Hi, as most will know, im renovating my gsxr250, my question is, what do you think is the best course of action? 1. Strip it and start again. 2. change plugs, add oil and stand back. Its been sat for many years, the oil (by the looks of the observation window) has leaked out, the left side engine cover has been welded at some point all along the bottom. When I run my hand (latex gloved) around the lower circumference of the engine cover it gets oil on the glove. I have not removed the sump plug yet, as ive been busy with other areas. But the time is rapidly approaching to start work on getting to the frame for prep work. Any ideas would be great. cheers ade.
If mine, I would put some cheap fresh oil in it, a bit of diesel down each plug hole and give it a good spin on the starter(30seconds). When no more diesel comes out of plug holes screw in compression gauge and take readings. If the readings are within limits, fit plugs and carbs, give it some fuel and see if it will start and what it sounds like running. Japanese motors are quite tuff when it comes to sitting for a long while, and yours may be ok. If not, you will have to rebuild it. Find out first. The sidecover can be replaced or repaired without much trouble or having to strip the engine.
I would follow Murdo's recommendations, get what oil is left in the engine out. If you have a small strainer use it whilst draining the oil just to check that nothing other than oil comes out (peace of mind). Fresh oil, clean carbs and new plugs and fresh fuel of course should have you on track. Hook up a good battery and crank her over, hopefully you will hear the beautiful sound of Suzuki motor coming back to life, fingers crossed and good luck mate
Thanks gents. I will pop some diesel in the chambers and spin it a bit, then add more and let it sit a while whilst I check the fuel tank is ok. Then I will remove the sump plug and see what's what.
depending on what comes out of the sump, you might want to invest a bottle of Liquid Moly engine flush, put some clean oil and run it through with this stuff, then dump the oil and replace with fresh oil. http://www.liqui-moly.de/liquimoly/produktdb.nsf/id/en_1657.html?Opendocument&land=GB
I did pretty much exactly what the guys suggested here. But I used WD40 instead of Diesel. My compression was good on all 4, the bike blew out a lot of white smoke the first couple times I ran it but after it's first day at the track it was fine and been running well ever since. I don't know how long it sat unused but the tire build dates were 2003 and they were like new so it was a long while I imagine. Oh and I would recommend checking the valve clearances at some stage early on, one of my inlets had completely closed up.
