If everything is right they should be very light. All of mine are lighter than the 465.Hmmmmmmmm.
MMMM all my montys have a man clutch even the 49cc cota! Its a lot lighter when the engine is running tho, if you work out how to fix it dont tell anyone but me and we'll make a squillion!So, I wait and try with the engine running?
What condition is the clutch basket in?This bike is new to me. I'm doing the initial 'investigation' to see what I have. The preliminary report is that it seems that Iver had a convention of sexy fingered amateurs working on the bike over a long period ::). My question was to see if I could find out what I'm dealing with - do I have to pull it apart? So the answer is I don't know the condition of the basket.
Sometimes the "fingers" get notched and this can prevent the plates seperating easy.
Does the clutch drag if you put it in gear while it's running.
What type of cable do you have fitted? The cable routing is critical along with the set up of the lower adjustment angle. Have you removed, cleaned / polished the clutch actuator where it passes through the clutch cover? They are not the lightest clutch but fortunately only used once per race. They never feel right if you have anything but the Amal levers assembly.Ditto the above.
I tried it with a Magura pivot and lever. The result..... :oCan't understand why something in as good a condition as that lever perch would have let go..... ::)

Graeme..I know didley squat about Montesas but know enough about bikes in general to know that something's drastically wrong to do that kind of damage to a perch. Like my learned colleague has noted, that's a pretty ordinary piece of equipment you broke, are you certain it's a genuine Magura perch? It looks like cast jobby to me, going by the appearance of the metal in the crack, and it looks like it's been on the bottom of Sydney Harbour since 1978. If the cable is in the same condition I think we've identified your problem.It's a Magura original. The crack in the metal is all new with no staining - suggest to me it snapped. The outside of the finish was weathered but I can't see why that would effect it in this application. No other obvious damage other than it was old ::).
Can't understand why something in as good a condition as that lever perch would have let go..... ::)Thanks Ross. As you see above there is a fair variation in the description of the effort required. I think the Amal has made a big difference and probably close to acceptable. But I think there can be improvements made along the lines I indicated.
If the rest of the clutch system is in as good as condition as that, well then maybe there's your problem. They're a very basic clutch. Primitive.
I doubt it's anything to do with springs. My race bike has got new heavy duty springs in it and it's still an easy pull. Try pulling the clutch actuating arm out of the clutch case and see if it's bent or something weird like that. It can only be something really obvious for it to be doing that.
All five of my bikes just have standard, run of the mill cables and Amal levers and they're an easy pull.
Pull the clutch cover off and remove the actuator shaft, check for bending/damage. Clean and polish the shaft and check the casing bore for damage, grease well and reassemble. The little lever at the bottom of the actuator also wears along with the pusher button (can not think of what else to call it).Thanks Monty, I've being working on just that 8). It all pretty good, just cleaning things and checking.
It does make the clutch pull lighter but you can't get the plates to dis-engage enough even with the lever pulled in.Thanks Ross, that's the type of compromise I'd expect - the OEM engineers generally get the mathematics right (ratios, leverage, pressures etc). Thanks again - worth the ask ;) :).
