Back in 2018 I had ordered a big bore kit, a ported head, and cams from BP racing. I called to…read moreconfirm everything would fit my 2018 yamaha grizzly, they said it would, everything showed up and I brought it into a shop to be assembled, and none of it was for my model year. So I got a hold of them and worked out that I could send in my whole motor and they would custom build it. All within the 90 day return window. We'll a couple months to by so I call them and they couldn't find any of my stuff. Then they find it and say they will start on it. So another couple months go by and I call and the mechanic they had is no longer with the company and the new guy has to find my engine. Don't hear back for another month. Well now covid hits and they say it's going to take a while because they're basically shut down. So I give them 6 months with a little bit of communicating and no progress. Finally covid finishes up and I contact them again and they have no idea what I'm talking about with my engine. So I threaten legal action and we finally get rolling with progress. Turns out the casing was too thin to be made into a big bore. They port out my head and offer to cover custom valves. Another 2 months with no update. I call and after about a week of back and forth I demand the info to contact kimblewhite to get direct updates on my valves. They had no idea what I was talking about. I get this all figured out and turns out the ported head won't work because the valves go too deep into the head. So the head is destroyed. Valves are useless because there +2mm and nothing happens with the cams. By now we are over 24 months my quad was in the shop and I was out over 2 grand on motor parts, and I had to pay for a completely new head, shop fees, insurance for the quad because it was under a loan, and make loan payments the entire 2 years that they basically stole my motor. By now the owner and I are Well acquainted and he's offered a full refund and I just want to cut my losses. Well then they hired this new gm to try and fix the company image. (That's what this new guy is telling me.) And he has the audacity to say I should be thankful I'm getting a refund because we're outside the 90 day window. Just otherworldly incompetence and zero awareness to the situation. He was extremely cocky and said he had my refund check and I just needed to text him my address ai he could send it. I texted him while we were on the phone and asked if he recieved the text. He brushed over it and said he'd send the check right away. I never got that check. But I was having my first child, moving into a new house, and I just had enough of them. Besides the 2 years they stole my parts I paid Well over $10k just to get to know these guys. I can't say enough how nobody should ever purchase from this company.

I'm not usually someone who leaves reviews, but I felt like this one was worth taking the time to…read morewrite. I recently bought a new Yamaha MT-07 from this dealership. Unfortunately, after only about 140 miles, the clutch failed and the bike was no longer rideable. To make matters worse, Yamaha determined the failure was due to "user error" and wanted me to pay around $600 for the repair. The reason I'm writing this review is because of James Grosso and Luis, a dealership manager. James was the salesperson who helped me with the purchase, and he was great from the start. The whole buying experience felt relaxed and straightforward, with no pressure at all. We ended up talking about a lot more than just motorcycles--business, books, life, goals, and all kinds of things. He's the type of person who genuinely cares about people and takes the time to build real relationships. When I called him after the clutch issue came up, he listened, understood why I was frustrated, and immediately started looking into ways to help. After speaking with James, I was put in touch with Luis, a dealership manager. He took the time to review everything and agreed that it didn't make sense for me to be stuck paying for a repair on a brand-new bike with so few miles on it. Even though Yamaha wouldn't cover the repair, Luis stepped up and had the dealership take care of it. That kind of customer service is hard to find these days, and it says a lot about how this dealership treats its customers. Issues can happen with any vehicle or manufacturer. What really matters is how people handle those situations when they come up. James and Luis both went out of their way to help make a frustrating situation right, and because of that, they've earned my trust and future business. Thank you again, James and Luis. I really appreciate everything you did.
