GS850 intake boots on Amazon: Set of 4 for $31 free shipping

[Steve]

One thing that gave me trouble is the vacuum tuning ports on these mount facing down, not up like the OEM boots.

You must have had some incorrect boots or they were installed incorrectly.

OEM boots have the vacuum ports facing down and out. Probably close to a 45° angle.

The PO seemed like a cheapskate...odds are some other ‘Zuk boots then that just happen to fit if you flip them upside down. Never had a problem with them. 🤷🏻*@%^$♂️

Oh man, I got ripped off lol. Those have little tabs to keep the O-ring in place even, I wonder if that could cause issues as the O-ring gets heated and cooled over time? I also wonder if this set has the ID for the intake side correct, or if it the same smaller ID. Have you used this brand before?

[Andrew Vanis]

Any chance they would work on a 1983 GS750 E/ES?

@ $19 I'm considering giving them a try but all the part houses show different part numbers for the 750 vs the 850 (and mine don;t have the bold as they are on the cylinder) but who knows?

though I could get the 750 ones for $52 shipped ($13 each) from ebay

$13 each I would probably just pony up the extra scratch for OEM. I can get you some more measurements if you would like ie bolt to bolt, bolt to intake, total height, etc. if you wanted to compare to what you have? I would assume that since they are different part #s they are different specs.

I just got on here searching for quality/user reports on these Caltric intake boots, after finding a set of 4 on eBay for GS 650 models at around $89. I cannot find them on Amazon for as cheap as the 850 models unfortunately!
The GS 650 head if I recall is only about 28 mm ID on the intake side where the boot bolts up, so the smaller size on the 850 makes sense for this model, but perhaps not the 850 head!

OEM ones ar $36 each + shipping .... 3x the price. Not worth that much to me

Bob I will get the measurements for you this evening, didn't see your message until after I had already left this morning.

Just as an update I was able to get the pilot fuel mix screws down to 2 3/4 turns out with a stable idle by changing the pilot jets from stock to #47.5s. It runs well by ear throughout the throttle input range now, no stumbles, backfires, or bogs. I may do a plug chop test this weekend to make doubly sure what I'm hearing matches some tangible data.

anytime is fine, still mud season in vt and roads are terrible. feels like it'll never dry out, for carb tuning.
