Brinn tranny fluid

Anyone ever try motorcycle oil in there tranny?Wondering if it would be better than conv. 20/50 as in made for wet clutch also

I would only use what they recommend. I know they used to say not to use any synthetic or blends as it would damage the disks. They also did not want you using ATF like the BERT for the same reason.

I called them two years ago and asked about fluid and was told if im using good engine oil just put the used oil in it after we changed engine oil. Ran it for two years with no problems and couldnt beat the price
