Well I got a little more done recently.
Put on all my graphics.
Posted Image

I also got some new fuel line. It was a pain to put on, but some soap did the trick.
Posted Image

Re-assembled the engine and washed it.
Posted Image

I then put it in the frame.
Posted Image

Posted Image

I then made a bracket to hold on my rear number plate on the airbox.
Tuned out pretty good.
Posted Image

Posted Image

Welded on the nut ( I suck at welding :( ) and painted it.
Posted Image

Posted Image

I also painted my calipers with caliper paint. Turned out pretty nice, but some brake fluid made the paint not stick on some places.

Thanks! I did a little more work since the last update.

I put on the starter and started to wire. We are just about done the wiring, so I will post up later tonight. :)

Posted Image

Cleaned my chain and lubed it.
Posted Image

My trailtech stator wire started to come loose at the start, so I shrink tubed it and put on a zip tie.
Posted Image

Also put on the wheels.

Did some more. :ride:
Posted Image

Made a Rear signal bracket. It goes onto of the tailight and it bolts on that bolt over the wire. Also remade and heatshrinked all the rear wiring.
Posted Image

Put on the exhaust, stock for now.

Installed my trailtech vapour. Luckily the previous owner had one, but he kept it when selling the bike. ( wich I had no clue) So the hole in the front brake calliper bracket was already drilled to mount the speedometer sensor.

When you get your wheels and front brake, get a new line that routes like the new bikes

It wasn't cheap, it wasn't easy or quick to build. But you have to be happy with the results. You learned a ton and you did it together with your Old Man. I'll tell you right now he is happier with this entire process than you are. He built a bike with his kid when there are a lot of parents that have lost any connection by the time they are 18 or whatever age you are. Now he needs a FI WR450 for himself.

What gearing did you choose. Today was the first time I got to really give mine the stress test since its together as a SM. I am happy with 16/40. It's tall but I don't run out of gears so fast and it keeps me from wheelies which cost a lot of money . Careless driving tickets in New Jersey linger for years.
Nice work, be careful. Get a pipe!

you should cut down that stock exhaust or get an aftermarket one cause not digging the look of it chromed out compared to the rest of the bike being blacked out

He needs to ditch the stock silencer because it makes his bike like a 77 KE100 instead of the high performance 450 race engine he has

Thanks Man! That's so true. I know people who bought brand new bikes, but I rather get to know my bike by building it and spending some time one it.
You were a good help with the clutch cover, thanks again.

Thanks! If you have the time and money, do it! I loved every step of my build.

I will, I'm still not sure, but I'm leaning towards this one. http://www.ebay.ca/i...6-/140656500936

Good choice. Remember that as long as your using a full system you can use one from 2003-2010 yz450/250f and 2003-2013 wr450/250f. On my 08 im using a procircuit ti4 header with a ti gytr 4.1 slip on

I will. Are you sure all exhaust fit? I never heard of that.

Change that to 2003-2009 yz450f and all the wr450f's . The 250s have different diameter headers going into the header but the mufflers will match up depending on header diameter. (sorry about the confusion) But yea. I cant guarantee fitment of EVERY exhaust system but mounting points and where the header meets the muffler should be the same. On my 07 i have a 2003-2005 yz450f procircuit header with a gytr slip on.ImageUploadedByThumper Talk1375325247.752561.jpg ImageUploadedByThumper Talk1375325322.432504.jpg ImageUploadedByThumper Talk1375325342.382948.jpg
