ryguy27 Posted October 30, 2014 Report Posted October 30, 2014 I am going to be ordering 21 or 22 cc Domes this week for my Banshee. I already have the Tank and plastics off, so I have great access to the Cool Head. Anyone have any videos of the correct way to swap the domes and the dos and dont's. If no video maybe a run down of exactly what I should be doing? My goal is to get the compression down in order to safely run pump Fuel.

Bennett131 Posted October 30, 2014 Report Posted October 30, 2014 Consider ordering new o rings. It's pretty simple to swap the domes out. Quote
trickedcarbine Posted October 30, 2014 Report Posted October 30, 2014 It's pretty easy. Pull the coolant hose off the clutch cover to drain coolant. I do that to get as little coolant in the cylinder as possible.Loosen the coolant hose clamps on front and rear of the head. Pull small vent hose off top of head. Remove 10 nuts. Lift top plate off. Yank the small o rings around each stud so they don't bind up when lifting the shell. Now lift the shell off. Domes may stay in or flop out. Doesn't matter. Discard all O rings. Use clean shop towels to soak any coolant out of the cylinder. Spray the bore with WD-40 so it won't rust. Use clean rags and brake cleaner or laquer thinner to clean the mating surfaces and then begin re assembly. Place the larger o rings in the bottom of the shell. Use a SMALL dab of grease to get them to stick in their grooves. Place the domes in the shell with their O rings. Flip the shell and domes and hold the domes from the top side. Slide it down the studs. Stop at about 1/4" and look to make sure O rings are still seated. Drop the shell and domes down. Insert small O rings over each stud. O ring the top plate and slide it down. Finger tighten the nuts. Some won't do this part, but it helps seal multi cylinder set ups. Loosen the base nuts just a touch. Step torque the 10 nuts in OEM pattern or from inner to outer studs. Tighten up coolant hoses and vent hose. Check squish & compression. Fill with coolant. Check for leaks. Put plugs in it and fire it up. 1 Quote
