Hi All,



Need a little assistance please. My new TW and went to Yamaha delaer for its first 1000km service 2 days ago.



I took it for it's first ride yesterday after service. when cold, sounds and works awesome. as soon as engine warms up, Loud "ticking sound" from engine and lack of power on 'topend'.

as it is still under warranty, i am having to take to tomorrow back to the dealer for them to look at it.

Just would like your feedback and thoughts so at least I walk into the garage with some knowledge. (PS: I am mechanically challenged




extra info: When i collected my bike from its first service, they told me they had to adjust the tappet settings as they "heard" some noise. I have driven 1000 km on it so far and have not heard any such 'noise'. Now after service, it sounds terrible.



thanks all in advance.

Listen to my engine in the "Buzzard Lagoon Road" video. When cold or when running above an idle it sounds pretty good, but when hot and idling it makes an awful ticking sound. I have adjusted the valves many times but it doesn't do any good. I have no idea what is causing the ticking sound.



A neighbor has a much newer and low mileage TW and we compared the sounds the two engines made. Mine seemed a little more pronounced than his but basically they sounded the same. I even had a stethoscope and listened to his and my engines. They seemed nearly identical. That is when I stopped worrying about it.



Could yours have made the noise before you took it in for service but now you are intentionally and intently listening for any strange noises so you hear every little noise it makes?



As long as it is warranty work take it back and see what they say. Mechanics make mistakes too. We all do.

I'm thinking either a.) improperly adjusted valves or b.) loose rocker arm locking nut. I'd suggest asking them to double check the valve clearance to ensure that it is within spec and, if the adjuster lock nut is loose, to check the thread on the rocker arm valve clearance adjusting screw to ensure that it isn't stripped or damaged, which could lead to the lock nut coming lose again in a few miles, even if they tighten it now.

I just bought a 2013 a week ago and I've noticed similar. But I was not so concerned because prior to really taking it out and riding it I read of something similar in the manual but maybe yours is making a different sound that what mine does from time to time. For ME I have similar scenarios colder engine no ping warmer engine and I throttle up to get some speed on open road and I hear an occasional ping/knock, I think to myself I hope thats not bad.

Although the manual states,

"Your Yamaha engine has been designed to use unleaded gasoline with a pump octane number [(R+M)/2] of 86 or higher, or a research octane number of 91 or higher. If knocking (or pinging) occurs, use a gasoline of a different brand or premium unleaded fuel."

It goes on to say more; on my manual that was page 4-6 under the section that says NOTICE in the manual I got with mine.

Furthermore I have read the whole ethanol controversy here on this forum and since all the pumps I have pulled up to say 10% ethanol I go for Premium in my tank trying to get the least amount of ethanol possible, based upon what I have read and used my better judgement it sounds that the bike would be happiest with low grade no ethanol fuel. So for me I chalked the pinging/knocking noise to fuel but I could be very wrong. Just as Tony mentioned warranty, I would keep a close eye on mine and if the condition worsens (which it has not) 247 miles on it now I would not hesitate to take it back.

I've also noticed that from day one of riding to a week later the engine seems to be a slight more responsive and has gotten a slight bit louder in the exhaust area (NOT massive just seems to be the engine breaking in.)

I hope nothings wrong and thats just normal engine harmony!

Hi allthanks for the input.

I took my bike in this morning and mac's have agreed that the noise is not normal. As the bike is under warranty, they have contacted Yamaha South Africa and have received go ahead to open her up. They will be contacting me with what they find.

sob sob - My bike is having to sleep away from home this weekend.

have a good weekend all.

Phat,

I'm interested in what you find. Seems mine did the same thing this morning. I'll check when I get home but hope its something easy to fix as mine isn't under warranty.

laughing at the ear plug picture above.

After a week, I got my TDub back. They did nothing and are convinced this sound is normal. (They did try another oil, but still noisy). Please bear with me, I am not a mechanic - but his explanation was that the noise is coming from the valve springs and that I should not worry.



but worry - I am! Here is a video link on my facebook page where you can clearly here the ticking sound.

Have a great Friday all.

TW's are 1920's engine technology. You're going to hear noises coming from the motor. Plain and simple. Get used to what you're hearing now, and when something goes bad you'll know it by the change. Keep your oil fresh, and keep things adjusted.





Ride on.

In my "Buzzards Lagoon Rd" video, around 4:15 to 4:30, is a good example of the kind of noise my TW makes. Yours sounds a lot better than mine.



I listened to your facebook video and it almost sounds like an exhaust leak. Check the bolts that hold the exhaust pipe on the head. They are just 7 ft lbs and that isn't very tight. Just snug them up if you don't have a torque wrench.



Honestly, to me, it sounds pretty good.



Good luck.

i just bought a tw brand new 2019 model and just hit 100 miles so i changed the oil and noticed the same noise right after i changed it, it's only once the bike is fully warm and at idle, if i give it a bit of throttle it goes away or settles down a bit but comes right back again, first i thought i messed up and put too heavy of oil in it which was 20 50 so i drained that out and put in 10 30 and it just seemed to make it even louder, so just wondering, i know this topic has been probably beat to death but i havn't been able to find a solid answer

Besides what RBM mentions, as lean as these bikes come from the factory and perhaps depending on the gas you are running (ethanol or non ethanol) they can be noisier than you like. Once you are done with any dealer warranty checks/services open up the pilot jet to 2 1/2 turns out or so and fine tune from there. Plenty of details about there here on the forum when you are ready. It could also do this if the idle is set too low.

20w50 is too heavy for all but 100 degree plus desert riding and 10w30 is too light. As the manual makes abundantly clear, 10w40 is the preferred weight for 95% of environmental conditions. Keep that in there for 1,500 miles (with changes) before going to 10w40 full synthetic like Mobil 1 Racing 4T. Make SURE what you buy is for wet clutches.....just spending a few extra dollars on Yamalube dino for break-in is cheap insurance!

Check your valve clearances at around 600 to 800 miles. Some from the factory are looser than others. Mine needed a little bit of tightening at just 600 miles.

My 99 has always been a little noisy but thats ok because it now has 43000 kms on it and it still sounds the same. When I first bought my 15 with 782 kms it sounded so nice but after riding it for a while I actually think its louder than my 99. Guy at work bought a new Indian at the cost of 6 new TWs and its a bangin clangin rattling POS. Dealer tells him its normal. Somehow that makes me ok with a little tickin .... so long as it keeps on tickin.
