so i know the savage is belt drive (i had one!)....has anyone used brake cleaner/contact cleaner (non-chlorinated) to clean an o-ring chain on a MC?.......if so did it cause any issues or good to go?

I recently sold my '03 Suzuki Bandit 1200. I put  33K on it. It had original chain and sprockets. I used a Loobman manual chain oiler ($35) using 10W30 motor oil. Gave it a 2ml shot every 40 miles or so. Never had to clean it. It dripped clean.

I installed the Loobman onto the Suzuki TU250 that replaced the Bandit.

once cleaned it was lubed with JP1 o-ring chain lube - cleaning it was a whole other story - 3 hours of spraying brushing wiping rinsing repeating repeating repeating.........it was so caked on with thick black gooey crud in every noon and cranny and the sprockets were gunked up the chain guard, the swing arm the inside cover over the front sprocket......just a freakin mess - new to me bike 03 model with 14k miles on it - looks like no one ever cleaned it just put some gunky crap lube that built up and collected anything and everything......hope to get at least 6K more out of it before i change the sprockets and chain and then keep it all clean and lubed.

Been using WD-40 on my KLR chain for 18,000 miles and still going strong.  I use the WD to clean it and then wipe it off.  As mentioned you don't want to use thin strong cleaners that will get under the orings.  Documented WD-40 only use and getting over 34,000 on a chain on this site-

I read the article and started almost from day one only using WD-40.  Besides being cheaper than chain lube ($14 a GALLON from HF and I put it in a spray bottle) the best thing is not having what OP said, lots of grime and gunk stuck on everything not just the chain.  I like having clean boots and pants without chain lube fling.  Just the cleaner aspect alone would have convinced me even if I got a little less life in my chain.  Been riding chain bikes with the gunk for 45 years, too bad it took so long for somebody to discover that WD-40 is all you need.

Clean well with WD. Wipe off all excess. Get Dupont Multi Purpose Teflon or Dupont Chain Lube, both pretty much the same stuff. Lube chain, remove excess. Chain stays clean. Every so often spray Dupont onto a rag, Wipe chain while spinning rear wheel. All done.
