So who has used what?
First change out I went with Napa #250275, this time I went with Gates #275. As mentioned in my earlier post 'any suggestions?' it's running rough. I will be rechecking the timing mark positions to make sure I didn't miss it by a tooth. I did notice it was a tighter fit when installing the Gate belts and when compared to the old ones (Napa) they were a little smaller in circumference. I figured that was due to stretching. I will count the ribs tonight and compare and thinking that any difference in numbers there would be a progresive change in timming happening. Just thinking out loud here and may be over engineering my the solution to my problem.

Gates manufactures the NAPA belts. One question, were you having a problem both times you changed belts? Honda calls for replacement when needed after 100,000 miles inspection interval. I checked mine at 100k, buttoned it up and am still using it. Looked like new, also the idler and pullys were fine. Hoser
