I just got my 90 na a few weeks ago, and it had been sitting for like 6 months before I bought it. I did not have high expectations as far as condition because I payed very little.

It is pretty slow before 4k rpm, but I figured it was either an ignition issue or something else. I decided to check my timing last night and it was waay off. I then checked by tdc markings and it was like 10 degrees off .


I just pulled the crank bolt off, it was only hand tight!!!! It looks like it has some old loctite red on it, but who knows.

Looks like I will be doing a locktite fix this weekend.
