Hey guys, I just added a Powercore 4 slip on to my 04' 150f. Now before I did anything a cranked it up to see what would happen, there was a couple of things I noticed after it warmed up.

1st: I could feel a little bit of air coming from the pipe/header connector. I thought maybe I didn't have the clamp tight but I checked and it's as tight as I can get it. It wasn't very much at all, just a tad....Could this be a problem???

2nd: I didn't ride the bike because it was so late but when I revved the throttle real quick it sounded like it was going to shut off but didn't and when I slowly revved the throttle it would hesitate for a second then catch on. From some of the info. I've found, it seems like it's the slow jet. Does that sound right??

I have yet to re-jet the bike although I did check the MAIN tonight and it is stock so I know it needs to be done. I think I'm going to go with the power up kit but don't really care about the "power" I just want it to run right. Also, I'm about 350-600 feet above sea level. Would the 42 slow and 115 main still be good???
