I got a 98 blaster from a guy he said he put top end on it it ran for 2 hours and cut off so I buy it I get it home long story short it was the top end it looks like the piston on the exusht side look wore down to the rings were broke and the piston pin was stuck inside the piston so bought new top end and fixed it seems like it's running great lots of power however after 2 hours of running I changed the oil and there was metal shavings in it.... seems to me that there more then should be in there. Did a temp reading after riding for 5 to 10 min it read 228........ any help or suggestions? Also the top end seems to be noise first blaster I have had. But I have had 2 stroke before all liquid cooled. I have the mix 24:1 and have not had it pass 1/4 to 1/2 throttle. Thanks for your help.
