What do you guys do to keep your carbs clean? I know this has topic has been beaten to death but my FZ, or rather the fuel, let me down today.

I went to ride the blue one this morning and it wouldn't start. Weak battery. Charged it up, then a few hours later went to start and it struggled. Finally got it running only to find a clogged pilot jet, lumpy idle and poor off-idle throttle response. The bike has only been sitting for 2 months, and I make sure start it once a week to let the fuel pump fill the bowls if any fuel evaporated and to warm up. She still rips up top, but the idle and lack of off-idle throttle response feels like a clogged pilot jet.

Same thing happened to my silver bike a few months ago. That bike never let me down, and even sitting six months one time with no battery tender it still started and ran fine. Then the last time I went to ride that, same symptoms, two cold headers from clogged pilot jets. Poor quality fuel, and unfortunately where I live there is no ethanol-free fuel available.

I know the answer is to ride them more so this doesn't happen but now with THREE bikes in the garage that's challenging sometimes. Will fuel stabilizer help at all?

Try PRI-G. Avialable on amazon and at rv stores. Absolutely the best.
 
Stabilizer it is then! Thanks for the tips. I thought I was crazy with this blue bike having issues after being parked for only two months, and that's with starting it nearly once a week!

Same thing happened to the silver bike but I just parked it. Yesterday I pulled the carbs and found two carbs with blocked pilot jets. Instead of cleaning I just replaced them with new spares from a rebuild kit that I had laying around. 2 hours start to finish and it's running better than ever!!!

Next up is the blue bike.
