Hey John---Since there is still quite an interest in the cross over intakes and your offering more new ones---And it seems your expanding your product line---How about some main jets that go with the cross overs---Apparently most of the guys are drilling out smaller ones---Seems like that gets a little iffy---Just have em made up following Keihin pattern say from 200-240 or whatever you recommend especially for the stockers adding this as a DIY power adder.

Kenny, if you worried about drilling, Factory Pro makes OEM style main jets up to 250, this should be plenty of jet you would need.

Drilling the jets isn't a bad gig if you use a pair of vice grips and a drill slow. I ran drilled mains for a really long time in the 800 with no problem.

But yes, as Wapiti said, they make jets up to 250.

Interesting where can I find this Factory Pro? What size jet would the 5/64 and 3/32 be?

Drilling them is no problem at all. Saves alot of time and some money. I used a vice to hold mine while I drilled them. Took just a few seconds and was ready to go.
