Nice to see you went with the Yamaha 1100 instead of the Kawasaki 1100.
The Yamaha flywheels each have a different crank trigger plate length for the pick-up sensors on the 63M 1100 and 65U 1200 engines.
If you need to have your 63M flywheel lightened and trigger plate modified just let me know.
so im switching it back to a 144 pump with a new pitched (hooker) from dave at impros.....its gonna freakin scream now!!!!!
The pick-up coils and stator have the same resistance values but obviously the wires are shorter on the 1100-63M. Other than the 1200-65U pick-up coils having a black plastic housing they should bolt up and work fine if you shorten the wires. The ignition coils have a different turn ratio on the 1200-65U and the primary resistance value is a bit lower which would give a little hotter spark. The 1100-63M CDI has the timing at 19-degrees at 5,500 rpm for all cylinders according to the service manual and the 1200-65U CDI staggers the timing more 22-degrees front cylinder, 19 center and 17 rear to compensate for crank twisting. If you're running the triple engine in a lightweight hull you may just want to use the 1100-63M CDI or find a programmable box with a more of an adjustable timing curve with less staggered timing such as the Riva or Advent ignition boxes. Also the flywheel on the 1200-65U have a crank trigger plate pick-up that is half the size of the 1100-63M which might affect your timing curve if the CDI's are swapped.So will the 1200 stator pickups work with an 1100 front cover and flywheel,I know the charging coils should work or is something off that will not let this work?Basically what I did was mount the 1200 pickups and charging coils into the 1100 front cover. I know the 1200 has different timing curves for all three cylinders and the flywheels are different, just trying to get as much of this this sorted out as possible while the engine is still out of the ski.
what pitch is that?
