I use a luggage strap with the ratchet tightening mechanism. Strap is about 1" wide and I wrap it twice around the magneto then tie it off to the frame.
Like the idea of this! I've got one of these ratchet straps, I'll give it a try tomorrow and report back.
I need to change the points and condensor on my MH200. Any tips/tricks on how to lock the crankshaft to stop the engine turning when removing the flywheel nut?
Also can someone confirm that the nut is reverse threaded? I've heard this but I'm not 100% sure.
The tank has already been painted at some point, and they made a pretty good job of it. The paint's not bubbling or lifting, it's just looking a bit tired, with scratches, staining, chips etc.
Any reason why I can't just give the paint a light sanding and blow it over with a new top coat?. That way I wouldn't be stripping the tank back to the original plastic Would I need to prime it first?
Zerorev3rev4 - When you say there is an idle adjuster, do you mean the pilot screw? And where is the mixture screw? Sorry my carb knowledge is pretty basic!
Newly restored MH200. Still to do the decals which are on the order. Been in storage for the last nine years, but started pretty easily after a top end rebuild with new rebore/pison, small end, kickstart spring,cables, plug, oil etc.
Still a bit of tweaking to do, number one being it refuses to idle (see my thread!)
Just finished restoring my Montesa MH200 (new 2nd oversize piston, rebore, plug, oil, cables, kick start spring etc)
Bike will start fairly easy on the choke, but doesn't want to idle. It has the MK2 Amal concentric carb.
Does anyone know how to set up idle adjustment on this carb, as it doesn't appear to have an adjusting screw. Also, the revs don't drop off as quickly as they should when throttle is closed. Could this be connected?
Hi all, I'm in the process of restoring a Cota 200, starting first with splitting the crankcase to replace main bearings. After removal of cylinder head & barrel, I've noticed there's some light scoring on the bore and piston skirts.
Anyone know the best place to get a rebore/piston kit done in the UK?
that assembly looks incorrect it should be starting from inside working out ,, 1 inner small bush 2 1x washer (poss shim) 3 cog 4 ratchet mechanism 5 light spring 6 large washer 7 shaft 8 heavy return spring 9 large washer 10 outer large bush in outer case 11 seal 12 kick start ,,,, the assembly can be kept in the engine when removing cover just by keeping it pushed in when lifting the cover ,,,, if the clip is popping off the idler gear check the groove in the shaft for wear and also remember circlips have a incorrect and correct way round and best to use a new one if its popped off
You might be right, I've just had a look at the parts diagram, and think I may be missing one of the large washers. I'll need to check next time I'm at the bike. Are the washers available - (part no is 0265.118). or any one know what size they are so i can replace?
RE. DESIGN FAULT . - THE PROBLEM WITH THE GEARS IS THAT WHEN THE CLUTCH CASE IS REMOVED THE SHAFT PULLS OUT WITH IT ALONG WITH THE TWO RATCHET GEARS + 2 WASHER /SHIMS .THESE ARE THEN OFTEN ASSEMBLED
INCORRECTLEY LEADING TO THE KICKSTART GEARS BEING MISSALIGNED AND NOT MAKING FULL CONTACT WITH EACHOTHER , LEADING TO GEAR TEETH BENDING + EVENTUALLY SNAPPING BITS OFF . EVERY BIKE I HAVE WORKED ON
WITH CORRECTLY SPACED GEARS HAVE HAD NO PROBS . AND ALL DAMAGED GEARS WERE BECAUSE OF INCORRECT SPACING
ON REASSEMBLY .
Thank you, one of the most useful bits of advice about the Cota 200 kickstart issues.
Thanks, do you have a diagram or know the order of how the washers and spacers go, as im thinking about buying one which has the problem of the circlip on the shaft falling off aparently due to a wrong sized washer some were on the shaft, when the circlip falls off the primary gear disengadges stoping the kick start to work.
I know it's an old post, but just thought I'd add this photo of the assembly after removal (ignore the broken kickstart spring) Woodbutcher is right, the whole assembly pulls out with the case cover.
Just bought a 1981 (I think) Cota 200 as a project bike.
Needs a few things done - Main bearings, kick start spring, service items, I'll probably go over the engine while the crankcase is split. PO has supplied lots of new parts with the sale.
Couple of questions, I don't seem to have a chain tensioner, and I suspect the fuel tank might be leaking slightly?
Any advice/links to manuals, workshop or owners, parts suppliers, tips, info and just general experience with this little Montesa very very much appreciated!
