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.

If you own a BMW and want a shop that treats your car like their own, Best Motorwerks in Rancho…read moreCucamonga is the place to go! I recently took my F90-gen M5 in for basic maintenance and spark plug replacement and the service was nothing short of exceptional. From start to finish, the team was professional, knowledgeable, and truly passionate about European cars. They handled everything with precision, ensuring my M5 got exactly what it needed. What really set my visit apart was the owner's personal touch toward the end, they even helped me out with a detail going the extra mile to make sure my car looked and felt its best when I drove away. It's rare to find a shop that combines expert-level service with genuine care for their customers but Best Motor Werks does just that. My car is running smoothly and performing flawlessly and I couldn't be happier with the experience. If you want top-tier BMW care with a personal touch this is the place to go!

I've definitely found my go-to mechanic and plan on returning for any future repairs I might need. If you want honest, quality work on your vehicle, this is the place to go!"

Now after spending over 7k on this rebuild job, it leaks oil from the weld and he will not stand behind what he took upon himself to have fixed and make it right.

Wish I could post our conversations and his invoice to show how Anthony is full of lies. BEWARE!!!
