Is there an upgraded CAM CHAIN? This is going to be my next swap.

I don't think so. There is an aftermarket that claims to be better than stock, but I couldn't read anything positive about them. So, when I rebuilt mine, I just went with a stock one.

Does anyone know if 130/90/18 Dunlap 606 will fit on the WR400F?

You might need a bigger luggage rack and a few extra bungees

I've read elsewhere that they do, but I don't have any direct knowledge of it.

My exhaust timing was slightly retarded. I have corrected that problem, and the bike starts much easier, but now I have this problem.

Does WR400F's lights run on AC or DC power?

Are you going to replace the headlight with those LED units?

I have a plan to go all LED so I don't have to rewind the stator. So far so good. I just have to deal with the whole AC to DC thing. The new generation LEDs are really bright and draw so little electricity they truly amazing.

Thumb Lot of info for you on this model bike

I have a yz 426 and I have re-built it about four or five times There is no much I havent broken or replaced on these things over the last few years so I can help any time if your in trouble check out the following links

http://www.advrider.com/forums/showthread.php?t=640587

go to post number 5 this will make starting and low end throttle response awsome but you may have to change to an 01 zy 426 carb because the linkage system on the earlier wr 400's is a little different there are heaps of these older kehin carbs on ebay in the states I got one for another bike for less then $100 bucks shipped to australia and the shipping is usually around the $35 mark

http://www.advrider.com/forums/showthread.php?t=632305&page=4

I am about to put a wr gearbox into my yz and this will make out bikes very similar except for the 400cc Vs 426cc.

There are a heap of guys putting DC lighting systems on the AC bikes so they can run HID lights for some of the 24Hour enduros down here and they work a treat ony problem is you cant go crazy on loading them up power wise they working realy well and quite reliable. I have a spare stator which I am planning to do the same mod to as well you have to change the reg and add a battery or capacitor have had to much on the go to look at this job though.

Shims! never take what they say they are for granted its a bit easier for us cos were metric and the numbers on the shim's are metric but for you guys who have to do a conversion on the number's forget it just buy a hot cams pack and measure everthing in metric or imperial I know of a few guys who have got their conversions wrong and had bikes worse than when they started. ie mic the shim and gauge the gap in the bucket and cam and work it out.


Here is a picture of my rally setup 11 litres on the back and 13 on the front looks a bit funny but it tracks really well and screams in the desert.

Gearing
I was running a 15 fron 45 rear and this proved too much for the poor fifth gear and it finally gave up this was too much. I will experiment with the new wr gearbox and let you know how I go

I love this bike and have considered dropping it down to a 400 but it means a new crank, rod, barrel, piston and I have only got 53 hours on all of these brand new items so mabey in the future. Next time it blows up in a horiffic manner like last time. (120kph and valves broke off while on rev limiter)

Dont give up on the old girl they are good bikes
Cheers

yamahaman, i have been following your build -- impressive.. made me want to look for XT350 to do something similar -- but then I am reminded how much I love this beast. It's been sitting in the garage for months; so I felt sorry for it and went to kick it.. It did not start on several kicks, until I realized I forgot to turn on the fuel. (I drain my carb before storage).

She fired on the first slap. :blush
