ESE's works engine tuner

I am not sure what model this is but Frits posted it as the last honda pipe.
Actually it appears he posted it for you on pitlane......

He has also posted this pretty extensively

Will fix it later.........

Making progress with the lighter better handling (I hope) bike.

I am aiming for 21 deg rake, 85mm trail and 40%R & 60%F weight distribution with rider aboard.

Front and rear suspension has pre-load, compression and rebound adjustment.



Now that Beast 2 is coming together it was starting to take up to much space at work, I couldn't hide it under the bench anymore, so I brought it home.

The engine is going to go as far forward as possible to get the weight on the front wheel.



The new head is much bigger than the original Suzuki one and the angle to the airflow should allow for some pretty good cooling.

The original front engine mounts will be used for securing the air cooling ducts.



Of course, there will be copper everywhere on the cylinder and head.

The head is missing from this picture but here is what it looks like.



Copper squish band and toroidal combustion chamber.

The copper plate is bonded to the alloy block with high temperature high thermal conductivity epoxy.

Your rider will love you for it. And take away that front guard. In the dry you don't need it and in the wet removing it will give you hybrid (very wet air) cooling.

Joking apart, even removing something as light as such a small guard from the front forks inertia will noticeably improve the feedback from the front tire contact patch to the handlebars. And it will certainly help cooling. I have no recent figures for aircooled engines (I try to stay away from those) but on a watercooled bike removing the front guard can drop the coolant temperature by as much as 8° C.

A-Kit pipe is what I called to the middle pipe in that pic. Was posted then as KTM and Honda Pipe used in A-kit cylinders.

My guess is the KTM GP engine is very similiar to the Honda RS

Frits beat me too it... but maybe even a beneficial tread pattern for cooling?

Well we ran up the new 300 heads. There was a small problem that I didn't have time to fix before race weekend that meant the squish went from .75 to .85. The result was a missing 4 hp. On the up side I gave my old heads to other Richard to try in his 300 and he gained 5hp. I will be pushing the squish to its limit on the next attempt. I think the engine will be ok with .7

Yes,thanks, making use of the draft off the spinning front wheel for forced fan air cooling is not a bad idea. Especially as it does not cost any extra power to do it, unlike a crankshaft fan or an electric fan or even a large scoop for the air duct would add drag.

but you still managed to happily beat him

it would be interesting to test the squish on a hot engine as I've got a few concerns with 0.7 on a piston that large...

Yeah it will be tight. Richard ran his a .65 with new crank and it didn't touch.

whats happen dave , what did it fell like before!#$@

Man Cave complete with comfy chair for contemplating motorcycles and the banana box's are full of rock LP's from the 70's for head banging relaxation. The speakers are fastened to the ceiling and the whole shebang is powered by a big valve amp that can only be described as a heater that plays music.

Pretty good. But there's no water in the rad. That might be an issue.

[TZ350]

Sorry to hear it is still giving you grief....

Anything special for page 1000 TZ ?
