Couple of Simple FCR tuning questions

Recommended Posts

All this is for the newer FCR MX carb bought from TT

My bike – 2008 DRZ400SM

1. Is the extended fuel screw turns measure out AFTER you tighten it, so if it is 2.25 turns, that means tighten it, and then un-screw 2.25 turns?

2. Where does the EMN needle go, and how do I get there? I plan on taking the carb out. Pictures would be helpful.

3. Where is the timing screw? Pictures would be helpful.

This is probably too obvious to some, but I plan to taking the carb out soon, and having a good idea where things are will save me a lot of time and possibly some frustration

Will appreciate your valuable input.👍

Thanks!

1. Yes.

2. Needle goes into the slide. Usually from the top side of the carb but it's been so long I can't remember what you need to take off.

3. Flywheel timing bolt is on the left side of the motor on the top of the side case. 8mm allen I believe.

Very important!

Do NOT tighten the fuel screw. Simply turn it in until it "seats" then turn out (CCW) to where you want it to be. Tightening can damage the copper (?) seat inside the carb, making it useless

2.25 turns is recommended as a starting point... at the end of it all, With the bike warm and idleing you should...
