JE Big Bore Kit??

[rooster300ex]

This kit says it doesn't require a big bore sleeve. I don't understand that. There is no way you can bore & hone a stock sleeve to a 330. or can you? Its on ebay, do a search for 300ex big bore and it will come up.

yes,that kit is designed to use the stock sleeve.how do i know?i asked the sellers that awhile back.there will be plenty of cylinder left once its bored out to 80mm.(330cc)unless you plan on running nitrous you wont have any reliability issues
