How do I service a yamaha 450 racing quad?

For future reference, always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer. Sometimes the year can make a difference.

Don't forget to lube and adjust the chain. Grease the A-arms (they have grease fittings for a grease gun). Adjust the valves.

Change the oil & filter. Check the brake fluid level. Check the coolant level.

Tighten all nuts and bolts. Purchase a service manual so you'll know what you're doing. http://www.motocom.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
