#90845 silver_fox (User) Senior Boarder Posts: 229 what do the Numbers mean?? 7 Months, 1 Week ago   Here's a real quick question. The numbers on the main, what is richer... 165? or 190? I have a 165 in and my pipes are black and sooty. 35mpg. Just so I know if I have to buy a jet kit or not. Thanks.   Logged       The administrator has disabled public write access. #90849 Big Bear (Moderator) All things in moderation!

You spend the majority of the time on the PMS and Needle. You need top look at those two IMO.   Logged       The administrator has disabled public write access.
