lt500r hole in intake.

mentally_ill_lt250r · #1 (**permalink**) 11-23-2006

i was wondering if anyone knew why someone had drilled a hole in the side of a 87 zilla intake, the last owner welded the hole shut but im not sure why it was there in the first place. any insight would be nice.

I have seen holes on some of my tecate3 cylinders, some had them, some didnt. The ones I had were tapped for some sort of fitting. I always thought maybe they used it to prime the engine, or power a fuel pump?

no idea. somewhere i've seen things about people using a brass fitting for nitrous but im probably wrong.

i'd say it's for a fogger nozzel they are 16th npt (about a 5/16 hole)

hmm, im gonna guess and say someone got a little wild while porting and made the wall too thin!!!!????

cylinder isnt ported at all, atleast not on intake or the exhaust side, no idea on transfers. it was a hole that was actually drilled

NOS is my guess

The best resaons for a hole in the intake is for a nitrous fogger or a powerjet for alchol.

doesnt seem like anyone ran alcohol, the head wasnt decked until after got it it and even then we only decked it 10 thou to make sure it was flat. thanks for the opinions

If it were for nitrous, It would be in a different spot. I am still thinkin fuel pump.
