Hey, just wanted to give a quick update on testing.

John Murphy was the first rider to try them out. He installed the grunt manifold and fuel rail the day before Mini O’s down in Florida. He practiced a start to see if he could tell a difference and nearly looped out when he shifted to 3rd gear. That is on a bike that just had an ecu, fmf exhaust, and your parts! I asked him how it ran, and he replied “fast as ****”. He was pleasantly surprised with the results for how simple it was. Out of around 100 250 pro riders, John was 15th in timed qualifying, ran top ten in his heat race (7the place start), but had some bad luck in the main.

Next up I stuck the manifold on Tristan Falls’ new MC250F. In completely stock form, it helped tremendously on tighter tracks. I made this test more “blind” by pulling the bike in a box truck while swapping manifolds without him aware of what I changed. He knew I had purchased a ported cylinder head, and he thought I had installed that between rides. When we did test it with the ported cylinder head, we found that we could get the same bottom end with the manifold as we could with a 2016 intake boot and decked cylinder head. To me, that was great news, because I’d much rather achieve the results with the manifold than have to increase compression, tighten tolerances, and track down older air boots.

On the MC450F in stock form we were all kind of in-impressed with how smooth that bike is. The general consensus was we didn’t care what rpm we achieved it, we just wanted excitement somewhere. The manifold solved that! We’re currently running the manifold, the 9oz clutch weight, and a 14/52 gearing both to stretch the power out and free up the chassis.

When isolating the fuel rail on both 250&450 we couldn’t tell a difference in power, but didn’t experience flame-out like we had on off throttle scenarios with OEM components.

All in all, very pleased! We’d like to order another setup for the 250f.

Ive built my 500exc around most of the products offered by BDSM for 3 years now. I can say my bike is a complete BEAST and have been more than satisfied with the products Dave offers for our toys. It doesn't matter if I'm not in the right gear on climbs, if I input throttle, the bike pulls, hard. Fueling is on point!

Like many others I was very skeptical about the severe improvements the parts would make on my bike. It wasn’t until I watched every one of Dave’s YouTube videos that I gave it a chance. I started off slow with a few pieces and ended up buying nearly everything in the bike bundle if not more. The grunt exhaust manifold was the game changer for my bike as it wouldn’t wheelie easily out of the gate. Once I got that installed and later addressed the fuel related issues, I can’t keep the front end on the ground! Thank you for all your work and I will continue to buy and recommend your parts in the future.

Super happy with the bike’s performance! Even more happy with Dave’s responses, insights and advice. My ultimate compliment is for Dave standing behind his products and great customer service…Highly recommend Best Dual Sport Bikes!

I have used Dave’s parts on several bikes as projects now and would highly recommend the end cap for the exhaust and the injector relocator kit as it gives the TPI more throttle response and power. His fit and finish is absolutely some of the best I have seen. I was skeptical about the clutch weight but it does help with the low end chugg!

I have done several bikes with products from Dave. I have piece marked things in the past but I will tell you his stuff flat out works. The quality of his components is fantastic and the fit and finish is unbelievable.
After dealing with him personally as well I would highly recommend his stuff!!!!!

Installed the fuel package including fuel pump, filter, 90 degree connection, fuel rail
easy to install and works great with no flame outs at all!

Also, installed the Big Oily clutch cover, easy install and looks great! The added oil capacity is a good peace of mind especially on long rides with no oil changes.

Would like to mention that this company ships their products in a very well thought method of packaging to assure a safe arrival.

Thanks Dave for all your videos and expertise, it's been a huge help in producing my awesome KTM 500 !!!

The parts are great, machining is second to none ! I love the fuel filter much larger and more efficient, the fuel rail running straight in instead of two 90degree bends makes a lot of sense. If you put any miles on the pavement you need this wheel weigh, I tried different stick ons and others but this is clean, looks great and functional . The tank fitting is a must have stock one is to vulnerable.
Thanks Barry

Booster plug was an easy add on and does exactly what you said it does. Bike runs great and pulls much better in low rpm zone. Also added the foldable levers they are very nice. I also added a 14 tooth front sprocket. This is definitely a must have. Thanks for making good products at affordable prices

The Coober ecu made such a difference on my 300 paired with an RK Tek head. By far the best running 300 I have ever had which is something I never would have thought possible after I first bought the bike as it had very lack lustre unpredictable power through the bottom and mid. The ecu and head cleaned it right up. It does not sign off with my snow bike kit installed in the winter either. It pulls with the big 4strokes! I also Feel a lot better knowing I have the better fuel pump and filter in my tank on the longer in the middle of nowhere rides. Your videos are fantastic and easy to follow! Keep up the good work it’s appreciated.

Everything worked great for me.His Videos were a huge help as well.

Great quality and fit ,last filter you'll buy just take the screen out clean it with spray on brake cleaner and your riding for a long time without wasting time or money on the stock cheap junk. Every KTM, Husky and Gas Gas owner will be happy with your stuff. I HAD A CLOGGED FUEL FILTER THE OTHER DAY THE STOCK TINY INLINE ONE THATS OUTSIDE THE TANK, IM GLAD I BOUGHT THE FUEL BUNDLE FOR OUTSIDE THE TANK. I DIDNT INSTALL IT YET BUT THE MUCH BIGGER FILTER WILL TAKE YEARS TO CLOG IF EVER. THE 90 DEGREE ELBOW WILL MAKE THE GAS LINE FOLLOW THE BOTTOM OF THE OVERSIZE TANK I ALSO JUST GOT NICELY. THE INJECTION PART WILL GIVE THE BIKE MORE INSTANT THROTTLE RESPONSE. THANKS FOR GOOD INSTALL VIDEOS.

Very impressed with all the components and yes the power increase was excellent along with fuel air ratio, I also installed these products on my 2017 FX 450 with great results, my question is on a cold startup my 17 FE501 bike with vortex ECU will stall after about 20 seconds, once I restart it is fine, bike does this every time on cold start up, I can just about predict when it stalls, like it needs to reset itself?? Does anyone else have this issue?? My Only complaint.
