    Question Help with Jet log sizes

    I recently got a lot of dredge parts and want to build my first 6" dredge. I'm missing some parts and want to order them and build the dredge to take to my claim this spring. I got 2 GX270 9hp Hondas with 4x3 keene pumps. I did not get a 6" jet log tho, my question is should I get a jet log with two 3" jets or two 2" jets and reduce from my 3" pumps down to 2"? I see keene sells both logs. My thinking is keep it 3", easier pluming. Any help would be great.

    Ask the dealer on the best choice for your set - up!

    Ok, guess I'm on the wrong forum. Though someone would say Oh you need to neck down to 2" to increase pressure or stay 3" the log reduces it or.. I'll call keene.

    3" logs, the one with 2" logs is for twin p280's or p180's the jets are tuned to the engine pump combination.

    the other question would be "standard" or "over size" jet most of the newer jet flairs take the over size
    with the bullet that's glued on to the suction hose, older ones or crash box style take the standard jet.

    Good certification on the standard/oversized, I'm familiar with that part. I have a friend who has two 6" dredges who told me to buy the log with two 2" jets, I new that did not sound right at all. I think he must be running P280's.
