Bought this tool to split the Case on my 05 KX250F. The threads on the tool stripped out and was pretty much useless after that. Spent the extra money thinking i was going to get something i could use for any other engine jobs. Highly bummed, will not recommend to buy. Ended up just using a Snap-On Rubber Mallet to split case. Rubber Mallet was around 20 bucks and is still in my box as a usable tool. Motion Pro I bought for around 190 and didn't even work for me once.
