I know this discussion is a month old, however....changed out stock air filter with a K&N. Noticed fuel residue in housing area. Is this normal? Did rejet carb when after market pipes installed. Exhaust pipe manufacturer recommended main jet of 200. Still wondering if this could be causing this......before, it was 182.5 and remember it doing this too. Have noticed higher fuel consumption and would like to make it a bit more efficient for mpg. Any suggestions? Pipes are 2 1/2" Hard Krome Kickers.

You don't need to jet for pipes only and a K&N filter is the stock box, go back to stock jetting , remove the AIS, and tweak the pilot screw 1/8 to 1/4 turn out

Hello,
I saw this statement "K&N filter is the stock box, go back to stock jetting" in the quoted post above. I was under the impression that even though it is the stock box, with after market pipes (I have Cobra Slip-ons) you should re-jet to Stage 2. If this is not the case should I go back to stock jetting? I did a DJ Stage 2 re-jet last year with the 195 main..

My friend has an 05 silverado that was bone stock,he removed stock exhaust and installed cobra longshot type pipes with small/short baffles (pretty loud)along with also installing a K&N in stock airbox .

And just like Erbman stated his bike runs well with stock jetting & no carb adjustment so listem to Erb's advice.

I told my friend he would likely need to adj PMS slightly richer but he said since it seems to be running fine he doesnt want to bother drilling out anti tamper cap to get to PMS for adjment since its not acting like it's running lean.

But i bet its a tad lean with aftermarket perf pipes and better breating air filter, it's just not lean enough to degrade perf to the point he notices it.

Thanks Scott.. I'll give it a try.

The Barons kit suggested I step up to a 170 Mikuni from the stock 165. I'm running V&H longshots. I have opened up the stock airbox just a tad, and am running the K&N YA-1699, so I took them up on their advice.
I recently stepped back to the 167.5, and am still running the clip in the fourth groove on the Barons needle. I didn't notice any difference in performance. Still pulls strong, and has good top end.
I did have some lean surging with the 165, and somebodies needle???didn't know who's(it was there when I bought the bike from the PO), the factory air filter, and with the clip in the third on that needle.

Using the cross reference chart on the Tech Articles page, the 195 DJ, is something like a 183 or 184 mikuni. So yes, I think you could step back down, be fine, and not notice any change in performance. Might even run better. If you step down to a 180 DJ, you would be between the 167.5 and 170 mikuni, and could probably put the clip in the third groove(it may be there already) as well. The 176 DJ, would be the same as the mikuni 165. Since you have a DJ needle now, I'd stick with the DJ jets.

I think the carbs are set just on the lean side at the factory, and a little bit extra yields good performance gains.

I have the carb almost off atm, so I will probably switch to the DJ180. I have been frustrated by this since I switched from the Cobra Drag pipes that were on the bike when I bought it,(they were just pitted and it bothered me..lol) to stock headers and Cobra Slip ons. I can't seem to get the bachfire on decel to stop (lean condition) but I smell unburned fuel which tells me I'm running rich.. frustrating.. I noticed cracks on the coasting enricher cover and replaced that and just ordered a new diaphram/spring for the coasting enricher just to be sure. Hopefully when it's all back together my frustration will end..
I post my results

Thanks again.. ride on!!

Well.. the Stage 1&2 Dynojet kit that I have had 4 jets DJ160, 165, 190 & 195. I went with the 190 after trying the 165 at a few needle positions, took her for a short ride and I think I'm real close.. 3rd slot and PMS out 3 1/2.. tomorrow is another day..

Going off the comparison chart for DJ/mikuni jet sizes on the Tech Articles page, the DJ 160 and 165 are smaller then the factory 165mikuni. The 190 DJ is still a bit overkill. You can order the 180 from somewhere by itself if you think you want it. Might even be a shop around you somewhere that would have it.
Curt posted a link for Mikuni jets the other day that I saved, but I don't have a specific "I know they have it" link for DJ's. Google Dynajet, and see what happens. Hit the right one, and they might have a larger pilot jet also..........


The PMS out 3 1/2 is getting to the brink. If you wanted, you could get a hold of a 37.5, or 40 pilot jet, and probably reduce the 3 1/2 to somewhere closer to 2 1/2.
This would give you some more fuel on the decel when the throttle is closed, and your drawing fuel through the pilot circuit. In this article, he says you can change the pilot without affecting the mileage issue to much. The PMS will control the fuel flow.

Just my opinion, but for me, the 35 pilot that is stock, was on the lean side. This goes back to my opinion regarding the factory EPA pleasing settings.

Have you removed the AIS yet. If you mentioned it, I missed it.

Yes, I removed the AIS last year.. I am going to look for the Pilot Jets tonight, figure I may as well get both. One other thing that I did while I had the carb out was to take the enricher diaphram out and give that a good cleaning, I replaced the cover a few weeks back but didn't think to pull the diaphram out and check/clean it.

SKWEARpeg,
Tonight I was looking for pilot jets, then went back to read some of our Tech articles and came back to this post and it hit me.. when I changed the DJ195 to DJ190 I looked at the jet and needle that were on the bike when I got it a few years ago. Mikuni 170, the needle/jet were not stock like I had thought..(maybe Baron's??). So if this setup fails me I will go back to that.. I'm still going to pick up the Pilot Jets..

I think the 37.5, is a good small step.

The 180 DJ, and the 170 mikuni, are almost identical on the chart. With the clip in the fourth groove of the corresponding needle(DJ needle with DJ jet, and Mikuni jet with Baron's needle), you should be pretty good.
