Have seen plenty of people on here doing their own bottom ends, and there have been some problems here and there. I always outsourced this, but it's not so bad on a bike engine. However, just pressing the crank together can be very hit or miss, and the reason I never bothered. Check out this vid of a 'miss.' Whenever i buy the tools, and do a lower end I will surely take the assembled crank to a shop (likely a kart shop, and not a bike shop) for truing.

Wow. I know that some folks here swear by Wiseco products, particularly for the 220 piston kit. Ever since the early 80's, I have kind of sworn off of Wiseco products because I ran into an issue with a DT175 Wiseco piston. The skirt ports were nowhere near the size of the ports on the OEM piston. The Wiseco had 1/2" diameter holes drilled in the skirt. The OEM piston had large rectangular windows. I also did not like the fact that the Wiseco pistons have to be fully warmed up for them to stop rattling in the bores. Their rings are also much thinner than the OEM parts. They are also not available in A, B, C, D sizes like their OEM counterparts. They are a "one size fits all" piston.
It used to be that a person could save $10-20 by buying a Wiseco piston kit, now it seems to be the other way around.
I am still surprised to see this kind of poor crank quality from Wiseco. They are a reputable company that many people have faith in.

If I'm not mistaken, the Wiseco Cranks that had problems were almost all CR250 replacements. (Can't remember the years it fits)gregp wrote:Wow.

I have heard a lot of people say that they would never use a Wiseco crank in their motor, just because they have heard the story of the CR problems.
I've also heard just as many horror stories about Hot Rods cranks.
I put a Wiseco crank in my KX250. It works great. I wouldn't hesitate to put another one any of my bikes. Ehh....except maybe not if it were a CR250 lol
