Has anybody done the extreme and bumped their 9 to a big bore 1200? Just curious. | ||

I think the NRHS folks have done this a number of times, and I seem to recall Aaron posting about it. The part that sticks in my mind is "third gear throttle only wheelies". Thats the sort of thing that sticks in a fella's mind, even if he's to chicken to do wheelies as a general rule anyway... | ||

I'm thinking about it for a winter project... | ||

Bud, what engine kit did you install? I'm thinking about having the 1050cc kit installed mainly because I don't want to have the cases bored. Should I go for the 1200? If so, Why? What kind of exhaust system are you using? Can I keep the Drummer? What about the ECM? Did you need a custom map? Lastly, what kind of power gains are you seeing. Sorry for all the questions and thanks in advance. | ||

macbuell -12oo bigbore -higher compressionratio ( 1:12,3) -very light porting -adj. pushrods -crackshaft •••. rebalanced -xb12 headers & a lucky race exhaust ( german ) i think you have no problems with re-using the drummer -stock ecm with pc3 ( sold my race kit ) cusom map ( every bike is different ) you could have my base map iff you like -19 hp + and 20 lbf-ft + ( 97 rwhp & 86 lbf-ft ) goal was a very forgiving and smooth powerband with more tq. in the low refs. mision acomplised this winter 48mm throttle body & injectors ( xb12 ) to go over 100 rwhp  crankcase vent. in a catch can so it stops lubricating the throttlebody and i'm looking for a better solution for the pc3 the stock ecm keep leaning out ( that's a feeling, still have to gather data ) i think that's due to the fact that is still use the bike for cummuting and it only just is at running temp. when i arive at work ps. 75oo km with it already gr, B | ||

HEY Bud If you are looking for an alternative for the PC3, go fiddle around at msefi.com a bit. Its a custom, you-build-it-yourself FI system, fully programable, in real time or through datalogging, it has so many options it is wild!! My brother and I just put it in his 84 VW Jetta, and it fired first time, idles way smoother, and has incredible throttle response. the best part is we allready have most of the components (if not all) on the bike in reguards to sensor and switches and TPS and such Just a thought http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=32777&post=313648#POST313648 Bruce (Message edited by rr_eater on September 08, 2004) | ||

Bud, what kind of pistons did You use to get 12,3:1 compression??? These must be high dome ones, arenīt they. Did You stick with the stock cams? If so, isnīt 12,3:1 a little bit high? Regards | ||

Alex, I was skeptic as well, but a friend did ride for 12ooo km with almost the same setup with out any problems And marcel ( bikehospital build the engine ) explained that that is was mechanical cr or static and with the overlap from the cams ( stock cams ) it was high but not to high ( correct me if Im wrong, I understand some part off the technology , but Im no way near a expert ) you have to ask him witch kind of pistons he used, I believe he did grid the heads down a bit.
