So i just picked up 8 703s from the junk yard. they all look good but i was just wondering if anyone had some advice on cleaning them before i swap them in. TIA.

 

I used carburetor/parts cleaner in qt. can that you can buy at local chinazone,o-really.Let injectors soak at least 24 hr,then use compressed air to clear internal ports.You will need injector electical connector and 12v power to click open.
Love my 703s.Goes like hell in between gas stations...

 

What stew said, but.. make sure you're soaking the business end only, not the electrical end. And pull off the pintles before you soak 'em.. No offence, you prolly knew that, but one never knows Love my new 703's! Smooth idle, noticeably snappier throttle response, and more tire spinnin'! Also, I was a little worried about the o-rings.. I just KNEW they were going to leak, but they didn't. I used the old ones off my original injectors. Just got 'em greasy so they slid on easy.

 

I use Berrymans Chemtool B12 fuel additive. Use it straight and it will strip them clean and what evers left over you can dump in the fuel tank.

 

Do a utube search and you will find a video on cleading them using a syringe and a can of carb cleaner. The syringe allows you to flow the carb cleaner through the injector under pressure.

 

Sounds good guys thanks.

 

Is there a trick to gettin the pintles off? i cant get any off and dont want em to break. Help!

 

I used side cutters to take them off but i had new ones to put on don't think you can reuse the caps

 

Fine needle nose pliers, just put a tooth under each side and pop the caps off. And as long as you don't crack them you can reuse them.
