Rev Limiter Noise

It is my belief that Yamaha gave us throttle stops and rev limiters for a reason. With that in mind, I partake of both on every single ride on the little bugger.

I had noticed before that the rev limiter made a really strange noise, kind of like a cross between a sick bird and a dying VW horn. Last night on the motard track I realized there is actually a bit of an RPM difference between the strange noise and actually bouncing off the rev limiter. It actually kind of works well as an audible shift indicator.

Anyone else have this noise?

I hit my rev limiter the other night for the first time but it was just the normal buh buh buh rev limiter sound.

Same here with the buh buh buh. On mine, no other sounds accompany hitting the limiter.

Apparently I am not trying hard enough as I haven't partaken of the rev limiter experience yet.

Usually by the time you are on the limiter the engine is making less power then 1000 rpm earlier
There's not much point in hitting it, I shift when I feel the power nosing over
On a track there is probably some merit to using the rev range rather than shifting twice however
I cant think of any reason how the rev limiter could make noise, what is probably happening is the intake and exhaust note go off as the engine is not tuned to make power in that RPM range

See, you need to bring the little bugger to the track instead of that big brute! (you maybe under sprung and underdamped in the rear though since I'm about maxed out on the rear damping)

On a bigger bike you can actually feel the power curve drop off, but with little better and it is splitting hairs. On the big bikes I sometimes see the rev limiter on the track (depending upon which engine). On the little bike I frequently see it on acceleration lanes on the road and all over the track. Maybe once I've got a few thousand more on the little thing I will have the discerning feel, but until then I'll keep ringing it's neck. Also worth adding I suppose is that on the track my MX boots keep getting caught between the shifter and the the pavement which substantially delays the upshift.

I never thought of intake/exhaust note though for the sound. I immediately thought it sounded like an electronic oscillation, kind of like an amplified sound of the natural rev limiter.


Interesting feedback so far. 3/5 people hit there rev limiter. 1/5 have the 'shift indicator' sound.

But the big brute was just soooo much fun. There is nothing like lofting 3rd gear wheelies the length of the back straight before putting it down in time to slide it into the next turn.
