Is it an air screw, or a petrol screw ?

Very impressive, George Greenland must be a good age to ?

I thought you told me you took out the two grub screws & it turned into an SWM which is going to appear this weekend ?

Andy Any way I could customize the trials calender for my personal/local choices ? Just a thought. Ross

Has anybody mentioned cleaning your air filter ? If really dirty will make bike run rich, which will help to foul the plug.

Thanks Martin

The Marzocchi might give a more "modern " position !

I've driven a car up that "special test"

You can get the 18t engine sprocket here, see details re engine casing ! http://www.trialsbits.co.uk/product_info.php?cPath=85_182_257&products_id=689 Incidentally I use 15 / 62 with 428 chain on the B40, some clever person will be able to work out if its the same as 13 / 72. But has the advantage of a slightly smaller rear sprocket for clearance. Ross

Is that top yoke original ? Marzzochi are further forward aren't they ?

If you look at the history of daisy3279( 39) its per una clothing and wet look pvc leggings, pretty sure I would remember a midget in PVC trying to start a 500 Norton !

I was told the 125 had a different crank, flywheel etc ?

Hi Brian What are you looking for ? Ross PM me if you want.

Perth are running a trial at Comrie, suitable for pre-65 / twin shock. Anybody going to ride pre-65 ? Ross

I think the difference is a cut thread removes material, a rolled thread squeezes it to form the thread, ie no material lost. The nipples are obviously designed to accommodate. If you use a nipple on a cut thread there is little contact / strength.

You could run a die down to help calculate the length, but not for the actual wheel build. Spoke threads are rolled, not cut.

Norton Road Holder. Must be good as every Pre-65 has them, apart from mine.

If only !!!!!!!

Which other events should I not miss this year ?

Can anyone name 7 pre-65 trials in Scotland ? 1 The pre-65 of course. 2 Highland 2 day. 3 Perth & District & Scottish Classic have been making an effort in club trials, & Abington. 4 ?

Is it my imagination, or have those footrests been moved back a smidge ?
