What does the tecate look like? Does it have the radiator mounted above the forks? If so, you have an 84 or 85. The 86's looked totally diffrent. To tell between the 84-85, the 84 would have a drum brake in the front. There is no diffrence between the 84/85's besides the 84 having drum front, and 85 having disc front. As far as the Honda 185 flywheel, I dont see any way it would work. They are made totally diffrent. For fork oil, I would run at least a 10 weight oil. Bel Ray is a good kind to get. If you want to, you can put in heavier bel-ray oil to increase the stiffness a little bit (15w up to 30w) I would recommend going to a motorcycle shop when you buy this, they usually have it on hand. Otherwise, you can buy some out of the dennis kirk catalog. I hope I was some help to you. )
