Must Do Mods for New WR400 F
Posted December 05, 2001 - 11:45 PM
After many months of research, I have made the decision to get a WR400F as opposed to the KTM 400 EXC. Please don't all write and tell me about electric buttons etc... The decision was so close and what made it for me was my son, who is getting his first bike this xmas - a TTR-90 - he was so sweet when he said he wanted to be just like me, that I reasoned that I had to get a Yamaha, rather than force him to learn on one of those bumblebee KTM 50's... So...
Having done so much research, I now feel that i know the WR400 pretty well. I reckon there are some highly desirable mods to be made almost straightaway The way I see it, the mods would be:
Throttle slide - trimmed back.
Exahust restrictor - removed.
Handlebars replaced - this goes along with the next two...
Steering Damper - GPR seesm to be the one to get.
Top Triple Clamp - any suggestions?
What else would you experienced owner recommend... I am not after the ultimate power machine, ... Air box lid?
Of course I plan to have the front and rear suspension retuned to my size - 6'6" and 260lbs I reckon that I would need to move the bars forward and have a higher bend...
Anyone with direct experience of Pivot Pegs - www.eatmydirt.com.au/pivotpegz/ ?
What about clutch baskets?
I will obviously consider a pipe, replacement ignition etc aftetr I get used to the bike, but I want to get the weak/unsuitable/restrictive things out of the way ASAP.
Thanks for your input... Let me know So I can hit the dealer up for some stuff before he forgets he sold me the bike...

well mr dude person.
we don't have grey wire to trim but we also don't have a throttle stop to trim back so you're ok there.
also you have the euro exhaust like me so you can't pull the guts on it.
for the handlebars i'm going to guess that you're broad across the shoulder and that you need flat (as opposed to turned back) bars like me. this on it's own is worth about 3/4" of space.
for the top clamp you'll want one straight away that takes the "fat" or the "protaper" type bars. they cut out all the vibration. the TC should have a range of forward travel to help you. but it sounds like the ability to take a GRP damper will rule over all here.
while you're there you must change the grips which are flimsy and give you wankers cramp later on. mine are apico, the rubber is really thick.
YZ timing is a free mod as long as you have the time.
the BK mod costs tuppence and the jetting can be made cheap by going straight in at the right set up. ok, ok! what i mean is, i spent a lot of money buying the full range. you only need buy a fraction to get it right.
if you look at my jetting you won't be far out.
160,155 and 150MJ
buy 170, 160 MAJ
40, 38 and 35PJ
the pilot air screw
and because you'll need a spare air filter get a white bros etc.
if you fall a lot get bark busters FOR PROTAPERS.
in aus, AND with the jetting right i wouldn't think you need a flywheel weight. but if you find it difficult slogging then get a "juice clutch".
grease everything afor ye go. standard tyres are crap so if you're a pro-change them.
that's it from me. good luck.

If you're 5'6 (like me), you should remove the seat alltogether...

On my WR...
Throttle thingy - gone
Exahust restrictor - gone
Handlebars replaced - personal preference
Steering Damper - none
Top Triple Clamp - stock
Air box lid - gone
move the bars forward - whatever
higher bend - again, whatever
Pivot Pegs - never used 'em
clutch baskets - prob was only on some '98's I believe...
a pipe - stock
ignition - stock
Dude... why is everyone saying dude so much... anyway, you gonna race or what?? Why are you trying to gut the bike before you even get it. I've had my '99 for a year now, its still bone stock minus the throttle stop, airbox lid, and that muffler cork. Hell, I havent even wasted the stock bars yet, and we all know those fold as soon as you lean the bike against a wall. And as far as timing or jetting, yeahright, mine runs perfectly as is. Maybe I just got lucky or maybe someone fixed it already. Either way I havent even opened the carb yet and don't plan on it unless it quits running right. Changes to the timing don't interest me yet either. Now I will admit, to me, stock yamaha forks are harsh. But, suspension is the easiest thing to fix and besides, unless you weigh 155 lbs, you're going in there anyway. Other than that, a saying about fixing what ain't broke comes to mind.
Seriously though, if you wanna spend money on your baby, by all means, have at it. But a new ignition? Why? And the grey wire thing... whatever. You gotta realize most folks on this board are beyond serious when it come to blue bikes. Often they're pushing the edge of whats capable on these bike and while their advice is probably as expert as you'll find, the bike itself, even bone stock, is still way beyond average. I'm no expert desert speed demon, but if you ask me, this bike hauls some serious ass as is. Frankly, mine still scares the crap outta me and I love every minute of it. Maybe one day I'll go searching for mods galore for old blue but ya know what... I doubt it. I still can't find the end of 5th gear. Maybe if I were lucky enough to ride for a living, things would be different.
I've owned a few bikes in my life, ridden even more, and this WR is at the top of the list regardless.
Either way, have fun... DUDE!!!

Obviously the day will come (sooner than I expect) that my son will be lapping me around the backyard track, so I need to have options for that - pipe and YZ timing etc... But until then , I realise this is a lot of bike to come to terms with... Will let you know how I am getting on with it...
