Good company, fast service and support for their products

Explodes after 100 km. We're waiting for a replacement set, let's see how long it lasts. Installation by a professional engine builder should not be a problem. They stood behind the product and sent me two new kits for free, all back together and everything seems fine. I think the kit was made wrong but this company will fix it.
