Hello chaps

just a quick one:
I have a 2009 xt r with 750 miles on the clock,
I have only just recently noticed that when i start the bike up there is a rather loud vibration noise coming from somewhere in the engine (no idea where abouts).

It only happens when the bike is cold and being started for the first time,
e.g in the morning before work it will make the noise which will last approx 30 seconds. when i get to work and switch her off, i wait a few moments and try her again but she wont make the same noise.

Also it increases in loudness if i increase the throttle

Any ideas

thanks in advance

Andy

its not a sump guard?

im guessing no one else has this problem?

I've got a 2007 XTR and have noticed a similar noise like a buzzing sound.
It goes after about 20 or so seconds after starting from cold. This has only just started after the cold spell we have had. Not too worried and will see if it goes when the temperature rises

Some plastic bits can go a bit stiffer / brittle in this cold weather and transfer vibes that they might otherwise have dampened out � my Z was a little buzzy during the cold snap before Xmas, but now it's back in plus rather than minus temps all is well. Have to add that I was going a little brittle in the cold before Xmas too

Roll on the summer

yeah i have noticed that it was only happening during the cold, it had stopped for a long while now, since it had stopped snowing etc... however, i just rode over to france last week, where it was sooooooooo cold! (in falaise) and the noise had reappeared in the morning when i started it, now im back in england theres no problem!

strange though huh?!

Are you sure it isnt the fuel pump your hearing, its like a whirling noise like a washing machine!!??

If its more of a mechnical noise, im not sure. Ive an 06 XTR and never heard too much difference in noise when starting up even after it was out in sub zero temperatures for a while.

Sometimes (like 7 times of 10) in cold start mornings, I have similar resonanse sound. Lasts for about 20-30 sec.

Wouldnt be worried, these things make all kinds of strange sounds now and then - still they just keep on going

It is the oil pump I heard that it is normal, I didn't have that sound but I have read on another forum of it, then I changed my oil to Motul and now suddenly it is there. I think it just needs to build up pressure then it go's away.
