Classic Trials

Hi all...I'm the recent owner of an '85 Cagiva TR350 which is missing the air filter. I can buy filter foam to make up another one but I'm a bit confused as to where it actually sits in the air box. The parts manual shows a screen and a flat, rectangular filter, which must sit somewhere in the air box, but there seems to be no tabs or flat surface for such a filter to seal against or anything to hold the screen and filter in place. There is some mystery nut shown on the parts diagram which is floating in the air and not connected to anything. It would make sense that the screen goes in against the filter then is bolted down into place to secure it...but no bolt is shown…

I'm planning to put a Bultaco rear wheel on a C15. I also have the swingarm and am wondering if it may be a better idea to install that also. From what I read, the C15 arm has limited tire clearance and is improved if made longer by an inch. C15 type mounts could be welded to the front of the Bultaco arm to accomplish both. Has anyone done this? Are there other recommendations?

Hi Just wondering about the finish on the billet aluminium hubs and if it is worth while getting them anodised to protect them and keep them clean? Do many people run them without being anodised? Jonny

Hi all, im new here and new to trials! i did join here a while ago but never bought a bike until now. Anyway, i have just got a very good condition for age fantic k-roo 212cc and ill try and get some pics up. Please can anyone give me any pointers as to what to check, look out for, advice topics elsewhere and more importantly a service manual. I have a wiring diagram and thats it. I dont think i have bought a duffer anyway. It came from a mechanic and the bike is not tampered with and the guy bought it because it was untouched but doesnt use it. From what i know it needs: attention to mono shock spring rear disc sticky clutch slightly drags when cold exhaust slight …

this realy was and is a great trial. Spud, you missed out this year! cheers Lee

Hi I wonder as a new member if there are any of you out there with experience of modding the pre 9E engines . I'm hoping to get back into trialling my Norman fitted with mildly modded 8E . If we start with the exhaust I made a tidy but confused system with the front pipe crossing over from left to right around the front downtube and over the top of the flywheel / gearbox to enter a transverse tubular pot of two chambers and very short with the tailpipe blowing down onto the rear chain . Neat yes , confusing the charge I suspect so No.1 on my list; any thoughts ? Would like to keep it high level really , considered just cut and shut of standard silencer from Armours . Nex…

Hi All, Can anyone recommend any books on pre 65 trials bikes(author and/or title) please? Thanks in anticipation.

Tried the SSDT website but nothing. Cant even access the members photos so anybody know whos leading? Any photos etc ? Well ones that i can see that is

Avise needed please. Iam building a bsa bantam trials project , not for competition use . can any one advise the best way to go to replace the front forks for more modern replacements that would be suitable for trialing . I do not wish to spend a fortune and require replacements that do not require major engineering to fit . I also understand that the bantam swinging arm will not take a modern 400 x 18 tyre with out it rubbing on the edge of the tyre . Does any know how to widen the swinging arm ? Help and advise appreciated

That time of year again, many people going to the Twinshock Dirtbike show at the weekend?

Being "vintage" myself, I decided to go the vintage path in trial bikes. (Innately I asked about 90's Fantic, and received helpful information, but I think my heart is the vintage design and look) By vintage I mean air cooled bikes. I'm 6'0 tall and weight about 165lb. Looking for a fun trail bike to learn the basic and maybe in the future to participate in the category of vintage trials bike races. My main concern is getting spare parts for the bike. I'm locate in the US. From what I read the main 2 option are Yamaha TY125 or Honda TLR reflex. From the to option above- any year engine combo recommendation? Did I miss other bike option? …

A few years ago I bought a couple of brand new oval alloy barrels from a supplier who shall be nameless in the UK and fitted one to my trials Cub. After about two events it had smoke and oil spewing out all over the place and required stripping. I found that the liner had spun in the barrel which misaligned the oil drainage holes resulting in the problems I experienced. I tried contacting the supplier who ignored me completely and I would add that the supplier wasn't UPB, AWR or Armac, but he is well known around the UK. Can anyone tell me if this problem was rampant or was I just unlucky getting a couple from a bad batch, I have always been afraid to use the ot…

I haven't riden a trial for nearly 10 years now so I'm a little out of touch with it all. Which championship would be the best for me to ride on my Montesa Cota 330 (1985). According to the acu web site there appears to be 2 which I could enter. Sammy Miller and Acu Traditional?? Do any these Trials involve road work? Which would be the best for me and the 330? I presume I still need to join a local club (will join Nene Valley anyway) but do I need an ACU licenece - when I started in 1988 you needed one, they then abolished it. Is that still the case? Other than the national champs are there any good events in the Midlands for Twinshock? Thanks, Steve

Anyone seen or heard anything about Brian Hutchinson (Stokesley) - He was a big hero of mine throughout the 70's and 80's, riding Montesa's and laterly Bultaco 175's. If anyone has any pics, please post, so we can see the farming genious in action. Cheers,

Hi trial-ites, I have a conundrum... I ride a 1986 TLR200 its in good nick and almost every time I pass the garage I'm in there fiddling with this or that, making it slowly better and better. It doesn't cost much to keep going, virtually nil on fuel or oil, and replacing consumables, bearings etc are what you'd expect to do on any bike. And there's no linkage bushes to maintain. So ok, its cheap to run, Its nice looking and goes well. Here's my problem. Nearly all my mates ride modern monos. They keep saying I should chop in "the old nail" (bloody cheek!) and join them in the ranks of the banana frame brigade. I'm always near the bottom of our group in the results t…

Hi I am wondering if anybody could help me. I have just finished restoring an OSSA 250mar Mk 2(1975) and have bought a new Mikuni VM26 for it as the bike was running badly with an old worn Amal. It was hard to start and lost its tune very easily and constantly oiled the plugs However after fitting the new Mikuni VM26 it starts easy but hiccups and wont rev out when even slightly warm. The new carb has been set up with a 120 main and a 2.5 pilot but when running it appears starved of fuel. Any thoughts on what the correct jetting and settings should be? Any thoughts most welcomed Chris White

I was moving garage at the weekend and came across this cota 247 manual, if anybody would like it in pdf format i will do it for them Vinnie

Hi, I am new to trials and I'd like to get into classic trials. I have an old twin shock Fantic and would at some later stage like to take up pre65. Does anyone know of clubs in central Scotland that accomodates this line of the sport or do I join a trials club and just go along with my Fantic? Cheers

hi every body i bought a montesa 247 and its a beautiful machine but im having problem whit the oil-gasoline mix to pure on the bike tank, i wonder if any of you might know the specific mix for these bike ,im using castrol super tt 2t.. and 1/4 of a pint of oil per galon of gasoline, any suggestions?

Hello I run a sammy miller framed Bultaco which has a 1975 PM124 engine fitted. it came with a 1971 front wheel and probably the 1971 forks and clamps as well also a Montesa rear. So, I've managed to grab a barn find: a 1975 PM125 350 and will be using the forks and wheels off this to get the age of it right. alas the offset is no different between the two bikes and already the front is a nightmare when I trial the bike. the front drives on or tucks under so I reckon I need less offset (and more trail) in the clamps. yesterday at a Dabbers trial, after much measuring the nearest i can get is a set of SWMs or Honda TLRs. the Honda clamps look as if I'll have f…
