I remember someone posting that a good set up on my 1980 SWM 320 with Marzocchi forks is to keep the Marzocchi triple clamps and use the Betor forks? I realized that my spare/project 1980 SWM 320 has the Betor forks and triple clamps. Would it be worth it for me to put the Betor forks (after I go through them) on my competition bike with the Marzocchi triple clamps?
I was told the double ring piston last longer. Performance wise I would think you would get quicker revs from a single ring piston. From what I’ve seen trials and enduro engines Usually have double ring pistons, motocross bikes have the single ring.
Anyone have a good source for the 280 pistons? I’m going to rebuild my 1982 TL320 and will probably need a oversized piston. Heard you can use 583 Ski Doo or Sea Doo pistons. I definitely want a two ring piston.
I’m just building my stand from what I have laying around the shop. It’s all cut out and drilled, I’m just waiting for a little warmer weather to weld it up in my unheated shop (my welding is done in the unheated part, my small but warm workshop is where I work on my bikes).
Yeah I got into vintage trials and have a few bikes to rebuild. Plus I bought a new Mig welder over the summer and wanted a good project to do with it. I started cutting the pieces for the stand.
Anyone build there own engine stand? I’ve used the wooden box stand for years. Decided to look into building a metal stand that rotates. Here are a few ideas I’ve found.
I wish my SWM was set up as nice as yours! I’ve had no luck finding the Aprilia clutch cover. I will have to look at the cost of the smart carb, would be nice not to worry about jetting.
I have been reading them. A lot of info! Thanks! I have a newer style clutch cover from a Can Am that has the bigger actuator balls. I’m going to try it this winter. I noticed the other day my bike is leaking oil from the Kickstarter/shifter area. It leaked a couple of years ago and I replaced the seal and o ring. I will replace them again when I install new cover.
When I bought the bike it had a couple of clutch springs removed. It slipped way too much for my weight. I reinstalled all the springs. It’s not super hard to pull in just not a one finger pull. Thought a hydraulic setup would make it one finger.
I know ATK modified the Magura hydraulic kit to fit the ATK 406 Rotax (similar engine as the 350 SWM Jumbo). Not sure if there set up would work on the 240/280 rotary valve engine.
Anyone try one of these for hydraulic clutch?

I have a good stick welder I haven’t used in a few years, I should use it again. I mostly use my Mig. I have a torch set just need tanks. Thought about getting a tig but too expensive.
Looks great! Are you guys using a Tig welder? I only have a Mig welder and was told the chrome moly frames needed to be tig or bronze welded. Mig welding transfers too much heat.
I’m planning on going through my 1982 TL320 this winter. I’m thinking of making it my semi modern bike. I seen someplace where someone installed a front disk brake. I’ve also seen some hydraulic clutch mods on the SWMs. Electronic ignition and new carburetor. Any other ideas? I have a 1980 TL320 that’s mostly stock (except electronic ignition) that I can use for vintage legal events. The 1982 I would use in modern events.
