Dmac68 Posted February 21, 2019 Report Posted February 21, 2019 All I bought a banshee that was non running. Had a bad reed. Decided to freshen everything up so I pulled the head/jugs . I found the pistons in it say 9355E on the top then 8963 with 69.45 MM under it in the middle. Also found the rod has a CK158 Hot Rods stamped on it and domes say 71m, 17cc, 2 deg. Does anyone know what kind of setup I have here? Has stage IV trinitycool head, 2 to 1 intake and single Mikuni38-85 on it. What do I have here? Also where can I get new rings/pistons for this ? New gaskets/seals for cool head? I have attached some photos. Thanks in advance for the help! Sent from my iPhone using Tapatalk Sent from my iPhone using Tapatalk Quote
Ayesully810 Posted February 21, 2019 Report Posted February 21, 2019 what cylinders? are these cheetah cylinders? ck 158 is hot rods long rod my guess a 4 mil 70mm bore trinity setup did they even make a 70mm bore no idea post more pics Quote
gusto Posted February 21, 2019 Report Posted February 21, 2019 Good guess Sully. I was thinking the same seeing it looks like Trinity domes. Post a pic of your cylinders Quote
Dmac68 Posted February 21, 2019 Author Report Posted February 21, 2019 They are Trinity Pro TT domes. Looks to have a port job as well l. With Trinity Stage IV cool head. Sent from my iPhone using Tapatalk Quote
gusto Posted February 21, 2019 Report Posted February 21, 2019 Google search on the pistons shows a trinity set up. So what you may have is a resleeved big bore stock cylinders. Depending on the shape of your cylinders you might want to reconsider a new set up. The head and domes are getting harder to find, everyone uses the other style. Quote
gusto Posted February 21, 2019 Report Posted February 21, 2019 Damn what a seal job on the head! if your sleeves are good run some new pistons. I would bet that set up dates back to the 90s. Quote
Dmac68 Posted February 21, 2019 Author Report Posted February 21, 2019 It’s bored to 70mm is what I’m told. My plan is to do new pistons/rings and run it. So is this a 4 mil? And thoughts on if this is a good setup or not ?Sent from my iPhone using Tapatalk Quote
Ayesully810 Posted February 21, 2019 Report Posted February 21, 2019 (edited) looks to be a 70mm sleeve in stock cylinders 4 mil crank look how big the intake widows are compared to stock. what do you mean pulled it apart to freshen it up? did you test compression? it might be perfectly good to run now after fixing the reeds.

SKEETER Posted February 21, 2019 Report Posted February 21, 2019 Bolt a cyl back on and itll be easy to determine the stroke size , if you got a micrometer. Just measure along inside cyl wall, bottom dead center, rotate crank to top dead center, should read 54mm of travel for stock , 58mm for 4mm , etc. Quote
97Screamer Posted February 21, 2019 Report Posted February 21, 2019 Measure like Skeeter says. Most stroker cranks use a 115 rod, no way to know if its 4, 7, 10 or something even more exotic. Also measure your old base gaskets and get the same ones, who knows what gasket it was ported for. Quote
