[Undersize fork seals]

I recently changed the seals on txt pro but the od of the seals supplied are undersize. They seemed to fit ok

The od should have been 52.2mm but the ones supplied are 52.0mm, they don’t seem to be leaking but I’ve not done a trial yet!

Anyone else had this issue, I don’t fancy wasting the oil to change them

 

[WAHOO-pic of my bultaco]

Looks nice 

[DIY zinc and nickel plating]

I would avoid cadmium!

 

[DIY zinc and nickel plating]

I've done Zinc plating on nuts bolts and brackets at home, with good success. but its only tiny parts I do

Also you need to be aware of hydrogen embrittlement.

[Crank bearing replacement]

Does it need the bigend replacing or just main bearings?

[600cc Desert Racer]

thats a nice looking bike, I’d be happy to swap it for my old gasgas if you want a trials bike

Brookfield garage is in stowmarket, but I've no idea on what kind of stock they have.

What i do, is try a few hats on that i like the look of at a trial (usually during a long queue), ive never had someone refuse me trying their hat on, take a note of the size and then buy online.

It would be a brave man to try on my sweaty helmet!?

Many years ago the wife kept it clean and shiny, but she’s lost interest now! ?

 

[Speedway trials tyres.]

If you put a 19" trials tyre on a bantam you would need to extend the swing-arm, and that's all that's needed to fit a proper trials tyre

Good for you

But in fairness proper gb oil is the best option

Using whatever you are happy with is a personal choice. I like the clutch action from ATF, but it’s not for everyone!

[Beta techno 250 gearbox oil]

I've used ATF if my gasgas for over 11 years, never had a single problem and it’s still on its original main bearings

Don’t autoboxes have bearings, and how much oil do most 2T mains (and big-ends) get with a weak premix!

Whenever i hear someone say "Literally heard the consequences" I laugh

Did it have a long "flex " ??

No, but It had a rather large Lucas lead acid battery?

I'm sure there could be a modern Pre65 version?

If you use a pre-65 electric motor instead of a pre-65 petrol motor it would be hard to argue against riding in pre-65 class but you didn't ask that.

If you could hide a modern EM electric motor inside a pre-65 petrol motor and hide the cells inside a pre-65 fuel tank, then it would meet the eligibility criteria for pre-65 where I live.

BSA did build an electric trials bike, there's a picture of it with Jeff Smith riding  

(See: Don Morley’s BSA singles book)

Why would I bother rebuilding the rear shocks b40rt? what sort of stupid question is that? if it was a show bike then I wouldn't worrie if there was any oil in them at all!!! you silly man!! or woman!

That’s a bit Harsh, I guess what B40rt is saying they are probably knackered. Most people just replace with new!

 

 

[Fantic 240 rear shocks]

They are good shocks, no reason to change (unless you want to give them too me ?)

[187 Alpina EATING thru plugs]

I had the same problem a few years ago, I changed from Champion to NGK and the problem vanished. (bike was running a motaplat ignition)

I was reluctant to change as I got the Champion plugs for free from work!

it was only one bike that had the issue with the champion plugs, all my other bikes ran fine on them

Plus you could sell your old parts for around £150 (if they are in good condition)

The observers at even a club trial can be swayed into not giving the correct scores as they have, at least once, had a rider if not questioning then down right abusing them for giving them a well deserved 5.  I have been on the observer end of these "conversations" and after a row with the rider who threatened me, have come close to putting the board down and going home.

 

Make a note on the sheet next to the riders number, then inform the C-of-C or anyone running the trial! 

[TXT Pro Neutral selection]

All pro's are hard to find neutral

[Old bike trailers and the law]

It weighs exactly 50kgs, so it gives me 150kgs. Just enough for a beamish ?

Just needs a few more jobs to finish, and source a spare wheel!

[Old bike trailers and the law]

I'm 99% sure its an old gracecourt skivvy chassis (Gross 200kg), but the chassis plate has long gone!

[Old bike trailers and the law]

I’ve just tied up an old bike trailer, and have replaced lights, tyres, some welding and a fresh paint job.

But it has no chassis plate, I’m guessing it’s a homebuilt or modified small trailer

Whats the law on not having a chassis plate on an old trailer?  

[Michelin tubeless tyres?]

I use tubeless on my beamish without any problems

[Having problems after replacing woodruff key]

If you have taken the rotor off it will need timing correctly, unless you fancy replacing a holed piston
