Hello. So, just doing some brainstorming on an idea for a new possibly cheaper way to do a shift kit for a 4-stroke HS 142-F without the jackshaft. I am okay if this doesn't work or if the power lost in the system is too great.
If you reverse the HS engine so that the drive sprocket is on the pedal sprocket side then the rotation of the sprocket is reversed and doesnt work. However, if you place another sprocket on top of the drive sprocket and utilize only part of the drive sprocket you can get the chain to run in the right rotational direction (see picture A).
Now, with my new pocket bike transmission it seem like I can get the drive sprocket and SBP free wheel to match up either with the existing mount holes or drilling new ones. This is what it looks like reverse now (see picture B and C).
Thoughts on this? Would love if Pablo can comment. Just doing some brainstorming.
