Good day gentleman. Find myself in a confusing state. Got back into repairing a 96 vn800 classic after thr PO dropped a valve and blew the front cyclinder. After fixing er up i noticed it had a coolant leak. Only thing i can see to replace is the mechanical seal. Ordered up a new one to discover that it doesnt fit. Looked up parts numbers and diagrams and they all say it os the right peice. But it doesnt match up with the seal i pulled outta thr bike. Anyone have any experince wit this?
