I just installed the keihin 450r carb on my ds, WOW!!! What a difference! Everything went fairly easy, you have to modify your throttle cable a little, i also trimmed a little of metal off of the frame,where the fuel tank bolts down at, just to get the cable to line up a little better. Im running a 175 main jet, 50 pilot, needle on the 4th clip got me right on. Ive noticed a gain through the whole power band, alot more low end, revs quicker, all around out performs the stocker! A great hop up for $170. Special thanks to PredFan for the info!!![img]i/expressions/face-icon-small-happy.gif[/img]

Sparky, thanks for the props. You might want to try the HRC needle also, since it is a richer taper. This is the "Poor man's upgrade" as I call it. I knew it would work well on the DS. You gotta love the enhanced throttle response throughout the powerband! And top end is there too! Go to servicehonda.com part number is 16100-HP1-672.

hmmm 170 is great for a brand new carb... What kind of jets does this take? Does it adjust same as the stocker? (is it easy to open up/get at jets/needle?)
I wonder how this compares to a used tm45... HMMM
*just re-read your original post, I see this is the stocker on the 450r, which means they can probably be found used as well.* Ahh, I forgot you were in oregon, I am from dekalb, we still need to get together and ride sometime.

the stock carb and the Kehein off the 450r are the same size, and they both have a butterfly in the throat albeit for different reasons. This does make it questionable as to whether or not one can outflow the other for any significant peak hp increase, and only a dyno will ever be able to tell by fine tuning both same day same dyno on same bike.
But I do not doubt the low end response and better wheely popping ability thru to the midrange would likely be better, due to the accelerator pump. Pumpers rock. In my opinion a carb like this otta come on the DS's from factory.
