Yes, filter is in stock box. Replaced the white cover as preventive when I put it back together. The only thing I changed was the needle. I got a dynojet jet kit with the bike and I put the adjustable needle in it on 3rd groove. I will check for vacuum leak.
Just curious regarding the needle, is there something that made you do that? Wild hares are expected sometimes
I'm almost exactly like your setup, with the exception, that I went to the barons kit, and used the 170 main
, and the barons needle(4th), and slightly modified my airbox with an 1 3/8 inch additional hole.
The barons needle, was fatter then the adjustable needle that the PO
had installed in the carb
. Was the DJ
needle similar to the stock needle except for the extra grooves? If the DJ needle is slimmer, it may be letting more fuel past, but that would only be an issue from around a quarter throttle on up to WOT
. Using a DJ needle, in a stock 165 mikuni jet, may make trying to diagnose an issue on the www, more difficult.
If it was 40 before, and not now, I'd be looking for a vacuum leak, and or replacing the main jet with a comparable DJ jet to get you back on track. The comparable DJ main, should be a 176, according to the chart in the Tech Articles section.
You might also want to check where the enricher knob seats against the stop. Some people have had problems with it staying out just a bit, and have trimmed little thin donuts off the back of the knob one at a time, with a razor or exacto knife to make sure the enricher gets turned off completely.
