SlingshotmS

Thanks guys, you're awesome

Hi, I recently picked up a slabside 1100 with an 1127 engine and a unknown set of carbs. Plan is to use the 1127 engine in my 7/11 slingshot. The engine was running when i bought it, but due to clutch master cylinder problems I could not ride it, and i got it cheap so i figured i tackle any problems if some happen to appear.. Now to the question, what carbs are these??? When i google they look veeery similar to what appears to be carbs for the watercooled engines. In that case, fuck (and yay, good reason to invest in a pair of RS or FCR..) The opening towards the engine is 39,5mm on the inside by the way.

Just sent you a pm! Respond with your email if it doesnt work/if its blurry

Took the entire bike apart and will mount a 1127 engine tomorrow and start putting it all together, never bothered to install the M-unit when i had the 750 in it. But the wire diagram I posted will work for sure! The alternator in these old gixxers need "key on power" to function, so tbe orange wire should be connected to Aux 1 or Aux 2, and then you have to set the output (when you do the configurations for the M-unit) to "Key on power". Hope it helps!

Thank you for the input and the welcome! Sounds very reasonable about the main fuse location, but at the same time motogadget writes "Just make sure the main fuse is between the reg/reg (or alternator in our case) and the battery". Althou cutting the ignition will indeed kill the bike and thereby stop the alternator from overcharging so I guess that makes sense. Just wonder why motogadget says to put it between the reg/rec and battery... An introduction, of course! Michael 29yo from Stockholm, Swe. Currently have two bikes, one sv1000s with a usd fork and yoshi exhaust, and my project bike (mentioned above) that i'm just about to start working on. I'm going for endurance fairings w single headlight, solo seat, usd fork, swingarm swap and 5,5 rear wheel, m-unit, yoshi exhaust and a nice rk-paint scheme (have you seen michael viennes/championship cycles bike? thats pretty much the direction i'm heading). I'm still waiting for the cellar/soon to be mini garage in the apartment building to be cleared out before i can actually start working on it (probably 2-3 weeks) so at the moment i'm just spending money on parts, making plans and riding it as much as i can! Step two for the project (at least one year in the future) is to do an 1127 or b12 engine swap. But as for now the engine runs very good so it's not prio.

Hi, I'm about to install an m-unit to my gsxr 750 -88 and mocked up a wire diagram. Can someone tell me if it looks alright regarding the ignition and charging? In case the picture is to big to see I'll describe below. Two wires from alternator, one giving rectified current to battery+ via main fuse, the other recieving (key on) current from the ignition output on the m-unit into the alternator. One wire from (key on) Ignition on the m-unit, divides to 4 connections, one to each coil and one to the ignitor/cdi, and then also one to the alternator as mentioned above. One wire from battery+ (spliced, so essentially same wire that goes from alternator to battery+) to starter selenoid/relay, powering the starter if path is open (if i push start). Then one wire from that same connection point in the relay (the connection recieving power from battery+) to the "Bat"-terminal on the m-unit, giving the m-Unit power. Am I on the right path here? Or did i miss something regarding ignition, charging, starter and power to the m-unit?
