My carb confusion came from a discussion about the xs360 carbs. Apparently parts are interchangeable between the 750 carbs and the 360 carbs. It sounded like the discussion was based more on the diaphragms themselves though. I've considered upgrading to a set of mikuni round slides as well, but my goal is to keep my build as factory Yamaha as possible.
Indexing the plugs is something I haven't been told to do in a long time, kudos! But that's something I've done on every aircooled bike I've owned.. so I suppose I should follow suit on this one.
My engine currently runs strong, but the threads feel too soft for their own good for the plugs. My initial plan was to pull the jugs off so I can helicoil those threads and clean all the gunk off my head.
I haven't been able to find much info on the cams to be honest. But there's enough people who want the dang things so I figured I should too. I also heard there's a significant weight difference between the 360 crank and 400 crank. Is the stroke of the rotating assembly any different from the two? And how is the interchangeability? My first bike was an rd250. When I sold it, the friend I sold it to slabbed some 350 parts on there and it became a stroker of sorts. Are there any similar scenarios with this engine?
I've also considered dropping the deck height on the head while it's off of there and having a 3 angle valve job performed at the same time. But that's money I really don't need to spend on a bike that'll always be "slow".
