How would my bike run with a Broken intake manifold gasket

Postby B0b88 » Tue Feb 19, 2013 12:00 am



I'm a complete novice who took apart the carbs 2x and finally found out my idle jets were completely clogged... Tried removing them with screws and decided not to take an easy out to them... I took the smallest drill it I could buy at an ace hardware and drilled through the gunk and got them cleared... Excitedly I put the carbs back together after cleaning them for the umpteenth time and the bike ran like complete **** really sputtering and wanting to die... No clean high rpms like before I drilled the idle jets out also, one of the intake manifold gaskets was installed wrong and broke :/ I'm now waiting for some ultra blue gasket maker to dry... I'm really hoping I didn't botch the carbs by being impatient and drilling the idle jets out...

Drilling the jets out is never a good idea, the 80-81 models are pressed in and are kinda tough to get out, I have gotten my out with no problems but that's me....Using a easyout is risky business, using a drywall screw is also risky because if the tip of it were to break off it's going to be a real problem then.. Once they are removed I always soak them in carb cleaner over night and then use the finest wire to poke thru the opening being extremely careful not to damage the holes, the cleaner weakens the junk and it comes out ok, some use a small guitar string for this..There are holes on the sides of the jets as well as the center thats why I pull them.. Every one of my holes were clogged, once I cleaned them up the bike idles beautifully.. Hey the 82's and 83 unscrew :shock:

Lol, I'm thinking about buying a set of 82 carbs!!! I'm guessing drilling through the jets made matters worse, fixed the manifold gasket... Gonna take the carbs off tomorrow and go through them one more time to see if I missed something...

Also there is white smoke coming out of the mufflers now that wasn't happening before... I did reset the idle air mixture screws to factory setting.. They were 4 turns out??

My guess is you jets are toast get new ones..old OEM's if you can find them. aftermarket are often not correctly made it's a crap shoot with aftermarket jets. Soak the idle jets in a ATF/acetone 50/50 mix over night then try to remove them. Post here on and on NGW, Saunders site in the wanted section may find your jets.


HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,
