ESE's works engine tuner

[husaberg]

It appears that the twin cylinder Seadoo model 580 2T that takes the rotary valve drive from between the cylinders has a spring on the drive shaft that may let the skew gear float a bit which might serve as a damping device.

When Jan said lik a pommy i was thinking this, it could be the same set up but with the cam so steep and the spring that is so strong it cant go to the next slot in the cam changing the timing?

Dont consider it as advertisiment. I going to make smaller version baced on this. The first OPEN SOURCE Tuner Studio compatible Stm32 based engine management system. Unlike Microsquirt or Speeduino it is "real time" system which will allow got max of your engine.

Hello,

Do you have pictures of the v4 swissauto?

Other than the one that have seen it everywhere

For example the open crankcase

When designing a crankshaft, Lesson number one: Do NOT exaggerate the interferencefit, sometime somebody maybe want to rebuild it.
Quite disappointed now as the bolt wouldn´t move when pressing with a shitload of force(over 40tonnes).
And the material around the lighteningpockets on the inside collapsed instead.

Got this one showing the bottom/rear case, although there's a bit of the top/front case behind it.

Playing on the dyno with Cotswold and Chambers. Cotswold's new 50cc F5 Bucket, 16 rwhp.

That's indeed a good effort. Is that with the honda barrel?

Edit, oh hold on is this the one from his other thread?

Exhaust port should be what Wob

Thanks you

Have any of you guys fitted a dry clutch to a wet clutch bike or modified you bike to run a wet clutch dry.

What did you adapt? How did it go?

I knew someone who tried something along those lines on a customer's VF1000 when they were new. The dry sump was less than successful. He left that line of employment thereafter.

Didn't do but thought about it for my Derbi 50cc engines. High likely you'll need a longer transmission primary shaft, some mods to the clutch basket to get a sealing surface and a new clutch cover...wasn't worth the effort for me since you'd need quite a few special parts made (read $$$).
