need a little help on what oil I should use in my crank case. its a 1988 lt250r with vforce 3 reeds and a complete fmf exhaust. I had taken the entire bike apart and haven't touched the engine for a while. all help is appreciated.
I use ams oil 20w50 , it's there Harley oil, but it has no friction modifiers to hurt the clutch fibers, I use it in my gear box an had no troubles!
The suzuki 4 stroke factory oil works good. I used now ams oil 4 stroke atv synthetic 10w 40w in winter and 20w50w in summer
ATF type F works great just need to change it frequently.
Isn't ATF too light , thin.... No shock or cushion for the gears?
Ive tryed lots of dif oils but really like ATF
Lighter oil no drag! Maybe a Lil more hp to the ground, maybe like a one tenth?? How often do u change it?
I heard them changing after every ride. I run my ams oil for a month or two at a time. No problems.
Every few rides. If these things had sight glasses you could see it start to change color like purplish black and you know to change it. But lt's don't have a sight glass.
Use wet clutch oil with no addatives. You dont want anything affecting the friction of the clutch disks. You should change your oil frequently. Oil breaks down with heavy cluch use and collects a lot of particle cantamination from clutch wear. Frequent oil change also alows you fo see if coolant is leaking into the case and metal peices from broken components in the motor. I never go more then 10 or 12 hours riding between changes.
Another guy voting for type F ATF !!!! I know it sounds crazzzzzzzzzzy. But it is a beautiful thing! and it works! I change every 5-10 hrs. Its cheap, why not?
Type f too. Especially when it's cold
Valvoline Type F, O'riley's has it behind the counter.
Change it every 8-10 Hours
Hears what the guy at moble 1 said

Question:
Should ATF or Motor Oil be Used in a Harley-Davidson Primary
I understand that there are some people who are touting the benefits of using ATF in a Harley primary. What are your thoughts on using ATF in the primary vs your 4T 10W-40 motorcycle oil?

Answer:
Automatic transmission fluid (ATF) would probably work fine in your primary but in the end you will have to decide if you are satisfied with its performance. Every biker “feels” his shifts and knows his sensitivity to clutch slippage. Every modern ATF is designed with specific frictional characteristics that complement transmission performance with very specific friction materials. Depending on which fluid you choose, you may or may not be satisfied. And even then your buddy may try the same fluid and have yet a different opinion.
Sounds good, I just always worrie abt the trans gears an shift forks. There very expensive, ive got over five hundred in gears in my 86 an my new motor ,88 up I've got more than that in its gear box
