Danke. Ich war also ein teenager wenn ich habe Deutsch gelernt

zwischen kurbelwelle und getriebenleistung...

du bist richtig!

125° vot / 65 not ist wunderbar! kein problem über das Pleuauge zu fräsen (T5 welle) Uploaded with ImageShack.us

you're right: the new red curve with new jetting and PD. And you're right too: I need to fill the flat spot around 5000. I'm not sure if it's too rich or too lean.... Probably a bit too rich or just the begining of the reso??

I'm just back from the dyno. It's a rainy and moist day in Paris.. Uploaded with ImageShack.us</div> It seems to work fine now. I've lost a bit at bottom end but the gain is enough with an extra 1000 rpm. Pmax is at 7500 with more than 16 hp at the wheel..

you'll have probably more than 125 vot... your crank treatment plus your inlet opening backward make me think you're closer to 130° than 125°. Check it carefully...

danke!

who is dein "spritoptimierungstopic"?

here: Uploaded with ImageShack.us it's a very narrow place and I needed to be carefull not to bend the vaccum hose between rear absorber and frame.... But it seems OK.

too close to the star!

they sure rise their exhausts. A 1mm fudi on a standard cylinder gives around 173°....we're far from 192°!

a 1mm fudi gives you around 120-122° no more (it's what I have on my o-T5). 130° needs a much thicker one... Play it again with: http://www.race-base.com/race-base/home.html

Uploaded with ImageShack.us I can't see the fault you're talking; Marco has written 120/192° on the last of the four curves.. You can't get 15hp with a 116/168 vespa barrel.... 130/192 is still a too high timing for a small capacity engine... Lot of power on high revs but a loosy torkey mule for sure at the bottom...

at least 2,8 mm....

wieviel einlasszeit hast du?

yes: no P4 avalable in Paris intra muros.... It's gonna be amazing!

160/BE3/125 works no doubt it has leaned out the low-middle RPM and let the idlejet do his job.... I'm running a 140/55 for idle and it's close to perfection....

I've received and set up the Basic star T5 and... My jetting needs a complete change... it's much too rich by now from idle to the first 1/3 of the throttle. Afterward it's all crasiness and the engine revs like a rocket. I've been testing on idle 110/50; 120/50; 130/50, 120/45 all too rich. 140/50 is a bit too lean. SO I need to find the good one between 2,66 and 2.8... 130/48 (2,7) is maybe the right one. Main is now 140/BE3/125 I will try 160/BE3 to follow the advice of krank-hank

steuerzeiten original zylinder moteur sur l'établi et calcul des diagrammes: il y a de la marge admission:140° échappement:150° transfert: 116° (comme le PX200) admission ist anlass, échappement ist auslass, transfert ist üs.... so you can try : AN:150° (75° max blowback) AU:165-170° US:121° use a 1mm fudi and dremel your exhaust 2,6 mm toward the top to get 165°...

at the bottom of the piston. 0,2 mm 5 mm under the lower piston ring and 0,13 mm at the bottom....

zwei Finger auf der Kupplung! Ja richtig!! it looks like a square seizure... Could be a lack of piston-cylinder clearance or lubrification lean out....

ask your rebore dealer to be definitively sure...

dyno was scheduled for a 4 stroke just before so you have to time it twice: peak power at 7600 rpm

yes you're right it's still a crappy old barrel. I usually don't like kits but I made it for a friend of mine really happy by now...
