SUN rims used to be real good quality, don't know what they are like now but they should be good for the price (unless Buchanans has a 300% mark up?)
Swing arm brace is a good idea in my opinion
Nope, I bent a coat hanger, then found it wouldn't fit where I wanted and started over ;D
I was originally going to make it AHRMA legal, but it wanted to be in the same place as the torque arm so I'm doing something different and bracing drive side only

I was thinking of bracing swing arm and welding a new tap for torque arm directly to front end of brace.
Moving torque arm out slightly would probably be a good idea to get a bit more clearance with a 110 tyre on wider rim
Going to be attacking the cases this weekend as they are dirty, very dirty!
Going to give it the full spar treatment. Kicking off with a kerosene bath and scrub, simple green and pressure washer clean then final scrub in the soda blasting cabinet.
Finishing touches are going to be VHT natural finish engine enamel. Anyone know who stocks it in Australia?
Looks like the cam chain has been slapping around a bit as its chewed out a bit of the case. Not too bad as there is still plenty of depth there to accept the rubber c damper. Anyone confirm my diagnosis?
Lastly, I will be swapping out the crank bearings. Do I put the same ones back in or is there some other technique to it? Here is one of them removed:

I'll start with a question for you Ed Where do you get your simple green?
Burson's down here stock VHT, but I don't think I've seen that colour? What's a "natural finish? Is it a clear? I used their "cast aluminum" on other projects and it held up well. The Supercheap stuff is rubbish IMO. POR-15 do a very durable paint as well, but the silver is just too shiny for a stock look.

Well. To do it 'properly' you need to have the clearances measured, then compared with the colour-code chart in the manual which will give you the bearing size. There's 4 (or5?) to choose from to allow for variations in manufacturing. It can get a bit complicated for those of us that don't do it much, and I've heard of guys having success with just "going for the yellow" bearings. I'm lucky enough to have an engine-rebuilding friend with all the gear and knowledge, so I took advantage of that ;D
Just had one of the locals here go through this with his 400-f, and he ended up with something like 3 sets of yellow, 2 brown (or something ???)
Not sure what you want to do with any of this info, but have fun
Ian I get the simple green from Bunnings, in the cleaning section. Used to be able to get it in a window cleaning spray bottle but that's not been around for a little while. I get it in a bulk pack at the moment, only about $20.
The finish for the paint is the one you mentioned (cast Alu). Had a look on the VHT distributors website and it looks like its available at all the major car parts places (Auto 1, Repco etc).
Will grab some in the morning. How many cans for the cases? How many coats?
Thanks Ed, I'll go shopping tomorrow. You should get it done with 1 can, but I'd buy 1 for back-up. Just realized the VHT is a sub- brand of PJ1, which I've just used on my 400 in a satin black. It's even better than the VHT, but harder to source :-(
Cheers

Case wear is 'pretty normal' when maintainance hasn't been done and tensioner gets burred so can't adjust.
File off any sharp edges that could fall off in future, dismantle 'horse shoe' part of tensioner, file/grind off the burrs and push pin back in.
'Grooves' don't seem to make any difference when it moves free. (done several over the years)
BTW,if you have a small carbide burr for Dremel, it's not a bad idea to remove some of the casting 'flash' inside case
The swingarm will bottom out on the exhaust bracket on the passenger side before they mount up, they're too long. They also won't clear the chain guard or the sprocket dust cover. They are also non rebuildable. No removable seals.
It worked on my bike but none of those interference points were on mine. No exhaust bracket, chain guard or sprocket cover. I had a different front end. So, in my case, the suspension was in balance.
Muffler bracket has been modified to clear the swingarm as the plan was longer shocks from the beginning so no issues there.
The options I have are Hagons or these. I would prefer new better handling shocks but I also love the look of the reservoir. New with a reservoir is a bit pricey for my budget.
Got me some paint today ready to do the cases and rest of motor. Barrels and head fins will be black, the rest silver.
Waiting on my blast cabinet gloves so I can finish the cleanup.
Here are my switch blocks. The actions on some of the parts are pretty rough. Hoping a good clean will get them working like new. Some of the buttons however are well past it. Can you buy these on their own or am I looking at throwing these in the bin?
Left is not too bad:
Right has damage on all the switches:
Plan was to polish them and repaint letters.
Edit:
Got stuck into the cylinder studs. Double nutting them worked until the last 3. So I bent the studs over hoping to twist them out that way but they are still not moving and I am worried I will fatigue the metal and snap them. Anyone got some pointers for me?
Bending the studs wasn't a good move.
Best bet now is to clean around them as much as possible, apply release oil and heat case.
Allow to cool and do it all over.
Hopefully the heating/cooling will allow release oil to creep down the corrosion
I would straighten them out, double nut and tap on the tops while trying to unscrew them, use a combination wrench on lower nut. (or two so you can keep nuts locked together)
May need couple of tries over a few days, you really don't want to snap or cut them off
rub some hand soap on the case, if it turns brown, your getting too hot.
You'll probably need a drill press to get to the one you snapped off, at least 400 cases are relatively easy to do as they are parallel base/split
BTW, you can full dismantle the switches to polish the alloy
