depends on motorcycle harleys have a few different places to change 1 motor oil 2 primary 3 transmission jap bikes usually have tranny inside crankcase and use same oil but make sure you use motorcycle oil with clutch and tranny additives gd luck
For the oil? On the oil tank you will see tubes coming off the bottom of the tank, there is two one to the motor and one will drop almost straight down. follow the tube and you will see the plug. most times it will sit right behind the tranny on the rh side of the bike. don't worry about the motor holds little oil and the tranny is separate and holds its own oil. If you need more help please let me know M.Woodring
There are two plugs on the bottom of the transmission, one for the engine oil, one for the tranny lube. The engine oil drain is the one that is closest to the left front corner of the oil pan. The other plug is the transmission.
The engine requires three quarts of oil, the tranny takes 20-24 ounces of oil.. Check the engine oil with the bike on the side stand. There are two marks on the dipstick. The upper mark is the "FULL HOT", the lower mark is the 'FULL COLD" mark. Keep the oil level between these two marks and do not overfill.
On the transmission, on the right side of the transmission, you'll see a chrome clutch release cover. It's behind the exhaust system. There is a plug that takes a 3/8" Allen or Hex key to remove. Check the oil level with the bike standing straight up.
As for what lubricants to use, I always use nothing but Harley-Davidson oil. 20W50 Syn 3 oil in the engine, transmission, and primary on 2000 and later model bikes. However, you can use other oils such as Amsoil, Royal Purple, Mobil, Motor Factory, and many others. Synthetic or petroleum based, your choice. Check the website of the manufacturer that you wish to use.
You can run Motor Oil in the Tranny or we run Automatic Transmission Oil in ours and we change it alot. We also run Lucas 2 Stroke Oil at 40:1. We run our Banshee and Yamaha Dirt Bikes on that also. Hope this helps.
I don't know about the Hyosung, but most motorcycles, motor oil is the tranny oil, same thing. To drain the tranny, you drain the engine. My bike has a dry clutch, so it doesn't have any gear oil. But my Harley was different, it had 90 weight in the gear box and also had a dripper on the chain that would drop motor oil on the chain every couple minutes. Most people never change the gear oil. Most cars go for life without changing it. If you had a shaft drive rear end, it would be full of gear oil, Check it out. Hope this helps.
Oil should be changed every 2 to3K miles. Anytime i buy a used bike i drain the oil right away cause u never know what might be in there...I recommend Castrol Syntec Actevo 10-40 wt. motorcyle oil..buy 4 qts...Put bike level on level ground and after you have drained oil and spun on a new filter...put in 2 qts...then check dipsticks (crisscroos marks on bottom of dipstick should be covered in oil when oil is full) slowly top off checking dipstick frequently so as not to overfill...proper dipstick check is to unscrew stick, wipe it off and reinsert without screwing it in, when oil is to top of crisscross you are full...My friends 2002 F4 has a sight glass NOT a dipstick so incase that's what you have watch oil level in sight glass (should be 1/2 to 3/4 full) Drainplug is under engine and is 17 mm...Good Luck to you friend....Tim
It's quite possible that when you fill the motor you are checking the oil level shortly thereafter, i.e. within 10 minutes, or you are filling the oil and checking what the level is BEFORE starting the motor (in this case the oil has not had chance to circulate and drain back in to the sump).
Once the bike stands for an extended period (a couple of hours or overnight) you will find that the oil has drained from the head of the motor, and other places, back into the sump and therefore shows at a higher level in the sight gauge.
motor and tranny filters and so on. I was looking through my manual on SMJ and on here regarding the amount of fluid to refill in the crank case and from what I have read I am coming up with 1.6 quarts according to the board. However when I follow the instructions for refilling I end up with about 875cc or approx 3/4 of a quarts in the frame spar/motor and about the same in the tranny. I am using Mobil 1 4T in the motor and Spetra Gold gear saver in the tranny (80W). Am I doing something wrong or is it supposed to be 1.6 quarts total in the bike (motor and tranny)?
When draining the fluids I drain all the ports and clean all the filter completely. The first time I filled the frame spar back up I filled it until it came up about halfway in the frame spar ran the bike for a minute and after it settled for about 5 mins filled it back to the half way mark in the sight glass. This totaled 875cc. The next day I saw the oil didnt appear in the site glass so I filled it again. Needless to say it started spitting oil out the vent tube on the way to work so I read up on it and found that I had probably over filled. The instructions I read though stated to fill the frame spar with 1 quart, start the bike and let it sit. When I went ahead and changed the oil again and refilled it I followed this method and again it was too full (over the top of the site glass). Can someone clarify for me the proceedure. The tranny is pretty straight forward but the motor seems to be a bit more complicated. As of right now I have the oil filled with about 875cc and when it starts up the oil comes up in the frame spar about half way into the site glass.
,Don't feel like your the only guy. Overfilling has happened to just about every owner in some way or another until they learn the trick to checking the oil.
I have never had less than 1 qt doing oil changes. It's always somewhere around 1.2 to 1.4 What I do is I lean the bike over to the left and then back to the right to help get most of the oil out. And I let it drip for a long while.
When I refill the engine I always add 1 full quart then start the engine for a few seconds and stop it. Then I top it off to the sight glass.
The rule of thumb being, never go by what the sight glass says if the bike has been sitting more than 10 minutes. Always check the oil right after you start the motor and shut the engine off. Reason being, the oil will drain out of the frame slowly over time so it makes the sight glass inaccurate the longer the bike sits. And every bike is different in how quickly the oil drains out of the frame.
