Ducati 848 and Ducati Paul 1000 Smart Fuel Injector Spray Pattern Comparison

Fast Frank Racing (www.fastfrankracing.com) sent two sets of fuel injectors for service. One pair from an 848 Ducati, and the other pair from a Ducati Paul Smart 1000. It was surprising to see the differences in spray patters of the two pairs of injectors. Although the Paul Smart is a bigger displacement V-twin engine, it

How Is This For A “Before – After” Case Study ! 2 Ducati Fuel Injectors, One Injector Seriously Clogged.

Recently D&D Cycles in Pensacola, Florida ( www.danddcycles.com ) sent us a pair of Ducati Monster fuel injectors for ultrasonic cleaning service. Putting the fuel injectors on the ASNU diagnostic machine, it was clear there was a problem with at least one of the injectors. Flow rate of the injector on the left was 1/2

Mix And Match Fuel Injectors To Get Even Flow… For Better Performance.

Recently we serviced some Honda CBR1000 fuel injectors for a customer. They were in pretty good shape overall but even after multiple ultrasonic cleaning cycles, some of the fuel injectors simply flowed different than the majority of fuel injectors. Luckily we had additional injectors on hand we were able to get a more even flow

ProFlow Technologies and Greg Melka Win CCS Roadracing National Championship

Greg Melka, co owner of ProFlow Technologies fuel injector cleaning service company, won his first CCS roadracing national championship at the 2012 CCS Race of Champions. The “winner take all” event is held every year at Daytona International Speedway in Daytona Beach Florida. The ROC is the year end event where the racers are gridded

Buying a Used Set of Fuel Injectors ? Don’t Assume They Flow Evenly or Have Good Spray Patterns

So last week we had a customer with a 2008 GSXR 600 send some fuel injectors he had purchased from Ebay. His bike was running rough and a mechanic had assured him a faulty fuel injector was to blame. Unfortunately neither of them knew about our fuel injector service and he bought another complete set

Changing Fork Springs on a Yamaha R6 with 25mm Ohlins forks. And Don’t Forget to Service Your Fuel Injectors!

For anyone that is track riding regularly, or racing motorcycles, you will at some point need to change for springs to a softer or firmer rate. It is not that difficult to do if you have the drop in cartridge kit like a 25mm Ohlins system. First, loosen the triple clamp fork bolt. Not doing

Air Filter Modification For Easy 2 (or more) Horsepower On The 2006 And Later Yamaha R6

So you want a few extra horsepower up top on your Yamaha R6? The air filter snorkel removal is an easy way to get the engine more air. More air, more power. The 3rd generation Yamaha R6 has a “snorkel” on the intake side that was designed to reduce engine air intake noise. This snorkel

KTM Fuel Injector Issues.. resolved with ProFlow

This is more of a testimonial, but we thought it was an informative article at the same time. Early KTM fuel injectors have many, but very small, spray openings, and seem to be more prone to clogs than other model fuel injectors. Even relatively new KTM dirt bikes have had issues with running rough, and

A Look at Some GSXR1000 Fuel Injector Spray Patterns – Before and After Cleaning

So we got a set of 2005 GSXR1000 fuel injectors in the ProFlow shop the other day for ultrasonic cleaning service. According to the mechanic and shop owner that sent them, the bike did not run horrible, but power seemed to be lower than expected. Sure enough, once on the ASNU machine and the spray patters were visible, a

06-07 vs 08 And Newer R6 Upper Fuel Injectors

Do not make the mistake of mixing upper fuel injectors from the 2006-07 R6, with upper fuel injectors from a 2008 or newer R6. The injectors look exactly the same . The 2006 and 2007 Yamaha R6 looks the same as the 2008 to 2012 R6. It would take a rider or mechanic, who is very familiar with these

KWS Motorsports has used ProFlow for the past 4 years and have never been disappointed with the quality. Getting the injectors cleaned always means we get maximum power and performance from the motors we build. Great customer service and fast turn around … A great dollar value.

I have a Honda NR750 oval piston that had not been started for 7 years. Needless to say, the injectors were clogged and the bike would not start. This engine has 2 injectors per cylinder. for a total of 8. I tagged each injector and shipped them to ProFlow. When Greg tested the injectors before cleaning, the flow patterns were all over the map, and the flow rates wildly different. He took extra effort to ultrasonically clean the ones that were especially badly clogged until he got the flow rates close to each other. They were mailed back within a week, with before and after flow rates and resistance levels checked, and every injector inscribed with the tagged number. They kept me informed at all points along the way about their progress. These are ultra rare injectors as Honda does not make spares for this bike. I would trust ProFlow again with these. Good job, guys!

just wanted to thank you for the injector service. The bike went to the dyno before the work and make 165 with an unsteady fuel flow. After the motor refresh (rings, degree cams, etc.) and injector service, the bike came up to 179 with steady fuel flow. Thanks again, this service is def worth the money!


I just wanted to say thanks to Greg for a very quick turn around on my injectors for our Sea Doo. He was honest and knowledgable about his craft. I have since given his name to a couple of my friends, one of whom owns a cycle repair shop and another who owns watercraft repair store. It runs great!!

They did mine and they squirt nicely.

OK, one week exactly and they are back and ready to install. They left last Tuesday and they are here today. Very nice. I have a form that came back to let me know what they were doing before, and what they do now after the cleaning… It’s a cheap way to know what’s going on in there. – Thank you Greg.

Good folks, good work, good results. From my TLR to my ’88 CRX.

Well worth doing. We had great results with Greg.

Excellent service, recommended.

VRC - WERA Roadracing Forum

They do all the injector service on all my bikes. Very happy with the service they provide. My engine builder/tuner thanks them too!

Your cleaning job fixed all the problems my Viper was experiencing.  It now idles and drive like brand new!! Who would have thought at 28,000 miles that was the problem. But it is a 1997 model GTS so 13 years of light driving adds up.

Kyle Tenbush

My R6 injectors were all within spec, however, my GSX-R injectors were not flowing to optimal specs and I ended up re-tuning that bike after the service.  I was able to gain h.p. over my previous map even after re-mapping on a less expensive race fuel!

Vitamin-E, WERA tech forum

IT WORKED!!!! – In 6 years of shit ass idling/running from that bike, I tried everything: 2 sets of plugs, wires, valve adjustments, throttle body balancing, about 200 gallons of Seafoam, 50,000 searches for vacuum leaks. Nothing worked. I send the injectors to MelkMan at ProFlow. Get them back within a week. Install and presto. Perfect. Now maybe I won’t sell it.  RIGHT THE F@CK ON!!!!!!!!
