    Junk!
  

*by C***A on Reviewed in the United States 🇺🇸 on September 11, 2021*

I bought this kit to rebuild my sons Honda. We did an extensive break in period, followed all the recommendations. He didn’t even burn 1 tank of gas and the bike was smoking again. When I contacted the company they didn’t back their product.
