This may help, or this may further confuse the Dynojet vs. Mikuni issue, as well as the "less tapered" issue.
I rejetted a few weeks ago, and have had problems with reduced MPG. I wondered if I got the wrong jets. So I've been e-mailing the guy from MotorcycleCarbs. Here's the pertinent info for me--I run stock pipes (not drilled or debaffled) and a K&N in the football:
How many shims did you use on the needle? You should be using only the one additional we sent.
The jets should also be a 35/140 If you send the 150 back and it is not damaged in any way I can trade you evenly.
If it has bent ears from screwdriver torque you will need to purchase one of these.
Sorry for any problems this may have created.
We have just recently found out that the jetting specs we build from were
for using DynoJet Jets, but we were using Mikuni and the numbering systems are different.
So I'm going to order this new jet (its only $2.95) and just install that one. From the picture, its a lot less tapered, so that may be what MrBill is referring to.
I also asked about the shim--there was one on there already, so should we have installed the extra, or replaced the original with the one that came from the kit, etc.
