He is a Canadian vendor. Most of them avoid shipping to the U.S because of customs and the fact that it costs a lot more to ship from CAN to USA, and also takes awhile. There was a kit for sale from BGF on ebay for under $300, but either the price went up or they dont have them anymore. You are right, an engine will last longer with proper maintenance, and the ht engines are cheaper/easier to rebuild, provided that multiple things dont keep going wrong. But when you have a chain here, a mag coil there (or 4 of them on one engine in my case), and various other parts continue needing replaced, at some point it becomes a money pit. The 2 stroke kits also require a lot of time spent maintaining them compared to their 4 stroke counterparts. My first engine ran great for a year. The rings went because I had been using marine oil, but until that engine died the only thing I had to do with it was tighten the head bolts and change flat tires. I had 2 engines after that that didnt last that long. My current engine lasted a year and a half, and blew after I installed a high compression head. Now I realize thats aftermarket and not stock, but I know I can spend a little bit more to build a 4 stroke with high-quality parts that wont break down all the time, and it will also require less maintenance. Maybe I just dont know enough to properly maintain an ht engine to a more reliable degree, but the fact remains with the ht engines that they arent all made exactly the same, they dont all run the same, and they dont all last the same. with a 4 stroke, even if you only perform basic maintenance and dont beat the tar out of it, you have a much better chance of it lasting. And its not because the ht's are made in china that we automatically write them off. Its where they are made (the factories) and who makes them (unskilled laborers). I did enjoy my first kit very much, and I wish I could say that I feel the ht's are as reliable as a 4 stroke. But after going through 4 engines in 3 years, I unfortunately cannot say that I feel that way. The ht kits do start out being economical, and if you get lucky enough to have one last a good while without a lot of problems, thats a dream come true. Its just not the case for me anymore.
