Hey mate, as usual posted and then searched! Seems this "chirping is quite a common - although not obligatory - side effect that nobody seems to quite understand

The "chirp" is not unique to our Rockets.
On V2Ks it is caused by the drive belt and rear sprocket.
I guess after 13 years riding these two monsters, I have become immune to the "chirp"! :roll: :D

Those wanting to quiet down their intakes after the air filter change might want to consider using MLV, or mass loaded vynal. It can be applied similarly as dynamat, using velcro.

It is commonly used in many applications including cars to quiet down road noise, so one can listen to the stereo without having to turn it up so loud.

It's available on Amazon and also from Sound Deadener Showdown | Your Vehicle Quiet You can read about it's applications there. It might be just the ticket to get rid of the crickets and tiny jack hammers some hear. :)

Hoopla
 
After seeing this post I tried the Dynomat thing too and it's the best £5 ive ever spent. Got rid of the crickets type noise and made the intake sound much more enjoyable. I'd starting wearing ear plugs all the time since I fitted the Ramair but now as the noise is much more appealing and I'll keep the earplugs for long distances only.
 
Mine doesn't make crickets...but it's certainly a symphony of noise.....I know it is the nature of the beast....so I am going to plaster some dynamat on the inside of the bearclaw as shown in a previous picture, to smooth it out a little.

Also, as I believe it was Rocket Scientist pointed out, don't forget to use a strip of 3/4' foam tape when you reinstall it to seal the gap between the claw and the tank. That also made a huge difference! Thanks Fred;)
 
What is dynamat

It's a super dense kind of rubber but also like tar with a sticky side. It's made for noise abatement mostly in vehicle door panels and such. You simply cut out the shape you need then peel off the backing paper and stick it on. Very effective! In fact I took my helmet apart and lined it with the stuff underneath the styrofoam and then reassembled it. I posted the pic's but I think everyone thought I was just nuts because I did it in a $750 dollar Schubert C3Pro.

Nice part of "Dynomat" is that it's only 3/16" thick and self adhesive. If you stuck 2 strips of velcro under it ( the hooks and loops )as in the MLV you'd be up to 3/8" minimum and there isn't enough room for that under the bear claw with RamAir filter.
