I have three honda atvs. Bought a 220 Kaw bayou for my granddaughter.
At start up when it is cold you would swear that the rod is going to go out any second. After it is warmed up the knocking goes away. Any ideas?
Thanks,
Nick

Is the knock at idle or does it follow the full rpm of the motor?

It does not knock at idle. When you blip the throttle it will knock and then go away as the engine speeds up.

I would try adjusting valves and see if that makes a difference. Also check the cam and rockers for wear. What year is it?

I'm not trying to say that it's not knocking, but remember that a Honda engine is a lot quieter than a Yamaha. Most Yamaha's are just plain noisy.

Yeah, I was thinking Yamaha for some reason, but still not as quiet as a Honda.

Agree ^^^^^^ Yamaha needs to stick to sound equipment. Kawasaki???? well I dunno what they need to do??? lol JK all three have built some incredible machines in my day
For example the 1982 Yamaha YZ490 one of the badest bike of their time probably a good contender now?

AND Before most of you guys time.... the infamous 1975 Bultaco 360 a buddy of mine in Ga. had one of these things.

My brother had one of these NASTY fast! 82' KX250

I actually like the older stuff better moose.I have a yamaha mx 175 bike.It'll rip pretty good for a 79 on original rings and being a two stroke.

Amazing how a thread with an honest question needing some help from people that have experience on the topic can be turned into a free for all picture contest.
Sorry I asked the question.

Things go off topic, no big deal. Very possible that the oil is staying REALLY thick because of the cold, once it warms up it lubes everything like it should. Try an oil made for more extreme cold. Be sure you are using an ATV safe oil.
