I found a post talking about the 954 being noisey.

Which 'Blade - 929 or 954?

Mine definitely isn't super quiet. It has a rattle that lasts 1-2 seconds on a cold start and then a duller rattle when it's hot. You might be able to hear it in this video.

MVI 0276 - YouTube

Unrelated to the noisy motor, but I checked my header pipe temps with a infrared thermometer and the second one from the left in the video is 60-80*F cooler than the rest. The others were all over 400F. I'm going to change the plugs on Thursday. Does Honda really recommend changing spark plugs every 5,000 miles?

 

yes these engines are nosiey between the cct and the htev its normal and noo do the pulgs every 16 or 20 k the first tune up is at 16 k i have 17k on my bike i did the plugs at 16 and checking the valves at 22 k or so i pulled the coolant system apart over the weekend and did a complete flush with fresh engine ice and made sure all the old green crap was flushed out

 

the big rattle on cold starts should be the HTEV.


moose, i don't want to worry you, but it sounds like you may have some sort of piston slap going on in your video (if your's is the second one)....

anyone else hear it?






and yes, the motors are loud

 

OK, I saw some old posts saying 8k for plugs and as low as 5k, but haven't looked in the service manual.

 

i heard a slight tapping but wasnt sure..

 

sup conrice nope i dident hear piston slap how many miles are on your 54 moostang

 

actually yep i heard it i just replayed 5 times and listened

 

hey conrice you know anybody that needs 54 parts?

 

that's my bike in the video. If the original owner was honest, then it only has 6k miles now.

 

hmm i have a 954 too it sounds like yours does the sound go away when it warms up?
