Twinshock

My SWM's drum brakes have my attention at the moment and searching for improvements to drum brakes came across a few references to using 2 pack paint hardener on the brake linings to 'pep' them up. These threads were from afew years back....and not posted April 1st. Seems the linings were lightly sanded down then 2k hardener was painted onto the linings, left to dry for a day, then sanded down again, refitted and hey presto (shazam may work too?) improved brakes....although why this should work no one knew? Anyone doing this these days? (Obviously no substitute for properly maintained brakes I will add...just curious)

I just did a top end rebuild on my '74 TY250 and it is running great. Wanting to make sure all of my settings are correct, I checked my original Yamaha 1974 TY250 service manual (Copyright 1974) for the spark plug gap for the NGK B-7ES. In the specs section, page 4, it says 0.4 - 0.5mm But on page 29 it provides 0.5 - 0.6mm as the plug setting. Trail & TrialsUK sells the B-7ES plug with the notation 0.3 - 0.4 mm plug gap for a points ignition, which I have. A google search did not provide me with any other sources. What say you, and what's the source of your info? Thanks

Hi just stripped down my Falcons off a 200 Fantic. What grade of oil would you use and quantity. Also do you have to run them with air in? why not just oil. I am 75kg and use 40lb springs.

Can you get progresive springs to fit older Falcon shocks? I have tried ringing Falcon but never any answer? will Betors new progresive spring fit ok?

Hi all, have added a Merlin/ Cagiva DG3 to my to do list, does anybody know who the UK importer was or any likely source of spares? So far I am looking for a front brake plate and a front sprocket cover but no doubt the list will grow. Thanks Giles

I posted this in the montesa forum but i should have posted it here, Hi, can you change the kickstart shaft without splitting the engine? silly question as i split a 349 a few months ago and i just cannot remember!! I have been offered a 1977 one with the splines stripped. cheers Dave

Just wondering does anybody know someone who can re-foam and recover a Majesty seat in red and white for reasonable cost

Just wanted a bit of advice on Electronic ignition. I'm thinking about fitting some Electrex World electronic ignition on my AJS Stormer and was looking for a bit of confirmation as to whether it would noticeably improve the engine pick up from low revs. The bike is fitted with points and set up 2mm btdc a the moment and does actually run a treat but I keep telling myself that static ignition like what I have can't be getting the most out of the engine. Any advice from any two stroke experts out there, I know some of you must have been motocross stars at some point. Cheers for any replies.

I am considering a twinshock bike and have it narrowed down to a TY or a KT-250. The reason for these two is availability. I figure parts will be hard enough to get so that is a concern. What positives and negatives should I be aware of for these two bikes?

Hi, As title, I have falcon alloy body shocks on fantic 300, but also have acquired a pair of rockshocks, which does the best job? Ian

Another brill trial, this time at burycliffe, near Elton Matlock, seem to get good weather for all of Paul's events, have you a connection to someone up there?? Anyway thanks for a great event, good turnout as well...bonus! Regards, Ian

In responce to the "fuel tank" repair thread, does anybody know of a company in the UK that can repair the lower side panels (Armstrong 320) on my Tank-and-seat unit as they have been worn away and now splitting apart, and respray/paint the whole thing back to it's original colour ? Thanks in advance. Gaff.

Is anyone else on the Trials Central site riding tomorrow at the Hyland trial.

Found this while looking around on a MX forum Can anyone remember anything about George Silk's trials bike, anyone ever seen one and any idea who is riding it in the video. Cheers Martin

Hi all Im in the process of buying a 199model 350 sherpa, the bike is pretty original but I would like to know the best mods to improve the bike, maybe along the lines of electronic ignition, new carb maybe and some brakes would be nice also what improvements can be made to the steering and handling of these beasts? cheers

For all you non facebook users I notice Yeadon and Guiseley DMC have introduced a new twin shock class to their Trials, along with an easier course for the more steady rider. So time to dust off those springs and get out. Good on you Y&G 😁

Ok i'm looking for any info anyone has on these bikes. Am i right in thinking they are French??? Big big thanks for any help..

Hi, Does anyone know of an alternative Kickstart lever that will fit a Montesa Cota 200 1980, it has a 15mm shaft measured on top of the splines, Cheers, Vaughan.

A short Youtube film showing a brief history of trials and George Silk explaining his new gearbox-probably from the 70's?-a 4 speed with high and low ratios.Does anyone know of these Silk machines today?Engine seems similar to the Alta Gaunt Suzuki in the previous thread,the bike like a Montesa.
