Best way to go replacing a '01 bottom end

(1/9) > >>

needsatopend:
I just picked up an '01 KX250 L3 that wasn't running. Previous owner said it just needs a top end, but I got the top end off today and found a considerable amount of up-and-down play in the lower con rod bearing. Also seized up pretty bad, so yep it's toast. It also smashed some bottom off the piston when it slammed down after the bearing went, I think.

So what is the method to take in KX-riders experience? Should I have the crank rebuilt and a new con rod installed. OR just go with a whole new bottom end kit like the one offered by Hotrods or Wiseco?

Thanks

I send all mine off to be rebuilt and I use a Wossner rod kit whenever possible.
And I know they make one for your bike as I checked for someone else earlier today  8-)

I put a hotrods crank in my 2000. It looked like a good quality crank to me. Id wager that as long as u use proper install tools and procedures itd be fine. I think a lot of people run into trouble from inproper install more than anything. Ive revved the mortal dogs**t out of mine and its doing fine

How does the price compare to buying a pre-assembled crank?  Do you send yours to Pinsonnault to get rebuilt?

sandblaster:
All my personal stuff goes to Todd but I always get mine balanced so I'll have to get the cost without balancing.
These are retail prices.
If you score a discount on eBay or have a buddy who set's you up, so much the better.
But for the sake of the average guy comparison we will use Retail.
