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.

Options for Honda CT90 Paint

Given that most CT90's you come across are over forty years old they all tend to have a few battle scars and faded paint and show their age.  In some ways I like the look of an older bike and think it adds character, but sometimes the damage is such that you really need to remove the rust or fix the damaged plastic and apply a new coat of paint.  If you look hard enough you can find sources where you can purchase paint in the original colors or take color codes to your local automotive paint supply house and have them mix you up a pint, but if your like me and like to keep the cost of your project under control, you might look at the following paint options for your CT90 or CT110.

I have also recently updated this post to include a listing on Honda Paint/Color codes at the end of the post.




I have several 1971 CT90's that I am restoring and the Rust-Oleum Painters Touch Gloss Golden Sunset is very close to the Summer Yellow that came on those bikes in that timeframe.

I also have a 1975 that came in a Tahitian Red and I have found that the Rust-Oleum Gloss Apple Red is very close and is also just a very nice red.

I have been using the Rust-Oleum American Accents Gloss Dark Grey for the down tube cover and air filter housing on my 1971 CT90's and while it is slightly darker then the stock Honda silver/grey color it is very close.

The nice thing about all of these paints is that they can be used on plastic also, so if you're doing a low budget refresh on your bike these paints are a great way to go.

I ran across the following web page at this link that has some good information on what colors came on CT90's for each year they were produced.

If you have other good sources for paint or paint information related to CT90's it would be great if you could leave a comment below.

I also noticed that at Dr ATV they shared a great post here at this link from one of their customers on several options for paint that covers most colors used on all years of CT90's.


The following table has Honda paint code information for CT90's and CT110's and I also added some columns to the right to reflect the rattle can paint information contained in the DrATV link I shared above and this includes links for the paints available on Amazon.
