Show me what you got!
Looking for a 62T stock exhaust or better. Upgrading a 1992 650SN to a 701 and building a frankenstein Kawasaki 300/701! Pictures of projects will be posted shortly.
Willing to trade or sell the 650 engine coming out of the SN.

not sure if a 62t stock exhaust will fit in a superjet. but i have a clean 62t exhaust out of a raider and a 61x exhaust out of a superjet id make a solid deal on.

62T came in the round nose SJ. If we can confirm it's the same exhaust for a raider vs SJ, let's talk! I'll do some research on my end. Thank you!

62t cases came in the round nose but still has the same 61x cylinder and exhaust but i think they changed it to the "64u"

the main difference between the 62t and 61x exhaust is the bolt size. 61x uses a m8x1.25 and the 62t is a m10x1.25. many people will just thread in heli coils to make the bolt size smaller so they can run the 61x exhaust on the 62t cylinder. friend of mine did it recently actually. the port heights are a little different but wont be noticable on a stock engine.

Thanks to Fastgtfairlane, SN will be good to go.

So here are some pictures of the Frankenstein 300 aka poor man's Rickter.
Engine mounts in, superjet 144mm pump with stainless impeller in. Blowsion tubbies glassed on. Thrust handle pole. Trim cable routed. Hull reinforced everywhere. Footholds glassed in. New turf is here, waiting to be put on.
About 2/3 done!

Still need:
trim nozzle
Coffman exhaust for the 701 going in to the 300 hull.
custom gas tank so it can be ridden more than 20 minutes.
