  1. Hey guys I've been using the forum for advice for a long time, usually just searching but I've created a weird enough problem for myself I had to make an account and post. I have a 1998 WR400, bought it used and abused. Last season I got her running well enough, drilled the exhaust, and opened up the air box but didn't change anything else. Getting it ready for this season I was getting into it and found that the slide in the stock carb was cracked, and the inside was all gummed up. After a bit of searching it sounded like the consensus was that you can just throw a WR450 carburetor in no problems. So I bought this https://www.ebay.com/itm/Yamaha-WR-400-F-WR400F-Carburetor-Carb-1998-2000-NEW/123166146174?hash=item1cad463e7e:g:hmcAAOSwZKBZJcS1:sc:USPSPriority!93446!US!-1 and popped her in. I blocked off the old hot start hole with some vacuum plugs but I cant get it to start for the life of me. I've tried kicking it a billion times with settings on the fuel screw from about 1/4 to 2, with no success. I did get it to start once at about 1.5 turns, but it died fairly quickly and I couldn't replicate it. I threw a new plug and air filter in as well, but no other changes. Anyone able to point out what stupid thing I'm doing?
  2. Hi all, I am new to the board and this is my first post. I have found a lot of info on the earlier model YZ/WR gear swaps fo get a taller and wider gear ratio in a Yz450. I just bought a 2017 YZ450F and I am converting to a supermoto. I will be riding mainly on the street and would like to get a wider gear ratio. Can you swap gears front he later model (2017ish) WR450’s to the Yz450’s? Or would I have swap the entire transmission? I would like to swap 1st, 4th & 5th ideally. Any info or guidance would be greatly appreciated!
  3. Hey everyone! I have a 2005 Yz250. I recently traded a guy for his 2015 Wr450 front and rear rims so I can have that 18” rear. The front hub has the notches for the speedometer off the Wr. Anyone know what spacer I can run to slip over the notches on the Wr hub to fit the 05’ Yz front axle?
  4. Whats up guys. I am wondering if I should upgrade my Drz400, or just sell ot and get a Wr450? Some background: I have a 2000 Drz400 (kickstart ONLY) that I street legaled. The updrades it needs are: > New clutch pack = ..?(want oem so prob. An arm&leg) > Clutch cable = 14.00 > Steel braided brake line = 43.00 > Rear caliper rebuild kit = 19.00 > Rear brake pads = 16.00 > Carb rebuild kit = 50.00 > Upgraded headlight = ..? (Any suggestions?) > Possibly sumo wheels $145.00 without the clutch pack, headlight, or wheels. I will also need to upgrade or refurb. the rear shock at some point. I am wondering if it is worth going all out with the Drz, or switching to a wr or yz? I like that my bike has the updraded cams and carb already and the reliability factor. I also like the weight and extra power of the wr/yz. I just don't know how long they will last before rebuild and general maintenance vs the Drz. So, what do y'all think? Thanks
  5. Hi everybody!! Finally I bought my WR450f 2004, and I am super happy 🙂 I wanted to have a spare set of tires only for "the road" and yesterday bought a spare set from a YZ250 in good shape. Evrything looks the same.... Here is my question: Will they match? or be exchangeable? WR450 Front 80/100-21 Rear 110/100-18 YZ250 Front 90/100-21 Rear 100/90-19 If they will fit in your opinion, which set of 100% road tires will fit? Thanks a lot
  6. Hi everyone, just picked up a clapped out 2003 wr450f. Busy restoring it but have trouble sourcing a exhaust muffler. Is there a newer model wr450 exhaust (stock/aftermarket) that will fit stock header of 2003. Many thanks
  7. Hi there, I’m hoping to get some help here (Australia). My 08WR450F headlight isn’t working. I have no idea when it comes to wiring . It always worked fine until I changed out the stock switch assembly with a smaller single switch (not a light specific one) and straight away the headlight didn’t work. so I rode it for a while without any headlight and have just put the stock switch assembly back on and it’s still not working. I checked all the connections while stripping the bike down and referbishing/rebuilding after replacing the crankcase and new top end and refurbishing almost the entire bike (that’s another story) anyway so I checked the stator wires while it was apart etc and they look fine.. Any one got any ideas please.
  8. I was riding down a dirt road 70 to 75mph and the rear wheel locked. I was able to go off in a ditch and try to see what the problem was. You can pull the clutch and start it in second gear and start riding but first locked the wheel and killed the bike and I couldn’t get it into neutral either. It will run in 2nd, 3rd, and 4th. Seems to shift fine into each gear. I took the clutch apart and things looked pretty decent. The clutch basket had the ridges in the sides so I will need to replace that. I’m pretty sure that won’t fix the problem but was just tryin to get some input into what could be going on and how easy it would be for me to fix. Everything engine wise seems to be just fine but I’m assuming it’s either something with the clutch or a shift fork or something in the tranny. Any help would be appreciated.
  9. Hi all, Does anyone have any experience with installing stainless steel brake lines for the 2016+ WR450F / 2015+ WR250F? I know that the stainless lines for the rear are identical from the YZ450F, but I can't seem to find any stainless lines for the front brake; I'd assume on the WR the front brake lines are a little bit longer so as to clear the display and headlight. Can anyone help me confirm this? Do these brake lines really change the feel of the brakes? Coming from the orange kool aid crew, one of the things I've really missed from those days are the super grabby brakes. I know I'm not going to be able to completely replicate the feel, but anything would be better than the way the brakes feel now.
