Here is a little more info that I found while looking for something else

Back then you said his 135 DJ main was the equivalent of a Keihin 145? That'd be way too big a Keihin main jet. I think we've discovered since that it's hard to cross ref the DJ to K main jets.

I say just buy bigger Keihin main jets from the aftermarket to begin with and possibly get a better quality controlled jet too boot.

 

The info we had then was the comparison charts that have been posted here in the past, like the one from Jets r us. I guess we know now that they're wrong.

I wish I had saved my money and not bought the DJ kit. I'll probably pull it out and go with the Keihin parts. I wonder if it's OK to drill this slide, instead of using the spring?

 

Zomby -
It's interesting that the comparison charts are based on orifice diameter, but that there's such a difference in flow between the Keihin and DJ.

The carbs are essentially the same if not identical, aren't they? Others have installed the 2206 DJ kit in the 2009+ carb and drilled the slider. Us KLR riders will also drill the slider without adding any kit. If you don't like it, fill with epoxy and re-drill a hole of original size.

 

Meaning drill the Kaw slide? Everyone does; haven't heard any complaints.

I went as far as rounding off the inlet port entrance so air could flow in faster to raise the slide.

 

From memory, the slide and diaphragm are different between my 07 and 09, so I wondered if there might be a difference in the holes.

 

Seems to be the same part number for 07 and 09 slides as far as I can see.

Anybody have a suggestion for a richer needle than the Dynojet for the stock carb?

I should probably just buy a TM36, but I already feel a little silly about how much $ I've sunk in this bike...

 

N1TC needle is popular

Is this one adjustable?
