Just had quick look and it looks as if there isn't enough room to place the cable retainer on the onside of the fork leg....odd?

Cheers

How are you relieving the clutch plate pressure? Removing a spring at a time or different springs? Cheers

hmm, rather than move my footrests and all the hassle of relocating the brake pedal, I may indulge in some higher bars...my ergo's are a very tight and I'm only 5'9" ...they do look good with a silver frame.

Ahh, good point on the decompressor, I use one on my Speedy, best thing ever fitted to a trials bike in my opinion. Kick start shaft....isn't it the later models...left hand chain run that are impossible to source or is it indeed all of them?

look more comfy than my modern flatish ones

A picture tells a thousand words....or two thousand in this case.

Hi guys, my front brake still isn't as hard as I would like. I have noticed that my brake arm is at a poor angle to the where the cable meets it. The arm pulls up and flexes sideways due to this. I also think my brake arm is delaminating and will get it to my welding friend to see if he can beef it up. Maybe bend to out to suit cable and weld plates to it? It is bad angle normal? First trial with the old bus tomorrow so more to follow.

Were there any mods for lightening the clutch pull on these bikes? It's not awful but compared to my SWM it's heavy. I have a new cable and its routed properly. I can see that a longer clutch arm will lesson the pull. I did speak to a guy at a trial with the most original Cota 348 you are likly to see and he had removed two clutch springs. He told me he had no issues with slippage in top gears? many thanks guys

Never owned anything that's needed things like cases and forks etc polishing. What's the form on getting a good finish, send them off to a pro, buy an Ebay polishing kit for my bench grinder or hours spent with Solvol Autosol? .....or easy clean ali' coloured powder coating...my local powder coaters do a very good fake ali finish.

very high bars?

that's beautiful

Damn....it will take me ages for him to forget that

nice one cheers....not too much different between mk1 and mk2 is there...I can only really see the choke being different?

The old boy I ride with tells me the idle mixture adjuster screw is an air screw on this Amal...yet I've always thought if the screw is engine side of the slide, it must be a fuel screw? So who is correct? Fuel screw...wind out for more fuel Air screw...wind out for more air Bike is a Montesa 247C 1978 but an Amal is an Amal I guess? cheers guys

that's a proper working bike, good to see

Well, to put it another way, all threads on an SWM twinshock are right hand thread. ...a few bikes have the odd left hand thread, usually found on items such as engine clutch basket nuts, primary gears, front sprockets even the flywheel....my Montesa has quite a few for example and OSSA flywheel can be on later models.

Just thought I'd drop a quick line here to thank the guys at In-Motion. Was having issues trying to source the correct cable for my Cota 247C. Was on the phone for 20 mins today whilst the poor guy at In-Motion went thru the possible cable Montesa permutations (lots!) and even went and got a bagged up cable up to measure the free cable for me, on the one we thought should fit, may not of been correct, he wasn't to know before opening it. Great service and thanks PS...now if you guys could open a well priced Trade Motor Factors near Diss with '30 minute vans' I'd be in heaven...

Well I couldn't remember when I removing the clutch basket this morning if the nut was RHT or LHT, googling didn't help and as the basket revolved clockwise I thought well it would be LHT....wouldn't it? But before I got my windy (well main'sy) on the bugger and had an exploding first motion shaft (or would that be input shaft?) I thought I'd better get on the blower to the font of everything 'Speedy Working Motor', his Holyness and the Right Reverend Mr Matthews. Martin confirmed that the thread was indeed RHT and that are no 'trick' threads on an SWM...so hopefully the next person with the same problem will hit google and find this thread and think ahh that was handy PS later day SWM's....ya on ya own.

On that approval Jon, I think I'll treat myself to a kit.

thanks

OK, I think I understand this tortured way of screwing an engine together. It appears that the head is secured to the barrel by studs coming off the barrel, barrel is then secured to the crankcase via studs coming off the crankcase to tubular nuts with allen fittings..correct? ...and these barrel 'nuts' frequently sieze? ...is there anyway to apply say Plus Gas or WD-40 to these problematic nuts on a regular basis to avoid any future issues or are the nuts blind being covered by the head? ....hope that all makes sense ....for the love of Mary, just what have I impluse bought?....metal on metal clutch plates, clutch springs held on with pins, brass clutch thrust bearings, odd sized pistons made from Unobtainium, tapered front sprockets, flywheels needing Cornish Beam engined sized pullers...anything else to add to the party? But the old girl really is growing me, we seem to be a having a love/hate relationship, sort of takes me back to the 80's when I had a Spanish girlfriend. Lovely to look at, body to die for. But somewhat strangely wired with a few handling quirks, excentricities and surprises. So today I'm in love, te quero mi moto mas bonita...yesterday we were talking who had the house... cheers guys

Did a search but came up with now't. What's the situation with the fuel tank/seat unit interchangablity between the older Cota's of all flavors, say 1974 onwards? I notice that 247 have single downtube frame whilst the 348 have a twin downtube so the frames can't be the same, so my thinking is that 247's don't cross over to 348? Also, did all UK spec' Cota's have false 'tank tops' with a metal tank under the cover, was there a cut off year? My own 247C is 1978 yet has a glassfibre tank. I know a metal fuel tank was mandatory for road use until the late 80's (a SSDT question there) I believe but then again, not all UK spec' trials bikes had metal tanks, Fantic for example were all plastic when SWM's ran a metal tank if UK spec' unless I'm mistaken which I often am. cheers as always guys
