transmission oil

[bloodswet&gears]

has anyone ever used atf in their transmission, or will it cause damage? i think i used to use atf without trouble but its been about 10 years ago and i cant remember.

use type F ATF and change often!

it wont do damage just dont forget to change it in a couple of years:)

i havent owned a 250r in about ten years. i wouldnt never let the fluid go that long. sorry. and thanks for the help. i was tired when i posted that. the last 250r i owned , i think i used atf & the clutch felt better than if i used 10w40 engine oil.

correct me if im wrong is it type f that has grit(lack of better word) in it. Is that what you are after with the type f?
I use ATF as well but it is a smooth fluid dexron mercon and it seems to really work well.

yes you can use type f atf. would i reccommend it? not at all. i would defeneatly get honda hp trans oil.

I have used ATF in all the 2 strokes I have owned. Never had any problems with it. I have tried a lot of different brands belray, honda, Maxima etc. The clutch definitely feels better with ATF too. I actually have a friend who drag races his Banshee. It runs 6.70 in an 8th mile and he has always had trouble with his clutch slipping. I told him to try the ATF and he hasn't had any trouble with his clutch slipping since.

it does help the clutch stick, but what else does it make stick? prolly bearings and bushings. Its for the most performance only, not the most protection possible.

i too use atf(in the drag bikes) but i use dextron. i heard rumors years ago from transmission builders that type f contains graphite. i cant validate tho. :(

I look at it like this all of the truck manufacters use ATF dextron in their 4WD /AWD transfer cases. There is a whole lot more gears and bearings in one of them than a pi--sy a-- 250r gearcase. just my 2 cents

I personally have never had one apart but I can only imagine.

but isn't graphite a lubricant? mine says dry lubricant on the tube.

it is but, based on experiences of others. isnt suited for the wet clutch setup in atv's. especially in those that have a much higher horsepower. it tends to promote unwanted slippage and therefor a shorter life of the clutches. i spose it's the same principle as using an automotive oil that has slip modifiers? :ermm:

[regg187]

yeah, I can see that, same reason not to use synthetic ---too slippery.
