I am out on that one. For $40-$50 a hole I don't even mess with my own cylinders. Send them out and have them bored for the size piston I'm using. Done. Pistons today are accurate enough they don't need to be fitted. Just double checked. Sent from my iPhone using Tapatalk

Is that the stage 3 shock

No way to vouch for the work of your dads friend. We do know that the sponsors on here are good at what they do, which is Banshee stuff. Not that nobody else can do it but the chamfers have to be right so as to. Or snag a ring and two strokes are more particular than four strokes since your porting doesn't exist in the cylinder walls on a four stroke. Sent from my iPhone using Tapatalk

no doubt thats why i mentioned assuming there is no spacer plate. the problem here is we are totally guessing without detailed pics and more information.

Similar metals like to bond to each other. Try using TI to TI dry

not all the bolts thread into nuts though

We never did discern what the original leak was from. Lol! Sent from my iPhone using Tapatalk

I always use blue loctite on stainless. I like to use the "gluestick" form so there is no fucking mess. I hate using antiseize unless i have to cause that shit gets all over everything. the loctite provides some lubrication to prevent any sort of gaulling and keeps your shit from rattling loose and falling off. Blue is easily removed with hand tools so no worries there.

A lot of the times they are marked. pull the dome out of the head and look for markings around the outside edge. ** IF that is a stock stroke motor and you were kicking 180 psi im guessing you have about a 19cc dome. My stock stroke dune ported motor kicked 185 with 19cc domes and requires 110 octane. At this point id pull the cylinders and pistons and inspect everything. Honestly if that thing was really running that high of compression and you were running pump gas id probably tear the whole thing down and inspect. Detonation can very easily and quickly kill bottom ends too. You are going to have to decide how steep of a learning curve you can handle to get this thing back to proper working order. You can learn most of what you need here but its not quite as simple as throwing parts at it when you start talking porting and compression ratios etc. Your best bet may be to pull the motor and send it to a builder on here but at a minimum im guessing the cylilnders are going to have to go out depending on what the they look like. the fact that compression iin 1 hole was 50 and there is no hole in the piston makes me think the rings/bore is damaged

No i meant its possibly for him to assemble everything himself and save money. Obvi an oversized bore from a builder of choice with new pistons is the way to go

Omg, you're gonna confuse this cat beyond. Sent from my iPhone using Tapatalk
