Exhaust port and intake boot size

[sam0840]

Can anyone tell me what the size of the exhaust port and intake boot hole is. GOing to make a leak tester and I am wanting to use an expanding plug for the exhaust and also need the right size for intake fitting. Quads is stored at my buddies house 25 miles away so I dont feel like driving all the way out there just for that hahaha. Thanks in advance!

I think the inside diameter of the intake boot was 1 1/4". Just use a peice of rubber and your flange for the exhaust.

yea 1 1/4'' i used expandable freeze plugs to make mine, it works on intake and exhaust side just get a nipple to screw into the one for the intake side so it seals, and a low pressure gauge, it works just like a 200 dol one you can buy.
