meanwhile, gary help me to hone the cylinder to fit the size of the new 0.25 piston ring that we ordered. after a few minute of work, we find that the 0.25 ring is too tight for the current cylinder. a few method we could get the piston ring fixed:

1) continue to hone the cylinder and take out more materials to fit the 0.25 rings and file the end of the rings to specification.
2) order a set of OEM (original) rings from singapore again. (got to wait)
3) purchase a set of OEM rings here in usa but the problem is:

can u advise me if the shadow 750 piston ring fits into my bike?
my VIN number is JH2RD07A9WM302728.

a kind soul from HUBB left a message for me:

Hi!
If you have covered such a high milage with a faulty air filter, probably you will need some new rings...it is a simple task, you will just have to deglaze the bore and fit some new rings. When you do that , just replace the valve seals and this should solve your burning oil problems. You can use Honda Shadow 750 rings and valve seals, since both models share those engine components ....and Shadow 750 was widely available in USA market...
It is :

13011MV1305 for the rings
12208-413-003 for intake valve seals
12209-413-003 for exhaust valve seal
World of Powersports w/ MC MART's 2000 Honda Street Bike VT750C SHADOW Parts Finder this is Honda Shadow in States...
Motorbike components for Honda XRV-750-W (G) this is Africa Twin in Europe...

what is your advice folks?
