Ordered!! got loads of things coming this week. feels like christmas

Ok, well i guess the jetting is one more potential problem off the list: http://www.ebay.co.uk/itm/RFX-BLUE-keihin-FCR-CARBURETTOR-FUEL-MIXTURE-SCREW-YAMAHA-WRF-400-WR400F-99-12-/171251491260?pt=UK_Motorcycle_Parts&hash=item27df6261bc That what your talking about?

Quick question, Do these jettings sound right? airbox lid drilled, stock pipe (but has been cut down) jetting pilot 45 idle air 79 (maybe general) main jet 180

That's all the reasoning I need to order Wiseco. Love free stickers!! Head bearing attempt no 2 on Thursday/Friday. Should have a few more goodies arrive this week too.

3 sets of wiseco valves for the price of 1 single valve from yamaha. It's stupid. Wheels next on my list then valves then mot time. Just need to check indicators/lights all work. Not long now. I'll buy bling bits for summer

Finally got my forks done. Both have been bled fully and feel great. However I tried undoing the top nut and this happened. ... so new tools then re-attempt the top nut

ouch... my local yam dealer want £160 per valve. looks like ill be buying these and paying import duty http://www.ebay.co.uk/itm/Wiseco-Valve-Valves-YZ400F-WR400F-YZ426F-YZ400-WR400-YZ-WR-400F-400-F-426F-426-/191122503805?pt=Motorcycles_Parts_Accessories&hash=item2c7fc9f87d

Well i took my forks out and took the bits up to my friends in Bromsgrove. Bench laid out ready to work: Top of the forks out: Springs and rebound rods out: New seals on: However, the new dust seals just would not fit, so we will be tackling them Saturday afternoon hopefully along with my head bearings. On another note, my water pump seals came so i will be tackling that soon too: FYI i used this guide to rebuild the forks with the new seals: http://www.dirtbikeworld.net/forum/showthread.php?t=16751 Ordering valves Friday (oem yamaha) so thats my next job. Hopefully i dont need to order new shims, guess well see. Next update should hopefully have the bike together again :-)

Right so today i had 15 minutes free so i started by taking the forks out of the frame ready to do the fork oil seals and dust shields: Got the brake caliper off and secured out of the way (looks like she needs a clean/new pads): Wheel out: Forks fully out, ready for seals to be done: Bike's a bit wobbly in the garage now but i should hopefully get the fork seals done soon :-) Thanks Ross.

Why did I not think of this???? Thanks again..Appreciate your input. At the moment I think ill buy valves and exhaust cam. Then when I can afford it buy the intake cam. Still lots to do

What did you blank the decomp hole with on the head??

Thanks dude. A linked video shows how to install etc too and it kicks in 1 kick. Definitely worth the upgrade! No uk suppliers so import tax here I come. Still cant find out if I can just buy an exhaust cam. Rather than the set

Forgot to ask. Can I just get the exhaust hot cam? Or do i need both?

Suppose I could sell the 450 cams to part fund the hot cams. Sort of hp are we talking with them installed? I still have no idea how hard shes going to pull standard let alone opened up a bit. Should be exciting! so it keeps the 1 valve open so its easier to kick but allows the bike to start? Is this the setup you have?

Ti valves would be ideal but I really cant justify the costs right now. But definitely will be upgraded in the future (along with the fc mx carb) Hmmm I wasnt sure on the difference from the 450 cams and the hot cams. Im guessing you can run yz timimg with those as they dont have the decomp?

I can pick up some wiseco valves for 50 quid. Is that kit worth the 200 dollars + tax + handling fees? Compared to swapping the cheaper valves more often? Or shall I stick to oem and just replace often? Sidenote: got the kick start technique about 50% just hard having no decomp bracket so im having to pull on the whole cable. Thanks Ross

First thing before shes ridden is replace valves/springs. But can't find a uk supplier of titanium ones. So may have to go steel. Also im replacing the water pump seals whilst the engines drained and going to check clutch condition. Its getting a full checkup before I mot her. Dont want to risk downtime over summer lol

Vids on the previous post. Looks like an image of the bike side on. Thankz dt. Im 14 stone so will need to do some maths.ive got the full fork manual so I should be ok. Excited to be finally getting there Ross

Hahaa yeah the list keeps on growing..will be nice to have her fully sorted. Anyways here the video

Hi guys, Just an update to say..SHE LIVES!! My friends Ian and Steve came over to help with the swap (i say help, they pretty much did it all) Here she sits before we took the bottom end out: Got the old bottom end fully removed: New Plug: Feeler guage out: New engine in: Subframe off to clean air filter box and air filter (helped get carb in too): Here she sits, all plumbed in (however there were a few ports on the carb that didnt have any hoses any ideas?) Heres a video of her running (took about 40 kicks), my legs actually aching now. found out it didnt need the choke on to start and kicked after the 2nd full kick. After that shed go on 1st or 2nd kick: VIDEO STILL UPLOADING - no air filter used during this run. Turns out the water pump has a little hole in the bottom (as by design) but it was weaping a little coolant, so ill be replacing the water pump seals. Also, Found the top of a valve which was obviously what caused the original motor death: Will update with video's/more pictures shortly Items remaining: Clutch cable Throttle cables Pump seals fit head bearings fit fork seals replace valves push bike speedo supermoto wheels chain and sprockets Oh and i need a decomp bracket if anyones got one? or can find one anywhere? Ross.

Ahhh perfect, thanks DT. The idea is to maybe try a bit of stunting on the SM wheels (wheelies will be happening for sure), but then have stock gearing for the offroad wheels. So ill just swap chain and wheels over when i need to. thanks for the link!. Wednesday's definately a go, so engine will be checked out, clean my carb, clean my air filter. Once shes running nice ill start looking into swapping the cams over (ive got YZF450 sat in a spares box) and other potential tuning routes. got to save a few months for wheels, but what the point in having nice shiny road wheels if the bikes not running hey....

Need to order sprockets/Chain at some point, Can anyone recommend the best gearing? i may pop onto the motorway when the bikes used, but for 1 junction max so top speed isnt too much of a worry. Thanks Ross.

Also lapping the valves. Any input?
