250-500cc RIP Husky WR250

pics attached

this was just before it died (ran perfectly)

Ouch!
Bad luck Anthony

 

[franhoser]

wtf, sorry dude. didn't you just do a top end on that bike recently?

 

[Croc]

Gees Ant, I would sell that bike you just don't seem to have any luck with it. Some bikes are just lemons & should be put down. Go trade it in on a WR300, you will be a lot more happier, mine has been flawless so far

 

[Dirtdame]

Looks almost as though a ring got snagged in a port there.

 

[HuskyDude]

Bad news for sure. Hope you don't break the bank try'n to fix it.

Hey I watch your vid. Pretty cool. I saw something near the end that caught my eye. I seem to see this more often while riding these days...

Some day I'll have to stop to investigate these orange things just lay'n on the side of the trail...

 

[Anthony_1978]

great observation HuskyDude!
I ended up borrowing a WR450F of a mate for the afternoon session
There's heaps more carnage but this was the best crash

I need a new cylinder or get mine plated
not cheap $600AU to re-plate

So it can't be bored or re-sleeved? What year model is this bike?

[buzuki]

unlucky there mate.

maybe something wasnt fitted quite right?

 

[husky bom]

looks to me that the gudgeon pin c,clip not in right only IMO

 

[wr 300]

looks like old mate had to finish the race

 

[ohmygewd]

Man thats bad luck Anth? Curious, you didn't play around with the power valve setting as a mate of mine had something similiar happen after his 360 ring nipped the valve.
Take to Electrosil and they'll replate the bore good as new...whilst your at it, get them to order in a new piston and ring to suit the bore size.

I dont know if the wr250 uses a similar design as the wr300 piston, but the Vertex (OEM) piston for the 300 is suspect at best. The ring gaps are not staggered to minimize compression loss and both ring gaps drag directly over the exhaust port every revolution. Very bad design IMO.

I wish Wiseco or Wossner would make a proper piston for this bike cause the OEM piston scares me!

these motors usual are hammers in reliability. Adam is on his third piston and some 7000 plus hard miles and the cylinder looks new. This motor has been around a long time and is known for it's reliability.

Why did you open it up to begin with? And it broke after you worked on it? How did you break it in and what is UR oil mixing ratio?

My motor has been rock solid too, but I'm still worried about the ring gaps scraping across the exhaust port 7,000 times a minute. Questionable engineering from Vertex IMO.

Adam uses Weisco as do most WR250 guys. Staggered rings.

Kelly needs to have someone make a run of forged dome top wr300 pistons
