Have you ever used dynojets? If you have then you'd realize that a dynojet flows more at the same number than a mikuni. Every chart that I've ever seen on the intertnet is wrong. Includling the one you speak of at the ds650 site.

Gosh I really get annoyed with the bull$hit forbidden words in this place.
Go look at the site maddog56. It will only take a couple of mins. I would add a link, but this site has blocked that site. I cant even type the name of the site. Thats why I used [dot] in the address.

I looked at the site, its the same incorrect chart that has floated around the net for years. Thats why I got the forbidden word, I was trying to post a link to it.

If it's wrong, where is a correct chart?

Like I said, every chart I've seen has been like that one, and is wrong. I've yet to see one that correctly displays the fact that a DJ outflows a mikuni of the same number. Why else do you think that a stage 2 dynojet kit comes with 136-150 main jets when the stock Mikunis are 140/145? According to that chart just about every jet DJ makes for the raptor is smaller than stock.

Just for the sake of argument, say a dj and mikuni flow the same. Does it seem right that I would go 5 sizes bigger on my ds jetting {165 to 190}? Most people who ride a ds at 0 to 1000 ft elevation either run a dj 190 or a 175 mikuni main jet.

The only jet kit offered by DJ is the stage 2 for the raptor. Why would DJ send you 7 main jets that are smaller than anything in the bike, and one main halfway between the stock mikuni jets? Seems like they wouldnt sell very many of those to me, especially since the kit is for bikes with modified intakes and aftermarket filters.

Mikuni and DJ dont flow the same, DJ flows more. You're saying that at any given number Mikuni flows more. I have no idea what your question is asking, so I wont reply to it.

There are 3 types of mikuni mains, small round, large round, and hex. But I believe they all flow the same, just different design forms.

My point is, do you think it is normal going 5 sizes bigger in main jetting, just with a k+n, and slip on? Ds comes with a 165 mikuni mj. Most ds owners with the same mods use a 175 mikuni mj. 2 sizes bigger. If a ds owner uses a dynojet kit {like I did} we use a 190 dj-mj. I'm not trying to bust *****, but what proof do you have, other than your word, that what you say is true? How about a chart showing other wise. Where are the people who have used the mikuni vs dyno jet chart who are having problems? When I jetted my ds 165mikuni to a 175 dj, my bike ran leaner than with the 165 mikuni. I went to a 190 dj main jet. If I had put a 190 mikuni jet in, it would have been way too rich.
