I bought this '02 R* during the later half of the riding season last summer. It ran decent but not great and had a terrible backfire on decel
along with it took forever to be able to run with out the enricher pulled out. First impression was it was terribly lean. Previous owner ranted and raved about the shop putting a stage one kit in the carb
and how everything was perfect. First thing I did was check PMS
and it was only out a 1/4 turn. I turned it out to 2 1/2 turns and most of the backfire is gone but it still takes forever to be able to run without the enricher.
I just pulled the carb and intake today and opened up the carb for inspection. What a mess. The needle diaphragm isn't installed properly and the cover didn't sit flat. The main
jet was loose along with various other parts.
I don't know what jet kit was used but guessing dyno
. It has a 35 pilot
, 195 main, and the clip is on the 4th groove (needle has 6 grooves) with one shim under the spacer. Have not checked float setting but it appears to be set quite high. Regardless of what brand is in it, I'm thinking of going back to Mikuni jets and needle. Would I be correct in getting a mikuni 37.5 pilot or 40 pilot along with a 170 main and stock needle.
My set up: K&N RC1980
Vance & Hines long shots, no baffles at present but plan on adding some
