    Modded GP1300r FI with powervalves burned up piston

    A customer of mine has a lightly modded GP1300r. It has free flow exhaust, reeds, reed spacer, jetworks water valve, and an EJK controller. I overhauled it 2 years ago after his SBT engine blew up. This year, running great (65+mph) then stuttered and limped it to shore. I found no compression in center cylinder. Have a look at the pics....obviously leaned out but why? Bad injector? Front and rear cylinder wash looks good.

    What do you guys think?

    I'll check it out a bit closer maybe next week when I pull that cylinder off.
