Boom!

It feels like we’re running into more and more parts issues year after year, month after month (;\u00b4\u30fb`\u0434\u30fb\u00b4)
We really need to check things out and discuss the risks before we tear it down… <\/p>\n\n\n\n

Of course, the research takes more than the usual amount of time, so we can’t avoid increased costs (\u30fb\u00b4\u0437`\u30fb)
We found a reliable Yamaha OEM piston kit, so we’ll go ahead and assemble with this one~ <\/p>\n\n\n\n

This is a Yamaha SR400SP cast model piston.

The GX750 (XS750) has no piston parts listed
The SR400SP has a piston seal kit available

Both have the same seal kit part number = are the pistons the same or not? This is reverse-engineering at its finest.
We’re investigating this one carefully too… <\/p>\n\n\n\n
