1980 Suzuki FZ50 Project - Part 4 - Engine Removal and Partial Disassembly

[@jackrutherford-1]

that was one of the most informative 2 stroke engine videos I've seen. thanks

[@martincollins6071]

I love the fz50 lol I used to have one, if you coast down a big enough hill it will start itself lol I wish I could find another one

[@darkwaterblue]

Your on a roll :D

[@jackrutherford-1]

ok I never thought of using jack stands to support the body. thanks

[@BrainFogDanellesReviews]

How do I increase the fuel then to help it mix oil?

[@erlenddammen2174]

The stator cover does not originally have a gasket.

[@1marcelfilms]

i like the frogs

[@cosminraduta8267]

Have you given it more thought if you're going to flip it or ultimately keep it?

[@DrewsLair]

Got confused with the thumbnail and 1980 suzuki lol

[@TCGProductions03]

It probably cooked due to leaking oil from the oil tank seal

[@bbishoppcm]

Not likely. In an oil-injected engine, the oil is mixed with the fuel in the intake tube; if there's an inadequate amount of fuel (a lean condition), the oil will not properly disperse throughout the engine. Further, a lean burning engine runs hot; VERY hot. This excess heat causes the little oil that's there to incinerate, creating carbon deposits on the back-side of the piston, on the crankshaft, and inside the bearings.

@@bbishoppcm just found your set of videos while doing some research. My little brother informed me that he accidentally opened the oil cap and filled it with fuel. So I'm trying to find out what I need to do to help him drain it. He lives in Florida I live in New York. So whatever I find I need to be able to show him exactly what to do. He is not the most handy if it wasn't already obvious from his mistake. Any quick suggestions while I look into this matter? I'd greatly appreciate the feedback asap. Thanks!!!

[@bbishoppcm]

@@jeffutegg7321 Well, I'd suggest disconnecting the oil feed line from the oil injector and letting it drain into a bucket.

@@bbishoppcm how does it become lean? Dirty carb? I'm STILL trying to figure out my oil leak. I could bypass the oil pump but that don't solve why so much oil comming out exhaust header where it meets my head hole thingy. Heck, it even spits out the tail pipe. It's black. Ugh I need a dad rn lol

@@BrainFogDanellesReviews A lean running condition is caused by a mis-adjusted carburetor, a clogged/dirty jet in the carburetor, or a vacuum leak. In a two-stroke engine, any of these issues can become fatal and cause engine seizure. In your case, it sounds like your oil pump is DUMPING fuel into the carburetor and causing all sorts of problems. My recommendation to you is to actually REMOVE the oil pump and buy a block-off plate for it, then switch to premixed fuel; this will eliminate the often troublesome oil pump and give you more control over your fuel/oil mixture. This is a very common and generally recommended modification as these old pumps can fail, causing engine damage. Given the age of your engine, a complete teardown with new seals is basically mandatory at this point - and here's why: Once you've eliminated the oil pump, you still have the possibility of a lean condition as a result of a vacuum leak - on a two-stroke engine, the ENTIRE crankcase becomes part of the intake system, and a leaky crank seal (VERY common) or a failing seal between the crankcase halves can create a vacuum leak, which will throw your fuel/air mixture WAY out of whack
