Canary tweety sound

Got my KLR today. Love it, runs great but there is a funny bird like sound on acceleration. I seem to remember that I read something about this but struggle to find the thread. Is it a bad thing and what can I do about it? Cheers Lars

and my KLR silencer post:

A subjective topic but to recap recent discussions;

I don't like loud but I've replaced the stock silencers on both KLR's for several reasons, namely; lighter weight (5 - 7 lbs), better tone, better looks. .....I wouldn't recommend it thinking there will be a noticeable increase in power, nor would I put much faith in manufacturer's that claim much in the way of HP increases (with no other changes).

After much research and some testing, I like the LeoVince X3 which is relatively quiet at 94db, doesn't require repacking (the only one that doesn't AFAIK, except for the ridiculously expensive Staintune out of Austrailia), looks decent and has a spark arrestor and USFS compliance. Runner up would be the Lexx with the optional trail insert; also around 94db but it does require periodic repacking. I also like the FMF Q4 but it is a bit louder (though still trail compliant) at 96db (keep in mind that the increase in decibels isn't linear).

There are a great many aftermarket silencers on the market that are far too loud IMO and you'd do best to avoid them.

Good luck,

Dave

Thank you for the quick response. The bike has an aftermarket exhaust, a locally manufactured called Stealth. But stealth it is not, quite loud but ok. What causes the tweety sound and can it be fixed? Cheers

The typical "tweety" sound is caused by a loose baffle in the stock baffle style silencer. Since you have an aftermarket pipe, it may or may not be the same cause.....but probably not, especially if it's a packing type silencer. The only way to check would be to pull the silencer apart and look at it or replace it either temporarily or permanently.

Found the noise

I found the source of my noise. It comes from the tank. As soon as I hold the tank firm between my legs it stops. So off with it and find out where it vibrates. Put rubber insulators there and that should be that.

Thanks for all the help and suggestions.

The last person to have the fuel tank off may have dislodged one of the rubber mounting pucks off of the frame.

I have used strips of inner tubes to glue onto the existing center hump pads to put all or most of the weight of fuel & large tank bag onto the frame spine & center hump, instead of on the locator mounts.
