SWM

Hi , i am halfway through re-packing the mid box and seperate silencer on my TL 320 . Have cut open the mid box and de-coked it ,re-packed it and am going to weld it up -ok. I have now cut open the back of the rear silencer (the side that usually rubs on tyre) to find that inside it only has baffle plates and no core or packing- Can anyone please tell me if this is correct and should it have cores/packing and has anyone re-packed theirs? Thanks

Would anyone be able to identify a Bombardier engine by it's serial number? I'm trying to identify a Bombardier engine that I was told came from a CanAm motorcycle. Its serial number is 75242. I've struck out in my web search. I wasn't sure where to post this query, but decided this forum might be the best because of the SWM/Bombardier connection. Thanks!

Have any of you SWM lads fitted an electronic ignition to your bikes? If so where did you get it from,was it easy to fit,what difference did it make to the bike,cost etc.Any help greatly appreciated

I ordered a new Delorto carb before i went on holiday, in an attempt to remove the lack of zip I have in first (not having reeds is also a factor), but a new Carb is only

The reed induction 350 engine fitted to the SWM Jumbo and Armstrong 350 trials bikes was also used in some trail bikes I believe and possibly some motocross bikes as well. Does anyone know which other bikes used these engines? I think they were fitted in some Armstrong/CCM trail bikes but not sure which. I'm hoping to find a spare clutch cover but it doesn't have to have come from an SWM Jumbo engine, it can come from anything as long as it fits, I don't care if it doesn't say SWM on it. If I knew what other bikes these 350 engines were fitted to I could ring around some of the bike breakers and ask, but at the moment I don't know which bikes to ask about. Anyone got an…

saw this on ebay italia.... maybe prices are on the up ? but then again they aren't ridiculous: Honda on Ebay UK And that's one of 5 :-)

after some investigation it seems that not all Jumbo's have a Reed Valve engine, rather than the 280 Disc Valve. However it seems that there is a No-Reed Valve version also. The Reed Valve Block was only fitted on bikes with engine serial number upto 178597, after that you got a blanking plate. Recent performance comparison's with my 280TL (currently in Gavin's tuning shop, ie my neighbours workshop) have got me lusting after a Reed Block, which are now not available from Rotax. It pulls well without, but is missing some of the 'rush' I'd expect and can be quite slow to get on the power (this is also probably due to the slooow action throttle). I need to do some furthe…
