Tamiya Honda NSR500 1984


Recommended Posts

If anyone wants the photos and the full build write up for this please contact me via PM thanks!

 

Next up on the bench!

This one will take some time as I will be flying out to UK in a couple of weeks for a month. I bought the kit with the clear parts but I'm not sure whether I will use the clear parts or stick with standard parts. I have a habit of leaving off cowlings and engine covers as I am crazy about doing extra detailing on engines so thats why I originally bought this with the clear parts. Maybe if its possible I will do one half without the clear parts and the other half with.

I am hoping that while I'm on holidays that Top Studio releases a chain set for this, so fingers crossed for that

So I complained on another forum about a lack of a working chain and low and behold one of the members their gave me the information that all the Top Studio chain sets are the same size so it was really a case of the rear sprocket of the Top Studio set being incorrect. So luckily Tamiya have used their brains and have included the plastic chain as usual and then they have also supplied just sprocket on the sprue too! so this one will have a working chain like Ihad on my Honda RC166

Ok so not a huge amount done, mainly because I have been preparing for my UK trip as I have a fair bit of work to do while I am there. There will not be another update for over a month as I will be back home on the 23rd of September.

So here is the progress so far. I built the clutch and had to modify the kit clutch plate as the ones in the Top Studio set didnt match (which you will be able to see in the pics below). That said, Top Studio have done a great job with the quality and fit of all the clutch components. I have done a quick picture roll showing the various steps of the Top Studio clutch set.

Packaging, here you can see in the top left of the packaging the 3 resin clutch covers that covers pretty much all the Honda clutches of that era except for the 84 NSR500 (which I only found out about after opening the packet), normally you would choose which of the 3 covers to use based on reference:

All together:

One of the resin covers with the assembly. 2nd pic below shows the bolts that go on the surface of the clutch plate. 3rd pic shows how it would look with one set of bolts on:

Comparison of the kit clutch cover and the Top Studio version (huge difference):

Cutting the kit clutch plate to get it the right thickness to fit over the Top Studio clutch assembly:

Modifications complete, I also smoothed the edges down of the kit part as it looked too blocky

Completed with Alclad Steel and PE bolt heads:

Next I began filling in the frame and rear swingarm with putty:

And rear swingarm primered, modified for the PE chain adjusters, and ready for welds to be added:

So I'm back from my holidays and I've managed to get over my jetlag finally!! On with the build!

Not much to report yet, just lots of filling and sanding work taking place.

I've almost completed the rear swingarm, just need the Michelin decal to go on which was not supplied in the kit so I ordered it from HLJ and hopefully the parcel will arrive by late next week.

The petrol tank on this bike is located at the bottom of the frame, I decided to try my hand at making weld lines with putty, not bad for a first time but once the paint goes on it will be easier to see how good or bad the job was done, luckily alot of it will not be seen as the engine will be sitting above where all those weld lines are. If the welds look really bad I will just sand them off and leave it as it is.

I also did a quick mockup to get an idea how the body panels sit on this one. I have seen some pics of how this bike is displayed in the Honda museum in Japan and so my aim is to possibly display it like that if its not too much hassle. Either way this bike will be displayed 'naked' as the main reason I chose to build this kit is because of the odd configuration of the exhausts and petrol tank.

Anyways enjoy the pics lots more still to come!

Next stages will be to paint the body parts and finish them off then I will move on to the engine and chassis.

Very neat clutch kit Imster and the frame looks good too now that you've filled the back. looks like a good kit?

Colin

Yes Colin, its a great kit and up to the usual Tamiya standards.

There are differences though between the kit and the reference pics I have. Basically on the Tamiya reference pics the cowlings are all exactly the same as the kit but on the majority of reference material I have found including pics of the bike in the Honda museum the tank and the tail cowling have air flow ducts. I can only assume that the Tamiya version is the original and the one with duct work is the modified version possibly after Honda had tested the bike.

Hi Imster,

I've also seen both versions of the body. I'm pretty sure MFH did this as their first bike kit and theirs was ducted but the Tamiya one isn't. I think you're right that they did both of them so technically they're both right :)

Also, have a look at the old nsr500 chain sets that Top Studio make (TD23093 - nsr500, '92-'02) and (TD23143 - nsr500, '89) as they look pretty similar to the one in this kit, if not the same. The only difference that I can tell is the spacers used on either side of the chain ring. Just a thought so the actual chain doesn't chip away at the painted chain ring.

