dude you need to run some better oil
i run klotz supertechniplate
I run lucas synthetic availible at O'Riely's @ $6.00 a quart and house brand atf type f in the gear box @ $3.50 a quart
pro honda hp2 ran it in my blasters, ran it in my dirt bikes, run it in my 250r and i even run it in my snow blower
Are r50 and supertechniplate pretty much the same stuff?
My friend used that stuff in his Blaster....It blew up 2 days later....
