question about YZ needle


I have a 2000 DRZ (but I am not anti-yama). I feel like everyone had the same kindof money to spend and got the bike they wanted. My question is this: I recently purchased the needle from the 426 carb to install on my DRZ. I know that the YZ's have tendencies of fouling plugs. You dont suppose that the needle (allowing more gas to pass) would have anything to do with the plug fouling? I have had my DRZ for over a year but havnt fouled a plug yet. I'd love to gain in responce but dont wanna sacrifice it with added maintenance.

Thank you

You will not have been the first rider to try a YZ needle in a DRZ. It is a very good change for the DRZ also. If the needle code is OBEJP or OBEKP, start in clip #3(leaner) rather than the middle clip. The pilot jet at about a #45 (2 turns) or #48 (1 turn) and main jet should also be in the range of #158-162.

Thanks a ton. I did get the obekp. My bike is jetted at main 170 already.....I live as far south in Alabama as possible (Sea Level). A 160 was too lean. I will put the clip on 3 as you stated. Thanks for your help.

Ok, I am gonna try this mod anyway. The worse thing that could happen is having to go back stock if the plug fouling starts.
