Mike still rides regularily and is chairman of Yeo Vale MCC....you can find his contact details on their website here Cheers Martin

Hi Tim Whats your proffessional interest........spying ? Its GCHQ, the Governments communications centre. Martin

I had this poblem at work, ............try emptying your Temporary Internet Files. Cheers Martin

In addition to whats already been suggested have a look for ATK and also Puch, both of which used the big Rotax 2 stroke Armstrong produced a "budget" Enduro/trail bike in 1985 that actually uses a Jumbo trials motor.....seem to be a few of these around in the UK. Cheers Martin

Your right, the single exit pipe was fitted to the production Jumbo's, although the works 320's also used them. Just found out that this bike was one I sold to Gary Sadler a few years ago, and it was one of the nicest bikes I have come across. Yes, the pipe does look a bit weird, but easy enough to find a replacement. Cheers Martin

Spotted this bike for sale on eBay here ..............with a very unusual front pipe set up, anyone know anything about this mod ??

Spotted for sale on an Italian website, advertised as a 240.....any ideas ??? Looks like its up for grabs on eBay, with a few more pictures. Does anyone know if there were prototype watercooled Fantics back then??? Ebay Martin

Hi Fozz I thought that Cyprus were in the E U ??....if so there should be a free trade agreement between Cyprus and the UK, so no import duty payable. Martin

Not according to the parts book Jonny. The part numbers for the friction and steel plates are the same on both the 280 and 350 motors...have just checked the book. Martin

Doesn't Legs have Vestys last Bultaco in his possession? My brain can't remember clearly as I swear I saw it and am 90% sure Legs was stood next to it. Think you'll find Legs does have one of Vestys Bultacos but then again Vesty must have had many in his time. After all the one in question is in Finland. However the advert doesnt actually say much about the history of the bike. Might have been a spare for practice or one he had for parts etc. Perhaps the person to ask is Yrjo vesterinen himself. He's only round the back of Sandifords after all Had a chat with Legs earlier today about this, and without getting into the sworded details.......I would suggest that anyone interested in paying well over the odds for this bike on the basis that it was used/owned by Vesty at some stage in the past.....should ask the seller to proove it. Martin

Right then Woody. Have a look at the attached image, and check the following 1. Have you got both the spacers (1) either side of the clutch bearing as shown 2. The washer (9) has the castleations on the inside, is it on the shaft correctly 3. Clutch nut (10) should have a recess on the inside so it will tighten down over the start of the splines on the shaft. 4. The gear (18) can be installed the wrong way round, make sure the domed centre section is pointing outwards. If all else fails I will send you up another clutch basket and primary gear to try, in case the gear drive on yours is damaged somehow. Let me know Cheers Martin

Hi Woody Have to agree with all the suggestions Malc and Stu have mentioned so far, here are 3 other things worth checking. 1. If you have the clutch apart, check the condition of the alloy part of your cluch basket. The inside of the "teeth" tend to get notched out by the plates and give a jerky feel to the clutch. File them back smooth, or if they have gone too deep a replacement basket might be on the cards. 2. The steel clutch actuating arm on the inside of the case runs on 3 ball bearings.....as described by Malc earlier. The Jumbo's had three different versions during their production, the early version was the same as the 320 with a circular actuator running on 3 small (3mm diameter) ball bearings, the later versions used a 3 pointed star affair with larger 5mm ball bearings. If you bike is running the earlier set up, check out the underside of the actuator plate, the ball bearings create ruts in the surface which interupts the clutch action. 3. Try extending the clutch actuating arm by welding a 10mm section in the middle.....was a popular mod back in the 80's on the 320's that SWM eventually marketed as a "works extra". Hope this helps Martin

Good idea Nigel.....but make sure you dont drive it into a brick wall at more than 30mph....like this example for sale in Italy.

They ran a Classic Off Road show at Stoneleigh a few years back and there was a guy selling loads of Ossa bits....could have been Peter Quinn or if not someone that had bought out his stock of Ossa spares. They had loads of new or nearly new Orange Gripper seat and tank combos....I bought one for my brothers bike for

Take a look at this Orange Ossa on ebay.....some very interesting mods, including yet another variation on the tank !! Click here Martin

Hi John Are the top yokes supposed to be painted ??? Thought they were polished alloy on the model 49......or had Spain run out of Autosol by the time they got to the handlebars Cheers Martin

Try this to set up your mixture screw on your Dellorto. 1 Start bike and speed up tickover by screwing the throttle stop in 1 turn. 2. Screw the mixture fully in and you will notice the engine revs will start to drop 3. Slowly start to wind the mixture screw out, until you notice the revs start to increase again.....at which point the pilot circuit is operating correctly. 4. Return throttle stop to prefered tickover. Hope this helps. Martin

Could well be wrong here.....but I have a feeling that Nigel Birkett was modifying TYZ's back then and may well have been responsible for that one. Martin

Pre 1979 !! Presumeably SWM's are AHRMA legal.....as they started manufacturing trials bikes in 1978 !!! Martin

Thanks for the photos Rob, a nice selection of bikes and got to admit the 84 Jumbo 320 looks mint Martin

Lets see the photo's Rob. Here's part of my Herd........might get around to getting a photo of all of them at once one day !!! Martin

The size of the seals is : 47 x 35 x 10 or 7 Rst and 47 x 35 x 10 or 7 R take a look at the following page from my site this are part for a 303 but many parts of a 300 and 303 are equal. <a href="http://home.quicknet.nl/qn/prive/sw.zeinstra/htm/fantic303/fan303_ond.htm" target="_blank"> Link to my site www.fantic.nl</a> Think those seals would fit the forks a bit better than they would the shocks

Hi Steve Are you still looking for a 330 airbox ???? I have heard that Bella Vista in Barcelona who reproduce a lot of classic Spanish bits have now made 330 airboxs....but no lids. Drop them an email via their website.. http://www.rectificados-bellavista.com/index.html Tried to pm you...but your inbox is full!! Cheers Martin

Pilot jet. HTH Martin

Hi Johnny Here are a couple of pics to get you started, unfortunately I dont have a shot of the linkage set up. However, this design was copied for Fantic and used on the 301, so maybe a linkage set up from one of these would be a good starting point. Good luck Martin
