You could try Paul Davies from Cambs Trials..

Yeah you can cable tie it to the wiring that comes out of the flywheel casing if needed . It's a crank case breather and i used to run mine just where the airbox and tank meet..

Its a breather pipe, it runs up the side of the frame under the tank..

Hello Bradcross have you tried Cambs trials as they do a silencer for the Yam. Paul Davies who owns the business also does quite a lot of modifications and fabrications so may be able to build you the silencer you require. Hope this helps..

Hi crankcase the 59n model was the road spec version I'm led to believe , You could try looking on Trail & Trial website as they have a chart with different engine/frame numbers for model reference.

Hello Cube, The best and cheapest mod i did on my 315 was to run Atf in gearbox eliminated the drag and transformed the clutch feel..

Hi if you remove fuel tank the coil and cdi box are next to the radiator filler spout. As for the switch it's a mapping switch to change ignition settings ... wet/dry..

Great photos?..It was a really good weekend..

Does it fire up? If not check the wudruff key or try a different spark plug..

Try Combs trials they do a lot of Ty spares and the Sy carb is the same as the the Ty..

I ride and observe but have to say that only a few want to do it..Me personally enjoy it..

Hi Csp you say its had a rebore and piston do you know what piston was used?? The reason I ask is I have just rebuilt mine last year along with two of my mates bikes ALL with wossnor pistons and they knock like a diesel engine.. My mate actually took his barrel & piston off his pinky to experiment (genuine standard Yam piston) and guess what no knocking. I have had to put two base gaskets on as the port timing was all wrong with the wossnor piston, As for jetting it's all trial and error.

The mod we used to do years ago and what I've done to my present Ty is to cut the y shaped bracket that bolts the linkage to the swing arm. You cut the y bit off a weld in a spacer a few mm thick job sorted. Also Jonathan Wren motorcycle's services the rear shock..

Hi Jake when you say you're adjusting the carb settings on the carb are you adjusting it the right way.. is your crab the one with the air screw at the back of the carb or at the front near the intake rubber(if so this is actually a fuel screw that works in the opposite way an air screw works... Check out Jim Snell YouTube videos that explains the dellorto carb and its tuning...

I will be at Buttsfield this Sunday as the northern classics has been cancelled if you want to have a bit crack.
