Schizo Posted February 16, 2004 Report Posted February 16, 2004 I finally got to ride my long anticipated Passion 12 port stroker. First of all I took my 13 front sprocket off and went back to stock 14/41 gearing. For break-in I mixed up some yamalube at 24/1. After a few hot and cold runs I started to get on it alittle more and actually hit the powerband and WOW it hits hard and pulls like hell, the problem was the flat spot before the powerband. After pulling the plugs and seeing how black and wet they were I then leaned out the needle 1 clip and the midrange got better, opened up the air screws till they were 3 full turns out and it got even better, went down 1 size to 48 on the pilots and it got even better, the problem is I still have a bit of a flat spot at the midrange. I dont know if its because of the CPI pipes, the rich gas/oil mix or the main jet. My next trip out I will be done with this rich break-in mix and then I will check the main jet if I can find a safe place to get this thing to 6th gear WOT BTW...this was all done in wet, loose sand. If the main jet is not a problem then I'm gonna try going back to the 13 front sprocket but a 13/41 seems geared a bit low for a motor with this output even if I do weigh 275 lbs. Quote

PassionRE Posted February 16, 2004 Report Posted February 16, 2004 Schizo, even at your weight that motor will pull a 15/41 no problem. Concentrate on the main jet and adjust midrange from there. When jetted correctly it will have an almost seamless powerband from around 3000 rpm clear through the terror zone...Jim Quote
fixitrod Posted February 16, 2004 Report Posted February 16, 2004 I don't have jims motor, but I did notice some of that when I got mine done until the rings were seated. It was like a light switch was flipped when they seated. Quote
Schizo Posted February 16, 2004 Author Report Posted February 16, 2004 I have pushed 5 gallons of break-in fuel through her so far and i'm gonna start looking at the main jet real close now if I can get her opened up, this bitch is faaast! Quote
Proquad101 Posted February 17, 2004 Report Posted February 17, 2004 Do you still have your airbox? I have the same motor and I cut the back half of my airbox off. My jetting is 172 main and 48 pilot and it pulls like crazy all the way from the bottom to the rev-limiter. Quote

Blue Duece Posted February 17, 2004 Report Posted February 17, 2004 I sure wish I could start mine up and drive it whats the problem rick?.......no spark? Quote
got1banshee Posted February 17, 2004 Report Posted February 17, 2004 I sure wish I could start mine up and drive it whats the problem rick?.......no spark? Thats it man, no spark. I have a stator on the way though so I should be up and running mid week. I hope. Quote
Schizo Posted February 17, 2004 Author Report Posted February 17, 2004 I do not have the airbox just the front part of it for the adapter. Jetting is at 180 and 48. Quote
got1banshee Posted February 17, 2004 Report Posted February 17, 2004 Yeah I ordered a stator from akpopeye off HQ and I have a feeling that I might have gotten stiffed on the deal. I paid him on friday and it is now monday night and I have yet to hear from him and I sent his several emails. So I am having a hell of a time here. I am about ready to just give up...... Quote

Rick you mean someone off the HQ stiffed you?......theres about a dozen guys on here id get shit from and he aint one of them.....did you pay him?...if not go to the dealer......how the fucck does your stator go from working to not over a motor change....that just dont sound right man...you shut your bike off, pulled the motor reinstalled it and now the stator is trash? i think the most minor thing is fuckin with you, i cant see your bike, but something is fishy with that, as far as this guy jacking you...lets hope he just had a long weekend........
