Over the next few days I will be showing the full engine nut and bolt/bearing rebuild on my Yamaha WR450.
Wiseco 478cc piston, selected new gears in the gearbox, and cam timing procedure.
This will include a selection of pictures as to why it needed to be done.
Then to follow will be the rest of the build which includes RTT steering stabilizer, powder coated frame and pimped wheels.
Should be good when its finished........before the end of March...for the VD run in Wales

Right side with partial build up.
Two halves together.
Conrod assembly got replaced as a matter of course.....good job really as fatigue was found.
The reason for the strip,loss of 4th and 5th gears.
And this is what happens to a selector fork when it has gears pushing against it that won`t engage.
oooooo ya fooker than bigend dont look great does it, oil starvation for sure as you said on the phone. You was lucky that the gearbox went first because if the rod had snapped as they do, they normally punch a whole through the cases front and back & ...........................$$$$$$$$$$$$$
you need to get out more ................... anal or what
Just fix the fcuker will you and let's go
You`re just jealous cos the closest you get to a `spanner` is someone who resides in Nantwich...

coming on nicely then chris it will be the best 2003 450 that money can buy
Why? Is he putting a KTM 6 speed box in it?
I loved my WR, but them Yammy 'boxes....... just poo. Thought about getting the dogs undercut a bit to help them engage more positively & last a bit longer, but then had a moment of clarity and just got rid of it.
KTM 2 stroke stuff / XR650R stuff. Stiffy's house of bling
Comming on nicely.
Welded on steering stabilizer post.
Not long to go now.
Chris, your bikes in your house! Jeeze my wife would kill me even if I brought a spanner through the door (hence why none of you lot can visit me..). You lucky bugger.
Will the bike be ready for 4 weeks time then? When are you running it in?
Anyone Fancy a Pre-South-Wales North Wales run?
