Try Alan Whitton,(01246 419805)it's not a job for the amateur or for the semi-pro for that matter, quite easy to end up with shiny scrap metal on the floor next to the lathe. He did a great job on mine, and many others no doubt
You still don't say what suspension your bike has, just that it fits into the appropriate sub class..
Maybe because you wrote the sub class regs ?
Why are others bikes modified in ways that tear the sport apart, but you having non standard forks / shocks is a "sensible decision"?
Let's face it, if you haven't got steel rims, bars and levers, it's because you chose to. Most back in the day used the heavier stuff,its cheaper, tougher and easily available so you've consciously decided that' it's ok.
I love to see the big bikes too, I agreed with the previous post as it made me laugh when this debate was getting po-faced, and I hoped it might prick your pomposity a little.
Your 'fantasy pre-65' regs throw up as many issues as they solve? Last year I sold my dead stock Ariel HT ( ex Bob Eyers, I'm sure Deryk would have known him?), now if I was to turn up on that to one of your trials, I'd be immediately disadvantaged by its steel rims and bars, original poorly damped suspension, standard pegs etc.
Now steel rims and bars are easily available, levers too so why choose the mods that suit you?
Can you explain why electronic ignition offers enough advantage to get moved out the class, but having say TY fork internals and nice damping front and rear follows your pre-65 rules? Suspension is a lot easier to scruitineer than ignition too.
What suspension do you have, out of curiosity? I'll guess a purist like yourself has original shocks with 50's spec (lack of) damping? Do you run standard ( to your bike) forks too?
Replica frames are ruled out too as no replica frame is ever as heavy as the original. I'd rule out tubeless rims too, as compression punctures happen much easier on 300lb bikes than 200lb, so the tubeless folks will get away with much lower pressures.
And please do away with the hissy fits and fake indignation, the guy from the Yorks club offered reasoned arguments based on his experience, and you reacted like a typical Internet keyboard revolutionary
"It's a different world, so making comparisons with 'the way that it was' is just not possible."
So why keep on doing that then ?
A sport involving a finite number of machines getting older and older each year is bound to naturally evolve over time, just because that evolution is not to your liking doesn't make it wrong.
Are there really scores of pre unit big bangers sat in their sheds waiting for a suitable trials series? Pre 65 in '72 was for bikes just a few years past their sell by date being ridden by blokes who'd grown up with those sort of bikes.( hence the growing popularity of twin shocks and air cooled monos now)
Surely the fact that 40yrs later people are still interested in pre 65 shows that it's not all gloom and doom, most don't ride £10k bikes after all..?
As for people entering the sport thinking they can buy their way to the top, surely that's the same for every type of mechanised sport or hobby.
It's not a pageant of how it used to be in the 'good old days' , you can't buy an HT or comp Bullet for £500 and ride it to the event, and would you want to !
Are you trying to protect the engine from a dirty oil tank? Any debris or particles come out of the return first anyway, if you put the filter on the feed, the oil tank will be full of crap out of the engine. Surely you want the oil cleaned as soon as it leaves the sump ?
I used the one Dave Varley at D & C Classics sells, very compact and uses Enfield filters ( I bought a job lot off EBay). On the return line as the inlet is gravity and suction, but the return is pressurised
