just bought a 2000 ds650 my first 4 stroke bike i have owned a couple 250r quads and a atc and this thing just feels dog'ish i cant imagine i should have to damn near jump on the back of it to bring the nose up seems to run fine i have checked the diaphragm at the top of the carb seems ok no holes the bike still has stock pipe but i saw it does have a procom cid and a k&n filter any thoughts

oh i did find the intake tube from carb to intake had a small crack but someone tried to repair it idk if it was leaking or not i ordered a new one

 

also has some popping in decel from higher revs, don't feel like it has the top end it should

 

Welcome

Congrats on the new buy.

 

Welcome to the Forum. I know what you feel like, I had a 250R ATC before i got my DS. A whole bunch of changes for sure. It will take a bit to get used to but you will love it for sure.
I found a couple of things to improve first were gearing, not sure what size of rear tires you are running - if you are using 22" you will want to drop the front sprocket by 1 tooth - down to a 15 tooth.
Exhaust - is it still stock? - if so you need a pipe to let her breath.
Carb - get it set up right, you should not have any poping or back firing. There are some carb mods on here, that do wonders.
A few simple steps will have you wondering how you lived without your DS so long.
