OEM Part Name: Oil Pump Roller Bearing 10x22x20 Moto Guzzi Part Number: GU 92252210 Replacement Part Brand or Source: VXB.com Ball Bearings Part number or other identifier: TAFI102220 Differences from OEM (if any): unknown Website link for source: Vxb.com | https://www.vxb.com/TAFI-102220-Needle-Roller-Bearing-10X22X20-p/TAFI102220.htm?gclid=Cj0KCQjw9JzoBRDjARIsAGcdIDUslO9SQER-yicoUNRjbgM-2KopqbeCA3flFYA_HUbx1zJ2tHouzTIaAiBVEALw_wcB I just ordered one on Amazon for $20 delivered. Harper's has them for $42, MG Cycle doesn't have them at all. So I thought it might be helpful to post an alternative. Crusty looking photo is the oem part from Harper's: This photo is from the the VXB website:

As I recall, make sure your headlight is properly lit when the engine is running. There is a relay that can cause the headlight to not lit (watch out, there is a secondary light, a running light, in the headlight bucket that may still be lit). If the headlight doesn't have power the charging system won't charge correctly as it senses the state of the battery off the headlight circuit. Relay issues are a common issue with these bikes. There are better relays available then what comes stock. Start the engine, measure the voltage at the battery. It should be over 14 volts. By the way, as I recall 12.84 volts is fully chared for an AGM battery like the Odyssey.

So, coming home from a week entry level hiking in Switzerland I found the recently ordered phase sensor at my door. While I was so sure it would finally cure the heavy stumbling and missfiring which the bike had developed over the last 4 weeks - it did not. Also I have to correct what I wrote about the Hall sensor. While it's true that Hall sensors are prone to ageing and that they're sensitive to heat, it is not true that the sensor here is of this type. Instead it's just a plain cheap inductive device. Hall sensors always have three contacts, inductive ones sometimes too. On the picture you can see the coil holder with coil and core, the cable ends and the magnet. The sensor shown above most probably was still good, allthough the magnetism of the replacement is remarkably stronger (will it collect any debris even quicker now?). For the positive side: the inductive type should be rather robust, no ageing electronics inside. The negative one: at this point I still had no solution for the problems. In fact, as soon as the engine had warmed up, from 3000 upwards the tach needle again started waving, with the engine again producing the same enervating bucking as before. The ECU at 3000 clearly got kicked out of sync. Long story short: the problem were the cheap silicone connectors on the inner spark plugs which I had installed also 4 weeks ago. As the outer ones (this engine has dual plugs) have the standard 5kOhm connectors, electrically/theoretically (or v/v) this should have worked. That it obviously did not might be due to the fact that these shitty aftermarket caps are so cheaply designed that they don't securely contact the plug. The resulting firing then induces enough noise into the signal cabel to screw the ECU. Theoretically. Anyway, solid connectors now and all is fine.

This screen is meant to keep large particles from entering the pump/hydraulic system . These particles , once they get into the system will damage the pump and attack the relief valve and any rotating parts that rely on pressurized oil for lubrication and clearance . If this pick-up is covered and smothers the supply , then you get no oil to the system and everything is destroyed . There are schools of thought that want no screens or similar coverings over the pick-up tube , Me , I like something over it .

I’m a ‘sump dropper’. Always have a snoot at the wee mesh but it’s always clean as a whistle. 🙃

I can't believe I missed all this. I have been a customer of Dave's since 1988. I bought my 1988 Cagiva Alazzurra and 2001 V11Sport from him at the various shops he was involved with in Seattle. I swung by last week to ask about replacement u-joints for the V11 and the shop was long gone. The was there last Fall and thought it seemed awfully quiet. Dave was there and we talked for a while. What a loss. Good things can't go on forever.

Here's a pic of what I found in the sump of my engine in 2009. Not in the mesh, though. Looked it up: the ends of what is called "gudgeon pin retainer".
