not all the bolts thread into nuts though

It was a 513 series piston wasnt it? I thought the 513s have stock pin height for stock length rod and the 795s were raised. If not disregard what i said

the pistons you have are stock pin height for a stock length rod, so assuming there is no spacerplate under the cylinders, the pistons should not be protruding out of the cylinders when at TDC. If they stick out 2 mm at the edge then its a stroker, if not its stock

gotcha i only saw the pics of the top of the pistons and the head.

I understand where you are coming from, i do. Unfortunately there is nothing cheap about these things when you really get down to it. If you take a shortcut you will just end up spending money twice. We arent telling you these things to waste your money and time, its because we have all been there and blowed that up. Ive nuked a few of these things over the years. Its better to prevent it than to pick up the pieces

good info, i didnt realize his cylinders were already ported, i thought he said he was going to have them ported.

because you are already at 65.5mm id honestly look for a set of virgin cylinders to have ported. No way im putting money into cylinders with at most a couple bores left when likely one of those bores is going to be used up this time. If you are going to dive into this thing i would highly suggest splitting the cases and inspecting the bottom end. You do not know the history because you bought it used so id make sure the bottom end is in good shape and the crank has been welded. If not its all going to grenade eventually

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.

Its really hard to tell in pictures but that pic makes it look like you have quite a bit piston to cylinder clearance. It needs to be measured at the skirt but for some reason that pic from the top side sure looks big to me but its been a while since ive been in one of my motors.

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

yes needs the check valve and correct adaptor. I take both plugs out, screw the gauge into 1 of the cylinders, hold the throttle wide open and kick the ever living hell out of it until guage stops climbing. remove switch sides and repeat

Feeler gauges or a gap tool, they are dirt cheap at any autoparts store. In a pinch you could use a matchbook cover but anymore those are pretty damn rare

Ive had terrible luck with aftermarket needle and seats. They seem to always leak. my guess is after your carb rebuild one or both of your needle/seats is leaking

If you have spark then the issue has to be timing or fuel or lack of compression. What have you checked?

as long as you identify as tall you are good to go. remember feelings are more important than facts

fucking gary engraved dicks on my stator, i need to post pics. He really does have a thing for dicks

i forgot all about this

bwahahahahaha

if you suspect its an ignition issue try switching plug wires to opposite cylinder and see if the problem moves to the other side

Salsa recipe? WTF where do i find this recipe?

Shit sorry i misread, i saw honda and got excited. I suppose i could redrill them. hmmm

Mike, these are yamaha bolt pattern or honda?
