I need some quick help. I got some 440cc RC Injectors but those SOB didnt come with O-Rings. Just wondering if I could use the stock ones (which are a TAD bit big and harder to push in)?

I was thinking of grinding the inside of the stock fuel injector o-rings out, so it'd fit a tad better... any thoughts? Anyone done this?

 

I bored out stock honda injector seals. have yet to prove if they leak or not though.

 

Thanks I might just do that.
