I just bought a 04 ds650 with no tach, just wondering how many rpms this thing is supposed to turn ? It just seems to keep pulling ! WOW!! Mods are lectron 48mm, gutted pipe with hp research billet end cap, ported intake. Been reading this forum for a while, Lots of very helpful people in here. Thanks for your help! This is a very imppressive machine.

 

7500 stock

 

thought they were higher than that...even the low models...my baja is 7900

 

I think you are about right except the 2000 were alot lower. I think less than 6K but I could be wrong. I know you hit it quick. Reason we got a rev box for it.

 

Peak power with stock cams and carb is about 6300 rpm. Until you upgrade your cams, I can't see any benefit to revving past 7000 rpm. [img]i/expressions/face-icon-small-smile.gif[/img].............especially with the torque and low rpm hp the endcap makes.

Your carb should hold your torque curve out a little longer which will give you more reason to rev.........I just don't know how much.

 

Thanks for the replies, dont think I have had it that close yet, still getting use to the tourqe. I've been riding a 400 sport polaris and they are worlds apart. Any aftermarket places to get a tach for it. I think the wiring is already there for it. Thanks again for replies .

 

The new 650 stock will make the most torque between 55k-6k.

 

I have no airbox with the intake tube attached and some of oldmanracings carb mods. I also have a yoshi pipe and filter and i find the fastest way for me to drag race is shifting between 6800 and 7000rpms.

 

I talked to RWR before gettin my CDI and they told me the Rotax redline was 8500 rpms, but the stock cut out was at lke 7400/7500 until 2002 when they upped it for the Baja to 7900rpms, im not sure if they changed it since then, the Baja tach's read up to 10,000rpms, they r expensive, im glad the Baja model came with the tachs! comes in handy for some drag racin [img]i/expressions/face-icon-small-happy.gif[/img]

 

dirt wheels did a test on the bomb ds650 and there is some guy, i cant place his name that specializes on bombardier (factory mechanic) i think, and he makes his own rev boxes for those things that has no cut off point on them at all so they must be able to hold some serious rpm's.
