jon v8 Posted October 15, 2011 Report Share Posted October 15, 2011 H - Heavy O - Old N - Nails D - Dreadfully A - Asthmatic Only joking, they're not that bad but not the best by a long way without mods. Although I said every bit of Lejeune's bike before, it wasn't a production bike so I'd have to go with a Fantic 240 or a Majesty 320 as best twinshock available to Joe Public. Can't think that you could mix and match parts from other bikes to get a combination significantly better. Being an Ossa fan I would nominate a MAR but as the post was to suggest the combination of parts to achieve the perfect twinshock I have to keep it realistic. The MAR was way beyond perfection Having recently ridden Mick Andrews 310 Ossa, I have say you could do alot worse,first Ossa I've ever ridden - I've started sniffing round E-Bay again...

woody Posted October 15, 2011 Report Share Posted October 15, 2011 That is a 'Spanish' Ossa though with just a few mods. A little different from standard... Quote Link to comment Share on other sites More sharing options...
andy m Posted October 15, 2011 Report Share Posted October 15, 2011 (edited) Are there any links to the Spanish bikes, I found some recently but can't seem to find them now. Majesty is still here, winning bidder didn't contact me. Edited October 15, 2011 by bo drinker Quote Link to comment Share on other sites More sharing options...

woody Posted October 16, 2011 Report Share Posted October 16, 2011 Do you mean it was modernised in Spain ? What has been done to it ? Yes, not sure which specialist did Mick's but it is modified. I've not ridden his but I've ridden another one which has similar mods and it was very goodThey only use parts from the correct period. Mick's is a 310 (or at least it was originally, I think it still is rather than a 250) Head angle is steepened but I think it is just so they can use leading axle forks. Ossa steering is pretty good as standard but if you fit leading axle forks it spoils it. Hence I guess the angle change. Marzocchi forks and Grimeca front wheel. Rear swingarm from an MH349 Montesa which is longer and I guess to get back the wheelbase from steepening the head angle. Frame looks standard with even the older shock positioning rather han the later angled position. Different rear silencer which is probably straight through packed type rather than the original baffled type. Not sure if anything is done to the middle silencer but there isn't much room on an Ossa to alter it much. Longer front pipe like the later MK3 onwards bikes but a different shape. Rear wheel is Grimeca allowing for a rod operated back brake. The original MAR set up is a tortuous cross over spindle and cable affair. Probably, the engine is ported to make it smoother and rev more freely. I don't think it has a reed valve. I remember Mick saying when he first got it that it may have a bit too much go and he thought they had removed weight from the flywheel but when he looked they hadn't. It's probably got a modern electronic ignition on it. Suspension is Magical shocks and front spring set up which work really well. I'd love to have a try on it as I bet it is very nice to ride. The modified 250 I tried when I was in Spain was very good and would be very similar to Mick's other than it retained Ossa forks and used a Montesa 242 swingarm. It is owned by the man who makes the Magical suspension kits and shocks. That's about all I can remember Quote Link to comment Share on other sites More sharing options...

That's about all I can remember I had a go on the bike last year and it had far more go in it than my 250 engine (which Mick rebuilt)so id say it was a 310 then< the rest of the bike rode alot like a fantic 240 , but i suppose that was the idea. It really is that good. Quote Link to comment Share on other sites More sharing options...
jon v8 Posted October 17, 2011 Report Share Posted October 17, 2011 (edited) It is a 310 motor,which sounds really fluffy and woolly at low revs like its come off choke too quickly and needs a warm up and clear out.But when you ride it you realise how smooth it is,then when you open it up it revs very willingly with plenty of power.I dont thnk it has a reed valve.I didnt look too closely at it - I was more interested in how it rode,and keeping up with Mick who was on my TY250. The forks are Fantic and as said the rear shocks are Magicals. Other than the lack of tickover which caught me out, the only thing I would change on it would be to raise the gear lever slightly.Apart from that I thought it was one of the nicest bikes I've ever ridden,esp steering and suspension wise.

andy m Posted October 17, 2011 Report Share Posted October 17, 2011 Stafford auction this weekend. http://www.bonhams.com/eur/auction/19290/lot/271/ http://www.bonhams.com/eur/auction/19290/lot/272/ Quote Link to comment Share on other sites More sharing options...
woody Posted October 17, 2011 Report Share Posted October 17, 2011 Other than the lack of tickover which caught me out, Ah - a real trials bike... It may have a bit of porting done which is why it feels like that at the bottom end. As a rule, the Ossa is probably the smoothest bike you can get off the pilot jet - especially when Mick's jetted them. Can't believe how much that 250 Bulto went for. There was a very nice blue 198a on ebay a couple of weeks ago with a polished engine, really nice rebuild and it only made Quote Link to comment Share on other sites More sharing options...

andy m Posted October 18, 2011 Report Share Posted October 18, 2011 Stafford prices for many bikes were low, Japanese bikes especially. Some Brits did well. Can't comment on the Bultaco and Ossa, not my field. Majestys on ebay recently failed to sell, some high start priced Tlr stuff on there with no hope of a bid, maybe things have levelled out (for the wannabe investors/polishers) Quote Link to comment Share on other sites More sharing options...

jon v8 Posted October 19, 2011 Report Share Posted October 19, 2011 You seem to have missed the real ingredient! The 'Perfect twinshock' is achieved by popping somebody onto it that can ride the bladdy thing! This is very true,a few people who in the past have suggested I trick up my bikes.... I can only say that getting them into a tidy,well maintained state so they do the same thing all the time is all you need to do.Its the rider who needs to trick up,my ploy to lose weight and get fitter is working well.Also spending a day with Mick Andrews has made me realise how much more I need to plan and consider each section.Thinking about where BOTH wheels are going to end up on a chosen line etc. Quote Link to comment Share on other sites More sharing options...
