I've recently bought an unused SM Highboy TY175 frame kit. I am in the process of puting it together to ride. I have have never seen another one and am trying to learn all I can about it. The frame looks remarkably similar or identical to a Whitehawk TY175, but it has a fibreglass one-piece SM seat/tank unit rather than the Whitehawk setup. Can anyone give me some leads or info about this bike? All I have heard so far is that they have a tendency to crack the front frame tubes and that the frame was probably made by Dave Cane. All suggestions welcome thankyou photos here http://www.trials.com.au/forum/viewtopic.php?f=16&t=7408

I now have all the parts to reassemble my Cota engine, I am checking things prior to assembly and one thing I am not sure about is the kick start shaft. It appears that the assembly is as follows. The shaft is located inside the engine in a brass bush, a circlip and washer are next, and the shaft then goes through the engine casting where there is an oil seal. , the outer casing and bush are next followed by the kick start. My query is should there be a spacer after the oil seal, or if not what stop the shaft moving inwards, if this happens the cam on the kick start shaft will foul the case as is kicked over rather than correct position were the can hit the stop.

I am rebuilding a Montesa 242 and although the bike is low hours and relatively untouched, when I washed the clutch case and gearbox out with petrol, what looks like thrust washer dropped out of the primary case, evidence as you can see, a ham head took the clutch apart, the nut was also loose, has anyone any advice on dismantling these clutches please? Many thanks 242.pdf

seems cool, but the engine looks overgrown in the small frame. http://cgi.ebay.com/ebaymotors/ws/eBayISAP...5&category=6719 not that I am into these, the Mont 23 look more to scale. k

I have a pair of original alloy bodied Rockshocks are they worth a rebuild ready to fit to my Cub, or have shocks moved on so much that it would be better to get a new pair.

OK, how do I place an add? I'd like to just put a link to my site so I don't waste my time and Andy's space. Like this http://metalmarkers.tripod.com/hondatrials/id13.html

The skid plate for my 74 TY250A is missing. B&J Racing has aftermarket plates, but the owner got hurt and is unable to ship. Are there other options for a skid plate, possibly from a different bike that will fit, or aftermarket that will fit with a little modification? Thank You Glenn

Hi all Just purchased a 1982 gripper 350, came with a mikuni 28 mm on it, can anyone provide me with jetting that works well for them? cheers bob

Over the past few months I've dropped an XL185 motor in aTL125. Seemed fine on the first test run. Not so happy first and second gear don't always seem to engage when the engine is running,seems to engage but when the clutch is let out nothing - no drive? Third gear is fine and the engine seem to pull very well. Any suggestions gratefully received. Thanks

Does anyone know if you can just buy the mid box separately (I already have the tail pipe) or anyone selling one second hand?

Following a recommendation I'm after some 6" High Rise Alloy Trials Bars. Who sells them in the UK?? Names & no's would be good TIA

Hello, can someone tell me, how much play/clearance/backlash between immersion tube and standpipe is permissible, or is usual (Betor-Forks). The 0.15mm feeler gage can be pushed between them well. And in another case the backlash is even so large, that the shaft seal does not fit any longer. Peter
