Thanks, feetupfun, once again!

I mounted 27x 30 mm spacers and the fork works fine. Have yet try without spacers. I'm not sure about my fork oil, I use modern Bel-Ray High Performance Fork Oil, 10W. What's your experience, opinion, advice?

Thanks once more again! Soon you have teached me to know even a little about my 348.

I was going to replace thirty years old front fork springs. The length of the new ones (which were said to be for 348!) were only 47 cm but my original are 50 cm. What's the right length? So whatever it is, I desided to lathe some nylon spacers (30-40 mm) and try with them.

Haven't yet got suitable ones! http://www.trialscentral.com/forums/index....showtopic=25084

Only the same poor zinc alloy material of both body and slide. I replaced the slide but the carb body too is a little bit worn and soon perhaps the new slide too. I want to check if this is true too for my 348, Mikuni flat slide and me: "Fitting an OKO to any Spanish bike that still has the very poor and often badly worn OE carburetion fitted, does make a tremendous difference to these machines, and results in a bike that is smoother, more powerful, and much easier to ride in serious competition." (http://www.classictrial.co.uk/okokitsspanish.html) If Montesa Cota 348 + Mikuni flat slide doesn't work, then I'll try Keihin 28 mm round slide carb.

Hi cmt320 I'm going to change from an Amal to a Mikuni 28 mm flat slide carb VM28-418 or a Keihin PE 28 mm round slide carb. Have to try which one of these two works better with Montesa Cota 348. I've bought these carbs as new on eBay with standard jetting. I'll lathe an adapter from carb to airbox. I'll start with standard jetting and then I have to try and try with different jets etc. so that at last the jetting is as good as possible. All kind of tuning info, jets and parts are available, from example: http://justkdx.dirtrider.net/printcarbtuning.html http://keihincarbs.com/home.html http://www.allensperformance.co.uk/index.html http://www.keihin-us.com/list.htm http://www.sudco.com/mikuni.html http://www.dellorto.co.uk/ http://www.showandgo.com.au/jet/jet.htm?je....html~mainFrame http://www.mikuni-topham.de/ http://www.mikuni.com/pdf/vmmanual.pdf

I just found out that BMZ however has an electornic ignition for 348. It seems to be the same as feetupfun found from France Trial Classic site, the price too is same 382 euros. http://www.bmz.fr/achat/produit_details.ph...252&id=5294 However I have so good experiences in Rex Caunt's Ignition and his helpfulness that if Rex would make ignition for 348 I absolutely preferred it!

Thank you "feetupfun"! Anyone has any experiences about this ignition? It's really pity that Rex Caunt doesn't make his ignition for Montesa Cota 348, only for Bultacos: http://www.rexcauntracing.com/pages/ig_bultaco.html I have Rex's Ignition in my Suzuki T20 classic racer and it's excellent, absolutely the best ignition you can get! Perhaps I'll wait for that Rex some day will make an ignition for my Montesa 348.

Thanks mates, I do appreciate your opinions! However I'm so poor trials rider that I don't need the best twinshock ever. Montesa Cota 348 just good for me (both she and me are heavy and our power is slow ) Perhaps I'll upgrade or improve my 348 somehow: new front fork springs, better brake pedal, Mikuni or Keihin, fat bar?

How about the younger Montesas 242 and 330?

So what's the secret of Fantic 200? I have Montesa Cota 348, could you please compare them and tell about the most important differencies?

I've read many times that Fantic 240 Pro is the best twinshock bike ever. Do you agree or...? Best features, weaknesses?

Yes, I know. Just a year ago I replaced the worn out slide, but obviously the body too is a little bit worn. The only way seems to bore out the body and insert a sleeve and sleeve the slide too. Perhaps it would be better to use some other carb, Keihin or Mikuni, even if it's not easy to mount them to 348?

Thank you very much RMM for your activity!

Tere Andre Do you know this Finnish Forum? Perhaps you could get some help from Finnish trials mates? http://www.nbuu.com/

nbrooks, are you on Facebook? There's a Montesa Cota 348 Group: http://www.facebook.com/profile.php?id=103...gid=57549537568

According to their site this fit on many Montesas but not on Cota 348. http://www.bmz.fr/achat/produit_details.ph...703&id=3924 Anyone knows if there are available elctronic igninition that will fit straight on 348?

It was both right crank seal and condenser! Two faults at the same time, that's why it was too difficult for me to sole the faults. Fortunately you mates and a really experianced Finnish trial veteran in Finland helped me. Thanks for you all!

I've mounted a new condenser last year. What kind of indications point at broken condenser?

Thanks, mates, for info!

So this alloy tank was not laminated inside the glass fiber cover? Was the alloy tank mounted to the frame or to the glass fiber cover? What kind of was the tank brackets? Montesa glass fiber tanks have often problems as all other glass fiber tanks. Would it be worth to use this kind of inner alloy tank?

Thanks mates! Axulsuv, have you any idea on the make or manufacturer? It would be much easier for me to buy them from some EU country. I haven't yet found any firm that sells those ones in Europe. I emailed BJRacing. Shipping to Finland would be $70-80, more than two levers! No deal. Have to try European dealers.

What's this? Is it homemade? Worth of getting? Is it meant to modify the standard glass fiber tank and use it only as a cover (and seat)? I see that a glass fiber fuel tank is a weak point on 348, am I right? http://cgi.ebay.es/MONTESA-COTA-348-INNER-...p3286.m63.l1177
