Question about 1991 BMW R 100 RS

1 Answer

Oil issue Usually my bike requires 3300ml for an oil change and around 3800ml when I do a filter and oil change. Since switching to this synthetic oil I have so far placed 5L of oil in and I keep getting an check oil light. I originally only put in the 3300ml and the level at first looked fine but after a 5 minute ride it was becoming slugish so I checked the level and added some oil. It was fine for 10 miles but then again was running low. I let it sit overnight to make sure the oil was cold and the level reading would be right. Once again it was low so I added more oil until it was just above the low marking, at this point it was up to 4600ml. This afternoon it did the same thing and showed low on oil. I finished off last of the 5th quart and now the level looks in the middle but it still is giving me a check oil light after about 3 minutes of riding. Another interesting thing I noticed is that the synthetic oil seems to be making a gel coating, white colored. I am starting to get really frustrated and cannot decide how to proceed. Please any advice would be very much appreciated.

It really sounds like you have water in the oil or some other contaminant (bike wasn't run on Castor oil?) You probably want to drain oil into a clean container and flush system before you do serious damage. Bike is geting hot enough to boil off water?

Is the oil for the Boulevard semi Synthetic or full Synthetic

Either oil will work, check your owners manual, it may say what came with it. If in doubt use full synthetic. You can't go wrong in doing that.

How often should synthetic oil be changed in a warm climate

If you are not using extended performance oil (which would include an extended performance filter) and you are not racing, it should be changed the same as non synthetic oil. That being said, different bikes require different oil change periods and a lot is determined by how it is ridden but I will tell you that synthetic oil outlasts regular oil by about 2-3 times especially in warmer climates. I use synthetic and I typically go by color, if the oil change interval is 5K miles then I check the sight glass and if it gets to be the color of strong coffee then it gets changed, typically it does not reach that point until about 7 to 9K miles on my bike.

I have a 2006 cbr 600rr, the bike starts and has a low idle and then the oil light and f1 light turns on and stays on and the bike goes into a high idle

you need to change your oil and filter.
a clogged oil filter will eventually bypass and let dirty oil through.
if clogged bad it will effect oil pressure by a pound or two and hence the oil light coming on.

if oil and filter are new, then check your code with the service department at the dealer or check your manual to determine what the code means.

Check that the oil pressure switch it working too. The wire may be loose, connecting to the switch itself. Thats usually noticed by a flickering oil light.

If all that is good then you have oil pump issues, oil flow issues, which should be unlikely due to the year.

I need to change the oil but i dont know what type to use

Any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate. 20w-50 for warm climate/touring. Do not use any oil that says Energy Conserving on the label . It will shorten the life of your wet clutch and transmission gears. Synthetic oils will help your bike run cooler and shift easier.

Oil capacity and regular or synthetic//

If changing your filter as well as the oil, your bike should take three quarts of oil as best as I know. Always check your oil using the dipstick when you change it. Change the oil and filter and add three quarts, start the engine and run it just a bit, two or three minutes. Check the oil level with the dipstick. The dipstick has two marks on it. The upper mark is 'FULL HOT" while the lower mark is 'FULL COLD'. Make sure your oil level is between the two marks and never overfill.

As for regular petroleum based oil or synthetic, you're 2001 machine came from the factory with H-D's Syn 3 20W50 synthetic oil in the engine, the primary, and the transmission. I'd recommend sticking with the synthetic oil but it must meet H-D's specification. Not all synthetics do. Matter of fact, very few do. Some that do is Amsoil, Royal Purple, and Mobil V-Twin.

Good Luck

Very hard shifting and clunking into gear

hi mate try not to use fully synthetic oil use semi synthetic and if its clutch slipping you will tell because when you put it in 1st gear it will jump forward or move a little bit but if not then your clutch is perfect also check chain tension if to tight will cause clunking good luck buddy :)

Neeed oil change information

I always use a fram filter from advance auto parts. As for oil, The older bike should not run synthetic oil. The clutches were not designed for it and can cause slipping. I use Valvoline 5w30. Should hold around 3 quarts. There should be a dipstick or site glass on the right side of the engine, almost behind the exhaust.

Changing the oil in a 2004 Honda CRF230F

The oil filler hole cap has an oil dipstick. Fill to mid range on the dipstick, about 2 quarts, just watch the dipstick. By the way, do not screw the dipstick in when checking oil level. Your bike does not have an oil filter. Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell.

Service details for a suzuki gsx1400 oilcooled engine

I think you mean a VS1400 or a VS1400GLP. I don't think there is a GSX1400. Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock.

First, check and , if needed, change the spark plug(s), and oil. Always use the stock spark plug for your particular bike. Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Change the oil filter if your bike has one. Changing the oil acts as the "filter" in bikes that don’t have an actual filter. Lubricate the chain. Lubricate the control cables with liquid graphite, ( Lock Eze ). Make sure the tires have adequate pressure. Check the spokes and snug up any that are lose. Aim the headlight and check all functions of the bike, kill switches, brakes, etc.

How about a top rating on this solution? Thanks!

Oil type choice

For the best results use a full synthetic oil - not a synthetic blend. When you change oil filters add an Engine Sentry to the filter.,,
