SWM

hi guys, My understanding is that a swm 125 bottom end is identical to a 240/280. have i got that right? We have come across a 125 engine that would be a cheaper option than repairing the gear shaft on our 280 in the short term and eligible for my daughter to ride junior. A couple of questions. does the 280 exhaust fit the 125? Does the 280 top end fit straight on the 125 or do we need to machine the cases? What gearing is used on the 125? Any help appreciated. Cheers Mark

Restoring a 240 Swm and the rear silencer box was full of the usual crud and also the the two baffles had come loose virtually blocking the way out for the exhaust gases. Is it best to reweld the baffles back in to their original positions or can you leave them out to let the engine breathe easier? Thanks.

Hi all, I have got a 1982 / TL320 in the workshop to get the rear end sorted with a new tyre, brake shoes chain and sprockets etc.. I was was quite surprised to see that where it has been standing a small amount of oil has been dripping from one fork leg. The seals are almost new (fitted in Okt. 2016) and the bike was used once for about 1/2 h before weather stopped me. The chrom and the seals seem fine. Can it be that air pressure is building up in the fork leg ? Does the fork cap have a bleeding valve and when it does should it work in both directions ? The forks are the last 35 mm Betors and silver coloured that just have one 35 mm x 47 mm x 10 mm seal (not like i…

Hi does anyone know if you can get an alloy gear changer for an SWM , or if one from a modern bike will fit, many thanks.

can anyone tell me if a swm kickstart is the same as a aprilia tx311m

Just found this film of the SWM factory from about 1978.........how I would have liked to take a trip around there. https://www.facebook...&type=2

Hi all, new on here but have been looking at the thorny subject of SWM clutch upgrades on the TL models. after pulling the clutch to bits several times and not being able to improve the standard set up i by chance got talking to Gary at Sportax Racing, he was able to supply the Aprilia type kit with 12mm ball bearings and also some standards generic to all motors, standards clutch springs. The springs are lighter than the 37mm ones fitted and also shorter at 33mm. The difference is massively noticeable ( just about one very strong finger😁). Apparently the 37mm springs are classed as heavy duty and due to their bulk when compressed, they can foul on the basket and pos…

I thought you SWM enthusiasts might enjoy a picture of my SWM project .The bike is a 1980 Tl 320 that was originally sold in England, imported to Califoria in the late 80's and found last year in a salvage yard in Montana. I have tried to replicate Bernie Schriebers last Factory TL320 before he started riding the Jumbo. My project incorporates all of the mods from the french Burgat article on this forum and everything I could see from the photos in Bernies' book "Observed trials". My only real change from the original factory bikes is a modified Pro Circuit Racing silencer that weighs about a fourth of what the original did. That and other weight reduction mods bring the …

I have dragged my bog standard Jumbo from the depths and have a clean slate to play with. It is totally stock and runs the case reeds. The footrests do not have a return spring and I cannot see how one is fitted. It is also fitted with SWM (Betor) 35mm forks, it is my understanding that the first bikes had 38mm. Were they changed at the factory during the last days? Overall the bike is in excellent condition so I assume they are standard factory fitment. What other modifications would you recommend? gearing, carb (26mm perhaps), exhaust system, ignition timing. Thanks for your help

Hi, afer I rebuilt my TL320s motor, gearchanging was a dream. It stated getting problematic going down the box especially from 2nd to 1st. Now it is also a pain going up the box from 1st to 2nd. The clutch isn't dragging so something with the pawl setup seems to have changed. Any ideas ? Phil

been thinking about it for a while, but with three SWMs in this weeks Sammy Miller round maybe its time for some SWM riding shirts ? Had a look on the Destroy Clothing website and they do a vintage style shirt (for Honda's and Bultacos for example) but they will make up an SWM logo'd shirt (the Racer style at bottom of the page) What ideally I need is; a good picture of one we can copy the style of (sure there is a picture of Danilo Galeazzi wearing a shirt with an SWM logo around the neck at the SSDT, but cannot now find it, Motosinge?). Making up 15-20 shirts will take a few quid off the price, as potentially would putting on a suppliers logo and URL (?) Anyone inter…

hello someone has used climber engine parts for motor SWM?

Could somebody help me with the thread direction for the clutch side crank nut [more like a cylinder with a 1/2 inch square female]? Any tips on replacing the crankshaft seal would be also be most welcome?

need to give my rotax crankcases a tidy up , whats the best option on primers ,paints etc

Here is a video of my 1978 SWM TL320 Engine Rattle. Is it a problem as I have heard several at Trials that sounds the same or louder?

[/img] Nice bike too good to ride, must be one of the last ones, looks like new

Just finished the istall on third SWM of OKO carb.The bikes were 2 1982 280s and a 1983 240. the 240 had a stock airbox and pipe and the inprovement was huge.bike pulls from idle to full revs with no flat spots.The 280s run tons better with no problems, one stock the other has a modified rear box.Also noticed after first trial the bike used less gas than before.I also am using 2 different size OKOs on one of my xc bikes.It has a 280 rotax motor and for the tight tracks i run a 30 mm carb and its a tractor .On more open tracks I install a 32 mm and it runs down 450 4 strokes.Have to thank Roger at MAVT.org for the carbs and tuning help.

I did find this Tl 320 and have to get it tough I haven't finish my TL 125 yet. Look the frame number!! It is also in registration papers 0001. Is this the first one?

Anyone know if there are any difference to the steering angles between a Black 1981 SWM frame, (with full mudguard loop) and a 1983 Blue frame without rear frame loop ?

Hi does anyone know where i can get a dating certificate for a 1980 SWM so i can register it for the road. Thanks
