I bought the 14mm dellorto SHA replica and absolutely hate it. It ran very rich out of the box. I bought a set of jets but they were all bigger than the stock jet (that was my bad I should have paid closer attention). So, I soldered and drilled the smallest jet. No matter what I did, I could not get the thing tuned across the entire RPM range. It was either lean in the high end or rich in the low end. I finally gave up and switched back to the stock carb which is still a little lean at WOT but much better than the dellorto knock off.
Spooky Tooth finally got the CNS carb in stock so, I ordered that thing immediately. I should have it by Tuesday or Wednesday. I'll post my results as soon as I get the new carb installed.
