Ken, you will have to trade it on a TM now😆.

[Flettner]

At least TM are good enough to send me one😆.

I'm happy for you, Neil. By the way, how are TM-gearboxes?

[Flettner]

Haven't sampled it yet. Do they have a problem? It is just a 125, interestingly.

I don't know about any problems. I was asking because you always seem to struggle finding Yamaha gearbox parts and I thought your Italian friends might have a solution.

Vforce Reed valve on Honda Nx4. Breaks every 2 races. An idea ?

turn the little metal bar which keeps the plates in place around (set stiffness from low to high).

That is pretty ugly. It looks like something is not agreeing with the resin. I had heard that V-Force may have changed resin at somepoint over the last year or 2. We were having some problems with reed delamination/chipping about a year ago but nothing to the extent that you are seeing. Today we are still getting some chipping at the reed tips.....we are running methanol not gasoline.

wob you can see the cooling will be complete shit but since its not a road going petrol engine im not losing any sleep over it. with a small bit of grinding I got barely .5mm air gap between the cyl . just have to weld on the water bungs then off to the machinist and straighten out the decks

I found this yesterday but it gives some idea of how much flow is reduced with elbows in the cooling lines

V force told me their reeds were not compatible with ethanol, perhaps its the same with methanol.
You need a steel rotary valve😆

Well, given that methanol is normally more aggressive than ethanol to epoxy resins, that's most likely true.

Drop one of your broken ones in some of your fuel mix. Post pics please.....

hey guys on the yami twin theres a small hose from the head to top of rad. im guessing this is a self air bleeder like the bleeder screw found on most other heads. what im not sure of is if its only purpose is just for the first time the system is filled and after that its useless. ?

I have something similar on my bike. It continuously runs a small amount of water from the head to the radiator and takes any evolved air/gas leakage with it. As well as being easy to bled the head, it Leaves me confidant I am not going to wind up with an air/gas pocket at the back of the head. It is a piece of mind thing.
