Wow, what a beast of a bike :taz: Now I have seen a few reeded Kawi triples but I believe that be a pretty rare mod. Did you do that yourself? I can't imagine the amount of skilled work it takes to modify the cylinders for reeds.

I did a good portion of it. I do have machining experience and at that time, had access to a full machine shop I could use. so, it was def fun. I plan on reeding a set of t500 cyls, to get back on topic sort of. I have a spare set to hack into. should be fun

That would be pretty awesome and fun just to see you document the process here for us to see.

aaand finally! got the barrels and heads back. got it all bolted together, had to tweak a few adjustments.  petcock I had rebuild seeped a bit, so utilized a knockoff pingle I have and all good. replaced the points and verified timing etc. did a quick 5 mile ride, then a longer one after verifying everything I could. so, seems ok. def illustrates the differences between the modified 72 and this.

A lot of cooling fin area on that engine. Cylinder liner thickness looks overly generous too.
Built like a bank vault.

that motor was designed in the mid-late 60s. an air-cooled 500 twin 2 stroke production bike.. they had doubts it would cool.

even nuttier is the 8 head bolts.  the head design is just fkn dismal. total relic.  however, reliabe and functional

when you realize it was from THIS era, it makes a bit more sense.   https://petrolicious.com/blogs/articles/stealing-speed-how-suzuki-captured-cold-war-secrets-to-go-faster?srsltid=AfmBOor426-gFZHg0eso3WfB-cwIaOvxE_vvgc1uZpdcGAWVdcKP9wNS

so after swapping the jetting on the carbs to later style  (see here https://www.2strokeworld.net/forum/index.php?topic=5719.15 ).

i needed to adress the failing seat cover. it was original on a spare seat i had with really like new foam  . so, grabbed a cheap ebay cover and got it put on. surprisingly decent quality for 50 bucks.

so, the original bodywork was ok but wanted better. so ordered a set of professionally painted and restored bodywork in the blue green/white 71 colors. got it off ebay.  i like it, pretty happy overall but wasnt cheap. 1700ish shipped. came with petcock, emblems etc. only issue was they painted the sealing surface on the filler neck. so i carefully block sanded id down and installed it.

ill keep the original stored for now.
