You guy's w/ carbed Monster's..do you have issues yearly?

[ducpainter]

Yes.... I plan to that too
Do have a particular one in mind?

I used a Pingle copy from Parts Unlimited.

I haven't actually looked around yet to see what's out there lol. I'm currently in the middle of getting the frame powdercoated, cleaning everything, re-lubing everything, and overhauling the motor. so my main concern right now is just getting all that work done first, letting my bank account recover, then work on the little stuff :p

you might want to do an ignition timing check, it may or may not be off. our bikes are set up (ignition included) to run on premium, even though it totally isnt necessary with 9.0:1 compression. you might find the timing is a bit retarded. If it IS retarded, setting it back to stock will actually give you a bump in power as well.

Did some research... I'll have to check it!  Thanks for the heads up.  FYI - if you have hi comps, you want it to be 2-3 degree advance.

If you have hi comp oistons you should retard your ignition 2-3 degrees. You can get bad pinging with hi comp pistons with standard ignition tkming, so advancing the timing could hole a piston.
Check the search function on this for ways to do it and check the bikeboy site.

My mechanic stated with quite certainty that my carb issue IS more than bad gas buildup.....he says last time (cleaned up the carbs) ....there were fragments which he
believes to be from the diaphragm of the fuel pump...?

My question is a new fuel pump or get a rebuild kit?

Also, I want to get a in line fuel shut off valve.....all the 5/16 ones I have come across say not to use on 300 cc or larger motors!!!?  Not enough flow volume?

Thoughts?

[DesmoTull]

Get the square one from CA-Cycleworks.  That's what I did, works like a champ.

rebuild kit for sure. a whole pump is very pricey. and the only things that can fail or not function properly or break down are the gaskets, diaphragm, and check valves, all of which come in a rebuild kit which is crazy cheap in comparison to a new pump, and extremely easy to replace.

the only way you'd want a whole new pump is if the inside of the pump is insanely corroded for some very strange reason and can't be cleaned out enough to get rid of all potential particles falling off into the fuel

[DesmoTull]

A whole new pump is $27....

<-- insert foot in mouth
I swear I looked it up the other day and saw like $150, as compared to a couple bux for a rebuild kit. guess I was wrong, ignore my above comment haha

edit: I was right! I just looked it up again and a whole new pump is $154.99 from Ducati Omaha online. I see the one you posted is "a suitable replacement" though. well, thats what we're all here for :p
I personally would still just get a rebuild kit for the OEM hexagonal pump

[118811]

Thanks Guy's for your opinions!!
Ducati Honolulu quoted me $169 + tax...and had to be ordered from Italy.

I am leaning to the rebuild...

To each his own.  I go with what Chris Kelly recommends.  

Chris is one of the guys who's opinion I take as solid gold.  Same goes for LT, Bruce Meyers, Eric Colbath, and a few others in the New England area.

The fuel pump (square one) from CACycle
Is it direct bolt on or is fabrication needed?
Thanks

If you decide on a rebuild stay away from the Winderosa kit and go with genuine Mikuni.

The mounting holes are different. If you want it to be real solid, you might want to fab something up.  I just screwed it down on 2 side, and it's mounted well enough for me right now. Might try to clean it up better over the winter.
