Re: My First build, EXCITED, but please help.
You need a new wheel. Take it back and complain, they'll probably give you another.
The motor dropped right in mine with no mods to the mounts. (2 cycle motor)
I had to trim the original chainguard to clear the motor, I trimmed the new chain guard to clear the rear fender and I trimmed the rear fender to clear the motor chain.
It went together easily.
I also took a couple of links out of the chain to get rid of the tensioner.
I think I could do the same install in about 3 hours since I now have experience.
