BSD Performance

BSD Performance THE HOME OF PERFORMANCE TUNING, ECU REPROGRAMMING. BSD Performance has over 20 years experience working directly with Dynojet.

Offering a complete tuning service has always been BSD Performance’s goal and our fully equipped workshop, engine building room and Dyno all play a key part in producing reliable, rideable motorcycles, road or race, that are not only a vast improvement over stock but also live up to expectation. We use a Dynojet 250i Load Control rolling road Dynomometer and the ability it gives, to control engine

rpm at any throttle opening, is crucial for consistency and the precise build of a performance fuelling map. Ironically, the knowledge earned in the pre-fuel injection era, working on the Dyno with CV and flat slide carburettors has proved an invaluable foundation for everything we do with EFI. With regards engine tuning the first thing we do is find out what the customer is using the bike for, and what they actually want to achieve by uprating their engine’s output. Using our experience we then establish the expectations relative to application; road riders and club racers have very different needs and this part of the process is, we feel, one of the most important. Any motor that passes through our engine room is meticulously stripped, cleaned and, after the tuning work cleaned and patiently, methodically rebuilt. We take our time, and we take care.

Definitely not buses...

But we did get two BMW M100R come along on the same day. Both stunning performers made better with BSD ECU remaps. Our favourite of the two went to the tastefully tricked out version. To be honest, though, either of these would look good in our own garages
Talking of remaps, Andy and his faithful dyno are now flat out providing customers of all motorcycle genres with throttle response and rideability that we should get as standard. Blame it on the emissions, sir.
BSD remap and service requirements are heavily booked, and we are working as hard as we can with the usual diligence to ensure minimum down time. Thank you again for your faith in our services.

A quick pit stop in today for this tidy Kawasaki ZX-636R Race build on it's return from the, only slightly warmer, Spanish race tracks! The bike is running a controlled ECU setup by Mectronik and being a freshly built engine for road racing spec needed a full engine run in and health check.

It's second fresh engine being ran in so far this year and just in time for the Northwest! Dan Ingham will be strapped in guiding this around the curbs before hitting the isle of man shortly after. Keep an eye for him in the Next Gen class as this race build is no joke. You'll defiantly be seeing some impressive speed trap times from a measly 600cc bike here.

A whole roster of machines leaving the cave today, and they're not the same beasts that limped in.

This weeks been a proper graft, but everything is leaving here today running as clean and tight as it should. We're extremely passionate (or borderline obsessive) and ensure every machine gets treated like our own, no shortcuts or guesswork, and no half fixes.

Ride safe, enjoy the sunshine, and try not to scare yourself on the way home!

Look and you will find...
Corrosion, dirt and cream-crackered bearings in single-sider Ducati hubs, if they haven't been serviced correctly (see the photos). Early 1200 Multistrada hubs are proving to be very common. If the bearings aren't too far gone they can be replaced, but if severely worn they will take out the hub - and this is a very expensive replacement job.
Putting a smile on our face so far this week was the "Shark." It was a 1584cc (96ci) Twin Cam Harley-Davidson, but now runs a 110ci (1800-ish cc) set up with Mikuni flatslides. Set up on the BSD dyno, she sure does get away pretty smartish. :)

Boat loads arriving daily. Not a bad thing really...
..especially if you're in the market for a stylish, large capacity sports tool, and for the right money. This is the verdict of us all here at BSD. No, seriously!
This is Chinese brand QJMotor's SRK 921 RR. Four cylinders of 119+bhp performance touched with decent components, such as Brembo and Marzocchi, and styled to impress by some of the team behind MV Agusta's latest tackle.
Priced at £8999.00, some might consider it a bargain. Others who wait for second-hand units will definitely score a good deal.
How much longer before the motorcycling world stops saying, Yeah, but it's Chinese?

Something old and something new...
Different ends of the spectrum rocked up today here in Fenlandshire, to make use of the BSD dyno. The Suzuki is a tasty, race-prepped GSX-R750 SRAD, based on the first 39mm carb model. Take a good look at the trick bits that helped take this bike to a Classic TT win in 2023 -- and, hopefully, again this year.

Fire forward 30 years and QJMotor turns up from China with yet another big-capacity naked. Say hello to the SRK 921 -- a 9291cc, 4-cylinder tool that's packing more elelctrickery parts than Bangood and Temu! Ride-by-Wire , Quickshifter , Cruise Control, TCS, Launch Control, 6 axis IMU Cornering ABS, 1080p Dash Cam, plus BlueTooth and more makes it spec-wise on par with anything else out there. Performance isn't bad either (read the road test report in UK bike media soon).

It's holiday weekend. Yay!
We hope the weather holds for everyone to make good their passion for motorcycling.
All the best from us here at BSD

It's compact but does the job.
It's a road-going bike but its primary purpose is to compete in hill climb competitions. This is a Kawasaki W650-SS.
Power is provided by a Kawasaki W650 donk fed by 2 x Amal MkII 34mm carbs, with electrics by Benjy Straw. The frame (T45 tubing) and exhaust were crafted by Jeff Cain at Co-Built. Yamaha R6 forks and YZF125 wheels do their best to absorb any bumps, which is good when you're astride a hardtail frame. There are more details to ogle at and the BSA B50 petrol tank is one of those deets.
We like different.

Scuffed knuckles, sir?
Be assured you will draw claret unless wearing gloves while delving deep into today's motorcycles to access the rocker cover and extract it to get at the valves, let alone change shims. It takes time, too. That's the joys of servicing. Especially when it comes to Kawasaki H2 models and the like. Yes, we are busy. :)

What is a good bike to ride?
One example would be the latest (MY25/26) Kawasaki Z1100 SX series. Comfy, neutral handling and nothing to think about when riding. Now imagine said bike with a BSD ECU remap!
Seriously! It makes a good bike better. No throttle hesitancy or the like, just good old fashioned creamy drive at the twist of the throttle grip.
BSD's dyno guru, Andy, likened the ride (a long test ride) to that of "a well sorted Honda VFR750/800 Honda, in the sense it was just so easy to ride." Having ridden just about every new/modern bike, when Andy mutters that a specific bike makes him feel good it is definitely worth noting. Test ride time, we think.

Classic in the making...
Not quite. That's because this bike, at 36 years of age, is already a classic and undergoing a full resto and upgrade trip by it's latest owner. We've got the job of setting up the carbs to get the old girl running smoothly. This will involve full carburettor strip, replacing tired parts, reset all adjustment to stock, and then dial-in the fuelling to match the exhaust via our rolling road. Now, who of you knows what it is? Complete model designation required. Thank you.
