have a hotrod crank in my 250 and the main bearing just went bad. the quality of these cranks seems like crap to me, i mean worn out spline, bearings, rod bearing has a little play in it, and even the thread that holds the flywheel on is worn (not cross threaded, just worn). no idea how long this crank was in the bike but still. sorry for the rant.

"made in china" oh ok that explains alot. now that has me wondering though are wiseco pistons poorly made? and is there any other forged pistons that arnt made in china?
-
if im not mistaken , pistons are made in the US

Pistons are still here in USA.... their Pistons are GOOD stuff

Appreciate the video.
I guess getting a factory crank is the only way to go if yours is junk.
I have bought some other equipment from China and have never been real happy with the overall quality.
I have had several offers over the years to farm out some of my business to other countries.
I always respond the same.

I certainly prefer OEM components, but have used Wiseco and Hotrods many times in the past without any issues. That video has been floating around a long time and scares everyone when they see it.

well at least i dont have to worry about a bad crank from weisco because they dont make it for my year

was looking on bikebandit at a oem crank and they have listed "CRANKSHAFT-COMP" now would that be already assembled or would i need to get a shop to put it together for me? also was looking at madmans site and he has listed a crank for my bike for $227, idk if hes just redistributes wiseco stuff but gave him a email none the less

I have used Hotrod rods in my last two bottom end rebuilds with no issues. I pour straight 2stroke oil on the main and small end bearings during assembly
what oil gas ratio do you run??
How many hours were on the bottom end?
Was the main bearing lubed during assembly?
Was it installed by a qualified mechanic??
all of these are ?? you need to consider before bashing. if the rod is straight then what's the problem, bearings wear, and it could be that your crank bearings weren't replace when the crank was rebuilt.
