But, the sections become harder & harder to take marks from modified bikes, leaving more original bikes and riders at a disadvantage. This must lead to specials being entered in the appropriate class, or maybe a handicap system. (sure that will be a popular suggestion)

The pump for pressurising cycle forks/shocks is good for at least 120psi and has a built in gauge. These generally fit onto Shreddar type valves. The pressure can be fine tuned with the pressure release button, again built into pump. All this assuming your shocks are suitable.

It's reproducing the "patina" that elevates the cost !

I only ever used 90 in the gear box once (during a cold winter) turn my 325 into a 250. Use 20/50 without any problems.

I'm curious why the Scottish Pre-65 and its organisers are constantly criticised for not applying their rules to the letter, and yet no one seems willing to put names to all these "cheats" entered on unsporting bikes. They must know their bikes do not comply, either in spirit or reality.

Remove the gold anodising on the wheels ?

Strip & clean carb time.

Is the plug wet ?

Are you getting a spark ? Is the plug wet? Have you tried disconnecting the kill switch ?

Trouble is, you open the rules to make it more accessible and cheap. But what would probably happen is the opposite, if you want to be vaguely competitive, that is. Have these forks been repaired ?

I to was tempted to put my finger into the upie downie bit on a sowing machine, the nurse was very understanding !

Tom Colour is not a problem as cases are black anyway, presently repaired with sanitary silicon ! Ross

Like the exhaust, much nicer than the more common horizontal. Is it home made ?

Thanks Tom I have oxy/acet, but a bit nervous at putting it on magnesium alloy ! Ross

Traction control, not such a bad thing ?

Hi, what did you repair with it ? Also what sort of torch did you use? (I watched the video, they always make it look easy) What length were the rods, roughly ? Thanks Ross

18 to the gallon, you should be ashamed.

You tempted fate, didn't you !

What colour is the air filter oil, might just be excess pulled into the carb.

You haven't been artificially inseminating it have you ?

That u George ?

ACU - SACU see the differenced ? Never going to happen !

Didn't work for Boy George.

I also enjoy MTB's but think without the Forestry Commission / Park access, (denied to motorised sports, generally) mountain biking might not "win hands down!!!"
