So Ive acquired myself the above, and Im wondering whats the best set up. I know there are other posts on here but I cant get a clear answer. Some sites such as Tbolt suggest the NAPE needle as the one that works best with 4 strokes. BUT, other mini sites suggest the JJH needle being the one for 4 strokes???? What gives? I'd like to know what needle that I am supposed to run on my Zonger 155, and what the difference between them are. Any reliable info would be greatly appreciated!

Which would be??? I have both the nape, and the jjh (which is installed now). My nape is bent a little though, and if thats the one to go with Id like to know so i can replace it. The nape looks slimmer, which the JJH is beefier. Also, Ive heard they have stiffer springs for 4 strokes. How can I get one? and why would i need one? Seems like it would be more arm pump to me. IDK, I havnt tried it yet.....

Because the nape needle i recieved is bent a little bit. I straightened it out as much as possible, but dont like fact that its not perfect, (yes Im a pefectionist). From what i understand, one is a little leaner than the other. You can bet i will be trying both, but id like to know which the carb guru's are running, because im not much of a carb guy.

I'm running the jjh with a 115 main and 42 or 45 pilot on my 177 +r and it's dead on. I ran a 110 main with my 150+r with the same results.I spent as many hrs. jetting as riding one year to get everything figured out for these pitbikes .Oh yeah I'm running 50/50 premium and 114 race fuel also.
