[QUOTE="canyncarvr, post: 294015, member: 16552"] [b]stuff...[/b] dd: You know what you're doing. You'll get the two bike differences figured out I'm sure. jetting in general: Keep in mind that the idea of requiring smaller jets ('leaning' the mixture) with the addition of pipe, airbox mods and such is [b]WRONG[/b]. The stock jetting is [b]SO[/b] off, that when you improve flow of the system (like airbox restriction removal through snorkel removal, lid drilling or complete lid removal), you end up (for example) with a smaller jet than stock...[b] but richer than it would have been in the first place had it been correct[/b]. The amount of fuel mixed by a carb is not a matter of the AMOUNT of air going thru the carb. Instead, it's a matter of pressure differential. That's what venturis do. The decreased air pressure in the carb causes atmospheric pressure (as 'felt' by the fluid in the fuel bowl) to PUSH fuel into the airstream. The bottom line is going to be what's correct for your situation. Taking gilsbike for example, a 170 may be correct depending on the type of riding and elevation. DOES sound a bit iffy to me (I wonder how a 170 selection was arrived at), but I know that I wish I would have HAD a 170 last time I was at the dunes (sea level). 160 is the biggest I had...and it was a bit TOO close to suit me. That's why reduction in airbox restriction generally calls for a RICHER jet....pressure differential is reduced; LESS fuel is 'pushed' into the airstream, a LARGER jet corrects that problem. o&s: Isn't a sharp jetted bike a delight??!! Yesterday (played hookie..call it a vernal celebration!) my '00 200 (38/152/BEL-2/#6TV) was perfect! To you folks that haven't done it...get your jetting sorted out. Yeah, it takes time and is a bit of a hassle changing this'n-that time after time. But you'll get to the point that you'll KNOW what works and when to change it..and your bike will be running better than you ever thought possible! AND...the RB post is an excellent read. JD lends terrific insight into L1, taperº, the magic number (how many of you even know what the 'magic number' is and why it's so important in needle selection?). I'll bet'cha there were about zero kdx'ers using a Cxx needle six months ago. p.s. If I'm surprised at how small a change to my AS (1/16 turn) DOES fix my problem, does that make me NOT lazy? :) [/QUOTE]
