Registering a Small Motorcycle in the State of Vermont

March 16, 2020

UPDATE: Recently the State of Vermont eliminated the method I describe below for registering out of state vehicles, which is very unfortunate (it really sucks!). I don't know of another option that is comparable to what was available with Vermont, but West Virginia just implemented a new program that allows out of state businesses to register vehicles in that state, so hopefully in the future that process will be expanded to include out of state individuals also. Registering a Honda CT90 in Vermont This post shares in detail my experience in going through the process to register a Honda CT90 in the state of Vermont and then take that registration and use it to get a title here in the state of Washington. I'll explain the process and then share actual copies of the my completed application and what I received back from the Vermont DMV. I have purchased a number of CT90's that didn't have a title and with the ones that I planned on keeping, I have gone through the...

For Sale - The Original Made in the USA CT90, CT110 & CT200 Clutch and Headset Nut Tool

October 26, 2019

As of 4/4/2022 I have decided that I will no longer make these clutch holding tools. I have provided a file of my design that would enable you to make you own copy of the tool here at this link . As of May 26th of 2021 I am now out of stock of my tool. I am looking into making another batch, but the outfit I use to laser cut my tool has increased their prices significantly to where it may not be worth the effort to continue to try and sell my tools, especially given how cheap the knock off of my tools are coming out of China. I'll update this post if I do end up producing another batch. I do want to thank everyone who has purchased one of my tools as it has been an enjoyable experience (except for the knock off's from China...) and I hope you have found the tools useful. When working on a Honda CT90 two of the most frustrating things can be trying to hold the clutch basket while loosening the nut that holds it on and also loosening the special headset...

Product Review - Memotronics ELF33-6 Turn Signal Flasher

October 07, 2019

I have a 1975 CT90 that I have never had the turn signals work all that well even though I replaced all the bulbs, picked up a new stock flasher, and cleaned the truncates signal switch and also went through and checked and cleaned all the grounds. While I did get some improvement after taking all of the steps described previously, they still didn't work like they should, so I decided that I would take the next step and look at converting my turn signals to LED bulbs. In making the change to LED's I knew it couldn't't be a straight swap of the bulbs only and that I would need to change the flasher to a configuration that wouldn't be dependent on the resistive load of the bulbs to cause the flasher to function like with a stock CT90 flasher. So I figured I would do the upgrade in stages and first buy a new flasher that works with LED's and with a little searching on Amazon I found the Memotronics ELF33-6 Turn Signal Flasher that had good reviews.

CT90 Engine Exposed!

August 26, 2019

I was finally able to get around to doing a project that I have been wanting to do for some time and that was to take a bunch of extra CT90 engine components and build an engine using cases that I had machined to end up with an engine that would enable you to see all of the internal components.

A Step by Step Engine Reassembly Guide for a CT200

May 24, 2019

I recently picked up a CT200 that wasn't running, but seemed to be in decent shape where the engine would turn over and had signs of good compression. I had rebuilt one CT200 a couple of years ago and sold the bike and since that time I started this blog and because I have had such a good response with the post I did on reassembling a CT90 engine, I decided to take the time to go through the engine of my new CT200 and document the reassembly in this post. Another reason I am going through this engine is that this may end up being a bike I will keep for a while and it seems like all old CT's that I pick up have slime in the engine and the clutch will end up slipping sooner or later, so now is as good a time as any to tear it apart, clean, and then reassemble the engine to avoid any problems in the future. I plan on taking the same approach I did with the CT90 engine reassembly post where I document in detail the step by step process on how everything goes back together...

Honda CT200 Engine Fasteners

April 16, 2019

I put this post together as reference for the length of the fasteners used in a 1964 Honda CT200 for assembling the engine cases and covers, but also for some of the fasteners used internally within the engine. Screw size convention Example: M6 x 1.00 x 20 M6 - is the diameter of the screw, which in this case is 6mm 1.00 - is the thread pitch of the screw in threads per millimeter 20 - is the length of the screw, which in this case is 20mm On a few items like pins and a washer I provide dimension in inches instead of mm. Clutch Cover Screws Four M6 x 1.00 x 20
