just turned 20, with zero motorcycle experience. My brother and restore old klunker beach cruisers a lot and we got into Whizzers from there. I'm making the jump to motorcycles now and since I like learning things for myself I bought something to restore.


I do have a great resource for all things motorized though, I'm a student At Western Washington University and Vehicle Research Institute. Thats were I'll be doing all the work on the bike. I'm just turning to the forum here because I need help with the specifics. The VRi does a whole lot of building cars and breaking them not restoring motorcycles.

we do have 2 of those Honda CBX inline 6 bikes upstairs thought

I'm going to get some penetrating oil tomorrow and I'll try the bolt again. Should I worry about breaking anything if it is really stuck or can I just work on it as much as I want? I stopped working on it the first time I tried it because I thought it was going to crush the magneto.

thanks

Carson

I thank you for all the information you gave because your requests for help caused me to feel that you are a neophyte (not stupid but ignorant) with motorcycles. That said all of us will now know/better understand at what level we need to help you with any questions you ask. Of course I for one will be interested as to how much the instructor will be of help/understand/know of the mechanics of your bike. Although I'm not one with all the answers to these bikes I do my best to help others with these bikes. I think that anyone working with these bikes really needs to consider that "these bikes are just machines" and need to look at and consider how that darn part really works. Get in there and let us know how the class goes. ......................lm

yep certainly ignorant about motorcycles. The Whizzers are so simple theres only so much you can learn from them before you need to move to something bigger. Two stroke, single speed, they were great for starting out and learning. Heres a picture of my brothers that he finished building this fall.

I have dealt with 5 or 6 of these engines in a frozen state. I have luck freeing a couple of them up with PB Blaster, and patience . The thing is, every one of them needed a complete rebuild, as the bore was rusty, rings were stuck to pistons etc. So even if you do get it to turn, plan on tearing the engine down, top end at least. With the Bill S books, and taking the time to undersdtand how everything works, it's a pretty painless operation. I have a blog under restorations on a CB77 engine rebuild that is in progress. Check it out when you get a chance. Good luck, and please keep us posted on your progress.

thanks, I'm going to start taking it apart this next week. I have some other projects i need to wrap up before I tear into the bike. So you managed to get them back running without having to bore them out and drop new pistons?

Where in Marin are you from? I was born in Mill Valley and so were both my parents.
