    Hi, I've been trying to contact Fred in NZ through his email address but haven't been getting any reply. I've not dealt with him in a number of years and was just wondering if anyone knows if he is still in business, or has anyone ordered parts from him recently? Thanks Ross

    Hi guys, I've just fitted a Gremica 125mm front hub to a Bantam to try to improve the braking power over the previously fitted Montesa 110mm hub. The hub had very little wear, max dia was measured at 125.5mm and surface was free of any damage, I used a new NOS brake plate and cam assembly with oversized shoes arched to to fit the hub. The lining material was recommended by Villiers Services to be the best for trials. I also opened the brake plate spindle hole 0.020" to allow the plate to centralise with the brake on before tightening the spindle. Now what I expected was a significant improvement in braking power but in fact the braking is no better! New wheel beari…

    How long the front fork springs will last? I don't know the correct English word but I mean that how many years they work well before getting worn out, slack? What do you think about the front forks with fork top nuts inc. pressure relief valves? Are they much better than standard front forks?

    Am looking at purchasing the Pirelli MT43 tire for my vintage Ossa. Was wondering what would be a suitable match for the front. Also, may sound stupid, but how important is the front tire, as far as performance and $ are concerned? You can spend $25.00 - $100.00, for a front tire. Just curious what you folks think.

    Tyre discussions appear never ending but that is probably due to the continued variation in costs. My TLR 200 has I think the original dual purpose block pattern (can't remember that make and it's raining too heavy to check) The old tyre is hard and cracked so I guess it's time to replace it. I have Michelins on my Cota 247 and it does ride nicely but when I inherited the TLR I never envisaged it would be as competent as it is and so I went for a VeeRubber tubeless on the rear - what a bugger to fit that was - but it has given me no problems and good wear running around 7 psi. I am not a competition rider - comps are all held too far away for me to be bothered ( the…

    Years ago when Mick Andrews was riding for Yamaha he developed a fuel injected bike. Can anyone remember whether he rode it in the Scottish?

    Hi All, We finally got our Ossa TR 350 out on the rough stuff at the excellent Eboracum 2 day Charity trial, My son Scott rode it on the Saturday only and for just two laps but we had a great time and the bike performed quite well and got lots of positive comments from the other riders / owners. One problem pointed out to me was the bike was running 'Rich', at the risk of proving how un mechanical i am can anyone tell me how to adjust this, also I am mixing Oil to Petrol at 75cc to 5lts is this correct. Cheers, Vaughan & Scott.

  11. Started by old trials fanatic,

    Wonder if any of you have any helpful suggestions? The rebuild on the old 349 Cota is progressing slowly, too slowly to br honest as i would never have guessed parts would be so hard to come by when i started. Still we live and learn. Time came on Sunday to see if the rebuilt engine would start. You know the routine. Fit tank, fit all new pipes, fill with fuel, get ready to kick the thing into life (hopefully),turn petrol on, press choke. Notice strong smell of fuel, get wet foot, panic!!!!! Take off tank, drain tank, curse profusely all because the b****y petrol taps k*******d and p*****g fuel every where. So does anybody have or know the whareabouts of a new fuel tap to…

    Sorry if this has been asked a million times but when using modern synthetic oil do you use a bit less or does it muck up the mixture? So basically what ratio for the old Mont. Thank you.... Steve

    I have been offered a 323 Garelli twinshock with a HIRO motor. I know these bikes are few and far between and I know also that HIRO parts are scarce. Any feedback on that? Is the kickstart shaft really designed to break after 376 starts? Are spares available? The bike is complete and has not had a hard life but it is also quite expensive at 1600

    I just won the E Bay auction for a former Donato Miglio works Garelli Trial 320. I am very excited to get my hands on this rare and interesting bike. I wonder if there's anyone out there who knows anything about them or has one? I searched the web and found a guy in CZ who is looking for kickstarter parts. I am certain the kicker mechanism is a weakness of this machine. I will be trying to resolve this problem enough to at least ride the old girl a little bit. Heres a picture of the beast. Sincerely, Jay Lael.
