Transmission oil change
The V-star 1100, much like most Japanese motorcycles, uses engine oil to lubricate the transmission. (The engine and transmission share the same case and lubricant.) Therefore, checking the engine oil and trans oil are one and the same. There is a window that you look in when the bike is standing up straight.
The final drive (drive shaft at the rear wheel) takes Hypoid gear oil, and should be filled to the bottom of the threads on the fill plug.

I have a 1999 Yamaha 250 bear tracker that will not run at wide open throttle,idles fine ,when I give it the gas, it spits and spullters,can anyone help please?
Has the bike sat for a while? With gas in the bowls? Gas varnishing will cause a load of trouble. Also this is an old bike, when was last carb overhaul? If I had to venture a guess it sounds like a needle jet issue. Check air filter first and for any obstruction in the intake end to carb throat to be sure good clean air is getting in. Check the manifold (between back of carb and where it enter engine to be sure of no vacuum leaks. Spray some carb cleaner around the joints pipe or tubes leading to engine chamber, an increase in rpm is a sure vacuum leak. If all ok, clean carb throughout with brushing and cleaner not just a chem soak it will help a lot but not adaquatly clean jets and seats. Double check float level, even a mm off will effect some, finally knowing now all is good assuming you either used a carb rebuild kit after cleaning or at least replace any warn gaskets and o rings, go to needle jet measure for wear with specs and inspect for any dirt damage etc your issue sounds like either an over rich or over lean needle jet depending on the sputtering you describe is lean and running out of fuel at top end (floats and other jets also effects this) or is it bogging out too rich and if you back off it picks up speed then could be warn needle jet (also emulsion tube that the needle jet slides into). It’s a lot but really the only way. Best way to narrow it down is a plug chop and read the deposits on the plugs. The masters of this can dial in as good or better than a Dina-tune. I am not skilled at this but there are several internet posts about it. Good luck

Pressure washer engine replacement
The motor is unlikely to die. Yamaha are very well established in the field of building motors for all types of applications. They are renown for being reliable. If it did fail or you couldn't get parts, you could fit a Briggs and Stratton if you can fabricate the mounting. I doubt you would ever need to as long as you look after it, change the oil, use fresh fuel etc. Also they are low tech, not racing or high performance engines, they are built for plodding on and on.
