Here's my tip. While there is no such thing as too bright a headlight, do not forget your taillight! Those are important. A brake light can also be as simple as a second light in the same housing, on a momentary switch. Make sure folks from behind can see you, or they might be the ones to run you over.

My experience thus far;

1. Carb jet fell into reservoir bowl, bike wouldn't run without choke. Open that, tighten it down

2. Pinion gear (small gear next to big gear) flat head bolt came loose and chewed up woodruff key, installed a crush washer and used impact drill to mount it

3. Throttle got stuck wide open because bracket to intake was too tight, loosened that and all is well

4. Bolts on the head, one was missing a washer so added that and tightened back down

That's all so far, it's always something, I'm sure I'll be posting again soon.

Shout out to all the people on here, I really appreciate all your help

There are a lot of pages to this thread, so apologies if this has been covered. I have had too many failures with the chain tensioner, and one of them happened at high speed and locked my rear wheel up resulting in a long skid and instant increase in blood pressure. Fortunately I stayed upright and didn't crash and burn. I built this to ride safely and not die due to an equipment malfunction. I bought an extra master and half link and adjusted the chain length that way allowing me to completely remove the tensioner. I have had no problems at all with this set up. The tensioner that comes with the kit is worthless, and a spring loaded tensioner was not much better. Do yourself a solid and don't use one at all, just add or remove links until it is tensioned properly.

one can also add 1/4in spacers to rear motor mount, but I'm satisfied with the standard tensioner

what i did eventually was get a bar aprox 20" length. drill holes and slot to match tensioner. bolt to tensioner and secure to bar just under seat(drill hole and put another
nut and bolts for further adjustments under seat).
