anyone can tell me the volume and correct type of engine oil to use? Any help will be much appreciated.

Hi, could somebody help me out with a few quick q's? I need info on a 1975 Montesa cota 200, Fork oil quantity and grade, Correct fuel mixture, Crankcase quantity and grade?, Thankyou.

Hello, I was hoping to fit lights to my cota 200 so I bought some genuine mont ones second hand, I started to investigate how to wire them up so looked at the generator side but I could only see through the slots in the rotor one coil so I am assuming that this is for the ignition and that the coils for the lighting have been removed. Could someone confirm that there should be more than one coil and if I need to replace the stator would one from another model fit . this would widen the search for available parts. I'm also looking for a workshop manual but there does'nt seem to be anything specific to the 200 would the Clymer manuals that pop up now and again for the 123…

Hello all. I'm rebuiding a Mont 200 the one with the alloy tank under the F/glass tank and seat unit. I understand that there are two sorts of rear guard, LONG and SHORT, There seems to be a black plastic shield behind the air box does this mean I need a short guard? any help would be great as I've nothing to go by. Also would this model have the chain tubes as standard? Thanks in advance.

I have a 1983 Montesa Cota that I have gone through pretty well and a friend of mine has a 1976 Montesa Cota 348 MRR that is basically stock. After riding mine for a few months, I rode his and noticed his seems to turn and steer much more easily and smoother than mine. I have modern pegs on mine that slightly lower and push back the foot position. I have also installed stiffer fork springs and after market Works Performance shocks. Anyway, does anyone know why the older bike seems to steer better than the newer bike? Is this an inherent trait of the 1983 242 or is is just a personal things as to what each rider might prefer? Any ideas?

Hi Got an old 247 for a song the other day ($20 Australian) except the motor had seized. Started pulling things down to get to the problem and found that the twit I bought it from must have gone into deep water, filled the crankcase with the stuff and just left it after it would not start. There is rust in the crankcase chamber and have managed to get the motor turning albeit tightly. I know the proper thing to do is to split the cases, replace bearings etc etc. but before I do that can anyone suggest how I might be able to flush all the rubbish out and getting it turning a bit lighter? If I can do this I will try to start it and see what happens. Any help much appre…

Hi there, Does anyone know if anybody makes a sump guard (bash plate) that fits the Cota 247. I know they didn't have them fitted in the factory but the bottom frame tubes of my Cota are getting quite chewed up and could do with a bit of protection. Thanks Simon

Hi, Just bought a '75 Cota 247 - nice bike and looks to be the same as any other Cota BUT it has what was described as a 'one and a half seat'. The seat is deep and padded, not ideal for trials but it'd be nice and comfy on the road. Its obvious that its genuine Montesa and not just an aftermarlet seat but I can't find any pics or details of it anywhere else.... Anybody know what it is ???

The Amal on my 1972 Cota 247 is just about worn out and I am thinking of changing it for a Mikuni. Has anyone done this mod and can give a walk through of what is required, jet sizes etc etc? Thanks!

Hi, my latest project is getting costly as i have just pressed apart the big end to find the rod is ovaled and knackered. Anyone know where i can get a kit from or at the least a serviceable rod? cheers Dave

I'm helping a friend redecorate his Cota 247 tank and want to know where the "MADE IN SPAIN" decal was originally located. I have looked at every photo I can find in books and on the interweb and cannot find a photo showing the location of this particular decal. The owner thinks it should be about 50mm to the rear of the fuel cap hole but I want to make sure. Can anyone help please?

I now have a cota 247 Frame no 21M253** circa 1979/1980 I have seen a couple with mods done to the Rear Shocker angle and also the bottom tubes being replaced with a full (more modern style) one peice sump guard and obviously replacing the standard footpegs with some more modern ones. Does any one have a handbook/maual available with all of the fork/gearbox/clutch oil amounts etc Any advice would be a great help. Thanks & a happy New Year Wobbler

Hi, do 247,s have a copper ring head gasket or just gasket cement as my one didn't have a head gasket but had two base gaskets Dave

Hi All, I'm getting my 1971 Cota 247 ready for the upcoming vintage season, and I've got an oil leak that is driving me crazy. Both the gearbox and clutch drain plugs just refuse to seal (the 2 large flat head screws on the very bottom of the engine). I've tried fiber washers, aluminum washers, and rubber o-rings, with no joy. The fiber and aluminum washers continued to leak, and the o-ring just pushed out from under the head of the screw. The leaks are slow, just a small puddle after a day or two, but with no way to check the level, I have to change the oil before each ride. Any suggestions?

Hi - I have the Amal blues, just can't get good all round performance after spending dough on new jets, needles etc - I have been fooling around with a 2nd hand Mikuni VM26 from a DT175. It is in good clean condition and I have made sure all the jets are clean and operating. I have rigged up a suitable adapter to connect to the original air box. When I kick her over it fires then dies - after a few kicks I remove the plug and it's always wet. I did get her running roughly only at high revs and loads of smoke ( engine must have been loaded up) so I removed plug and left it overnight to dry out ( fuel off). Next day I removed the air filter - double checked seat need…
