section swept

Looks brand new, very nice!?

That is a seriously rare bike! If memory serves me correctly both pistons fired at the same time rather than alternately.

He who built the Arrow engined Drayton?

?

Location is quite some way in land....looks idilic ?

What I said!

Dougie late for the start of the ISDT....it’s along way from parc ferme to the start? Note he’s wearing the latest Jitsie riding apparel??

Did you set the valve clearances correctly? Were they done hot or cold? The cam chain tensioner spring can become weak even though it feels ok to you. The noise of your engine does sound very rhythmic as though it is tappet noise. I would go for resetting the valve clearances very carefully. Also fit a new tensioner and spring to be on the safe side. Follow the setting procedures for both from the manual. Keep us posted please.?

Isn’t that supposed to make a knocking noise!

Will be organising a coach party, how many can you put up for a week or two??

Video with sound would be good and £34 for a simple puller is a bit steep. Are you sure the mains have gone, can you move the crank about from side to side by pulling on the flywheel?

Main reason for altering the footrest position is to anable the rider to stand comfortably in an almost upright position. The original position if you look back at the professionals riding they were using their knees far more and were perched on the bike and could flick the bike from side to side quickly. They could also move their weight around front to back and also the foot rests being high compared to the new thinking were out of the way of rocks etc, most being designed to spring back and up unlike the new rests that tend to just swing up. The old rests were a bit bendy so a clout from a rock bent the rest rather than throw the rider off the bike. It is usual to position the rests down and back but no further down than the wheel spindle line of sight. If you drop a plumb line from the swing arm pivot this usually indicate a starting point for the new location. Note this does not work on all bikes so experimentation is needed. Another point to bear in mind is the fact that quite a lot of the old guard ie Miller, Peplow, Smith etc were not tall people, whereas Andrews was a large framed person, so a close study of works trials irons of the time may show up slight alterations not immediately obvious to the casual on looker. When you have repositioned the footrests you are more likely to clobber your feet in tight sections, but with the broader platform and heavy serrations you have better confidence feet wise and a bit more control if you are a hoppiest or bouncer. Jiggling the bike about for best angle of attack! The rule of thumb in earlier trials times was to keep the bike as upright as possible and use body weight transfer to steer the bike. Whereas the new thinking is to use balance and bike positioning to obtain the best steering and drive. Me, I prefer the original positions, but when you look at the latest trials machines there is only one place to position the rests, but then the geometry of the bike is totally different to an Ossa of 1972 or any other bike up to about 1989 ish.??

Very nice TY250 very standard looking too....nice??

Take the forks out and obviously both wheels. Remove the fuel tank. Now using all the skills of the Man from Uncle quietly sneak everything into the house and hide the bike in bits under your bed. The fuel tank you can either fill with diesel and place in a box and surround the tank with bubble wrap and blankets....fire hazard....so store off the floor and away from potential sources of no common sense. Alternatively you could ask a local store to use your bike as an advertising window dressing...Father Christmas riding a TY250 ...choose the store carefully one that keeps the thermostat turned up when the store is closed, you may even get a hire fee! Seriously, cover with breathable covers, leave the tank to dry out spray in silicon fluid and refit the filler cap. Pump up tyres to 20-25 psi. Slacken the brake cables off. Plug the exhaust tail pipe, rag will do. Remove air filter and stuff an oil soaked rag into the air box, put the filter into a pplastic bag. Remove the spark plug and spray in silicon fluid, refit plug straight away. Make a note in your diary/ calendar each month to remind you to check the bike, every other month you’ll want to re-apply the silicon fluid and check the tyres. You will also want to do the tank as well. The thing to do is remember that you parking the bike for winter, not totally ignoring it. A gentle loving wipe over of wheel rims and frame etc is a good thing......of course if you were the Man from Uncle you would be able to just reach down under the bed and get that reassuring feeling that you beloved is snug and warm....then you can check the wife/girlfriend....or erhem!?????

Does sound a bit rattle, as you have pulled the cam chain tensioner and confirmed it’s working the next move would be to re-set the valve clearances very carefully. The problem could be that the valve stem heads have worn. The noise is so regular that the cam chain may be the cause.The cam chain guides can wear as obviously can the actual chain. Don’t trust that tensioner it can look ok but the spring can go weak and there in lies the problem, re adjust the valve clearances and go from there. You can remove the camshaft and most of the valve operating gear without taking the engine out of the frame or removing the cylinder head it’s fiddling but doable?

Excellent idea ?

Very nice, you are a credit to the pastime that is Trials bike modifications?

The Yamaha TY 175 is a nice bike if you get one that’s in good order. Some get chopped about with steeper steering head angles, repositioned footrests and other stuff so do your research. When totally standard these bikes were tough little trials bikes and were non threatening in that the engine was not that powerful....a good one is a good starting point. Bit like comparing a Suzuki Jimmy to a Landrover swb. Now depending upon which Fantic you go for opens up a vast array of machinery, much of which is very good. Bearing in mind that engine sizes vary from 125cc, 156cc, for the most common and then the engine sizes go up slightly for the models so ignore what the sticker suggests ie 240 it’s not a 240cc Motor but a 212cc, there will be a Fantic owner probably correcting my knowledge. Fantics were good to go straight out of the box, but by now many will have been messed about with and altered to make them more competitive. I have to say that the TY 175 was good to go straight out of the crate too! I sold quite a few when I was a Yamaha Dealer, also converted a few to Majesty which might be your best bet if you have deep pockets. Either way you’ll get sound advice on this web site and you could give the classifieds on here a look....enjoy?

That won’t stop them blasting your ears when they get a bit older and don’t go to bed early?

Possibly what the cleaner knocked up with parts they found lying about.

Now calling themselves JGAS actually says this on the TC page. More than likely the EU (bless em) have provided funds probably from UK’s contribution to keep the firm going. But any trials bike manufacturer in operation is better than none!

Montesa then it is?

Set back too far but that could just be a quirk of the photo. You’ll probably end up moving them and the levers to a more comfortable operating position for standing up all the while....it’s a Trials thing. A lot of riders have the handlebars (part that you hold), in line over the fork tubes. This puts you weight over the front and gives more control when turning left or right. Have a good look at some other trials bikes and some riding training dvds/videos will show you how to set up your bike.

Crikey, there’s hardly any where to stick the latest sticker’s. Now we all know that without the latest updated stickers on that no trials bike will be half as good! So who needs Ohlins there are other suspension manufacturers ?

Just like you have found all the bits you need are available in the UK and Europe. It’s the same for us when looking for that special part or items that are only available in USA. A bit tit for tat really. You are lucky to have chosen a bike make that is very well supported.
