[QUOTE="OldTimer, post: 1197543, member: 58798"] I recently posted to another thread in the pit bikes section about needle profiles, but I figure this would be a better place to increase the knowledge base about such a generalized subject, so here's the link: [url]http://www.dirtrider.net/forums3/showthread.php?t=135801[/url] If you don't want to go through the aforementioned post, my question is about Kehien needles. The carb in question is a PWK28 and comes stock with an NAPE needle. If you're rich on the needle, wouldn't you want to change the needle [B]jet[/B] rather than the needle in order to maintain the throttle curve characteristics? How are the needle jets sized? If you did want to change the throttle curve characteristics how would you determine which needle to use? In other words, what do the letters represent: 'N'-'A'-'P'-'E'? :think: Anyhow, there are a lot of other questions and info in the thread I linked to, so have a look and get back to me....K? [/QUOTE]
