New intake boots still leaking

Bought new intake boots for my 76 900 cleaned intake surface installed them checked for leaks with some carb or break cleaner around the boots still leaking I have used some rtv to seal leaks before just wanted to see if there is other options

Shouldn't have to use anything. Bolts too long?

I agree I used the oem screws that came out

You didn't mention where the leaks were at. In the boots or at the mating surface with the head. There should be no leaks with new boots if installed correctly.

RTV doesn't work real well for plugging leaky boots. I found it was better to just replace the boots but in your case you already did. when I replaced my boots some years back I can't remember if I used fuel proof gasket sealer or not on the mating surfaces.

Hope you find the problem. Tim

I use a smear of V-tech rtv ( the 600 degree stuff ) on both the intake flange and the face of the boot and leave overnight to cure once nipped up.
Peel away any excess from inside and outside the next day and you should be good to go.

Ended up using a very small amount of high temp silicone rtv worked just fine although I should not have had to use anything

Were they brand new or NOS?

They were new from z1parts.com probably reproduction but they did say made in Japan

They shouldn't leak.
