the tuning of this engine is alot diferent than my v-specs.they seem to like more fuel on bottom and leaner on top.
actually, mine were the opposite..you have to tune the lsn first, then the hsn on the GRP's...get the LSN to where the idle is steady (not dropping after a high speed run), and then adjust the idle screw for desired idle speed, then turn on the hsn...if you have the lsn too rich, you will get a lot of flameouts and fouled plugs - also, this engine runs much cooler then others...mine always came off the track around 190-205 or so
