Yes. Most impressive! The occasional stalling out when cold on take off no longer happens. Much smoother overall with a little more 'umphh' in the low to mid ranges. Best bang for the buck out there, and dyno verified. What's not to like.

Yes, I did notice a performance increase with all the BDSB products installed. The muffler end cap was the first BDSB mod installed to a stock bike, except for a JD Jetting Fuel Programmer. Performance and sound were an immediate improvement. The BDSB fuel rail made the bike more responsive. The BDSB big bottom kit was felt at higher speeds in 2nd, 3rd, and 4th, when throttle is hit hard. The bike is uncorked with intake reeds removed & JD Jetting Fuel Programmer. The imprecise chatter from the clones on the web says “snake oil!” The products work for me and I would not purchase them if the products did not work. The products work!

When I bought my 500EXC in 2018 I had just gotten off of a 2014 350EXC and I was expecting an order of magnitude difference in power. Well, that was hardly the case. Shiny and new, sure, but I was... quite disappointed. I installed the full fuel programmer kit (rails, end cap, manifold) within a month and 4.5 years later it's still be best upgrade I've ever done on a bike. The 500 is a beast uncorked, but most programmers don't come close in sophistication. I ride the bike daily at an altitude of 7000ft, often going up as high as 10k and it roars. Not a crack or pop anywhere, neither lean nor rich, just right. After all this time, at 12,000 miles it's as strong as ever. The kit has more than proven itself in power and reliability. Definitely putting one on my next KTM.

I originally installed both fuel injectors in the relocation block. Stock ECU map. FMF 2.1 Turbine Core silencer. But found the engine to be bogging at low revs riding single track. So I asked for the kit to put one injector back at the cylinder. Oh my...what a great difference. No more bogging and the throttle is so crisp all over the rev range. I use AMSOIL Interceptor oil and I add 2 ounces to 10 litres/2.5 USG of gas as BDSB suggests. FYI my oil pump still puts out 5.6 ml after 137 hrs.

I trust their recommendations and videos. Performance is always spit on! I think the only part I don't have is the new heavy duty oil plug magnet, that will be next.

In late 2021, I purchased a 2022 KTM 300 XC. Prior to that, I had a 2017 KTM 300 XC with an earlier model Lectron carb on it. I have been a tuner for over 50 years. I was not happy with the fueling on my 17 and hoped the fuel injection would be spot on. It was not! I did some research and found PIN IT RACING. The more I read the more I realize that this guy knows tuning. I purchased their injector re-location kit and installed it. It was much better, but not perfect. After talking with Dave, he recommended reprogramming the ECU. This was the exact magic that I was looking for. It not only changed the fueling, but also the ignition timing. The power delivery was the best I have ever felt on a 2 stroke. Hard hitting, but also smooth at the same time. Thank you PIN IT RACING!

We have purchased several different products from PIN IT RACING, from exhaust “Grunt Flanges”, fuel pressure regulators, fuel filters both in line and in tank. Everything we have purchased has worked better than expected.

Side Note: My son just purchased a 2023 Husky 300 FX. We went on our first single track ride of the season. It was pretty challenging. We did not swap bikes on that ride, but he did ride mine after we got home. His comment was that he was glad he did not ride mine on the ride, because he would have been disappointed in his new bike. We are ordering upgrades for his bike from PIN IT RACING!

I got out and ripped it today on two identical southern california loops , here’s what I found.
The Coober and Pin It are both real good but I give the nod to Pin It

The Coober stutters just a tad at even cruising throttle and it hesitates just a tad when I’m blipping it through whoops or hitting jumps coming out of corners on trail.
The idle is decent.
The Coober pulls harder at wide open higher rpm’s.

The Pin It idles better , lugs better down low , has no stutter or hesitation anywhere. It just runs fantastic.
Dare I say my bike runs perfect with that ecu.
Not to mention the price is way better.

I’m totally willing to send you my Coober so you can test it against Yours.
I would love to see that video and results.

Thanks Dave !

It is a dramatic difference! I was shifting around 4000rpm and carrying a gear or two higher than I had before, using 6th frequently now. The sound is slightly louder with a bit more vibration but it easily cruises at 80mph without feeling that its near top speed. I have not opened the throttle fully as there is no need, prior to the tuner I frequently hit the throttle stops. Mixed gravel road, back road and highway have returned 72mpg.

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.
