A freind of mine just bought a '99 KDX 200 (how dare you suggest I influenced him?). It is mostly stock with an FMF pipe and silencer.
I had some jets lying around from when I jetted my bike...
main- 152, 158 and 160
pilot- 48 and 42
I told him what I run and seems to work really well for me. main-155 and piolt- 45.
Obviously, those jets are in my bike so he can't use them, so he put in the 152 and 42. We have yet to chop test the bike and won't have that chance before we go riding next.
Here's where I get iffy. I thought my bike was acting just a touch rich (but I don't mind being just a little rich as it saves on the motor), so i felt confident that the jets he picked were o.k.. But now I went and checked on the FMF website and it recomends 155-160 main and 45-48 pilot.
I 'thought' that the 152 and 42 were recommended by some other site (can't remember which one though.. is there another site that has this calculation feature?)... But now FMF has me nervous.
Should I have him change out to the jets that are richer than mine until we can do a chop test? 158-48. Or do you think this is a good place to start and just keep an eye (ear) on it and take it easy if it seems lean?
