JD / blue clip 5 anyone ?

Recommended Posts

Hi everyone, just wondering if there is any other people using clip 5.  I see most people using clip 4, just trying to convince myself this is not unusual.

Current mods on my '02' DRZ400S are :

 

Stock piston, cylinder, bore, compression, carb.

 

Twin Air, JD jet kit, 3x3 (11 sq. in.). 

 

175 mj - blue 5 - 25 pj 2.75.

 

FMF Power Bomb, Power Core 4. 

 

Stage 1 Hot Cams. 

 

PS : I jetted richer than JD parameters because it was stuttering & stumbling at steady cruising speeds.

 

Thanks in advance for your replies.

Might be because your "3x3" is bigger than 3 inches x 3 inches.

 

Edit: Would also like to know the rest of your jetting. And what made you put it on clip 5?

You didn't mention what your other jetting is? That could be a factory here.

 

I wouldn't worry about it if that's what works for you. I'm really far away from the recommended jetting. And that's even with my air box looking like this (larger than 3x3 cut on top, plus more holes drilled on top):

I know someone will talk about the holes and running lean, but I'm finding my results are the opposite, I'm running a 150 MJ (one step richer for "safety", 148 made more power.), 38 PJ in my FCR.

Remove the airbox door, run it under the same mid throttle test conditions, if it feels better, drop the needle to clip 4..

Air/fuel readings is the best way to check you settings...You would find in summer clip 5 will be too rich..

 

The advantage of the mikuni carb is that it is reasonably tolerant to atmospheric conditions...usually takes some big variations to show more pronounced changes in performance

I did jet it in the summer, seems ok so I guess I'll run with it.

Did you try other settings or just went with current...?

The air box door test would be worthwhile..

Yes it went like this :

 

160 - blue 3 - 25pj 2 3/4.....Bike ran horrible, almost impossible to hold a steady throttle in any gear.

165 - blue 4 - 25pj 2 3/4.....A little better.

170 - blue 4 - 25pj 2 3/4.....Getting close.

170 - blue 5 - 25pj 2 3/4.....Really close.

175 - blue 5 - 25pj 2 3/4.....Couldn't be much better !

 

Thank-you & others for responding.
