Ditto, and AFAIK all LC pipes have the same washer installed.

Well there ya go, learn something new everyday, I dont remember these in any of the pipes I pulled off back in the day, but its been a while and no one ran standard pipes for long, and of course aftermarket wont have anything like a restriction in it. To be honest, I've never had a problem getting the gaskets in as they locate in the cylinder and the pipe centers itself on the spigot and the flange bolts, anyway I asked about these in my F1 thread half way down this page: viewtopic.php?f=5&t=4650&start=705#p140234" onclick="window.open(this.href);return false; and since no one answered at all so I whipped them out, easily done.. and they can go back in if i wanted but theyre gone now and ive a minimally less restrictive exhaust so it works for me :smt023

Re-filled and sanded the last of the damage on the Lc pipes and they are now ready for paint when I do the F1s pipes. :)

Yesterday got the cylinders back from the reborer with them all bored and honed to fit the 64.5 Wiseco pistons I bought ages back. I have cleaned up the threads and dressed back the inlet manifold area to make sure there are no sticking up threads or chunks of alloy to ensure a tight seal. Just need to give them a full clean up in the parts washer and paint them along with the head and theyre done... and apart from the head gasket (as discussed elsewhere on this forum) I think I have everything to build this motor now, wahooo!

With the cylinders back from the reborer they (and the head) received a huge clean up at a mate’s workshop where I was able to use his super luxurious powered and heated parts washer, wonderful in this winter weather! After a rinse and a comprehensive blow dry, the steel parts were coated with a marine vaseline from a tin that looked like WW1 army issue that was in the shop. I did that as these wont be fitted just yet and bore protection is key.

As I had already hit these with aircraft paint stripper a while back they just needed to be totally clean for the new paint, so after a final wipe over with wax ‘n grease remover and some time spent masking I was I was almost ready for a coat of VHT Satin Engine enamel.

The final job was to dig through my boxes and find the 2’s I had created ages back to complete the engine size on the sides of the cylinders:

Image

Image

Full story on why I needed the 2’s is here (almost at bottom of page): viewtopic.php?f=5&t=12311&start=75" onclick="window.open(this.href);return false;

These were glued on with JB weld and left to cure. Ive found that JB weld is a funny thing, its quite dependant on weather and to achieve a full cure (so the rubberyness is gone and its sandable) can take a couple of days.

The head was easier, I only had to tape up the joint surfaces for the top hose, the head studs and thermo were easily covered with washers. Simple and effective.

So, Here we have a very rare machine, the Australian spec only 4L0 250cc cylinder!

(paint just done at this point, so looks glossy, but will dry Satin)
(whats the betting this pic turns up on some other forum in a couple of years where someone argues that there really was a 4L0 250 in Aus... hmm... I should rename the pic as 5E1SP or something LOL. I blame google images who will link this without a thought and then some pinterester will claim it as theirs... in the modern world there are so many who copy and claim. Let's watch it unfold [smilie=eat.gif] )

I know what ya mean Jon. There is a guy on Sook Book who re-posted a lot of my Salt Vids as his own. The ones of the TZ750 on the Lake were very popular. I dont post on there any more.

Nice work as usual Jon.

hmm, that really annoys me, Ive had people copy whole pages off my websites and claim them as their own as well, wankers. I dot mind helping people, but to claim someones else's work as their own is just pathetic.

Oh and thanks Dave!

Next task on the list was to complete the resto of the footrests (set for me and a set for my mate who owns the powdercoating setup). These were the usual well used, dirty, oily and trashed items you get on well used LCs so needed a lot of work.

There were cleaned, polished, glass bead blasted the non polished areas and then crystal clear powder. I will say that when initially polished they looked too bling, but the powder has dulled it a bit, and also brought up the finish on the bead blast, pics are really crap sadly as on my phone, actual results were really very good on such old cast trashed parts.

Either way they all look a billion times better than they did and I doubt that different from new in the hand.

Polished:

Powdered:

For those who like ‘during’ pics...

Powder:

Powder on:

Cooking at 200degC (measured with a thermocouple not trusting a domestic oven for that!) as it says for 10mins.... Once the powder starts to flow:

And out to cool:

Thanks mate, its appreciated. What amuses me about the 2s is that back in the day people crafted these from body filler if they were bothered and did it with files, most just gouged off the 3 and left it as it was, pathetic really. These days with more time on our hands and better products Im still using an old school product (JB Weld) but with the clever moulding bar off a plastic part kit and its worked like a charm and they came out really nice. Back in the day if we'd have had ebay I could have sold a bunch of these to people like me haha! :D

Thanks. I used various high grade wet and dry and then the machine in the background of the last pic above to get the finish, then hand finished the edges again after I blasted the non polished areas. The LC footrests are polished all the way round as well as the front, when Yamaha got to the RZ they were only polishing the fronts LOL. Amusingly on the RZ footrests the glass bead finish really does look like the OEM cast finish, the LC isnt quite a rough but this is close enough in real terms, very very few would notice LOL

One thing to note, you really need to clean them well with something like brake cleaner and the off gas them in the oven first to give them the best chance at taking the powder without any bubbles. These are cheap alloy castings and theyre old, plus they been on a bike in an oily environment, none of this is conducing to getting a good powdercoat. Take your time if doing this, cleanliness will pay off for sure.

I took a couple of better pics yesterday:

Looks dull in this image, but its more like the edge closest to the camera of course.

And yes I blasted and powdered the backs too:

Sat here typing this with the gentle smell of rocking horse poo wafting up from the newly arrived packets on my desk... ok, maybe not... its really just the mild acrid smell of Yamaha’s rubber mix, but to my mind it brings the same... er, ‘joy’. :)

I guess there is a moral to this post if i’m honest... One I already knew but like everyone else, don’t always follow. ie: This post is a lesson really in why you buy things when you see them, and not when you need them.

In 2015 you could buy RD350LC cush drive rubbers from Fowlers, CMSNL and even Yamaha dealers. Just make the call and they turn up. By the start of 2016 they were NLA, both Fowlers and CMSNL occasionally listed 1 set each and who knows if that was just a system glitch*. The production had probably halted years before but finally stocks had dried up. In 2015 I saw a few sets go up for sale for cheap but didn’t buy as I didn’t own a 350LC rear wheel, only the 250 version which uses different cush rubbers. Of course, I should have bought them... In 2016 I managed to find a 350 wheel, itself a part only found under the back end of a rocking horse these days.

Over the past year I had idly looked for them every few months but each time came up either blank or they were in a part of the world that wanted silly money to post them. However my patience and persistence paid off last week and I found a localish (same state) place with a set and even managed to get a bit of discount (which didn’t mean they were cheap or anything) by buying 4 of their stock. Here they are in all their glory :)

Image

FWIW My supplier has one left if anyone needs one, but I’ll council that its a long journey to buy these in singles when you factor in postage.

* - CMSNL list some today actually, and I recently found out why. They bought all Tiaro’s Yamaha stock it seems who had some. An irrelevant fact for anyone not in Aus perhaps, but proves that CMSNL is actively searching out caches of NOS worldwide.
