needle and seat part difference,s

[fj11.5]

Hi all, I've been given a complete new in packets needle and seat set, other than the center hole , is that the only difference gravity fed and fuel pump parts , as these are for a 93  model , mine is 84

[Arnie]

Yep.  Big hole for gravity, small hole for pump.

Cool  thanks, , now to fuel pump. Or drill holes out

Is the float needle different for the different seat size, or just uses a different portion of the sealing tip?  Iono.

I believe that slowoldguy (David R) has put fuel pump carbs in his bike (85 I think) w/o any mods to the carbs. Fuel inlet will be the only problem and that's not that big of a deal. He says it runs fine.
Maybe he will chime in.

David R uses the wrong tires, don't ever listen to him for advice.

You are working to hard...

You can just use your old brass seats, they never wear out. It is the rubber tip of the needle that wears. You can use the new o-rings from the new seats on the old ones and then use the new needles.

And to answer Andy's question; the needles are all the same, it is just the hole size that changes. Now, with that said the float height had to be set differently as the needle goes deeper into the larger hole to seal.

That's what I figured, it'd make the most sense to have just a single needle if possible, fewer parts to stock.

Thanks!

Thanks everyone, makes sence randy, will save trashing the new seats with a drill, ,had a fuel pump for awhile, but had overflow issues,, , what tyres Does David use , they the old Harley style lol , I'm using metzeler and dunlop at the moment, but have a pirelli for the front waiting , so I shouldn't make jokes about hardly desirable,s

The pump-type carbs work so well on my '85 that I totally forgot I had them installed.  I used one of the T fuel fittings from the old set as the single inlet on the new set.  I think Randy offers a replacement fitting for the center carbs which would allow retention of the double inlet setup.

And damnit I can't think of a good come-back to andyb.  :-(

"Oh yeah!  Well I faked mine too!" (name that movie)

andyb, You're right about those tires, he uses those tires that don't have any tread on the sides

Hey Joe,
Nice riding with you in Arkansas last week! 

The ticket slowed us down a little, but I really enjoyed the pace.  It allowed me to gain back some confidence I lost after hitting gravel back in the spring.  I'm still a little spooked from that.

Once the ticket clears deferred adjudication hopefully I'll be back up to full speed.

Also, great kid you have there, everyone was impressed with him.

His not-so-great come-back when Madelyn Smith is leaving him and tells him that she faked all of her orgasms.

David,
  Dan & I really enjoyed meeting  & riding with you guys. When we stopped on Push Mtn. Rd, I explained to him lean forward and look over my inside shoulder, you could tell when the light came on for him. After that, we had a fighting chance of keeping you all in sight. Well, almost . I understand what you mean about the gravel, I watched the video you posted from your spring trip. It looked like a high pucker factor moment, for sure.
Dan's mom & I appreciate the positive feedback, we think he's pretty exceptional too! Of course, we might be a little biased....  He is still talking about that 250 Ninja.....I'm not arguing either....
