The two Zip-Ty screws I have work fine. Just be sure to use the OEM spring instead of the one that comes with the screw.

I have the same bike with you. Merge has one of the best fuel screws i have ever used. You can adjust it even when wearing your riding gloves.

I've had a zipty in my 426 for about 6 years now....never any problems with backing out or anything like that. Stays put and does the job

I use the Pro-circuit fuel screw and it works just fine as well.

I have the moose racing screw made by zip ty and it is a great product, laser etched numbers anodized in many colors, and comes with a beefier than stock spring to prevent it from backing out. The spring really is stronger than stock unlike some that just say that. They run about $25.

Okay, I read up on a bunch of these, and the Merge one actually gets great reviews, and my local race guys actually use them (Blackfoot) and they also sell them for $30 Canadian, so I think I'll snag one. After fully seated, how many turns out should I start at? This will go with my new Jardine RT-5 full system...

Start at 1.5 turns out and go from there.
Not that it matters, but I have a Zip-Ty and no complaints.
