Full strip down.
Permalink  
 


My TTR 250 only got delivered today and i'm already thinking of getting the frame powder coated. It has quite a few bits of rust around welds and the subframe has rust under the rear fender.

This goes against my OCD smile i hate rust and think there's a bit to much to sort out with spray cans. I'd also have to remove many parts if i wanted to touch it up. 

From peoples experience on here how long does it take to strip it down to the bare frame ?

Anything to watch out for ? ( i know there could be seized bolts etc).

Andy, your best source of details would be HERE on one of Brian's refurbs.

If there's anything ever been done to a TTR I feel sure you will find answers to all you request in his excellent refurbs.

I ought to know - I'm still running one he did nearly 5 years ago.

Thanks Cubber that gave me some idea of whats involved.

Hanzo, yes i do like torque settings for the important nuts/bolts, i'll have a search for that manual.

I used to try wire brushing and touching up the rusty parts of TTR frames by spraying with aerosols but it is very difficult to get into all the corners to get off the rust. Wire brushing and emery cloth aren't particularly effective at getting off all the rust. I never fancied the idea of using chemicals on the rust being afraid of some residual corrosive action but perhaps that is an unnecessary worry.

Once I found that I could match or improve on the factory frame blue by powder coating then that was my choice for all future rebuilds. And it is so nice putting parts back on a lovely frame wink

Before I found a powder coater that could do the blue, my first powder coated frame was done in gloss black and very good it looked too - see the resto thread here. I stole the idea from the new Australasian TTRs where Yamaha started to use black frames so I had an idea what the finished TTR would look like.

It is possible to strip a TTR and box the parts in about an hour. Unless the bike is already very clean, take the tank, seat and panels off first and give it a thorough wash before stripping down. It will make the strip down a whole lot nicer and make the rebuild a lot quicker.

If you are not going for a full nut and bolt rebuild then you can keep some of the big assemblies together e.g. leave the front wheel in the forks and the forks in the yokes. After disconnecting the switch connectors blocks and throttle/clutch cables you can actually leave the handlebars fairly intact to keep with the fork assembly.

Also, you can take off the chain and remove the rear swing arm complete with wheel, shock absorber and rear brake assembly all still in place.

There are a few bolts that may prove a bit tricky to undo and can be helped off with an overnight soak in easing oil and maybe a bit of heat. If you haven't got an impact driver then its worth the investment. My recollection is that the tricky bolts are the two that hold the RH footpeg support in place and the bolts that hold on the rear mudguard and number plate holder as they get all the crud thrown up at them. 

To keep the parts safe, I use the big sturdy tray-style boxes from the supermarket lined with newspaper. Have some spare 6mm nuts so that you can securely fix bolts to the parts they belong such as the chain guard, rear brake master cylinder, rear brake switch, etc where the bolts are unique to that fitting.

For cleaning individual parts, I use a sink top parts washer which had covered the initial investment a hundred fold biggrin

That's all I can think of off the top of my head!

Suffice it to say, I find it very satisfying the end up with a TTR in near showroom condition and it has been what drives me through some of the tedious parts of a restoration.

Brian

Thanks for the advise Brian, yes thats what i though about the rust, just to much of a faff. I thought silver or satin black but you now have me thinking about gloss back now. I have a good local powder coater that i've used many times, they take care to mask the important parts and threads and always do a quality job www.redditchshotblasting.co.uk/ . I won't go for a full restoration/nut & bolt rebuild but i will renew most bolts for stainless and repaint anything that needs doing, i'll probably get most parts ready while i wait for the frame to be done.
Great idea with the spare 6mm nuts, good tip. I have thought about spraying the engine but to be honest it's not to bad, i'll do it if i get bored:) .

1 hour to strip down ! I think it will take me a day.
