RPM to MPH in 5th Gear
Using a tape measure for the diameter of the rear tire:
1 Rev of the crank = [(Pi)*(Tire diameter in inches)]/[(Internal gear ratio)*(Transmission fifth gear ratio)*(Sprocket gear reduction)]
1 Rev = [(3.142)*(25.5”)]/[(3.083)*(0.821)*(3.200)] = 9.89 inches. 1,000 RPM = (9,890 inches/min) * (60 min/hr) * (1 foot/12 inches) * (1 mile/5,280 feet) = 9.365 mph
1,000 RPM = 09.4 mph
2,000 RPM = 18.7 mph
3,000 RPM = 28.1 mph
4,000 RPM = 37.5 mph
5,000 RPM = 46.8 mph
6,000 RPM = 56.2 mph
7,000 RPM = 65.6 mph
8,000 RPM = 74.9 mph
Engine Break-in specs and Starting emissions reduction
For the first 0 to 600 miles -- Avoid prolonged operation above 1/3 throttle. From 600 to 1,000 miles -- Avoid prolonged operation above 1/2 throttle. After 1,000 miles, change the engine oil and oil filter cartridge or element and the bike can be operated normally.
To avoid excessive exhaust emissions, never leave the Choke on longer than necessary. The time necessary depends on the ambient air temperature. Above 50* F use about 7 seconds of Full Choke. Below 50* F use 35 seconds of Full Choke and 2.5 minutes of ½ Choke. A warm Engine requires no Choke.
2008 Yamaha XT250 Maintenance, Intervals and Costs
A bike needs more preventative care than a car or truck. In particular, the XT’s maintenance schedule asks for both an oil change and valve adjustment at 600 miles, 4000 miles and every 3000 miles thereafter. Additionally, a host of minor items require checking and adjustment at each and every interval. A $205 charge takes care of these items every 3,000 miles at Motorcycle shops in the Chicago suburbs. You can expect tire replacements at 8,000 mile intervals costing roughly $182.50 for a pair. The Chain can be expected to last 10,000 miles -- replacements are $150+ (including labor).
For the home mechanic, oil and filter changes are easy. The element is behind a three Allen head attached plate easily accessible for both inspection and change. The engine oil drain bolt is located directly under the engine. The oil filter and O-Rings cost less than $5.00.
Minor maintenance is inconvenient -- both the supplied tool kit and the battery are accessible only after removing screws.
Idle RPM’s … Because it has a carburetor, the XT will not hold idle when cold without choke. After a minute of warm-up, idle runs as high as 2,500 RPM.
