How about this one? Not strictly twinshock though. http://cgi.ebay.co.uk/OSSA-Cantilever-clas...4QQcmdZViewItem

The video is definately not from this year,I just got back home last night from there. How do I know? No Montesa this year and the lovely Victoria was riding a blue Bantam this year.

I had a go on a mate of mine's 250 Beamish a few years ago.I like it,nice power,good suspension and well finished.The only negative I thought was the rake is very shallow,bit of a barge to get it to turn tight.Great over rocks in a straight line though.I don't know what the spares situation is like?

I don't think you can tell just by looking at it.Only way is to try a new one,I think.There is some resistance tests you can do,look on Bradford Ignition services website for details here http://www.uk-motoplat.com/home.html I'm not sure how reliable the tests are.My friend has a Bultaco Pursang classic scrambler which had no spark,I done the tests with my basic multimeter and it tested ok but a replacement stator fixed the bike.

Go for the 250.If it is as good as you say,price is about right. There is no restriction as to what size bike you use,you could ride a 125 if you wanted. It is only if you are under 16 then you are restricted to a 125 for national level trials.

Try taking the nut off the flywheel and tap it a few times on the outside,it may not be too tight on the taper and will come off.Mine came off easily. I would also advise anyone to always have a kill switch wired up to their bikes.I have seen people fall off in mud or on a hill and the throttle jams wide open.With no kill switch how do you stop it? By the time you turn the petrol off and the carb emptys it will have done some major damage.Just my opinion mind.I race twinshock scrambles and am not allowed to ride without a kill switch.

I've never owned or ridden a Cota 315 so cannot really comment,I have heard they are a bit fiery top end.Others will know better.The Honda engine is bulletproof I think. The only thing about the one on the bay is the 'never used in competition' line,I have experience of buying field/play bikes and they are usually abused.Tyres,chains and sprockets are usually shagged,oils are rarely changed,any old cheap lawnmower 2-stroke is used etc. You get the idea.My advice,leave alone and buy a bike that has been trialled and looked after properly by a rider who knows what he is doing.They are competition bikes after all they are made to compete. On the bike to buy in your price range? Find the best Beta Rev 3 200 you can find.Dont think a 200 will be underpowered,they have plenty of go,lovely and soft at the bottom as well.You will find grip where other more powerful bikes will spin up.

My Techno did exactly the same thing,went to start it to check all was ok for a trial,wouldn't start.New stator from Lampkins fixed it.

M10 Sherpa. 1965. The reason why pre-65 is pre-65.To keep the Sherpa's out. With all the modded bikes about what chance of winning pre-65 on a M10?

Only one word can describe the experience.FANTASTIC. I had a great time,brilliant dry track,sunny day,bike ran faultlessly. I was slow as a slug mind,the power of my 1983 Husky 250 is awesome but the powerband is like an on/off switch. I was lapped every one of my 4 races of 8 laps by a guy on a 490 Husky who was awesome,so I only got 7 laps. I had great fun though,and never fell off once.Nearly,couldn't have been trying hard enough! I would advise anyone,get yourself a cheap twinshocker and give it a go.

Thanks for the advice Dave,I plan to ride at my own pace and try not to fall off.Looking forward to it though. What bike did you ride? Pursang? My friend Graham is also debuting tomorrow on a Mk 7 250 Pursang,I have been preping it for him and had a run out on it last weekend.It has a lot more torque than my 1983 Husky though the Husky has a better top end rush.The Pursang suspension is not so good either.

Very nice looking bike. The owner seems very sure the timing side crank seal is the cause of the erratic running.It is a pretty easy job,why not spend the hour changing it,get the bike running properly and get full price for it.Is it just me but alarm bells would be ringing.I had 2 Bult's and re-built both of them but I could not tell you a crank seal was the cause of erratic running unless I changed it and it ran ok.The engine is very clean looking,surely it was rebuilt with new seals? It has hardly been used so cannot be leaking already surely. Buyer beware?

Only 2 days to go until I make my scrambles debut on my twinshock Husky.I am riding the twinshock support class at the SCRMC scramble at Forfar on sunday.I have never ridden a scramble before in my life! Wish me luck. I think I am gonna need it.

I haven't much experience of other Spanish bikes but I would say that most Bults,if they are put together properly,are as reliable as anything from the land of the rising sun. My first trials bike was a 247 Mont in a box of bits but after building it I could not get it to run properly,gave up and bought a 198b.

My boss at the garage I work says,he was an apprentice many moons ago working for his father in law.He was replacing a head gasket on a tractor engine and asked his father in law what torque setting for the head bolts.The reply was 'tighten then 'til they are just about to break'.

Specially in winter!

I use ATF in my Techno with no problems.

West Country Windings advertise they do replacement CDI units but I have no experience of them. Anyone had one from them?

My Techno was running fine at the last trial,washed it,cleaned and serviced it and put it in the shed for 2 weeks.Went to start it on a friday night to check everything was ok for a trial on the sunday and it refused to start.Had a spark but it was very weak.New stator and it started 2nd kick. I doubt if the guy you bought it from had any idea,they just go I believe,mine did. A stator from a 1999 Techno would fit,I imagine the CDI would as well,earlier Techno's were different. If in any doubt phone Lampkin's they are very helpful,especially at emptying your wallet!

Thanks. The 99 Techno has the same ignition as the early rev 3's,I believe.

Has everyone who loves old Bults seen this Spanish website for Bultaco casual gear etc ? www.jabis22.com They advertise postage to the uk though I have resisted ordering anything yet.Cash flow problems at the moment. Some very nice stuff.

I think from 73 onwards they are pretty much the same. Mail Dave Renham at Bultaco uk ,he will tell you. Do you really need to buy a whole bottom end just for the ignition bits you need? Again try Dave at Bultaco,the stator may be duff on the bottom end you are looking at.A rewound stator will give you a much better spark.

I have fitted a new stator to my 1999 Techno 200 and seems to be running fine now after a bit of trial and error with the ignition timing.I have retarded the timing about 2mm from the centre of the screws and it seems to be running ok.I will need to try a test run.Does anyone know the torque setting for the flywheel?I have it at about 70 Newton metres at the moment safely but do not want to go any tighter as I don't want to strip the threads.

Been out to the shed this morning and tested stator with my basic multimeter.Reading I have is around 260.I assume this is my problem.I have mailed Bradford ignitions,waiting for a reply.Thanks to everyone for advice.
