ESE's works engine tuner

[husaberg]

Have you heard Motocross? Its ruined the viewing experience. Bunch of bikes farting.

Yeah granted (spend a lot if time with the kids at MX) but at least there still is the 2 stroke shrill in the minis, Plus the MX bikes vary the revs a bit more plus bounce of the limiters a fair bit.....plus the two/four mix is sweet. But the Moto3 is drone city er....Motomonodrone

Maybe I just wait till I water cool it, I can do that on the 100. - Funny I've kept some of the rubber dampers they come with std in the past, - but threw them out as I could never think why I'd put them back in. . . until. . .

The Rubbers keep the noise down. The same reason Why Honda added them in the first place.
The quieter the engine the louder the exhaust can be.whist still not exceeding the noise limits (but you already knew that)

One thing i really want to know about is Friction minimisation

Wob has shared some worthwhile gains can be made with ceramic bearings and Teflon seals floating mains etc what else i assume the GP bikes had pressure feed gearboxes what else................

[Yow Ling]

what else................

remove seals from wheel bearings
single skinny ring
no cams
skinny rider (air friction)
tyres
plain chain

plain chain

Ok slippery goop on leathers (Tight fitting leathers).
Slippery fairing even if they are ugly (only Yams)
Plain as you say skinny but HD chain with proper one piece bushes non stamped links (the old ones were handmade) new ones ?

Gee that first yam is still ugly even now.....slippery or not.




This below is what got me thinking re friction yes its Diesel i have seen other stuff similar re F1 and Indycar and so forth.
So Read it otherwise the puppy doesn't get parole

Thanks TeeZee..

The blue print of my new and improved cylinder has been.... well er printed on the inside of the cylinder, it's been dialed in and scribed and I have my instructions, I just have to get hold of the appropriate tuning tools and I will be off and running.
Photo's will be added as i progress

I see beer and powertools. So its off to a perfect start.......


Below Kevin Vs the evil Honda mounted Eddie.
The only Suzuki i really liked. Gee Kevin was awesome to watch then. Crash or Burn (trying)

Not beer at all then.

I saw the photo and cried a little inside... At least it's not a Micrometer.

TeeZee reckoned this would get a response but do not waste your tears as they were not my good ones but a pair of Chinese $12 specials .

I know it looks a bit harsh, but sometimes you have to be cruel to be kind.



Cut down verniers are an easy and accurate way of checking port heights and for getting the transfer pairs opening at the same time.

Been away winning races so will reply now re the deto box.
Calibration is easy, turn it down real low such that the green lights do come on when doing a full throttle run.
Keep turning it up till you get a deto indication somewhere in the powerband, going up on full throttle, or as TeeZee found, when backed off on the overun.
In short - believe what you are seeing, if it shows deto on the overun, then, its got deto in the overun.
This MAY not be an issue when racing as you MAY not damage anything detoing for a short period under these conditions.
But,of course if you have a TPS this means you can use a 3D map, and its easy to pull out a couple of degrees of timing at that point, and the deto will go away - simple.
I found that maximum performance on the dyno meant you had short flickers of deto at nearly all rpm on full throttle,and it lights up when you hit the limiter.
I do several pulls at 1/4, 1/2 and 3/4 throttle,running up against the dyno load, as well as running down on the overun. to generate the TPS driven curve shape.
This enables you to dial up the max advance needed everywhere, then go into the software and back the whole curve down 1 to 2 degrees.
Now you have a good curve shape that the engine actually needs, and any issues on track, can then be taken care of by the box switching the retard input to pull out 2* to prevent unforeseen meltdowns.
I havnt used the deto setup on an aircooled, but I suspect that the deto ringing frequency signal is much bigger amplitude than a watercooled cylinder,meaning you get a much quicker indication of deto approaching.
Means its very sensitive to adjustment, but I say again, if it is flashing deto at one rpm and not at another, then believe what you are seeing, just turning it down so it does nothing, is dumb.

I haven't used the ignitech yet (still commissioning the new engine with same peripherals as previous so I know where I am). I couldn't turn the knock down enough so it didn't flash up.

I'm losing a bunch of power somewhere so I can't say that the bike is running well, but I did gain 2hp leaning & advancing the settings so I can't see it in freefall deto at the start of the session despite gauge screaming it.

Have to strip engine again, I'm losing 6hp from previous, the engine is no longer leaking but I wasn't happy with the crank & it seemingly hasn't settled in. Crank got wider with looser setting & I think its pushing on the bearings. I would imagine it would be discolouring bearings to lose that much power though. Was pushing against time.

The piezo sensor will easily show the missfire from hitting the limiter, so it will also show a big end knock, as well as the piston hitting the head.
Dont know about excessive piston slap , but probably.
Plenty of "noise" sources in a 2T.
