standing up straight the oil should be between the marks.! you are welcome
To check the oil on bikes you normally have to run the engine for a few minutes, the turn it off and let it sit for a few more minutes, and check the oil with the bike standing straight up.
You check it while it is standing straight up and the correct level is 1/2 the site glass. A little over half would be ok but no more then 3/4 and you don't want to have less then 1/2. Hope This Helps.
Straight up
The oil level should be checked with the bike standing upright (not leaning on the jiffy stand) and at normal operating temperature. And to be perfectly accurate, both tires should be level with each other. However, once you've established the correct oil level using the above method, you can lean the bike over on the jiffy stand, let it cool off for an hour of so and then read the level again in that position. Whatever that reading is on the dipstick, use it as your reference to check the oil when the bike is cold and leaning on the jiffy stand.
There is a lot more to if a bike fits you or not than stand over height, but clearing the top tube with your crotch is an OK place to start.
you should have a race bike to jump high. to jump correctly you have to be in the attack position before you jump. the attack position is where you stand up on the bike, knees slightly bent, standing with your butt twards the back of the bike, elbows bent and looking always in front of you. never at the ground. when you are coming twards the jump give it a handful of gas ( still in the attack position until you land) when your in the air grip the bike with your knees to avoid wiping out. when you land make sure your standing and land with a bit of gas to even the bike out.
You should be able to find it on the left hand side. (Standing at the back of the bike) on the frame bare that comes down from the front of the bike.
Use the dipstick. The oil level should be between the upper and the lower lines on the dipstick when bike is standing upright on a level surface.
Standing, gives you more power.
Kick stand?
When sitting on the saddle the leg should no be straight, the knee should have a slight bend of about 10 degrees.