Looking good so far mate, can't wait to see it finished

Thanks Draz, yes the MFH version has the ducting work on them, I considered making the slots but I have enough on my plate with regards to engine detailing so I will keep the cowling as it is

Thanks for the info on the chain, I plan to use the '89 chain set (TD23143) which is one of the ones you suggested. The spacers you mention are the ones that come with the TS chain sets?

Yeah they come with the TS sets. I've got both of them and from what I can tell the actual chain ring is the same for each one, I guess its just the width of the wheel compared to the swingarm that requires some of the spacers. You can probably just try them out one at a time and see what the best fit is.

Great work as always, loving the detail

Thanks KP :)

Thanks very much Willie, the link works and the reference pics are fantastic!

ahh yes the rear sprocket, Tamiya have actually supplied a plastic rear sprocket without the chain molded in!

IMG_6213.jpg

So I should hopefully be able to use the kit rear sprocket without having to worry about spacers etc, fingers crossed eh!

See how you go with it mate, I only brought it up because they supply a separate chain ring with the 2009 M1, when I built mine I used that instead of building a photo-etch one and it didn't fit the chain that well. It was a really tight fit and it started chipping off some of the paint from the chain ring. Although, to be fair to everyone concerned, I probably over-did it a bit with the primer/paint on the chain ring which gave it some 'volume' and it was my first chain build so it probably wasn't the greatest chain, actually, it definitely wasn't. Sorry if it sounded like a criticism, I just didn't want something like that to ruin what's looking like a fantastic model so far.

Regards,

Draz

Its been a while since my last update sorry about that but its been a busy few weeks and my time building has been somewhat limited.

I have been doing some work though and its all bits and bobs but eventually it will all come together and hopefully look alright :)

To begin I received the optional decals which include the Michelin branding on the rear swingarm and the tyres. The swingarm is getting near completion just need to add the chain adjusters and a few tiny details and it will be complete

IMG_7359.jpg

The rearsets are pretty much ready for paint. I used the Hobby Design PE parts for this but I modified the PE parts so I can fit some of the old plastic parts back on as I noticed the Hobby Design version has the rear brake actuator going behind the cowling brace whereas the correct routing is in front of the cowling brace. I decided to use the plastic part and shave a little of it out so the brake actuator can pass by it without and problems. The actual actuator itself has been modified, the brown line will head upwards to the rear brake resevoir and the connection pointing downwards will connect to the braided hose at the bottom of the pic, that line will run to the brake caliper.

IMG_7356.jpg

Next up is the Top Studio chain, this was my first chain and I gotta say although very tedious and time consuming it was very good fun to build. After having built the Tamiya chain from the RC166 I gotta say the Top Studio chain is much more sturdier and in close up looks much more authentic. The cahin itself is not 100% complete as I will have to measure/determine the length that I must build the chain before completing it, once I have the back end complete then I will be able to measure it all up but by my calculations the chain needs to be 145mm in length. In the picture you can see the difference between the plastic chain and the TS version, also the front and rear sprockets are shown. I have looked at the rear sprocket and it seems that the TS version is slightly different than what is 100% authentic so I checked the plastic sprocket to see if it will carry the TS chain and it doesnt as the plastic is too thick and the teeth are too far apart. So I am left with a choice to either use the TS set which has a very slightly different rear sprocket (the correct version sprocket is flat, whereas the TS version has a little step in it) or use the Tamiya plastic set, and I chose to stick with the TS set as it looks so much better.

IMG_7355.jpg

I also started painting the cowlings. I will be painting the Red and White but not the blue as Tamiya supplies the decals for the blue parts which means less masking for me!

Colour coat painted

IMG_7337.jpg

1 coat of 2k clear applied (not polished yet) ready for the decals

IMG_7357.jpg

Thats it for now, my next update will be dealing with the brakes, lots of parts as you can see in the pic below and there are quite a few tiny detail bits as well

IMG_7353.jpg

Thanks for looking! As usual C&C welcome :)
