Make these adjustments at full operating engine temp. Combustion speeds are at their highest at temp (if jetted correctly of course).

If it's an aftermarket stator back plate and is adjustable then the plate will need to be turned counterclockwise to pull back timing. The middle of the adjustable screw slot is usually the place to start but these aftermarket stators are not all the same so test and adjust.

The ignition is too far advanced

Did you forget to install a plate back on the basket? 1/4" seems excessive gap at full disengagement.

How ARE you measuring everything? Piston rings are only measured by its end gap once it's squared up into a "PROPPERLY SIZED AND CONDITIONED" Bore. You will need at the least a set of feeler gauges, 3" Micrometer and a bore gauge. You also need to know how to properly use those tools top get...

You need to remove the transmission shafts and that shift fork shaft before removing it. What are you trying to do exactly?

Also wanted to mention that you are incorrect with ring gap. first off you only measure the outer (smaller) gap and the specs are .008"-.014" and the larger the oversize piston the closer to the larger number you want. No piston ring is set at .000" clearance as it's there for thermal expansion...

You buy a good used one as close to stock bore as possible(66mm) and send it off to a shop (like mine) to get bored and honed matched to a new Oversized piston. The cylinder gets measured and depending on how much material needs to be removed(bored) from the bore to get right then the machinist...

Recommend All OEM (or Japanese Equivalent) Components for entire motor with the exception of a Wiseco "Piston". OEM Gaskets (or Japanese or USA Equivalent). The old style "Black Con Rod" Wiseco cranks are junk. Find a clean OEM Crank and have it rebuilt "With Japanese parts" and also find a good...

Everything is wrong< Chinese Ebay cylinder, Junk Wiseco Crank, RVT used throughout. That entire motor needs to come completely apart. DO NOT watch YouTube to learn how to rebuild motors as 95% of those clowns are full of BS. You can't inspect a crank shaft with your hands and eyes. You need mag...

Judging by the presence of RVT for a base gasket I would say that the entire motor is suspect at this point. God only knows what stupidity lurks within.

I do that service here and do them ALL the time. Your cylinder is out of spec. Give me a shout. You can find me in Facebook at CycleTech Performance and also my website cycletechperformance.com I have a fast turnaround (At the moment lol) so get in touch soon because the shop gets crazy at times.

That right there will have you chasing your tail for a while!

For future Reference guys I recondition cylinders and cranks so if anyone needs those services and any other engine work or mods then contact me.

Did this bike have comp before the fire?? The fire was probably caused by the lack of comp. The previous owner was maybe trying to start it and because of its underlining issue backfired through the carb and caused the fire? How did this turn out? Did you diag your issue?

Love real music first thing in the morning! Thanks!

So what happened after sealing the cases(especially around crank chamber)??

Just run the tank down to almost empty and fill it with the Yamalube. No need to overthink it.

My goodness what a mess. Too bad you are not close to me.

I think you should bring it to someone.
