It really a question about comfortability. Some folks change their oil(s) every 5000 miles (or more), some every 2500/3000 miles and some might do it as often as every 1000 miles. Depending upon the model year of your bike current H-D specifications recommend changing the engine oil, transmission fluid, and primary chain case oils every 5000 miles whether using conventional or synthetic fluids.

That question is very tough to answer.
It depends on driving conditions and other factors. If the vehicle is driven 5,000 to 10,000 miles per year and not in dusty areas or in city traffic, you can change it at 5000 or 6000 miles.
If the vehicle is driven more than 10,000 miles per year, or in dusty conditions, or city traffic, the oil should be changed more often.
And using synthetic oil changes the formula.

Engine noise on left side


1. You can purchase a gear set that eliminates the cam chains and shoes. Harley-Davidson should, in my opinion, make this a standard fix and not an after the fact option. If you can't afford to install the gear system, then you need to disassemble and inspect the inner and outer shoes every 15,000 miles or risk total engine failure. The shoe material can also clog the oil pump totally destroying the engine. There are plenty of motorcycle magazines explaining how to fix this nagging problem.

2. Overheating: Harley-Davidson engines run hot. The 88 cubic inch engine ran hot and at the high limits and the 96 cubic inch engine runs hotter yet which is not good for the engine. The 110 cubic inch engines run exceedingly hotter and so much so a class-action law suit was filed against Harley-Davidson from riders being burned from the engine heat (mostly from the rear cylinder near the rider's thighs). Heat burns to the skin is not the only problem as heat is an engine killer and the hotter these big air-cooled V-twins run reliability falls drastically. Don't expect engine longevity with a 103 or 110 cubic inch air-cooled V-twin such as the Harley-Davidson design. Clean synthetic engine oil and a large external engine oil cooler is a must have accessory, but it only helps engine cooling not cure these serious excessive heat problems that self-destructs the engine.
Thanks

Using 1 quart a mth. no visible leakage. i can tell when it starts getting low by how it runs. live in mx. 110 /87% humidity. is this normal usage? i never had to put in extra oil and get it changed every...


One quart per month is a bit more than I'd expect but you didn't mention how many miles you drive during that month.If you live where the ambient temps are very warm, it may help to use a good synthetic. Synthetic oils do not burn off or break down chemically as fast as conventional oils do. I'd use a 20w40 grade.
Depending on the miles you've driven you shouldn't have excessive ring wear but the valve stem seals may have dried out and cracked. If the usage remains constant and there is no smoking etc, you could either leave it alone or have new seals installed.
Average driving is approximately 1,000 miles per month so when figuring consumption, use that as a baseline. One quart per 1,000 miles in very hot conditions is a bit high....I'd expect to see 1/2 qt or slightly less. One odd thing though is that generally, especially in an engine that holds six quarts to begin with, at five quarts, the engine should not feel any different!!!
Also.....you use miles to determine oil change intervals. Oil is best changed at between 3K and 4K miles. Only way you use the 3month method is if you don't use it much. (you can run most good synthetics longer than that)

How much fuel does a yamaha serow 225 WE consume per km?How long should i take to replace engine oil?what is the best engine oil type do you recommend i should use?What are the rite pressure units for both...


Your Serow should get around 70 Miles per gallon (28 kilometers per liter). I find that the oil in my bike is thrashed after 1000 miles of riding. It only takes one quart of oil to change it so that is probably the best interval for a single cylinder dirt bike. In you case every 1600 to 2000 kilometers. You should use only a JASO MA certified motorcycle oil. 10w-40 for cold climate/year round. 20w-50 for warm climate/touring. Car oils use different additives and may cause scoring in certain types of cam bearings. Do not use any oil that says " Energy Conserving " on the label . It will shorten the life of your wet clutch and transmission gears. If you choose Synthetic oils, they will help your bike run cooler and shift easier. Shell Rotella T and Rotella T Synthetic 15w-40 are inexpensive JASO MA oils. Trials bikes use tire pressures around 10 PSI (.7 kg/cm). Lower pressures are used for better traction off road. Street bike tires run higher pressures around 30 to 35 PSI (2.1 kg/cm to 2.4 kg/cm)for road driving. This gives better cornering and tire wear. For good all around performance for on/off riding you probably want to run 25 to 30 PSI (1.8 kg/cm to 2.4 kg/cm). For mostly street use 30 to 35 PSI (2.1 kg/cm to 2.4 kg/cm). There is probably a sticker on the frame near the side cover that tells you the factory recommended tire pressure for your model. Ride and make adjustments from there.

How often should I change the oil in my 2002 Nissan Frontier?


Some people change oil at 3000 miles,most people don't really care or keep track
I would say 3 times a year,if you drive less than 10,000 per year
4 times a year ,up to 20,000 miles per year driven
Use at least semi or full synthetic oil

What engine oil do you put in a 1997 twin turbo legacy gt


the best would be a fully synthetic that still remains relatively thick(comparitvely speaking for synthetics as theyre known for being thin oil) very runny,but get something thats 10w 40 or 10w 50 unles you live in the snow then thin synthetic is fine,unless the engine has done heaps of miles,even semi synthetic if youre on a budget,but minimum
