    WR426 seat foam!

    Had the same problem with my 400. Had all the usual recommendations, Stand up more, get fitter etc etc. Being 45 and only riding occasionally didn't help. I peeled the seat cover off, and drilled the rear part of the foam full of 1/2" holes, about an 1 1/2" apart. Stapled the cover back on, and haven't had monkey butt since. It doesn't look any different, but now I can ride all day without having to sit side saddle. Cheers Pete Kiwi Vet

    Intermittent Rough Running WR400

    Ive got a 98 WR400, which I've had from new, only gets 30 hours use a year, so is still in good condition. During the last couple of Enduros, I have noticed that occasionally the engine runs very roughly, Backfiring on deceleration, Severe bogging when the throttle is opened, only under load though. It's fine when revving in neutral. It feels a little like it has water in the Filter, but that is OK. It usually clears after a couple of Kms, and is fine. One time it did it immediately after a big G-Out. I have drained the carb, no change. New Plug, no change. Feels very rich, and then clears itself, and is fine for another hour or so. I have wondered about the Filter screen getting blocked, but seems unlikely. It occurs more often just after starting the engine. Even when warm. I thought possibly the accelerator pump was not working correctly, but that would make it lean, not feel rich, am I right on that? Will pull the carb this weekend, and check everything. Another thing, this is a Euro model in New Zealand, and it came without all the restrictors-grey wire etc that the US models seem to have. Also the accelerator Pump squirt has from new only had approx 0.25 sec duration. This bike runs really strong (except for this intermittent problem) Anybody who can offer some advise would be appreciated. Cheers Pete galpin Kiwi Vet

    $200 Cdn bearing lesson

    I put grease nipples in my 98 WR400. Just drilled between the bearings on each side of the swingarm. One pump of grease after every couple of rides is all it needs. Checked it after 2 years, and it was still like new. Linkage bearings still need regular attention, but at least they are easy to get to.

    Skippy Exhaust Mod.

    Chucky, My 98 Wr (NZ) muffler sounds the same as yours. I cut around the pipe approx 25mm from the end, (around, not right through) The 1" pipe slides out of the inner baffle. You will find a spacer around the 1" pipe where it goes thru the baffle. If you remove the 1" pipe and replace with one that is a snug fit in the baffle, the flow and power is heaps improved. From memory mine was approx 1 1/2". That extra 1/2" gives you double the x sectional area! You will also notice two smaller tubes running back through the baffle, the x section of those adds up to approx 1 1/2" also. Makes you think that it was a restrictor for compliance?. Good luck Pete G

    what kinds of jobs do we all have

    The Business card says "Technical Specialist", mainly looking after the Electronics and Control systems at a Hydro Power Station in New Zealand. You know the main reason they Shot "Lord of the Rings" here. It's because our dollar is crap. New WR = $15,000 NZ Cup of Coffee 70c US

    water pump seal - which way round?

    The lip side of the seal should be facing out. ie (writing inwards). Opposite to the oil seal on the other side of the cover. You may need to polish the shaft if it still leaks. The seal on mine leaked after it got hot one time. And the shaft needed a polish. Cheers Pete

    Stock U.S. spark arrestor(pics)

    My 98 WR in New Zealand has a sealed Arrestor. (I believe they are the same as the Canadian ones) I cut it open approx 1 inch from the end, and welded a larger (32mm ID I think) pipe into the end cap, and welded it all back together. Made a huge difference. Yours may be similar. Cheers

    Help needed for sore butt on long rides

    Thanks Guys, (tho the one with the panties sounds dodgy). I'll try drilling the stock foam, Vaseline, then the EVS shorts. Riding more would be great, but am grateful for the few rides I do get to. Oh to be 20 again when I could ride every weekend. Thanks again. Pete G
  11. Stop laughing, This is serious/sensitive subject. I'm a 43 year old Enduro rider in New Zealand. I won the Vets class last year, so still have some speed. Anyone got some ideas on how to still be comfortable after 4-5 hrs riding/racing. I ride a WR400 (damm hard seat) Main problem is, I only get to ride 1/2 a dozen events a year, so have lost some fitness. Mainly occurs in slow/tight events where I am sitting down lots. I'm not going to talk about what happens when the event is wet. (very nasty :-) I use cycle shorts with chamois lining, but often still end up side saddle at the end of the day. Youre all welcome to have a laugh at my expense, but I would appreciate some ideas. Cheers Pete G WR400, Husky 430CR, PW50

    Easy start methods...(or Blah-ha-ha-ha-ha-ha....)

    My 400 in New Zealand must be cold blooded. From cold in the morning gas on Choke on 6 (yes six) twists on the throttle 4 kicks with decompression on Then ease over TDC 1 kick, and it starts every time. (every time) I find if it coughs and dies just after starting, then it needs more gas. another couple of twists and it willstart and idle real sweet. This goes against everything I have read, but has worked for 3 years?? Pete Galpin New Zealand 98 WR400, Husky CR430

    sporadic compression

    Check under the Valve cover, I've heard of two bikes where the Decompression actuator had burred over where it touchs the valve, and consequently not releasing properly. especially if the decompressor is used with the engine running. My 400 does it occasionaly, especially when it hasn't been used for a while. Tho it clears after a few kicks. Pete Galpin New Zealand WR 400, Husky CR430
