The GC160 is an upright motor that may be a good candidate for a bicycle.
Yes the GC160 might be a very good engine for the bikes, and thank you for understanding my points, I was not trying to come across as hostile to anyone at all, I just thought there were a few things to be considered on the overhead valve engines that might cause an issue when or if they were mounted at to much of an angle, I could be completely wrong in my thinking on this but knowing these engines pretty well is why I posted the points I have on them being mounted at what could possibly be to great of an angle.
I hope if someone comes across one of them that is working great at such a severe angle, they will post that information with some pics so we can know for sure whta the answer is to these questions I have on the topic.
Thanks for the input here msrfan, matbe we will all know the answer on this for sure in the near future.
