Just wanting some info on fluids got aclutch coming from nrhs on order ,and would like to know what you guys with E1 cluches have used as your primary oil

cheers

Just replied to your PM sent before I saw this.

Slap.

 no probs slap could you find out off your guys what they put in her,just abit weird putting atf in hey

ATF wont hurt the clutch plates (think auto trans clutch plates). I have a customer that uses Redline ATF in his primary (dyna) and has no issues. For a sportster i'd be looking at using something else as ATF is a little on the thin side for the harley gear boxes. But to contradict myself im currently using Mobil 1 v-twin in my box/primary and its been great.
 

Give it a go.

 Yeah thx t1 ,energy recommend to use b&m trick shift ATF ,but iam thinking the same as you too thin,dan from nrhs said he uses Mobil 1 75/90 gear oil but its a syn

Nothing wrong with syn oil in the box/primary dude. I'm always trying different brands/types of oils in my bike, so far the Mobil 1 v-twin engine oil (syn) in the primary is going well, shits better and a little less "clunk". The only thing you need to be concerned with is if the oil you choose will damage the clutch plates and if any additives will "hurt" the bronze bushings....otherwise go for it and try it out.

 i use atf in the pri on & off off years since the 80's ,  i use it in the fraser dyna 120R as well , i have & XR1000 &  on the factory race prep spec sheet they say atf & that's from back in 1983/4  from the factory XRTT 1000 that won the BOTT race's @ Daytona 1983/4 beating up the ducati's too win both years 164mph on the banking @ Daytona the Devil's Hammer

Took ya time Daddyracer, was wondering when you would post!!! 666 i think you have your answer now. Go for it.

 i'am a bit older & slower these days  only  ,  fast on race days ( FORD ), atf is a bit hard too hold in the pri cover,  on the late bikes it's easier but on some earlier models when hot she can leak a bit here & there, you will have to change it quite often keep it fresh & clean as the chain will give it a hard time  , atf will not hurt the gears in the g/box , i use Penrite  ATF-33 for Drag Racing use

 Yeah had alook at penrite 75/90 mineral gear oil could be an option

 too thick for the clutch

 Ended up using amsoil ATF working well smooth shifts and good grab but I think I might try a min ATF think penrite make one?
