  • @gilera-sc you can get impact drivers that you hit with an hammer and it turns them loose they are really good and should be cheap they are your best bet but if they’re rounded a old flat head and a hammer and hit them so they rotate left and that works too but only as a last resort



  • Imact driver all the way as @declan says. They are a life saver for these engines!

    Otherwise it'll be to drill the heads off.



  • A lot of the time the problem is caused by not having the right tipped screwdriver. They're not Pozidrive or Phillips they're actually something called JIS (Japanese industrial standard) I think that's why so many get rounded off.

    But yeah get them out with an impact driver and replace with stainless capheads



  • What I did was use a makita drill along with a screw extractor kit



  • Right also, don't be so quick to slate Yamaha for using the bolts that they did.

    I'm not going into here, you can easily Google that information, but trust me when I say there is a perfectly justifiable reason as to why they used the bolts that they did.
