I've breezed though this whole thread and am at a dilemma. I want the easiest possible carb on my 650R (set it and forget it)...but all you TM40 fans are scaring me that an Edelbrock wouldn't run as good as the stocker!

I'm leaning towards a TM40, but what all is required to install it? I figure I'll need longer cables...but what about the boots to make it fit?

Fill me in on installation for both of them please.

Thanks

The edelbrock runs just as fine as the stocker. The stock carb does work great at WOT but if your not there all of the time, screw it.

I race my pig (finally getting decent at it too!) and if there is any drop in performance on the top I don't notice it. The pump does make a difference and I bet I can tune it to do more but by far the best thing ive found is the EASY starting. Drop it, just get up, kick (once), point bike and go.

The easiet way to go is to get the TM40-XR650R kit from Sudco.com. It comes with a new throttle, cables, and the carb. They say it comes pre-jetted but that hasn't been my experiance. However, there's enough jetting information in this thread to get you fixed up.

I had an Edelbrock Quicksilver carb on my 1996 KTM620 RXC (stock), with the KTM "Race" needle. I hated that thing. It was finicky and hard to start at random times. The carb was pretty, and was very well built, but it did not perform well at all. Most folks with RXC's of that era changed them out for different carbs.
In fact, I hated the whole bike (way too tall, heavy, and vibrated more than any bike I have ever owned)... and sold it quickly.

I don't think your talking about the same carb.

I called on this today and they said they are out of the carbs until the first of the year.

Any other suppliers out there? If I bought one used what do I need make sure it has with it?

My mistake. But, Edelbrock has more than one "Quicksilver" carb? The carb that is tuned with the needle only?....because that is what was on my RXC, and it was pretty much junk.

Party on, Garthe! ;) I have a 40mm FCR Keihin that I am planning to try when I get around to it. But I hear it may not fit beneath my tank and require some thermoforming?

E-Brock

I've had 3 RXC KTM's, 2, 620's and a 400. All had the E-Brock and I had the competition vent kit and accel pump added to all of them by Edelbrock. Maybe the new ones are different but I found with the single needle tuning concept, you could get it to run -reasonably- well in the low to midrange, or mid to top end but never both at the same time. The choke was kinda mickey mouse on them but they started "OK". All were replaced with Mik BST40's and the carb problems were solved. Again, maybe the newer E'Brocks are different and these problems have been addressed, I don't know. Unless I could ride a bike with a new E'brock on it and confirm it starts and runs to my liking, I'd certainly consider other options such as the TM of the FCR. Hope this helps.
