  1. ATF as B40, worked fine on mine. Any clutch drag, whip out the metal plates, rough up with 80 grit and enjoy.
  2. Much of the issues with these SWM clutches is simply down to incorrect clutch lever and perch, decent cable correctly routed, proper set up, roughed up steel plates once they get old and polished and draggy. Need to be OE Domino, but they get broken and owners go cheap, then the bikes change hands and, well you know. My mate had a brand new Tl320 back in the day and the clutch action was a revelation after Spainish ones. Out of all the twinshocks I've owned my TL320 had the lightest pull and smoothest consistent operation of all of them, Sherpas, Cotas, Honda TL, Ossa, even my Beta Rev I kid you not.

    OKO Carburetors

    Why not go OE Dellorto? Last time I bought a properly jetted, as in original spec' Dellorto is was £120 with delivery.....bolt on, no faff, good to go, enjoy for decades. Those OKOs are probably ok but some do have I issues with them, I know my Honda Camino runs a Wabron, a good copy of a butterfly Keihin, but, again some have no end of issues. Just a heads up. 😎
  4. Thanks for the reply. From memory the 349 is actually a 349cc, a first for Montesa, a model nomenclature that makes sense😀
  5. Snap, sort of. I once trialed a borrowed Beamish, a lovely looker, a right pain to ride😀
  6. No idea, quite a few in the Eastern Centre. I've done a few minor jobs and lookysees on my 247C and, it appears a well nailed together bike, nicer than my Bully was. Some excentric bits like tapers but, bar that nice to wrench on.
  7. Hi guys, this old girl has popped up for sale up the road and, looks like I'll be the new owner. All there, up on it's toes, bit of cosmetics hopefully...ohh, those mudguards😀 It'll join my 1978 247C which is my first ever 'keeper' twin shock having owned an SWM320, TL125, and Bultaco 198B twice. The old 247C is light, nimble, small with a smoooooth and easy engine, we just get on if you get my drift. Always had a soft spot for Montys. I know the 348 was really a 305cc but compared to the 247C, a bigger bike, heavier and, I'm wondering a bike more suited for an expert rider... I'm more a, well let's be honest, certainly, more novice/intermediate but, hey I'm expert at observing. So, 348, hero or villain in my hands? ... I'll bring it home anyway as I'm very shallow and, like pretty things in bright colours😀 Thanks guys
  8. Maybe useful, there's a few VM carb threads here. Mikuni Tuning and Jetting Guide - THE VINTAGE BIKE BUILDER http://www.vintagebikebuilder.com/mikuni-tuning-and-jetting-guide.html The OKO is a VM copy from what little I know so may help on these too. 😎
  9. Hi there, maybe worth checking if you have the 'correct' jet needle and body. ......from your symptoms, I wonder if your throttle slide has too small a cutaway, again various sizes available. Good luck.
  10. Many thanks for your help guys, very interesting 😎
  11. Title says it all really.....or more a case of what was lying around in the p*** and panic before they closed up shop? Many thanks guys, stay safe
  12. Dave there is a Facebook site dedicated to the 247, lots of 247C owners on there😎 Great bikes, I love mine, super smoooooth engine and physically a small chassis, all really helps on the modern day sections. The 'C' is for competition, they were designed to be lighter than other '247' class bikes. The odd cubic capacity was something to do with French tax breaks as France was a large market for Montesa back then. You'll probably know by now that most simply put a '250' jug 'n slug on it as the 237cc pistons/rings are made of unobtanium.
  13. looking for a website for trials events, enduro and road/circuit racing would be a bonus too ...off to tour France late August by 1992 Honda Revere again (remember them?) or new fangled high tech Wee Strom not sure which yet, so would be great to take in a trial etc Then off to Northern Spain. cheers guys
  14. I know the current wisdom is 250 jug n slug but is anyone doing the original 237cc piston kits yet? Cheers guys

    Steering

    PS I should add original as left factory, some bikes head angles 'fatten out' with use so I'm told?

    Steering

    I've never ridden a cut 'n shut that rode any good....they tuck under or fall into corners in my experience. Good friend of mine has a very modified TY175 on mark 5 frame, nothing on that bike is std bar steering geometry. He has tried various head angles but feels Yamaha got it right back in the day.
  17. I gota say, my SWM 320 1980 std bar 10mm on the arm was THE best clutch of any trials bike I've owned, modern or old. I rode a new 1982 back in the day and that was fine too. Just had new proper cable, proper Domino leavers and perches, steels roughed up with 80 grit, running ATF, set up correctly.....and greased balls oooer.
  18. PS I do wonder why trials shocks have gas over oil...it's not what I would call a heavy duty cycle?
  19. Wow, I've never seen a C clip to retain a rear shock. Cool idea. I took the shocks off to grease up the mounts & fter looking at my shocks closely they are actually quite new, they have 504B on the bottom of them? Compared to the gas Betors on my SWM, they are a little oversprung for my weight. These shocks are all black and oil only, no gas, possibly NJB Clubmans? I'll give the boys a call tomorrow. Thanks for your help guys
  20. Hi Andy, a bit late to the party but hey, so what. I've the same bike, a 247C (Competition) and they are lovely bikes, light, small with a very friendly and smooth engine. The early ones from June 1978 had front fork spring air assist whereby you could pump a little air into the front end to firm them up. This feature was soon deleted though, as they couldn't get the air to remain in the forks.....sounds familiar to modern MX boys Mine is heading for a rebuild in week or so, only for a frame repaint as the tank paintwork is still original and they are only original once. PS Your air filter is correct.
