Question
We are an ATV/motorcycle repair shop.  Customer has a Honda 305 Scrambler -- needs engine work.  Not sure what year this bike is -- are looking for piston & misc. parts.  Is there microfische available online?  Where can we purchase OEM and/or aftermarket parts?
Thanks very much!

Answer
Dave, I have written extensively about all the 250-305cc models and have CDROM versions full of all the info you need. The CDs contain parts manuals, owner's manual copies, restoration information and Engine repair manual information, too. I can also provide an electronic ignition system that will help in timing the engines accurately. The stock point system has wobbly point cams that cause timing fluctuations, even when new.

See my www.vintagehonda.com site for more details and to send email direct to me through the site about books and ignition systems. We have resources through the VJMC.org site to assist in restorations. A good friend Ed Moore in TX has done a lot of motors and restorations, especially on Scramblers.

305 Scramblers began production in 1965 and had SLS brakes front and rear. These are rather marginal for daily driven, so Honda switched to 8" DLS brakes which are much more powerful and useful for riding on the roads.  Ebay can be a source of parts, as well as www.westernhillshonda.com in Ohio....

Hope the bike is complete as many of them suffered loss of chain guards, stock exhaust systems and bobbed front fenders/stays that are scarce and expensive when you find them. I hope your customer has a realistic expectation about the costs involved. A motor job can cost $1k depending on how it was treated and how many miles are on it.
There are no on-line microfiche services available for this bike. Parts changed substantially through the production, so giving the frame and engine numbers is important when searching parts.

There is a Yahoo group ... honda305 that has an email list of enthusiasts who specialize in these old bikes....
