Good day to you All,
Back in my mis-spent youth I had a shop install a Handle 4-2-1 exhaust on my Vmax. They said they could never get it running worth a hoot with a K&N filter (not pods, the one piece filter similar to the OEM design) so they stayed with the OEM air filter. It never did seem quite right after that but then and probably still now I didn't have anything to compare it against. Never took the bike back to them because I didn't want it broke off in my keister a second time.
A wild chain of events has happened since that install and now. Sadly I've just dealt with it. This spring it was running especially bad so I performed the Shotgun. Much better for about 100 miles then it started running even worse than before. I've finally overcame my reluctance to completely disassemble the rack of carbs and go through them with a fine toothed comb. I purchased K&L carb kits and air cut outs. Also purchased 4 new mixture screw kits because two of the four didn't have the tiny steel washers and o-rings when I took them out for the Shotgun. I am in the process of installing all of these items now. I've been reading a lot on this forum about jetting. Seems like 147 - 150 is where a lot of guys are running on the main. Mine is stamped .170 God only knows if the needle is stock but I can tell you the clip is on the 3rd slot from the "blunt" end.
It does run richer than Oprah for sure. I sure as the Devil didn't get this bike for fuel economy but on its best day 25mpg is tops and it drops into the mid to lower teens with judicious use of my right wrist. Like I said, to me this thing never did seem to run quite right after that exhaust install.
What mains would you recommend I start with? Are there other things I need to be aware of or consider during this R&R?
Thanks in advance,
Brad
