Engine noise, normal?

[srx70024]

I just received my Apex GT and noticed is has a "clacking" noise when running. I haven't heard too many of these run, so this could be normal. Should I be concerned?

What an awesome sled. I can not wait for the snow now. Thanks Yamaha for such a fine piece of equipment.

Most likely it’s the clutch. The RX had the same type of noise. I wouldn’t’ worry about.

Fuel injectors can also make a klicking/semi clattering noise. I'll pay more attention as I have only had my apex running for about 3 minutes

My RTX makes the same chatter. It is comming from the clutch side of the sled. Haven't had to the time to investigate it yet. It probably isn't anything. When I really run her for the first time, we'll see if it clears up.

Most likely the reduction gears.

Most likely what you hear is the clutch. If you think the 4 cyl. is bad you should hear the 3 cyl. 120 vector clutch. My rage had a nasty rattle all the way up to 5500 rpm even after I installed the o ring kit it was still bad. The cluth noise in my attak is much better,only a little at idle but it goes away as soon as I rev it up.

Wife's new APEX GT is a quit as a mouse except for the exhaust purr.

Hmm, I don't hear much and have run mine at idle twice but all sleds I have ever owned make some sort of weird noise when starting out.

No worries yet Give it 20-50 miles.

Just remember, their is no exhaust pipes in the front of the sled to muffle the sounds coming from thinks like the clutch and the reduction gears. On my RX1 I spent the first miles listing to strange noises than turned up the MP3 player and never looked backed....

If you really want to hear noises, take a nice slow ride with no helmet on sometime. You won't believe the noises you hear.
