Well, some will tell you they love them, some will tell you they do not.

I am sort of in the middle. The only one I had was a .75 that was on a Tiger 60. It performed well, but leaked fuel quite a bit. But, in spite of that, it always ran well.

For the price, well, it's less than an OS, but no where near an OS in overal quality and performance. The OS .75 AX is a strong solid engine.. I have two of them. I also have three OS 1.20 AX engines and they are supurb.
