Picked up my first vintage sled last month. A 1975 Snojet SST 440 fan. I was warned by a former Kawasaki dealer to lose my obsession for the "worst snowmobile ever built". But I couldn't stay away. On Sunday I found a 100% original 1978 Kawasaki 440 Intruder. This sled is surprisingly smooth and quick but bogs horribly under acceleration unless I feather the throttle. Let the games begin.

Welcome to the site!!

Check choke plungers for proper seating and check the carb needle holder o-ring.

Congratulations. The 78s are good sleds. Our 78 happens to be the snappiest sled of our herd and is always the first choice for my boys.

Thanks for the tip Vader440. Choke plungers make sense as it only starts to bog after it warms up. I hope it's that simple.

Double check the "O" ring on the main jet. If those "O" rings leak then the sled will behave similarly to what you describe.
Another condition that we have seen creating this reaction is blow-by on the piston rings.

I’ll give the carbs a once over during the summer. Thanks for the heads up.

Why was this guy a dealer if he thought it was the worst snowmobile ever. Tell him to check his facts, first year Kawasaki sold all their invaders made and in 1979 they made even more. Thirty to Forty years later they are still running strong and a cult following.

In 1978 I bought a Yamie powered new [non current] Kawasaki Sno Jet 440 SST. My riding buddy was not cheap like me and bought a new 1978 440 Intruder. Boy did I regret buying the SST. At the time we use to do lots of lake racing and his Intruder was at least 10mph faster than mine. He kept that Intruder for a couple of years and it always was a great sled for him.

where did you find the intruder at.?
