    Hello all. Im in need of some advise of where I can buy plastics for a project I have here in New Zealand. They need to be universal fit plastic mudguards which would suite an 80's bike, TY etc. Ive found a couple of places further afield but would like to know if there are more local places which will have a more desirable delivery charge. Thanks in advance.

    What is reconed to be the best product to line a leaking steel fuel tank? I have soldered all the leaks and tested it under pressure. However, I suspect that it won't be too long before other leaks develop. Thanks in anticipation

    Hi all and a very Christmas. I am in the throes of Building a RE Crusader trials bike and having got all the parts off the bike that I don`t need I`m just a little concerned about the width of the frame at the point where the seat will go. Is there any practical way of narrowing that part so that I don`t have to go bandy-legged to ride it? I have tools and a welder I just need a good idea. Many thanks, Hazel

    Hello all, I recently bought a Royal Enfield Crusader 250 which I am going to make a trials bike of. Mechanical stuff I am fine with but am a complete dunce when it comes to electrics. What I want to do is convert the electrical system so that the engine provides its` own sparks. There are 3 wires coming from the back of the engine that originate at the alternator, can any of you please tell me how to wire things things up so that a battery is not needed. I have the rectifier but no clue as to where to start or what to do. Any help would be great.

    Hi all, I`d like an opinion from some of you knowledgeable types. Re the bike in the photo - do any of you think it would make the basis of a good pre 65 trials bike or is it just too far "out"? Any comments are welcome.

  10. Hi I want to remove two rusty, seized 6mm exhaust studs from a 45 year old Honda 4 stroke alloy barrel, as I need to install longer ones. I have soaked them in WD40 for 2 weeks. I have also heated the studs to cherry red. I then tried turning them, using two locked nuts, but they won't turn. I am afraid they will shear off if I put any more pressure on them. They are not currently snapped off, so I don't need to drill them out. However, I do want them out. What to do? Anyone have experience of doing this? Thanks

  11. Started by stpauls,

    Any experiences of DIY zinc and/or nickel plating at home? Plenty of videos on YouTube. Success or failure? Tips and hints appreciated. Early Sammy Miller High Boy frames. Chrome or nickel? Can you nickel plate over chrome? Can you nickel plate over old, sound nickel plating?

    Anyone planning on riding the new series starting with the Golden Valley Cotswold Cups this year ? A worthy replacement for the Miller rounds, I'm really looking forward to it,a decent set of classes and some excellent, well established trials such as the Sam Cooper and the Greensmiths. A set of road based trials where old bikes can have a day out.

    Hi all, does anyone out there in the classic world know where I can get a replica Ariel HT trials frame from. Everyone I have contacted has either stopped making them or put the shutters up for an unspecified time as they are busy. I`m not afraid to pay but I just can find a source. Any help would be appreciated.

  14. Anyone know what bearings or bushes Sammy Miller used in his Honda TL 125 Hi-boy frames, around 1979? I have yet to take it apart to find out what's there. Thanks

    Hi there,l was wondering if anyone could help me with the optimum port timing in degrees for the Villiers 32a motor for trials, both opening and closing of ports.I am looking also at exhaust header length, is there a formula that may apply? I notice quite long headers in various vids. Thanks.

  17. Started by stpauls,

    I want to rebuild the wheels on a Honda TL 125 (150cc SM conversion), in a Sammy Miller High Boy frame, whose chrome (nickel?) plating is mostly still in excellent condition. Going to do it myself, along with many other jobs including patching the fuel tank and replacing the kick start ratchet mechanism, as necessary. I also want to polish all the alloy bits, including the hubs. Stainless or standard spokes? The cost seems to be at least double for stainless. It will be ridden in Classic trials a few times a year. Any thoughts?

    I have been considering getting a Spanish twin shock, from the 70s, to ride Twinshock Trials. Which make is likely to be the most reliable? Usable? Trouble free? Spares availability? Anything else? Any comments and advice welcome and appreciated.
