Yamaha YZR500 '83

After a few years of pondering, starting kits, but generally not getting anywhere, I seem to have got up some steam with this kit I bought as a bargain price at Telford in 2013.



I'm not so keen on the Taira livery, especially when there's the Marlboro one to do!



I'm generally inspired to choose kits that I can detail with extra wires etc. I'm not quite ready for a YZR-M1 with all the upgrades, so bikes from the 80's seem a good choice to gain experience. Hopefully I can get some of the detail in the next picture on to the kit. We'll see!



I've made a start with the frame, and most of the engine parts. All parts are put on to their 'sticks' and cleaned in an ultrasonic cleaner before priming. I've sprayed Halfords grey primer from the can but going to try Zero and Alclad primers next week.




I was looking for something like a dull polished aluminium look for the frame so I tried the polished aluminium Alclad straight on to the primer. It's a bit too flat, but I think if I'd sprayed over black enamel it would be too shiny. You can see the difference in the next picture.



I'll get on with some detail painting on the engine and radiator over the next few days.

Re: Yamaha YZR500 '83

Nice start! I have 3 of these in the stash, and I built this kit in 1994, (and still have it
in a display case). You can always flatten a metallic finish, so I sometimes go glossy
first, and flatten it to fine tune it. Love those cylinder heads! Marco

Re: Yamaha YZR500 '83

Most parts of the engine have been assembled.

The main block was spayed Alclad engine manifold, should be a browny colour but has come out a little darker in the picture. Alclad polished aluminium was sprayed on the heads with Tamiya clear red on the bolts. I've detailed the other bolts with silver and added rings just below the carbs using thin strips of foil from a wine bottle.

I'm pleased so far...

Re: Yamaha YZR500 '83

I think the tubing Tamiya supplies for the leads on the spark plugs is too thick so I added some thinner wire. I used "tiger tail wire" I found on eBay. It comes in various sizes and colours. Handy stuff for us

I took the Tamiya plug, cut the "nipple" off and then cleaned any excess material to give a smooth surface to drill a small hole in. Then I glued in the wire and painted semi-gloss black with a silver coat of paint ringing the base of the plug.

Plugs in!

What size pictures do you prefer, the larger as the above posts or this smaller size?

Re: Yamaha YZR500 '83

Depends on which forums you belong to, some forums limit pictures
to 600X800 pixels, so I have had to change my Photobucket parameters.
This forum seems fine with larger files. Carry on! You're doing great!

Re: Yamaha YZR500 '83

Done a little work on a water hose with clips added.

I got the shape on the hose by inserting brass wire in to the Tamiya wire, cutting it short so the ends were still hollow to allow easy fitting.

I manage to find the self adhesive aluminium tape I had to make the bands for the clip. Much easier than glueing foil from a wine bottle!

The screw on the clip is a small piece of solder. Placing this was easy once I got the right technique. Cut the pointy end off a cocktail stick. Put a dab of glue on the silver band with a cocktail stick using the pointy end, lick the cut end of the stick and use that end to pick up the tiny piece of solder wire and place on the glue.

Promising start! Great idea with the foil for the clamps!

Re: Yamaha YZR500 '83

It's getting fiddly now!

I just came across a build for this kit that showed part of the throttle control on the engine. Thought I'd have a go.

Will be fun getting the engine in to the frame without damaging anything!





I made the blue pulley wheel by using a standard paper hole punch on plastic card, drilled the holes and fitted the parts on to plastic rod. I painted it Alclad polished aluminium with clear blue Tamiya over the top.

Re: Yamaha YZR500 '83

I've been working on the cowling. I decided to remove the small details (bolt heads) with a fibre glass pen to make sanding easier. I've just got some tiny photo etch bolt heads to replace the detail I've removed that should look more realistic.

The part on the left is straight off the sprue, the right is cleaned up.

Nice work on the pulley!
Got to get myself one of those fibre glass pens. Do you plan to put the p/e bolts on before or after painting the cowls?

Re: Yamaha YZR500 '83

Thanks, I'm pleased with the pulley. I couldn't find any pictures of the real thing, but I think it looks right.

Most of the P.E. bolts will go on after painting. All the pictures of the bike I've found show them as shiny bolts apart from a couple on the front around the rider's number that have been painted over.

Re: Yamaha YZR500 '83

Radiator is done. Satin black with flat black hoses and hose clamps added. In the top right I've added the connection for the water temp sensor.
