MT250 Knobby Vintage Streetfighting Cafe Scrambling Rat Tracker

I got the CB77 tan, and really like every last bit of it. Also cool that it's Honda, as much as the idea of pulling from as many different manufacturers as possible, the tank is where the brand is always displayed and the core of this bike is Honda, so it's nice to have a correct brand tank.

I'm about a million steps down the road from what I'm documenting here, and if I had it to do over, would have chosen a different order for all the steps. At the time it seemed totally logical to build from the front to back. I thought that it made total sense to build the seat, then the cowl. But if I had to do it over, I would mount the tank, then make the cowl, then just fill in the space between with seat. But I didn't do that. Instead I had purchased a battered old Ducati Monster seat off e-bay because it had the closest shape to what I was looking for. I figured I'd just chop it a little here and then and mate it to the tank. I also imagined that I would just slice off the rear of the seat to use to make a mold for a carbon fiber seat cowl.

Here's where we're starting:

The ergonomics are actually pretty good even for a tall guy on a small bike.

A co-worker's husband does hot rod upholstery and wanted to do my seat. Turned out just how I hoped it would. I perfer a real seat as opposed to the minimalist flat, block seat on lots of cafe racers. I wanted the lines to flow into the lines on the tank.

So I started working on the seat cowl. I have worked with carbon fiber a bit in the past, but it was always sort of amateur. I thought that this seat cowl would be a good opportunity to learn how to make a mold and vacuumm bag the cowl.

This was the step that has absolutely dominated this build. I was determined to get it just right. Of all the things on the bike, this will be the biggest piece that I create on my own. Most other things will be cobbled pieces from other machines. So I really, really wanted to make it perfect. Spoiler alert: It took me around 8 months. For real.

I started by applying some 2-part resin to the foam chopped-off the back of the original Ducati seat.

Here's a little sneak preview... That's a CR250m cylinder, DG head and 35mm TMX, flat-side carb to push my clown tire around. But first we're going down the rabbit hole of building the seat cowl. Hang on it's about to get OCD.

Hey. I see that you spend a lot of your personal time sitting in front of your computer posting on this board (Over 4000 times in just two years!). I don't spend a lot of time on the computer or the internet, so I have never had to deal with someone posting unsolicited and generally negative comments about my work. Rather than get into a posting argument on a public board with you, I'm going to PM you my phone number. If you feel so compelled by what you see here that you need to tell me what I'm doing wrong, by all means call me. Or, given that you are in Grants Pass, OR, next time you ride your motorcycle to Portland, why don't you swing on by my shop in person and tell me. Otherwise, to quote everyone's mother: "If you don't have anything nice to say, don't say anything at all."

Or, maybe don't read my thread...

In any case, to the presumed relief of other readers, I'll be ignoring you while I build my bike.

Thanks,
Alex
