Pretty sure the LTR is just a needle and shouldn't wear any different.
Yes LTR ship big pilots - I couldn't get them to work but many can. I run a 35 in my 300!
Vagaries of environment, production tolerances, pipe & fuel??

I raised the clip, and power was definitely increased, but it stuck the needle lower in the bore, so this concerns me. Is the LTR needle made out of softer metal than a Keihin?
Also, unless I'm mistaken, my kit came with a 48 pilot, and I think stock was a 40 or 42. The air screw tunes in just fine, so I know the 48 is working, but I think it's only because the needle is very snug at the top. I know you can go with a bigger pilot if you run a fatter needle because fuel leaks past the needle even when the slide is closed. I'm afraid my needle is too fat and causing wear.
Anybody's kit come with a 48 and anyone see wear?
