I was trying to get my standard exhaust upgraded and Harley wanted to charge me over $2,000 and I was recommended to reach out to Justin. Not only did he do an amazing job but it was a fraction of the cost and he was able to get me a higher quality exhaust. I am excited to have such a knowledgeable and personable mechanic and will be bringing my Harley Street Glide to Justin for everything I need.
I did my research and bought all the parts for the work I wanted done. I was looking for someone to put the parts on and build a tune for the bike. Bassani true duels, Star Racing 3030 cam (torque), fuel moto EZ adjustable pushrods, wood alpha directional roller lifters, S&S lifter guide (stock on a M8 are plastic). Already had a screaming eagle air filter installed. Told Justin my plan and he gave the recommendation for the S&S lifter guides. He gave me a quote and it stuck to it. He also kept me informed of the progress. When he ran into a speed bump in tuning it he picked up the phone and made a call to George Bryce who gave him the answers he needed. On time, in budget. The bike was running a lot cooler too. Had me pulling numbers that'd you'd expect out of two into one exhaust. Want to talk pucker factor, with the traction control on this bike will break traction in every gear, without it the rear end would be all over. There's not V-Twin in south Florida that will beat this. Don't believe me, just ask Justin.
