Reviving this thread, as I (oops) forgot to answer this question and because I wish to appeal to the wisdom of the group. CBR600 (and 600RR) bikes have 40mm throat diameter throttle bodies. Stock NH650 had, at biggest, 32. Will adding 8mm of throttle throat produce a noticeably "twitchy" throttle

Wow. Lots to think about. Does the CBR600 unit have to be modified at all for differences in air flow? On Fri, Jun 8, 2012 at 8:01 PM, Kurt Nolte wrote: > Oh, intend full compliance with Rule #1: Always post pictures. > > With luck, there will be zero instances of Rule 34 in this project. ;) > >

I'm going the standalone route personally. The computer module + Harness is ~$350 (Microsquirt ECU pre-assembled), and I'm using the fuel injectors, throttle body, and TPS off a CBR600. I need a temp sensor (you can modify the settings in the module to accept a cylinder head temp sensor instead of

Standalone EFI doesn't take that much more sensors than the CDI already needs, and if you go with something like microsquirt for power you can also get it to do ignition and do away with the CDI. I'm a bit biased, but I love EFI and don't care for carburetors and their compromises at all. Besides,

I wouldn't say "much better" as most of the 600cc+ bikes are doing good to be in the forties. I am, however, working to put efi into an '84 650. Kurt On Jun 8, 2012 5:21 PM, "GPro" wrote: > Is there an aftermarket EFI system for the 1991+ CB750, or has anyone > retrofitted a system for another

Is there an aftermarket EFI system for the 1991+ CB750, or has anyone retrofitted a system for another motorcycle onto a 1991+ CB750? Newer bikes with larger displacement are getting much better mileage than the 750. -- You received this message because you are subscribed to the Google Groups
