You can get away with engine oil, but strictly speaking the oil you use should have good anti-foaming properties. ATF or powersteering fluid works ok, some types of engine oil can work fine but others will work for a while then after a few miles may get too many bubbles in it and stop doing the job so well. But for the money you may as well use fork oil. It aint that expensive on ebay. Gasket kits on ebay are only about £20 too.
You can also find cheap piston kits on ebay. £58 for a set of three with rings is a bargain! http://www.ebay.co.uk/itm/251303823544? ... EBIDX%3AIT


yeah, ive already bought the new pistons and rings set, already have my bel ray fork oil in. thanks tho.

all i need now is to send the crank off and decide weather im going to get the jugs honed or just deglaze them and put in the pistons. if anybody has any ideas i would appreciate your feedback. basically just asking about reliability... if i give the jugs a quick hone/deglaze will the piston rings seat properly and be fine for a bunch of miles if the motor had good compression before the teardown or should i bite the bullet and take them to a shop to be sized for each individual piston.

never installed new pistons so just kind of wondering which route is best. like i said if its not really needed to send them to a shop id rather not. sorry for the noob questions but thats what i am sort of.

I'm not arguing your point. But, I've been using motor oil in my forks since I was in my early 20's and never had the slightest problems using it. Manufacturers will tell you a lot of things to get you to buy their products. Motor oil may foam under certain conditions, like it being extremely hot. But, I can't see any kind of oil getting to that point in a set of motorcycle forks. ATF has been used by many people for decades without the slightest concerns. I like motor oil because I can adjust compression and rebound depending on the viscosity I choose and using forks that have no adjustability.

Me three. And it's cheaper too. I love a bargain!!!
Think of how stupid the average person is, then realise that half of them are more stupid than that.
