A guy has a running 421 on his banshee for sale I wanna see if there anything I can look for or Compression test to know for sure it’s a true 421 cub and what they usly go for on price

I Recently bought a Banshee really cheap And went out for a ride 6 miles till I noticed something wasn’t right got down look at the Engine and seen the bottom radiator hose was disconnected and I’m sure it over heated Bad and head gasket is leaking a lil so what’s else should I look for or do 2 see any damage and I’ll like to thanks y’all for ur time and help I don’t get help I’m my area from other banshee owner they hate and always throw me in a different direction making my situation harder

Yeah I did that befor I worked on the carbs the 2nd time no leaks at all and I also Forgot to mention that I have the V force 4 reeds but they told me to run 28mm carbs witch I have on the quad now I have 125 jets and 41 pilot jets and when I drives it feels ok I haul ass from gear 1 to 3 but when take off It has a little hesitant then picks up quick after a and while I’m hualing as soon as I go into 4th gears I hit the Throttle that’s when it starts to feel like it’s going to bogg out

Yeah I did that befor I worked on the carbs the 2nd time no leaks at all

I got it Runs a lot better then before the idle sounds about right but the engine Shakes more then before while it’s running I took it for a few spins to see maybe the plugs need to clear up but nothing it’s still the same and as I drive around I hold clutch to start slow my speed as Im down shifting the idle revés up a lil higher then idle comes down slowly to normal. And thank u I do appreciate for ur help

I Recently removed my boost bottle Insert a new billit intake my stock carbs are set at normal idle at 2-1/2 turns and air is at 1-1/2 turns and the clip to the Needle is placed on the 3rd row from the top so after I installed idle on banshee is to high and take it for a ride and hit the Throttle and bogs out quick but still stays running
