Easy Rider   Charley Posted on Tuesday, July 06, 2004 - 06:53 am:          Mikej Posted on Tuesday, July 06, 2004 - 10:31 am:        A straight \ imagelink { } worked. Image too small though. Looks fun to ride in any case.   Bud Posted on Tuesday, July 06, 2004 - 12:31 pm:        http://www.buellforum.nl/misc.php?file=2543 gr,b   Wyckedflesh Posted on Tuesday, July 06, 2004 - 12:44 pm:        118lbs of TORQUE! with 112 at 2500!!!! Holy HANG THE HELL ON TO THE BARS BATMAN!   Alex Posted on Tuesday, July 06, 2004 - 01:22 pm:        I canīt see 118ftlbs/112hp @ 2500. I see 118ftlbs @3850 and 102hp @5500. Obviously this engine runs out of air starting at around 4500rpm. Check Your heads and intake tract (especially the carb) on the flow bench. Still a nice toy Best regards   Spyder12s Posted on Tuesday, July 06, 2004 - 01:24 pm:        why cant I get in here ?   M1combat Posted on Tuesday, July 06, 2004 - 01:30 pm:        I think Mikel was saying 112Lbs/ft at 2500. I think his point was that this bike has a LOT of torque down low... You're right though, it does look like it runs out of air... I wonder if that's the classic 45 degree problem creeping in or not. I wonder what it would do with stage III Nallin heads... I also suspect that intake tract and filters. Doesn't seem to be enough volume in there if you ask me. Maybe the Dyno was done w/o them though? I still say it doesn't breath well enough though. I was expecting about 125HP out of this.   Charley Posted on Tuesday, July 06, 2004 - 03:43 pm:          Johncr250 Posted on Tuesday, July 06, 2004 - 04:25 pm:        Nice dyno graph! What are the engine specs again? (cams, compression)   Blake Posted on Tuesday, July 06, 2004 - 06:21 pm:        Wow, that is some serious down low power. Talk about effortless wheelies. Let us know how you do at the races.   420at145mph Posted on Tuesday, July 06, 2004 - 08:27 pm:        this is the black xb15 with the dual intakes?   Wyckedflesh Posted on Wednesday, July 07, 2004 - 01:39 am:        I seriously wonder how it would deal with a down draft dual throat webber carb for say a toyota or datsun 1600 engine...work up a semi highrise manifold and bolt it on that way...   Kaudette Posted on Wednesday, July 07, 2004 - 04:14 am:        Impressive but I don't like the crossover - not enough HP when the torque drops off the cliff... And I would expect when tuned that this engine should be more than capable of 125 hp... Hold onto those handlebars!   Easyrider Posted on Wednesday, July 07, 2004 - 10:57 am:        420at145mph, Yep it is....... MikeJ, thanks for posting the graph The problem is not the air (we will check Twice) but the fuell, it's emptying the carb.......   Easyrider Posted on Wednesday, July 07, 2004 - 11:02 am:        At This Dyno we still have a wheel slip of 15% on the dyno First we had 40% wheelslip, But when I was sitting on the back en pushing with my arms to the seeling very hard (still feel the pain) we still had 15% slip   M1combat Posted on Wednesday, July 07, 2004 - 11:04 am:        LOL . That would certainly cause it as well. Maybe try a five gallon bucket of fuel poured over the top of the engine as you hit 4000?   420at145mph Posted on Wednesday, July 07, 2004 - 01:45 pm:        so what all is in this bike? how much did it cost u to build? it started out as a 12 right? GOD DAMN I WANT 100RWP!!!!   Easyrider Posted on Thursday, July 08, 2004 - 03:11 am:        420at145mph, www.bikehospital.nl is the builder, you should ask him... about the cost.. Things There are in Heads are ported but ports are kept relative "small", slightly bigger valves. compression 10.8:1 Red shift 585 cams Honda 48mm CV carb of a VTR1000, a custom header with a twin inlet borla. We used Baisley valves , black daimond tulipstyle, multi angle. some related topics with Pictures http://www.badweatherbikers.com/buell/messages/32777/60871.html http://www.badweatherbikers.com/buell/messages/32777/42632.html#POST259668   Opto Posted on Thursday, July 08, 2004 - 03:30 am:        Very impressive! all I can say. That would be one wicked Buell.   Alex Posted on Thursday, July 08, 2004 - 03:54 am:        420at145mph, we normally get around 100 to 105rwhp with the following combination: XB12, stock cams, heads ported keeping stock valves, optimized throttle body , FAST intake system, open exhaust. Thatīs it. In some days I will know where a big bore XB9 will end. Best regards.   Wyckedflesh Posted on Thursday, July 08, 2004 - 04:22 am:        Easyrider, thats why I suggested the downdraft weber. If it flows enough fuel to feed a racing 1600 datsun or toyota it should feed enough fuel for this engine.   Easyrider Posted on Wednesday, July 20, 2005 - 04:19 am:        Wyckedflesh, thanks for the tip: http://www.oslracing.com/2005/Drachten/DSC_6978.JPG
