We had our first mx practice day here in Gundy for the year and I ran it a few times. Ran like a dream. Started first kick and no pinging. Bloody rims have started cracking at the joins again tho, so that's the next thing to replace.

 Rims will crack a mile before they tear and inch, bit of cracking is pretty normal

Thanks mate.  I cant afford new ones at the moment so they will have to be right for a while.

Good to see the big 490 getting a work out and some big air.  Good work and glad you got it running well.

I fitted some YZ450F foot pegs.  You can see why in the photo.

Steg Pegz fitted.

 I just made a template out of tin and took it to bloke who does laser cutting and he cut it and folded it for $80.

 Then I stripped the bike back and another mate tig welded some tags to the frame for me.

Hooking into it now.



The further I get into it, the happier I am with the condition of it all. I split the box last night and the gears are great. All the gear dogs are nearly perfect. Some of the bearings are a little notchy but I was replacing them anyway. Crank is OEM so I will recondition it with oem parts.

I pulled the forks apart tonight and they are pretty good too.

I have put together oem parts list of everything I want and it is about $2,400 if I buy here in Aust. or $1,300 from the U.S. Even with the crap exchange rate. Something I did notice is that there are actually more parts available here in Aust than in the U.S. It may say 'no longer available' on the U.S. Websites but Aust has them in stock.

A brand new FMF system is ordered as well.

This week I have to try and match the silver paint for the swingarm and lower forklegs before I bead blast them. I think I will just take them to my mate who is a panel beater to match it. He also says that he has a special clear coat that's virtually indestructible.

The engine cases will be bead blasted as well. I think I will just use the VHT gloss black on them and the VHT primer and clear coat.

I've nearly got the steering damper sorted, so then the frame can be sand blasted and painted. I think the colour called 'Radical White'.

Doesn't give it a real factory look, but it's what everyone had back in the day.

use a satin etch primer on the cases, pretty tough and looks good.

I went down the dupli-colour path with high temp engine primer, then enamel and finally a flame proof clear coat.

I went with the gloss black, but I'm not happy with it (too shiny).  I think I should have gone semi gloss.

I'm tempted to blast it and re-paint it again.

Its not a good photo but you get the idea.
