It's better if you catch the parts instead of letting them fall out, and the O-ring might decide to stay in the carb, but yes, that's pretty much all there is to it. If it's a ZipTy, stretch the spring about 25% longer than it is, and if it came with a spring, washer and O-ring of its own, use that (keep the old stuff). Holding the screw pointing up, the order is, screw, spring, washer, O-ring.

There will be the matter of adjusting the fuel mix after installation, of course.

Anyone have any input on any particular ones to avoid?

I've heard rumors of the tips breaking off some and getting stuck in the carb, requiring replacement of the carb. :devil:

I got the MSR one I believe, and it fell out last weekend while i was riding, I had it adjusted about 2 1/2 turns out. I had read something about that problem before on another thread, guess it's true...I am waiting on a new one now, and amazingly, no one who sells them provides a spring and O ring with them, I guess they just assume you'll never need them. that makes absolutely no sense to me at all...

I purchased one from Anderson Automatics, it's anodized aluminum and screwed in OK but didn't have a real positive bottoming feel. I played with it until the bike ran good but I don't really know how many turns out it is???

I sent them a message asking them if they have had this problem reported before but never heard back from them???

I think I'd stick with the Dr.D. I have seen some made of stainless steel but would be concerned that they might damage the carb seat, then what do you do?
