Honda CT90 Engine Reassembly

Image
I have one 1971 CT90 where I was going to rebuild the clutch because the kickstarter just wasn't turning over the engine like it used too,  and I also had a Big Bore kit from DrATV that I wanted to install. My intent was to just do the top end and rebuild the clutch with new disks, but when I opened up the cases to rebuild the clutch pack I found a slick black slime in the bottom of the case.  I didn't like the idea that there could be black slime in the rest of the engine, so I decided to disassemble the entire engine to make sure I cleaned everything out.  Since I was tearing everything apart I thought I would document step by step how everything goes back together in this post in case others were interested in knowing what the inner workings of a CT90 engine look like.

CT90 Machine Shops

Machine Shops that do work on CT90's
This page is currently a work in progress and I may change the format as I get more recommendations of shops that do work on CT90's.  The idea behind this page is to create a resource for people who may be new to working on motorcycles and are looking for a shop to bore out a CT90 cylinder.  For reference, the typical shop will charge in the range of $40 to $60 to bore and hone a cylinder when you supply a piston.

Know of a good shop?
If you know of a good shop that you would like to recommend that is located either here in the US or anywhere else around the world, please send me any contact information you might have like address, phone number, website url, if the accept work by mail, etc.

Thanks everyone who have already made a recommendations and I hope this info is useful for anyone needing work done on their CT90.

Here is a nice link to a website that does a good job at explaining what is involved with boring a small motorcycle cylinder yourself using a rigid honing device.
