Oil in injector housing? - ZR-1 Net Registry Forums

Easy on the Mr.!

I wasn't able to get to a set of 90, 1st design injector housings to measure the washer/baffle hole diameter. However, I did measure the hole diameter in the cylinder heads for 91-95 models, at 7/32" drill. If your's are already drilled @ 1/4", i wouldn't re-do them, but i sure would not go any bigger.

If 7/32" is good for the 91~95, it should be good for the baffle washer too.

How about a photo or two of your fix in progress & the end result for "Mr" Dynomite & me?
