This is a little off the ex motor questions but I hope that someone can help with this problem. A buddy of mine got a 375 kit installed in his Rancher and something is not right. The kit includes new piston, sleeve, cam and all the gaskets and hardware to put it back together. It took six months to get his motor back from the guy that installed it for him.
Here is the problem: it has no power, it only has a little more real low grunt on the very bottom. It is slower going down the road than a stock one. The only thing that seems to be right is that it revs out faster, which is the cam doing its job. All that was done was installing the new sleeve and cam. Then of course rejetting it. We have changed the jet about 4 times now. We started out way too rich and now are back to a stock jetting, which to me does not sound right.
I don't know if it is a timing issue or not since it starts fine.
Any ideas? we are pulling our hair out on this one and it may turn me in to a bigger beer drinker. Any help is greatly appreciated.
Thanks
