It’s just not worth it to go nuts with it.

The cb450 is such a pain in the ass to work on. Taking the tank on-off a bunch is super annoying with the cross-over tube, you get gas everywhere. The motor has to come out of the frame to do any real work with the cylinder head. The top-end has heat / oiling issues once you start adding more power, so now you have to figure out an oil cooler setup which is a pain in ass. Cam followers are an issue too. All said and done you put in a bunch of time, effort, money, and it’s still not really that fast.

Just keep the cb450 close to stock and enjoy it for what it is. It’s a great, super fun, around-town, zippy bike. I love mine for that. My buddy and I rode a cb450 and cb500t from Philly to Denver and back, in Sept 2010. Go back through Blog posts on this site and you’ll find it. That type of trip riding is def doable on these bikes, if kept in stock form.

If you want a bike to do real performance racing stuff with, go buy a cb750, kz650, kz900, or kz1000. Honestly, I’d also choose a cb550 four or cb650 to make into a performance bike over a cb450 at this point.

Hope that helps.
Ed

I’m already pick pretty much the same parts you used so jm feeling better about the part selections I’ve made. Just curious why you disliked the previous build so much though. I know the leaking and all is an issue but I was thinking of doing a second clone of the one I have and making it a primarily track bike so some detailed input would be appreciated.
