50 or 90

[qcitytile]

I'm wondering if there is a way to tell if I have 50cc cases or 90cc cases. Any help is appreciated.

is your quad a 50 or 90 if you bought it new it going to be what the cc are .hence if its a 50 or 70 drr they are 50 cases . and a 90 has 90 cases. the crank on a 90 is larger. the clutch cover on a 90 is vented . give us more info.

I bought these cases used and was told they are 50 cases, but I want to make sure before I do any thing with them. It was in a box of parts so I'm not for sure on any thing. I was hoping that there was a easy way to tell. Thanks for the reply

if the stock cylinder studs are on them the 90 are longer studs

Match a cylinder up to them and if it closer to a 50 then 50 cases, closer to a stock 90 cylinder then 90 cases

The difference is in the volume of the cases, 50/70 fit a smaller crank then the 90
