I'm looking, I might collar at them in the AM, to see if they can set me up with 2 identical numbered injectors...
M42U I'm assuming is the style I need, these guys know injectors!

got it, order these and they match 2 and the price is good!!!!

heres the guy that rebuilt, check out his machinery....great experiences with him, but this would be a over winter deal as the bike will be down if I rebuild them....

GREATSOURCETHO GUYS, I had a turbo set pushing 450 at 12psi....he re worked them same power like 5 psi less...nolie.....and I knew how to place them in engine due to each one numbered with all specs possible.....

ill send both injectors, they will come back better than they are now, AND fuel pump for the price of one injector,,,,guess ill start with this plan, wait for Scott see what he says, take it from there, any other BREAK IN TIPS ARE WELCOMED!

Man this is a whole other level I didn't wanna touch, but we've arrived, I've seen the roller style, its obvious the benefits, as far what works with my engine, ill call Scott and see what he recommends as far as that, I'm right there too..lol

 

WOULD these according to flow rates be a tad higher than the stock, and a tad lower than the 5.3's?

fueling 5.3 looks just like roc's? Dif color o-ring, but I know rc can do that....hmmmm

settles that you were right above, gold bike sorry typing, the 4.9 and the throttle body size, and if ur running 55mm thats to much for me, 50-52 MAX, and the 4.9's are they way!!!!! one down!!!!!!

all specs for fueling injectors

When do you need larger injectors?

When you modify the original OEM engine components, i.e. bolt-ons; exhaust, headers, throttle-body, intake, air-intake; turbo kit, supercharger; internals, pistons, camshafts, etc.; any and all aftermarket parts that have the potential to raise the engine's horsepower rating.

When retuning or remapping your engine control unit (ECU) there is a potential for a generous horsepower increase. This is a good time to calculate for higher flow rate fuel injectors.

Through tuning or a pulley upgrade on any engine factory-equipped with a turbo- or super-charger, or installing a larger turbo- or more powerful super-charger, higher flow fuel injectors should be considered as part of this upgrade. More air to the engine necessitates an increase in fuel to maintain desired Air/fuel ratio (AFR).

The fuel injector flow must be matched to the airflow requirements of the engine over the entire rpm operating range.

The injectors must be able to supply a large amount of fuel at wide-open throttle to prevent high rpm lean out, and transitional amounts to cover all of the operating conditions in between. This is why FiveoMotorsport flow-balanced and matched fuel injector sets are so important for overall engine performance.

Through proper tuning and possible upgrades to other components, namely the MAP/MAF in extremely modified engines your tuning-professional will be able to accomplish an OEM-like stoichiometric air/fuel ratio (AFR).

Get it right.

The Fiveomotorsport flow-rate calculator is based on potential and/or actual engine horsepower. Depending on the option you choose, the calculator can be based on wheel horsepower or power to the crankshaft. Because of the variable percentages lost with; front and rear, 4-wheel or all-wheel drive, we can make slight adjustments when needed.

Also note that the our flow-rate calculator assumes a base fuel pressure of 3 Bar (43.5 psi) and a maximum injector duty cycle (IDC) of 80%. This leaves some additional room for boosted performance and keeps us below a 90% maximum threshold.

We use the 3 Bar (43.5 psi) pressure rating and 80% IDC because nearly every OEM and upgrade EFI system in the auto industry also use these factors.

 

I think proof like a tasteful shirtless pic is in order.

Great to have a healthy body image, now let's see this solid man physique.

Lol JK......DONT post any pics please let's stick w motor stuff, which BTW is giving me a migraine. Too much indecision, consult w the experienced builder on ALL components and just relax sit back and enjoy.

 

at the very least what air cleaner do you recommend, ill up the throttle body later, I have the SE , 90 degree like most rockers ,lol....and the vance and Hines big radius dual, I DIDNT KNOW ANY BETTER, looking at the D&d Bobcat 2-1 seems to be the best choice....this will happen asap........ill break in with SE filter and pipes, in the meanwhile I wanna order the DD FATCAT, I forget, the better one,lol, and I see they have Heavy Breathers SE filters, Would Love something to SIGNIFY I HAVE A 107 BUILD, ONLY thing I saw was a fuel Moto deal, but they don't get scotty credit!!!!! Suggestions

 

Dave if it makes you happy, I have PLENTY, from when I was Serving till now...lmk....LOL....yea, I'm all over the ****ing place man, got a jumbo cup of coffee, never mind ENERGY to go, 3-4 hours every day at gym, and I'm going to sleep for MAYBE, 4-hours a night.....mo ****,sucks for me, and I hit the bag 500 times, each arm!!! every night to help fall asleep, doesn't make wife happy, so I took free standing 80lb bag and hung in garage...

 

Just out of curiosity, why are you going to break the motor in then change everything?

Sounds to me like you are buying alot of parts twice.

Might be a good time to pause and get everything in order before you buy anything else.

I have read this thread 3 times and am still trying to figure out which part to try and help on.

My 107 is running 58 mm throttle body.
I would definitely not go any bigger then that.

As for intake, why not stuck with the one you have?

Exhaust.. the big radius aren't the worst in the world. Definitely not the best. When dyno tuning your motor be ready to adjust the length of baffles and wrap on them.

I wouldn't go switching rocker arms now. That's something that should be decided before headwork and cam selection is done.

sometimes too much reading adds to too many options and confusion... all of these choices you are looking at are really gonna affect the rideability more then the overall power numbers.

 

well for example, you say you run 58mm I was told no bigger than 55....this is a THOUGHT AND EXPERIENCE thread, ill seee what everyone does, and works for them, and ill make a educated guess for myself, as for buying parts twice, I paid to have throttle body ported, so naturally I'm gonna use it, with my crappy FP3 that DOES SUPPORT 107/CAMS/INJECTORS.....but NEXT SEASON, over winter after I have some good milage on her, I will go with a better pipe, intake, injectors, etc.....Hope this helps you understand, as I can use all the advise I can get, I am a lil all over the place as I have NO HELP AND NATURALLY IM STRESSED OUT, FOR THAT I APOLOGIZE.....anything you can contribute will be helpful, see I been watching guys here, I know that prodrug guy knows his ****, that Dave w/jason mask knows his ****, I've been reading there posts for a couple years now......so I know who to listen to, ...

 

as for the intake, its a SE eagle, but NOT 58MM SO WHY WOULD I STAY WITH THAT, MAKES ZERO SENSE THERE.......as they have others that will line up with throttle body when I'm ready, if I'm not happy with power, I'm just getting my ducks in a row, and buying stuff lil here n there, I have to STEAL MONEY FROM MYSELF,ive done a shitload more than the 107 build believe that, I have a build thread if your interested...no offense but for someone who said he read three time, you should know I have cams and headwork done, motors built, I'm heat cycling TOMORROW......LOL

SO BEING YOU HAVE THE LARGEST THROTTLE BODY OF ANY OF THE 107'S ON HERE, PLEASE SHARE THE REST OF THE DETAILS OF YOUR BUILD, ID LIKE TO KMOW WHAT COMPONENTS YOUR RUNNING, INTAKE /EXAUST NUMBERS, LIFT ETC, THANKS
