hello.. i have just purchased a 1979 cx500 with 60,000 kms on it for $500 dollars. So far i´m happy with it. it seems to run well. It had a seized clutch cable, a little penatrating oil fixed that. the waterpump seal leaked, i have the old one out and a new one on order from Honda.. $70 inl taxes.. ouch!... I don´t want to give them more of my $$ . Does anyone know the part # of an aftermarket oil and air filter? Where to buy and how much? I live in Canada. Thanks..
