    1981 Yamaha SR250 Cafe Racer

    Hey Rod .. I was lucky enough to get a wreck a while back for a few hundred dollars that had a complete center stand on it. It's a pretty basic spring though, nothing fancy. Once the build is finished I may run just the kick-stand though.

    1981 Yamaha SR250 Cafe Racer

    Today has been an epic day of work on the bike! More was achieved today than in the last 3 months, I reckon. I started off at 8:30am making my way down to Port Kennedy to pick up the tank and seat from Mattpack. He also graciously helped me whip up a battery tray for the SR. It's quite...

    Still just tweaking the overall fit of the seat cushion but it's nearly there and though very firm, it's surprisingly comfortable. It'll get an additional thin layer of soft upholstery foam on top to cover any imperfections before the covering also. To reinforce the foam so that the vinyl can...

    This is the new stainless header I had Matt make up for the SR. I discussed it with him, showed him photo's of the bikes frame and told him I wanted the new header to follow the line of the down tube. I think he nailed it, good job Matt! The welding is incredible, so well blended it's very hard...

    As I welded the mounts on for the tank without the ignition coil .. I got a bit of a shock when I got the tank back and it wouldn't go on with the coil in place. Oops! So I made up some little brackets to mount the coil in between the spine of the frame and the horizontal bracing tube that runs...

    This is my rough idea for the rear guard. Substitute the cardboard for polished aluminium sheet. The tail light will be mounted on this just below the hump .. and the indicators just below the brake light either side .. and the number plate just below the brake light. I hope this meets the...

    The painted parts arrived this evening. Thanks to Matt for driving up with them. They're not polished yet so they need to go back to have their final polish and a blemish fixed up on the tank but I have them here for a week or so to finish off mocking up the rear of the bike. I also got the...

    1981 Yamaha SR250 Cafe Racer

    I fitted a piston-style steering damper this evening. I drilled a hole into the heavy-gauge bracing gusseted under the head stem of the frame to attach the damper bracket .. And drilled and tapped an m8x1.25 hole in the lower triple clamp to accept the threaded rod end of the damper. Simple...

    1981 Yamaha SR250 Cafe Racer

    A little bit of progress today. Got the seat in primer .. it still has a few bits that need filling (fiberglass is a bitch to get smooth as you can sometimes get little bubbles in it, even when you roll it) but I think I'll leave that to the painter now, I've done the best I can. Also I...

    1981 Yamaha SR250 Cafe Racer

    Hey guys, Yesterday afternoon my tail light came from Trojan Classics. It's an alloy body Lucas 525 replica. It's shape matches the profile of my cut down rear fender nicely, so all I had to do was drill a hole to fit it. I reckon it looks mint. I can't wait to have it on the bike for the final...

    1981 Yamaha SR250 Cafe Racer

    I had an idea for the underseat area. I had previously made up a tray and battery box to house all the electrics out of folded aluminium sheet. This was fine and nice and light, but it dropped down below the curves of the frame's subframe and I didn't like that. Then I thought .. maybe I could...

    It's all done now and it's looking good .. I've just finished extending the upholstery pan. Now I just have to fill the gap with foam and have it upholstered. The seat pan is basically done now so hopefully I can send everything off to the spray painter next week.

    This afternoon I finally got the seat pan finished and ready for paint. It turned out great. I also stripped the paint from the tank ready to send it off to the panel beaters hopefully next week. Here's the side of the seat. I'm really happy with how the bottom of the side panels follow the...

    1981 Yamaha SR250 Cafe Racer

    Here's the seat with the side panels glassed on and shaped.. I chose to flush the joins with body filler rather than fiberglass as it was easier and I would have ultimately needed filler anyway. They are very strong (I used about 3-4 layers of mat) so strength is not an issue. A bit more...

    1981 Yamaha SR250 Cafe Racer

    I decided that the side panels were the way to go, so I made up a jig with some ratchet clamps and some particle board to give me something to lay up the glass against The sides layed up. Once these go off and set, the jig can come off, and a single layer of chop mat will be layed up from the...

    I've decided on a tail light .. going for a classic Lucas 525 tail light. Will order it ASAP and get onto mounting it. Does anyone know where I can get the glass and reflector for my headlight? I have repainted a bucket and have a NOS headlight rim but can't find the glass and reflector new...

    So far I've had only a few scratches that I've had to touch up on the frame. It won't take sharp edges or rubbing like powder coat will, but it's definitely stronger than your average paint. Did you clean all your parts with warm soapy water and air dry them before your top coats? Use thinners...

    1981 Yamaha SR250 Cafe Racer

    Had a couple of hours after work to fiddle with the bike, so I decided to get the seat mounted. In the last post I didn't show the mounts bolted up to the frame, so here's an underside view of the rear tank mount. Everything is set up so there's clearance under the tank (~10mm) to the frames'...

    1981 Yamaha SR250 Cafe Racer

    First thing I did today before I started welding on the mounts for the tank was weld up all the holes created when drilling out the spot welds on the old mounts. Now you see them.. And now you don't .. I then tacked the mounts on to the frame, I'd already measured and marked up where they...
