What RPM does a stock DS650 pull? Thanks in advance!

 

Hey Topper, Good morning.
I don't quite know if I am reading your question right ?
But
I have my Dyno results here from my basically stock DS and are you asking what is the peak RPM where she pulls hard at ?
or
Where it starts to climb

I think its early and I can't read just yet ?

Where's my coffee ? Ahhhhh
OK
My bike is stock internally (Cam, piston, & compression) but she really starts hitting from about 4000rpm at (30 horse) till 7500rpm and peaks out at its max of 51 horse.
Is that what your looking for ?

 

Older DS's had a rev limiter at 7700 rpm, the newer ones I believe are limited 7900 rpm

 

I have an 06 ds and the stock rev was around 7500rpm. I put the big gun cdi on and it hits the rev limiter around 8500rpm. Thats according to the stock rpm gauge.

 

all the baja x's rev at 7900 ur tach is wrong......

 

Thanks for everyone's responce. I was looking for the rev limiter RPM. Sorry I wasn't to clear. It was early for me too. If they rev to 7900 RPM, why would a guy want it to rev higher? Wouldn't that be hard on the motor? Float the valves? [img]i/expressions/face-icon-small-confused.gif[/img]

 

They can handle 8 something if i remember right....when they get super high revs guys go to stiffer valve springs.

 

Ahhhh, got ya Topper.

I have the 04BajaX with the stock bumped up rev-limiter and I still opted to put the (BigGun/Procomm) CDI on it because the bike just felt like it had more power to give at the upper RPM range. Hitting that rev-limiter at 7500 sucked when you haven't even topped it out yet ! Now my Dyno run shows the the power starts to fade after 7500 and at 8000 diveing pretty steep but its still there !!!. I don't think there's much more power to be had at the upper end of the power band on a stock bike. My self I don't feel the 300.00 CDI's give you all that much more performance compaired to the 100.00 dollar units but I hear the Mallory CDI's are pretty impressive.
I think the CDI's help a little bit on advancing your spark through out the entire RPM range but keep your stock one with you as I had my aftermarket CDI fail on me during the first few runs. I got it replaced and She is solid as Oak now... knock on wood.

I'm gone ....

 

redlines at 8500 i do believe
