Yes, I concur- always start with the plugs! (after the battery, of course). From here you follow the path- eventually you arrive at the Root Cause. In my case, I got lucky with help from a bit of the "Dark Art", (what with the compressed air, and such), but that is where to begin. May your Quest lead you not into the domain of 60 Degree Sensors and Ignition Pulse Generators, but into the realm of Fouled Plugs, Stuck Valves, and Mice in Your Tailpipe! Good Luck, and Good Morrow!

 

ok so brand of plugs should i get and where? the local shop here sucks they are such a rip off as most shops are so is there a website that is good?

 

i checked the plugs and they are bad so am going to change them and should i change anything else while i am there the bike ahs 23000 miles on it?

 

Go to your local schucks or napa... they should have the correct plugs at a reasonable price.

 

Personally, I would go with a good plug. The iginition systems on bikes are fairly poor performing as it is, so they need a good plug to get the most out of them. I'd stick with NGK's.

Also, I would stay far away from Champions.

 

My plugs are Iridium, not sure of yours? Honda OEM (mfg. by NGK I believe) is the ONLY thing I would buy! My OEM plugs were @ $20 USD/ea. so as I said before, $80 later...
For my dollar:

- Look at me; goin' all Ben Franklin on your ***!

 

... yea Iridium plugs are pricey. I cringe when I have to replace the single one in my dirt bike...

 

Just sayin': if your using the Scientific Method to proof something, you change only 1 variable at a time, this is why I only use OEM parts as replacements. (except for Mods, of course, where the point is to "Improve" the original design!!)
