[QUOTE="soulmate33, post: 979125, member: 56204"] Glad to hear that the porting is running well. It has been mentioned that a jetting reduction will probably be required after porting. I'm just really surprised that you can go as low as a 38 pilot. I'm running a 45 pilot at ~1.5 turns. This is at sea level here in Hawaii with humidity @ 65%-85%. Were you doing plug chops to get down to the 162 main? I'm running a 175 main. Did you try the stock 2000 CR250 (A715/289R/A327/A487)needle? Or do you find that the R1368NS needle runs alot better? I'm still contemplating doing a big bore or just a port job. [/QUOTE]
