SheezFast02 Posted April 18, 2011 Report Share Posted April 18, 2011 I had a low-end bog after installing PWK 28's with 52 pilots and 155 mains, so I just switched to a 50 pilot. The Shee fired right up with the chokes and idled fine. I gave it a couple revs and it stalled, but won't fire back up. I'm guessing it's just flooded but I'd like your thoughts. I have the slides bottomed out because I was going to finally start syncing the carbs. So before I could do any adjusting with the idle knobs, she flooded out or something and now I'm stuck. I'll try starting it again later this evening to see if it was just flooded, but where would you guys go next if it won't fire again? By the way, here's some info: FMF Fattys PWK28's UNI Foam filter No lid 300' ASL 50 pilots 155 mains "NAPE" needle???

SheezFast02 Posted April 18, 2011 Author Report Share Posted April 18, 2011 Although nobody has chimed in yet, I'll go ahead and post my progress so far, as it may benefit another jetting newbie such as myself. After letting the machine sit for a couple of hours I decided it was time to go back outside and tinker so more. I went ahead and turned in the idle knobs a few turns to raise the slides just a little as a starting point. Along with the idle knobs, I also backed out the air screws another 1/2 turn (total 2.5 turns) from seated. Low and behold, one kick fired it up with the chokes up and after about 30 seconds I shut the chokes off and it idled on it's own. After warming it up, and throwing my new helmet on, I hit the shoulder of the road and went through a couple gears to see how she runs. The bog is still present, only not nearly as sluggish with the 50 pilots as it was with 52's. It's getting into the powerband after a slight hesitation. I'm sure a set of 48 pilots will get me pretty close to where I need to be and I presume I'll be able to dial the air screws back in a little closer to 1.75-2 turns. Does anyone have anything to say about my needle? It says "NAPE" on it. Never heard of it before. Would it be a good idea to switch to another needle or will this one be ok? I did a search and all I could find is that the KX85 uses this needle. Would appreciate some advice on what needle to use. Quote Link to comment Share on other sites More sharing options...
