Solarmat72 Posted February 9, 2020 Report Share Posted February 9, 2020 (edited) Hello banshee world, I came to this form to seek some clarification and better understanding of how I should go along with my issue. Long story short I purchased my first banshee ever wanted to try the 2 stoke life and wow what a amazing feeling, The last owner built a 4 mill, it has stock cylinders, head, and porting. He added a spacer for the base gasket to meet the 4 mill requirements. I went riding at the dunes sending it hard and blew a hoes that connects to the head I thought it was a loose hose no big deal. Decided it was time for some upgrades threw new basket, clutch and springs and a pancake bearing. the water pump gear look good the gear was perfect no issues, I purchased over sized rad along with new hoses installed them all no issues, Started the bike and not even 5-10 min the bike was spitting coolant from the top main hose, on a 70 degree day. I clamped down the clamp turned it over started leaking from the lower hose. I went down and checked the hose it was almost ballooned. I popped the rad cap off when the bike was cool it sounded like opening a shook Pepsi bottle. Now I'm stuck with options, do I just replace the head gasket and I should be good to go? or the other option is purchasing a pro designs cool head with 21 or 22 cc domes. If going the cool head route do I have to get the domes cut for a 4mill? or do they come pre-cut? is it possible to not get the domes cut and keep the spacer I already have and just purchase regular domes? I am really not trying to take the engine out because I only took it out for 2 rides! I do plan on rebuilding it maybe couple months from now so I know what exactly Is in my bike. Thank you for any help! Edited February 9, 2020 by Solarmat72 spelled incorrectly Quote Link to comment Share on other sites More sharing options...
SKEETER Posted February 9, 2020 Report Share Posted February 9, 2020 Do yourself a favor, pull cylinders and have reported for 4mm, get rid of spacer, and have builder send you correct head /domes, pistons, gaskets. Be done. 1 1 Quote Link to comment Share on other sites More sharing options...

Be done. If I decide to go that route. Since my shee is a 4 mill I pick the domes I want to run and it would be 22 or 21 cc domes for pump gas pro designs and get them cut correct it’s not plug and play situation with the domes they need to be cut for the extra squish?
