11/9/2023 8:01am Nice! I didn't know that they don't do the Vintage Garage anymore, that is a shame for the spectators as that is probably the only time they can see bikes like that up close as it travels around the country. Kind of a pain to setup and tear down but I was glad I did the effort to have mine...

11/6/2023 4:40pm The guy that owns that Vincent was all about my Big Horns, asking me questions, ect... When we were loading out. I would have to look up his name, but I think that is the correct color. Anyways about the Erie show. I am familiar with the club that puts that on. I used to attend that show when they...

11/5/2023 3:32pm Thanks. I would have to get into shape to even try to ride a decent lap on my "hot" Big Horn. lol. I should get out to a vintage race sometime just to watch as it has been a really long time since I have been to one. I most recently had both of my Kawasaki Big Horn's invited to...

1/21/2021 9:45am Yep, these are it. I can't remember what weight oil I am using otherwise I would tell you. I know in my stock F5 I used ATF as previously mentioned (if I remember right ATF is offered as an option in the manual). I might have in my "race F9" but I really don't remember now. That is all I...

1/21/2021 7:37am It is looking good! To answer a question about damping adjustment on the Hatta's. No, they just feature preload adjustment only. However, on the sets I have dis-assembled I have noticed the the oil passage holes were rough from manufacturing. I did an ever so slight chamfer on each hole and then ran a file to take off the interior...

I have also been busy on some fabrication: I made my own bike stand out of 16 gauge sheet metal. I had some metallic blue paint leftover from another project that closely matches the F4 tank, and duplicated the kawasaki logo off the tank and cut it out on each side of the stand. 
The missing bearing for my rear hub showed up so I test fit my rear bushings and everything fit just right including the rear sprocket alignment. I decided to mount my ignition coil (originally mounted on the battery box that I removed) up inside the...

1/8/2021 2:51pm I wanted to pop in and say I really like this project! And it is looking good so far. It is a lot like my F81M replica, using an F9 as a basis. https://www.thejunkmanadv.com/kawasaki-f9-project.html https://www.thejunkmanadv.com/kawasaki-green-streak.html
