Right behind the radiator. You need to remove the side fairings to get access.
unless you change the 'pizzaboy' bike manually you cant actually find the Yamaha 600r i don't think. i just read the vehicle changes he made for vice city deluxe and next to the yamaha 600r under the 'done' header it says NO. this is the only vehicle it says it for as well which would explain why it can't be found.
93 octane or higher.
2 quarts i think
0,8-0,9 mm
NGK recommend 0.7mm. For further assistance contact www.aprilia-merseyside.com
there is a clear eyeglass on the left side of the motor near the center close to the foot pegs. the oil level should be right in the center. you don't want to over fill it
KBB value is $5575
321cc +/- 5cc
3.07 Quarts with filter change.
Airbus A300-600R
Yes you can use regular unleaded fuel and it will not harm the engine. Although by using low grade fuel, you will not get the max performance from your bike. I have a 2002 YZF 600R and use nothing but premium in it now. I use to use regular unleaded and I found that I would change my plugs at least once a riding season. it builds up alot of carbon. But yes the owners manual says that you can use regular unleaded.
I just bought a 95 xr600r for 2000$. but this one was in perfect shape and I think the guy could have gotten more for this one. For your average used 95 600r I would think about $1500-2000 or so.
