Hey man, good job. I think you could go a bit wider with the ports. Sounds healthy. I'm glad you found that expansion pipe. Wish you all the best. I crashed my gas tank frame bike, bent the forks and mag wheels. I'll have to find replacements for cheap.
I have regular stock yd I took air filter off and the bottom cap off exhaust have had no issues on flat I hit 48 mph I use the bike have no pedals just the slight push with foot bike moved fine so all the upgrades I don't waste money on only thing this summer i am going to port . So basically if you're reading this you don't need to upgrade running the air filter off did no type of damage whatsoever 48 on a bicycle that's pretty fast if you need to go faster than all the power to you but I wouldn't waste the money doing it
When I was trying to ask was how do you run a disc brake and a sprocket for the motor on the back I have I'm fixing to build a bike exactly like the frame you have with the body 100 how do you put a disc brake and the drive sprocket for the motor on the back of that frame or anybike ?... Does it take a special hub adapter? I ordered new rims their 6 holes..?...
Hey I just saw your video I have a question how do you run I just break and a sprocket for the motor on a bike I'm getting ready to build one and I'm going to have to figure that out do you have to use a hub adapter any advice would be appreciated
