Thank you for the info ! What do you mean by 9 range plug ? Do you have a part number you would recommend ? Also what fuel ratio / mix would you suggest trying ? I will look up the test and get that done soon ! Sent from my iPhone using Tapatalk

91 octane and yes it’s a trinity cool head with trinity domes. how do I perform the squish test with the engine on the bike ? Sent from my iPhone using Tapatalk

I pulled the stator cover off but you can’t really see the timing plate very well. Do I need to pull the flywheel ? Sent from my iPhone using Tapatalk

I do not. Is there a way I can check that ? Sent from my iPhone using Tapatalk

Thank you ! It’s a 2 into 1 carb setup and I am just running normal fuel with Klotz . What are your recommendations for this setup fuel mix wise ? Sent from my iPhone using Tapatalk

What could be causing that ? Sent from my iPhone using Tapatalk

Compression wise ? I also noticed the spark plugs bad out when riding. The left is worse than the right . Would that be related ? Sent from my iPhone using Tapatalk

Okay I got another compression gauge and it was a huge difference the photos are attached. I also forgot to add I have black fluid coming from the exhaust. Raw fuel/oil I’m guessing ? Sent from my iPhone using Tapatalk

I believe it was fuel but not positive Sent from my iPhone using Tapatalk

I had that gauge laying around and figured I probably shouldn’t trust it. I will get a better one tomorrow and check again. I did notice the left hand side cylinder looked wet vs. right side being dry when I checking this stuff. What could be causing that? Head gasket leak ? Sent from my iPhone using Tapatalk

Okay I took measurements and compression. I believe it is stock stroke. I measured a few times and all measurements were not exact but close to 54.00 mm . The compression photos are attached. I know this is low but what could be the issue? The bike has maybe 2 hours of run time on the fresh cylinders/pistons/rings. Sent from my iPhone using Tapatalk

What spark plug tester would you guys recommend ? Also how do I take the measurement ? Do I stick something down the hole and measure top dead center and at bottom ? Sent from my iPhone using Tapatalk

Guys I have not checked compression. What is the best way to get an accurate reading ? Use a gauge and just kick it over ? Also is there a good way to find out what stroke the crank is without pulling it apart ? I never had the bottom end apart . Thanks for all the support! Sent from my iPhone using Tapatalk

It has a trinity IV head on it (17 mm domes ). It was bored to 69.45 when I took it apart and is now at 70mm. The porting was like this when I got it and has hot rods (CKJ158). I am not sure if it’s a stock crank or not. All I did was a top end and put it back together so any help/suggestions on what I have or if I need to change something or run a race fuel would be greatly appreciated . Attached a few photos of the parts /porting Sent from my iPhone using Tapatalk

Squish ? Sent from my iPhone using Tapatalk

Hey guys I have a 1996 banshee. According to the info I provided on here it was a 421 trinity . I pulled and had to have the cylinders done. It now is bored to 70mm and has 17cc domes that we’re originally in it . What type of fuel should I run with this setup and can I order it online some place ? Sent from my iPhone using Tapatalk

I am in the process of getting my banshee motor back together. This was a barn find so what’s been done was unknown before i bought it. I purchased a clutch pack for FAST to put in it. When I pulled the old clutch pack out found a few things wrong. It has a Hinson Racing basket in it. But I found the thrust washer between the clutch boss and basket missing, I found the O-ring behind the clutch basket missing and the cushion ring/rings missing. I also found that the main bolt holding the basket on was loose. The parts missing are #13,#15, #17 on the diagram. Did someone leave this out for a reason? Should I put everything back per the diagram in the repair manual? Any help would be greatly appreciated! I have attached photos for reference. Sent from my iPhone using Tapatalk

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

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

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

Update! I pulled the head/jugs tonight. 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 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. Is this a good or bad engine setup ? Also where can I get new rings/pistons for this ? New gaskets/seals for cool head? I also attached photos of part numbers. Thanks you! Sent from my iPhone using Tapatalk

Suggestions on a billet water pump kit? Thanks for all the help! Sent from my iPhone using Tapatalk

How can I tell if the clutch is good still? After getting it running after it sat for a while I filled with new gear oil. Found the oil looked gray/milky when I drained it. I’ve heard it could be clutch material or water pump. Here are photos of the outer case and oil. Is there a reason for a hole in the case? Clutch adjustment ? Sent from my iPhone using Tapatalk

I also found this on the inside of the case for the kick start shaft. Are these supposed to be shims or do I have another issue ? Sent from my iPhone using Tapatalk
