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.

Pass? If you put the wossnor pistons and standard piston together (using the gugeon pin) the wossnor piston has a taller crown..

No... the carb I tried was off a used pinky couldn't believe the difference in performance. What we have realised after getting the barrel rebored with Wossner piston the port timing was wrong. I have had to put two base gaskets on to compensate for this?? Also two of my mates have had to do the same.. I

Hello mate, I have had the problem of bike running rich off the pilot for some years now... I didn't realize how bad it was until I tried a different carb off my mates bike runs perfect all the way through rev range. I have tried pilots from size 36-42 with no joy. I have tried the Kihien flat slide but a pain to set up so put Tk back on.. If you want to send me a pm with your number I will gladly pass on some of what I have tried.?

Hi Tom did you remove the flywheel or did you just check to see if it was spinning on the end of the crank??

Try the woodruff key

Hi Drca, I have recently watched the Jim Snell video regarding the tuning of the dellorto carb. He states in his video that the factory setting for the fuel/air screw is 3 turns out for the factory setting. The video also shows you how to check if your floats are bad. Try searching tuning dellorto carb.

Hi whatmore, They say its a non serviceable unit but there was a guy on Facebook who actually did his own. Is your shock just bottoming out or is it actually lost all damping+rebound. if it's just bottoming out just slice the bottom bracket off where it bolts to the linkage and pack out with a few mil of steel plate and re-weld,did this on mine and sorted the bottoming out problem.

Here is a photo of the next project when I finally get round to building it as it has Been under my bench for a few years now. Its got the shortened inlet mod and a new pink mudguard which I purchased from Ctc.

This is a picture of my Ty which is road registered.

Hi Caddy my 315 frame has been polished if you send me your number I will send you a picture of the end result.
