How come everybody has a clean motor that post on here? My engine is filthy and without taking it out how do I clean it up? I've got some gunk engine cleaner (heavy duty) but am afraid to use it. Will it eat up the coating on the motor?

I'm old school.  A clean engine means you 1) care about the bike, and 2) makes any issue easier to spot since a weeping seal or premature wear is easier to notice.

I wouldn't use solvent-based cleaners unless you want to strip off the paint.  I'd opt for Simple Green or S-100 with a thorough rinsing afterward (yes, our bikes are designed to get wet despite their reputation).  When you're drying the bike, note any leaking seal areas.  Squirt WD-40 into any pivot areas to chase out water.  tension chain, check oil level and tire pressures.  Park lovingly in garage or living room until next ride.

I gonna give that a try when (if) it gets above freezing. I found out simple green doesnot work well after it freezes.  Knock on wood my monster is the only thing I have that doesn't leak

Non chlorinated break cleaner from auto zone. Then soap and water and finish with rubbing alcohol and micro fiber.  She sparkles.

The simple green is no bueno for aluminum, I would stay away from it.

sparkly clean is out of question for me.  it's a work bike and flogged hard as it should be.

i try to clean it but some of the valve cover discoloration is impossible to get off.  I know I am not riding her if she does not leak.  I have accepted that fact.  Both the dm620 and Triumph S3 leak leak leak no matter what.

Bad engine paint, heat and dirt spray  boo On the air cooled engines, I think it's part of the game.

Never had any issue with it on the five bikes I have.  The trick is to rinse absolutely completely, feeling for any slickness with your hands.

S-100 works just as good at 4x the price though.  Both basically cut through light filmy grease.  YMMV.

Stopintime, my engine makes yours look like it's off a show bike. I'll try to get a picture next time.

I ride everyday in NYC so it gets very dirty and it's hard to clean it every now and then since I don't have my own garage or space to clean it in. That, plus, the engine was already dirty enough from the last owner that I can't do much about it anymore Undecided

I just deal with it by not caring too much and riding it  Dolph

S100, a little scrubbing, and plenty of rinse water.

Diesel fuel to remove oil and grease, then plain old soap and water to finish.
