Dry starting engine

Wassup? I picked up an '80 KZ 750 LTD recently, & this bike has not been started for a year & a half or so................................. I'm in damp Seattle so I suspect the rings are at least a little seized to the cylinder walls, so to deal with that critical 1st turnover I'm thinking about spraying some WD-40 into the sparkplug holes to prevent scoring the cylinder by oxidized rings........................................

Anyone here have some thoughts on this? Thanks....................................

PBBlaster or Kroil would IMO be better for this purpose than WD40, because they are penetrating lubricants as opposed to WD40 which is more oriented toward water displacement.

Would spray several times daily to maintain wet coverage inside combustion chambers for a week before attempting to crank up the engine.

Sometimes bikes being stored inside a garage where a washer and dryer are being frequently used also tend to accumulate more moisture from the damp environment. Same for air compressor tanks.

Good Luck!

+1 on that. WD-40 is pretty useless as a lube, it turns to varnish as it oxidizes.

Gun nuts like me use Kroil for cleaning barrels because you can put it in the bore and let it soak and it will get under most junk and loosen it so you can remove it without abrasion to the bore. It does penetrate better than just about anything out there.

I just used a bic pen attached to a funnel to 10W-40 a teaspoon of lube in the cyls on my '78 Nova before firing 'er up.

Worked like a charm, too :laugh:

I think Wal-Mart even carries engine rebuilder's oil.

Try "Break Free CLP" Another firearms tool, very good penetrating lubricant.

I ended going with the PB Blaster 'cause that's all they had at the auto parts store, thanks for the input y'all..............................................
