    I sound like a broken record...EFI haha.
    Come try these new fangled electronic carbys.
    I will start to think about an in tank pump arrangement to avoid (well for me atleast) that hideous frankenstein pump hanging off the side.

    Motorcycles are a hobby world. So don't be afraid to waste money. I recommend Mikuni TMR-MJN. Yoshimura's product lineup includes products for Katana. The setting parts are basically only the main jet. It is common with RS (TM). I think Keihin is inferior to Mikuni in terms of durability.

    Your attempt is novel and ambitious and I don't know anyone doing it in Japan. But I like steam locomotives better than electric bullet trains, and battleships better than missiles. I also like mammoths. Motorcycles are a hobby world. Your challenge is very interesting, but I like carburetors.

    Are they a better carbi than say the rs36 for street use, as I have never heard of them
    I will have to do some research on them. Thanks for the tip

    TMR is the successor to RS(TM). TMR-MJN are carburetors that Yoshimura has added its own improvements to TMR. Even the standard TMR outperforms the RS in terms of performance.

    Thankyou Takahiro,
    I have watched the Yoshi video of the TMR-MJN carbs and they certainly have created a different potential for the venerable carby.

    I have enjoyed the challenge of EFI as a hobby project.

    But seriously I adapted a VERY basic EFI system with my VERY limited resources and budget.
    But with all the information out there and the aftermarket possibilities not to mention peoples with more smarts than me surely the lure of EXACT an INFINATE fuelling/ignition for any engine specification (and not tipping a fancy watering can down the inlet port in effect I kid you not) would be more tantalizing add to that ECU's with multiple maps and integrated quick shifters, traction control, etc, etc.

    I have started to think about adapting a later model GSXR ECU so I can access these options including sequential injection just need a cam sensor (more than doable) amongst other things

    Plan plan plan.

    Anywho enough thread jacking and ranting.

    Cheers Andrew.

    Hi Andrew,
    I am impressed with you and your passion for Katana. If you and your Katana can attend the Katana meeting in Japan, you'll be in the spotlight. And it must be published in a Japanese motorcycle magazine. There are various modifications of motorcycles. Motorcycles are a hobby world.
    Takahiro
