I hate to be the one who says it, but that is MEAGER for what you did... mine does that with just the Techlusion, Akra Exhaust, Remus Headers and the Foam Air filter.... nicely tuned, though.

An did did NOT tear half the engine apart... nor am I running $10/gal race fuel.

Fun project... but from where I stand, not worth the time and money... but then, you did have a nice little winter project!

Excellent.

Dates should posted soon. Probably end of May or at the latest, the beginning of June.

I think after the previous throw down we should do a Pinks run over the App Gap.

Hey EZ, do you know how much gain the 1150 upgrade got you on your s? I was thinking about doing that as a future up grade.

Dont be a trouble maker! PdiddyFog!

We both know that WST is all about the Tiki parking lot. That's were the real action happens.

I was wondering when you would piss on, I mean pipe in. Lighter spinning parts don't necessarily add up to more HP. The Wossner pistons are 12.8:1 compared to the stock 12.5:1, so I wasn't expecting monster HP gains from that little bump. What is different is how fast it revs, so while the overall number may be the same, my engine is getting there faster, and that makes all the difference. I didn't run race gas either, it was Shell 93 octane, with whatever percent ethanol they put in around here. As far as being worth the time and money, for me it was worth both. To each his own.

Why would I want to do that, I don't want any of your bikes!

[bacn5]

Thanks for the dyno update... The torque numbers would be helpful and also explain your "seat of the pants" improvement. This continues to be a great thread!

Yeah, how does THAT feel?... Not like you would ever do something like that, eh? You need to get a dose of your own medicine every now and then...

It still is a cool project, and I would not doubt in a second that that thing spins up one hell of a lot faster than the stock motor... I rode mine again for a longer trip today - after an almost 4 months neglect - and boy, it spins up plenty fast! I can only imagine what yours does...

I assume the biggest advantage to the mods I have made is that the engine revs quicker, and that I can definitely feel, but I dont think that shows up on the dyno, unless you add a time component.

Hmmm...

M-TEC claims ~140 rwbhp > that's + 20....but to tell you the truth I'm a bit skeptical about what M-TEC claims (in general).

Note the "flat spots" and compare the well known (LINEAR) diagrams from that Kurt Roesner...."some" difference I confess.

Other than that...obviously 100% TPS dyno graphs are rather useless in real life (and especially for a boxer type of low revving motor).

"Mysteriously" not many tuners care about giving 20, 40, 60, ...TPS graphs (VS stock). This is my personal target with a Rapidbike Tuning bike apparatus (kinda a data logger/re-tune gizmo for tracking the engine performance in real life/roads etc etc).

The whole problem with our old motor is to deliver as many ponies "as soon" as possible NOT in 100% TPS (in order to prevent braking the boxer in 1000 pieces).

[peter f]

PS: with regard what M-TEC claims about the stock boxer

Eine neue R1200S bringt am ersten Tag zwischen 118 und 120 PS Motorleistung auf den Leistungsprüfstand

....well, assuming that "Leistungsprüfstand" means some dyno thing (and not crank power)...I have "some" bad news fellas (DIN, correction step 2, near by the sea, 24oC) > not much the north side of 107 rwbhp I'm afraid...

[signit98]

Peter, they refer to crank power and yes, it means dyno

[Bob Hancock]

From what I understand you get torque with rpm and to get that just clip the thing on the primary sparkplug wire.....easy as pie. To get the rpm on Special K I had to remove plastic and find a plug wire up under all that mechanical mystery and clip it there. With no spark input all you get is HP at MPH.

[peter f]

Ralf,

Thanks for the clarification. That brings the next question > from 107 to...M-TEC 140 (brake rw ponies) it's rather a looooong way north. How's possible?

[signit98]

I don't think they refer to RWHP, do they? In Germany (at least from what I remember) the stated HP is always Crank... some rule they have to follow (or at least, had to).

But, in case they DO refer to RWHP, I am not buying it... you know how much work Chris and his crew had to do to get anywhere near that number on the HP2S???

[JonyRR]

I don't havea dog in this fight, as so many more factors determine who's fastest at the end of the day.

HOWEVER, for comparitive HP numbers between bikes to have any real validity for me, the runs need to be on the same dyno, the same dyno setup, the same software, the same dyno guy and preferably on the same day....two identical dynos of the same manufacture will still exhibit some variance.
Dyno numbers are like penis size; some folks need the numbers to feel secure, some don't care as long as the performance is there....nothing WRONG with dyno numbers but they're mostly propaganda

[jduke]

Shreddr, Ralf reminds me of the schoolkid who always had the newest and best of everything. When someone had a toy better than his, he would find fault with it. But it might be the peter complex Jonyrr was talking about.....

[signit98]

Jerry, whatever you do (or did) as a job, I hope it does not involve psychoanalyzing people... you are not very good at it.

A little while ago when someone did a nice job with something - I forgot what it was, not important, anyway - shreddr was the first (and only) one to come and piss on this guy's parade with one of his pointless and stoopid comments... I just returned the favor!

It does not matter what I respond to, it usually has nothing to do with who has this and who has that... I never buy new, nor do I buy the latest and greatest... I buy what I want, when the time is right... I have what I want, I am happy with it and I gladly share. The people I want to, know that... the rest... I don't care about. It is as easy as that.

I respond to things that tickle me - whether that be Bubba, regurgitating something that has already been ridden to death or that is so blatantly obvious that it does not need to be stated... or shreddr who only accepts things as good when they fit in his mind...

Yes, I do stir the pot... but then, the things I use to stir are handed to me on a silver platter... why miss a perfect opportunity to have a little fun? You don't like it?... go and whine to Roger, like many do... maybe he'll ban me!

Oh, my life would be crushed... what to do with all my time in a place as boring as Sun Diego... if I only had some toys...

Some of you are really amusing!

Don't worry Ralf, just come back as Peter signit98 or Ole signit98. No-one will know you were even gone.

Some claim it does not make a difference, but the first time I got BP Ultimate 98 in my S, I pulled an accidental wheelie out of the gas station...

It's good high octane stuff.

...yep ; crazy stuff, this BP Ultimate...
...my favorite brew...

...in Germany I always fill 'her' up with Ultimate 100...
