Alternator OEM Honda or Duralast

I have a 2001 Honda ST1100 and the bike is a beast. My alternator went out and I had to find a compatible model on ebay because they don't offer the OEM anymore.

Only use Honda oem denso alternator. Yes they are expensive but you will be replacing it again if you use an off brand. Been there, done that.

2004 Limited with 310000 miles alternator went out so went to local service shop . They were able to get it in and repaired next morning other shops in the area are a week backlog.Parts we're 310.00 (Duralast alt.and Gates belt)

I went with a Duralast Gold(90A) which never gave me a issue. If I had a oscilliscope im sure it had good output.

I have a 2013 manual. I've had to put 3 or 4 alternators in mine. The last one literally lasted a year, luckily it was still under warranty, and I only had to pay for the labor to have it changed out.

My 09 just ate its oem alternator also, at 225k miles, but its an EX without VCM. There was some oil in the area but I guess it can’t be from the spool valve listed in the TSB.

I burned up 4 of the duralast Gold GM 12si alternators while they were still under warranty, if I had to venture a guess it would be they don't like high RPM . I removed them from two of my samurai's and went back to stock, haven't had a problem since

I went through 3 duralast nators on my wife's exploder before I got one that lasted more than 6mos. Aftermarket everything has mostly gone to shit.

I have experience with both shitty Autozone Duralast alternators and I would not purchase them.

I have shadow codes for my water pump because of it, and my voltage is not high enough at idle, and never surpasses 13.5ish volts. It whines loudly, and it doesn't make the same power as my last alternator contrary to the ratings.

good luck ever finding an oem alternator that isn\u2019t $1700 from honda dealership. Denso been on back order for fucking years somehow
