So ive decided to turn my yz450f into a super moto/dual purpose. I redid all the cosmetics/bearings/suspension last winter so the bike is brand new. but it started knocking the end of the summer. all the top end is good so I gotta dig deeper so I'm doing a full rebuild. Basically what I'm wondering is what I have picked out to replace will suffice for a conversion to WR. here's a list of things I have picked out: WR450f bottom end rebuild kit YZ450f top end rebuild kit WR450f stator/flywheel/stator cover I have a number of questions I'm seeking answers to and wondering if anyone can help. 1. will the bearings and seals that come with the bottom end rebuild kit work with the YZF case. 2. Do I need anything else to make it work. 3. What gear ratio should I go with for 1st and 5th. I want to make both a little wider. 5th more than 1st. so its nicer on trails and on the highway. 4. how will changing the gear ratio of first affect second? should I just leave it be and go with just the WR flywheel and a wider 5th for the highway? 5. Any part supliers that you would recommend for the stuff I am gonna need? keeping in mind I live in newfoundland Canada. I appreciate any help you guys can give me!
