1968 Yamaha YL-1 Oil Question
This is what i'd do if it were mine Buy gasket set first, dont tackle anything until you have one (availability?) Drain the oil remove the clutch cover and magneto cover remove the engine from frame take off the barrels, heads and pistons / small ends for inspection, check for gummmed rings and also for ring wear, decoke piston crowns and note any oversize number and mark the pistons somehow L & R fill the crankcase with diesel for at least overnight to check the crank seals integrity (important) improve / replace and faults, carefully remove old / broken gaskets place piston pins in the freezer assuming alls well with everything drain diesel out place rags in the crankcase mouth (important in case you drop piston circlips) clean off old cyl base gasket, grease and fit new one oil small end bearings and bores refit pistons into bottom of barrels but leaving the gudgeon pin (wrist pin) accessible very carefully lower the complete assembly down and fit the pin and clip ...remove rag from case mouth when clip is safely home (use helper if needed) complete final assembly etc. grease paper gaskets before installing, they come off easier and can often be used again

Yamaha RS200 help needed
take the pipe off the carb and see if you have a good strong flow of fuel before you do anything else, there is usually a filter gauze in the fuel tap bowl...or there could be rust in the tap inlet tubes etc etc as merv says we appreciate an intro

1968 Yamaha YL-1 Oil Question
dan thats not quite how it works with a 2 stroke engine, there arent any passages as such, the oil is mixed with the fuel and lubricates the crank and bearings as this mixture is passed through the crankcase
