Rebuild Questions

[masterblaster97]

I am in the process of rebuilding my Yamaha Blaster. The new bore will be .060mm over (67.5mm). Will this be reliable? Also, I bought an FMF power up Jet Kit. I need to know approximately what size jet to use. I have an FMF Gold Series Fatty Pipe, with a Power Core 2 silencer, and don't forget the bore size. So if you could share some knowledge with me, that would be great. Thanks

maybe 240-250. try the 250, run it a little, pull the plug. if it's black/wet, its too rich, try the 240. if its grey or tan it's good. white is too lean.

Probably around 250-270. Depending on elevations and sh*t.
