    61X Engine Build — big bore, porting, crank, jetting

    I’ve got my 95’ blaster torn apart right now and trying to get it ready for the summer. I got a few questions about boring the engine and re-jetting, etc. I’ll let you know what I’m running and the whole setup I have so you have a better idea of what I’m working with. -61X bottom and top end...

    Porting templates

    I read a while ago that someone has templates for DIY porting for the 6m6 or 61x cylinders... I'm looking for a DIY for the 6m6 ports. If anyone has them, or can direct me to the right place... Please let me know. Thank you, David
