Hello, so thankfull to find a knowledgeable forum for yamaha! As you can see i got a yamaha chappy lb80. First few months it was running great, Lately ive noticed a serious lack of power. Everyone ive spoken with says no bore kit exists,   And to bore out the cylinder would be a custom and rather expensive job. Any advice for a newbie? Thanks!!

This section is for saying hello.

You can post your problem. Whatever that actually is? In the workshop section.

Im not sure if you want more power or your bike is losing power. Remember the detail. Helps a lot on forums.
