There are a number of things I have not seen an SACU official check in a long time John eg noise, approved tyres, ball end levers but I nonetheless comply with the rules. However I would suggest that the rule on pump petrol did not foresee the current situation but was really intended to outlaw "performance enhancing" fuels, though must have an environmental aspect too.

If you remove the exhaust pipe you should be able to get a sufficently accurate measure on the bore size. Failing which take the head off and measure it. I can't see the picture on the system I am on at the moment.

I can jump in here on the Doblo question. The bike goes in diagonally with no seats out (front wheel to the left of the single rear seat). If you take out a seat then you can drop the front wheel in to the rear footwell and get the bike fore and aft against the side of the car (or remove both seats and fit two bikes like this). Seats are held in by two bolts so it does not take long to undo them, once you have initially removed and greased them.

Apart from such stuff probably being hard to find in the UK, its use is not permitted under ACU rules which, if I recall correctly, only allow the use of standard pump petrol.

I used acrylic model paint on plastic stickers and it worked OK.

"Well fabricated" but doesn't come near fitting the bike? Send it back.

Tyre = correct Tire = two nations separated by a common language

I think "Location: Northern Ireland" is a clue to where "over here" might be.?

I didn't see any reference to sales volumes but 250cc was the lower limit for the first period then to include sub 250s later.

I was at my FLD looking at the new Bonnie and said dealer mentioned that, as of next year, all motorcycles must have anti lock braking. A quick Google seemed to confirm this. Can anyone in manufacture/import say how this will affect the ability to register a trials bike or will the SSDT become "used bikes only"? Is the ACU aware of this one?

I don't know if many ran their trials bikes on Cleveland Discol which seemed to be the main culprit but I don't know how the percentage compares with the new stuff. But you are right, it should not be beyond the wit of man to produce ethanol proof fuel systems on vehicles.

It hasn't just become a problem. See those alloy Bultaco tanks, they were used because legislation was brought in outlawing non- metal tanks on motorcycles in the UK. This was brought about by the effects of ethanol on glass fibre tanks commonly fitted to cafe racers allegedly resulting in weakness that caused fires in a crash. Who knows how much of a problem it really was but once the press got their teeth in to it with "ton up fireball" type headlines something was done about it.

Very interesting article by Jim Snell in the latest issue of On the Pegs - he visited the factory for the start of production and saw/photo'd details of the bike both internal and external. The bike seems to be not only built to last but also designed to be easy to work on. Perhaps worth sacrificing a few bhp for? There is also a simple means of softening the delivery for slippery going.

Ah well.....I'm afraid it was the analogue version I was reading in Tesco.

I see Motorcycle News, that well known authority on trials, reckon it would be competitive in a National. Maybe if Toni was riding it.

Maybe not, but it still has to be of merchantable quality and fit for purpose to comply with trading law, which is a bit stronger than a warranty. If it is sold as a competition motorcycle then it has to be suitable as a competition motorcycle.

Not so. One bike fits in a Doblo without any seats needing to be removed. This may also be the case with the later, longer, Berlingo. And even if you removed one seat in the Doblo that would still leave four seats.

Most of them seem to have gone that way. You'll note in the photo linked to above that the 531 sticker is on the steering head. Maybe that's the bit made of 531, the downtubes on mine were apparently not.

Looks very like the Sammy Miller frame I had but as the downtubes haven't yet cracked it may not be?

I was going to do the front two - the rear two had already been fully taped over by the previous owner. .

Ah, thanks. I had noticed the rubber but assumed it was just reinforcement as the previous owner had not "used" it so I have just carried on that way. I alternate it with an Apico element (using the cage) which is all foam and both seem equally good at sealing the airbox. Given the amount of muck that reaches the area, much more than on my Rev 3 for example, it is well tested. And yes I have sealed the gap at the mudguard.

I have seen similar references and am puzzled. My cage just lifts in and out with the foam as easily slotted in to the metal and the top screwed on. Perfectly straightforward. Has mine been altered from standard then?

Hadn't spotted that but there is a difference in when a bike is deemed to be out of a section with the AMCA being very poorly defined in comparison.

I can't help directly but I would have thought that with modern componentry somebody could design a direct lighting setup for you if the battery is "required" with tbe standard system. Loud horns intended for bicycle use are available, if not cheap.

Bathroom scales, front wheel, back wheel, add the two.
