Hi all,

itīs quite funny, that we start a discussion on tuning right now, because
Iīm working on that subject since a couple of weeks.
I agree to the results of Martin, concerning the "conservative" tuning:
Using K&N filter and Dynajet improves throttle reaction, but is no
breakthrough...
Strutzenberger doesnīt sell the camshafts seperatly, he wants to sell his
"Kit". I found someone else, who is specialised in tuning of this engine.
He does long-distance races with Honda Hawks, which has the same engine as
RD04.
This guy told me several things:

1) There is no way to increase the Cylinderīs Volume without dramatically
reduce stability.

2) You cannot get a torque "punch" at low revs without increasing ccm.

3) The only way to improve power and torque without loosing to much
durability is 

	a) Reduce(!) ccm by grinding cylinders
	b) optimize channels and valve-seats by polishing
	c) change camshafts
	d) change exhaust

He sells tuning-camshafts and does all the necessary work on the engine.
The price will be ~2500.- DM, including all work and all parts.
Because he does this as a "hobby", it takes a while. He told me, that he
needs aprx. 3-4 weeks, until he is ready. Thatīs the reason, why we start
this project in November...
In advance, I ordered a "Shark" exhaust, which will arrive within the next
14 days. This thing should increase power and torque a little bit, and
sound a bit more...
As soon as I have gathered some experience I will report.
If any of you is interested in further information of the "engine-wizzard",
let me know. Perhaps, if a couple of us ask for his support, heīll do it
faster and cheaper...
