How do you make a Yamaha WR 450 F street legal?
Asked by Wiki User
have a "C" or "3" in the 8th diget of your serial number and your home free if not good luck.
It depends which state you live in because each state has its own laws. all require head light, tail light, brake light and mirror. Some states require 2 mirrors, turn signals and horn. Emissions is another big one. again, depends on which state you live in. California is notorious for near impossible emissions passing with "un" typical motorized vehicles on the street. Hope this helps.
What are all the steps to changing gears on a dirt bike?
Asked by Wiki User
You change the gears using your gear lever (obviously). On almost any bike out there you upshift by pushing the lever up and downshift by tapping it down, this also makes sense, doesn't it? Easy to remember...
The actual shifting goes like this:
Step1: Roll back on the throttle
Step2: Pull in the clutch
Step3: Shift
Step4: Release the clutch (gently)
Step5: Power up (also gently)
Some people might say things like : "You can get from 3rd to 4th without using clutch" or "you can downshift without using clutch" etc... Well, if you're not using clutch you risk damaging your gearbox which is quite expensive to repair. these features vary on different bikes so unless that person has a bike just like yours, don't do it!
What weight of oil does a 2005 Polaris Sportsman take?
Asked by Wiki User
Before choosing an oil, check this site out first. (excerpt and the site):
There are a few special problem areas for motorcycle oil. Most motorcycles have wet clutches, which means the motor oil runs through the clutch. If the motor oil has too much molybdenum in it, there are fears that the clutch can start slipping. No one I know has ever actually had this happen to them, but the warnings are all over your owners' manual and the oil companies' web pages. On the back of all certified oil cans is a circular stamp with the certification. Avoid oils that say "energy conserving" in the bottom half of the donut. These oils contain friction modifier additives that could cause clutch slipping over time. Essentially all 0w-20, 5w-30 and 10w-30 oils are energy conserving, and should not be used in your motorcycle. Most motorcycles run the engine oil through the transmission, and the transmission gears are very hard on the oil's VII package. This means that over a couple thousand miles, the oil's viscosity can break down. Standard car oils are only good for typically 1500 miles before they've lost about half of their viscosity. Remember, 10w-40 oils contain a lot of VIIs which tend to shear in your transmission, so I believe 10w-40 oils should be avoided. You can't use 10w-30 because of the friction modifiers. This doesn't leave much. Commercial 15w-40 oils are a good choice, because they have relatively few VIIs which are the more expensive shear-stable sort. Synthetics typically don't contain much of a VII package, so shear is not as big an issue with them. Some people use their motorcycles only sporadically. This means the oil can all drain completely into the sump, leaving no protective film on the bearings. The first start after a long period of non-use can be particularly hard on an engine. Film strength is very important if you're a sporadic rider. There are several key advantages to using Synthetic Oils: Synthetic oils have a higher viscosity index than mineral base oils. Synthetics have better resistance to thinning at high temperatures and thickening at low temperatures. Since synthetics have little or no VIIs, synthetics last longer in service without radical changes in viscosity. Synthetics have a much higher film strength than petroleum oils, so it takes a lot longer for the oil to drain completely off your bearings and into your sump. Diester synthetics are polar molecules with solvent properties which dissolve residues and combustion byproducts.

What do you have to do to make a 2007 YAMAHA WR 450 F CA street legal?
Asked by Wiki User
You need a good friend in Colorado. In order to make a WR450F street legal in Colorado you need to add a Baja Designs kit that includes turn signals, mirrors, speedometer, odometer, horn and DOT tires. In 2003 the emission law in California was changed such that no dirt bike can be converted to street legal. But you can buy a 49 state street legal vehicle and register it in California if it has more than 8000 miles before you bought it or you moved to California with you vehicle. BTW there is a new model WR250R 2008 which is California street legal.

How many pit stops are allowed in a motorbike race?
Asked by Wiki User
Racing motorbikes, with the exception of the Isle of Man TT are only allowed one pit stop and that is to change from wet tyres to slicks if the race is declared a wet race from the start - not including endurance races - if a race is declared to be dry at the start and it rains, the race is stopped until the weather clears up and it is then restarted, on slicks.

0w-40 full synthetic is factory spec, however many people use Maxima 10w-40 without trouble. Just be sure it is high grade, full synthetic, for whichever brand you choose.
