## Overview

The PP2821 Motorcycle Tool Air Mixture Carburetor Pilot Screw Adjusting Tool by Pit Posse features a gear-driven 1/4" hex head with an aluminum handle marked for precise tuning. Its compact 90-degree driver design allows access to hard-to-reach carburetor screws, and it comes with a comprehensive set of common bits compatible with 1/4" and 6mm hex sizes. Ideal for professional-grade carburetor adjustments, it supports up to 55 in. lbs. of torque for controlled, accurate tuning.

## Description

This tool makes those hard to reach carburetor adjustments easy and safe. Aluminum handle includes index marks for accurate tuning. Gear driven with a 1/4" hex head. Complete with most all common heads needed, but any 1/4" or 6 Milimeter hex bits will fit. Includes strait slot, Phillips, D shaped pilot bit, 6 Milimeter hex jet bit and 1/4"drive bit. 17 3/4" long with max torque 55in. lbs. Driver with bit installed at 90-degree is 1-1/4" tall.

Review: Modify it first. - Works 100% after you remove the ball bearing from the device otherwise the friction is too much to turn handle accurately. The bearing is easy to remove and I just place it in with the fittings in case to save if I want to use it again. Be sure to tape the drive piece so it doesn't fall out of the socket like one did on me to be forever lost between the cylinders.
Review: Junk. - I needed one of these to adjust the six carbs on my bike. When I looked on desertcart for a tool to do the job I only found two available. One from Motion Pro and one from Pit Posse. Except for cosmetics they looked pretty much the same, and since the one from Motion Pro cost almost twice as much I bought the one from Pit Posse. When it came in I immediately knew it was junk. The gears bound up and skipped. It was totally unusable. I immediately boxed it up and sent it back. But I still needed the tool. After reading similar reviews with the same results I ordered the expensive Motion Pro version. They may look the same but there is no comparison. The one from Motion Pro is a quality piece made much better.

## Questions & Answers

**Q: can you get replacement bits for this ?**
A: yes, it uses any standard hex bit.

**Q: Do you currently have this item in stock as ready to ship ?  It appears to be back ordered with all . Just want to make sure you have it in hand**
A: as of this message we have one available for immediate shipment. Thank you

**Q: will this work on a triumph bonneville (2008)?**
A: A 2008 Bonneville should be fuel injected so this will not work. It has carburetor bodies but they aren't actually carbs. They're empty and are only have the throttle blades in them. Look close at the and you'll see wires coming from the carb...no real carb on a motorcycle has wires coming from them. If you're having to fatten up the mixture, you need to use an aftermarket programmer or call a Triumph dealer to see what tunes they may be able to put in it.

**Q: will it work on 1982 Honda GL 1100I?**
A: I believe it will. It is all a matter or reach, the bits that come with the tool are short and stubby so it depends on what is in the way on your ride. Overall I like the tool.

### ⭐⭐⭐⭐ Pit Posse 2821 carb adjustment tool
*by J***S on January 1, 2016*

My new 4 star review. I revised my original review (see below), after reading another purchaser's review of this product. It has a spring loaded ball detent in the handle that can be felt (its not the gearing in the head end). For this tool to really feel precise and provide proper feedback, the ball needs to be removed. I lubed it up a little and deburred a few areas, and it spins freely and easily, as I feel it should. If I had known this prior to purchasing, I would have been far more satisfied and been able to properly use it, for my purposes imediately (after the field fix). Had this tool came with some notation regarding this field fix, if the purchaser did not need the click/detent feature, It would have received a 5 star rating hands down. My previous 2 star review: I had assumed this was a sort of precision tool, even so much as the handle having index marks. The tool is designed for precise adjustments on carb idle mixture screws; my exact reason for my purchasing it. However, the gearing is so tight (by design) and gearing so rough (click, click) that I had zero feedback with the screws I was trying adjust. You cant feel the screw bottom out and you really cant tell if you have good contact with the screw at all. For instance, you might think you twisted a perfect 2.25 turns, however 1 of those turns, the driver was not properly engaged. Since, the gearing is so rough you cant feel if you are engaged on the screw or not. I give it a A+ on the converting the input action to 90 degrees in a very tight space, and ease of use. I give it a D- on the actual feedback the user feels while using this tool; rendering this tool useless, for my needs. I improvised another method that is working satisfactorily and I actually know where I am on the adjustment (leaps and bounds beyond this specialized tool). This is a tool, that I have now used, so I do not expect to even try getting a refund, but I am definitely letting other possible buyers know, this may be a waste of money for them too. $20 would be an 'oh well it didnt work for me', but $60 is far more disappointing, for sure.
