When I needed a replacement rear drive, I got one from Italy. It was in good order, except for freeplay that I thought was too high, been that way from new. The workshop manual did not help me, it is sparse and seems to apply to earlier models. I made pinion and crown wheel shims, then made tools (a bit crude) to allow measurements. After 14 tries, I eventually got both preload and freeplay low enough to be happy with. A slow and tedious process. Contact impression interpretation is a black art, with vague contact marks that need a strong light and a good imagination. You will never get it perfect on a worn C&W set. The bevel box is now quiet and runs cool. However, if your box is ok, then the only maintenance needed is oil change and spline grease.

Do you have a drain bung with a magnet in it? Just in case there is still a few bits in there.

I took Cash1000's RM flywheel to the NDT dept at work. I showed them pictures of cracked and broken flywheels, so they knew what to look for. The next day they said "No cracks. Surprisingly it's perfect". Edit: this is an aluminum alloy flywheel. @cash1000

OEM part Oil pump needle roller bearing P/N GU92252210 Replacement Part Bearing P/N NKI10/20, size 10x22x20. Difference: Single row of longer needles, instead of 2 short rows. Source: Any good bearing retailer. Oh, I see there is a reference for another alternative already:

A new bearing has fixed the shaft slop. It cost $40 instead of a mega squillion for another pump. The new bearing has full length needle rollers instead of two sets of short rollers. Roller Bearing P/N NKI10/20, size 10x22x20 (same as GU92252210).

Did you lubricate the seal with new oil before you fitted the new filter? It lets you tighten the filter without tearing the seal.

@Scud had low oil pressure in a V11. I think he found a broken out bit of gasket where the oil module meets the block. With a Roper plate, you have 2 gaskets to check. https://www.v11lemans.com/forums/topic/22545-low-pressure-oil-light-on-at-idle/page/2/#elControls_259408_menu

Has the oil filter partly unwound?

Well yes, any metric grade 10.9 bolt would do if it has: - Rolled, not cut threads A section of plain shank to fit the hole snugly A head size that doesn't interfere with the clutch. The genuine MG part has already taken care of these considerations, and I see MG Cycle sells them for $1.68 ea. Since it's standard on lots of models, I'd ask Motokiwi for a price.

I've got the alternator off my bike at the moment. You are welcome to come over to look and see how little it will help with accessing the clutch. BTW, the manual says "Screws “B” (flywheel bolts) must be replaced with new ones upon the following reassembly, due to the high load and stresses they are subject to; (apply thread locking product, Loctite, medium strength, to the screws and tighten to torques of Nm 40 ÷ 42)." P/N GU12067701 Qty 6.

I see that HMB and Stein-Dinse both offer their own alternatives to the MG design, and I believe that the bearings are included. They also both sell the woodruff key GU13148300 that was missing from my pump shaft. The bike shows 53,326 miles (85,819 km) on the speedo.

Thanks, AudioMick. What do the German speaking people think of the Stein-Dinse pump? It is a lot cheaper than the HMB pump. Moto Guzzi Oil pump ŽspezialŽ - big models - Stein-Dinse Online-Shop

I decided that I had a loose timing chain after a timing light showed erratic movement on the flywheel as rpm increased. I tried to get video of this, but it was beyond the combined abilities of borescope, old workshop laptop, & me. The obvious fix was a new chain & tensioner. I chose the more expensive gear replacement because, um... Now I find that the oil pump is worn. The needle roller inner race is grooved, and the shaft has 1.5mm slop. As the direction of side loads on the pump shaft are opposite when changing from chain to gear, a new one is on order. A Valpolini gasket is waiting to go on after the timing chest cover is powder coated. I tried to remind myself of a lesson from my father: "If it's not broken, don't try to fix it", but I'm a slow learner.

Joe uses a very good grade of steel, EN24T, typical for gear and heavy-duty shaft manufacture. Joe says: "Machined from EN24T. This is a Nickel Chromium Molybdenum that combines a good high tensile steel strength with shock resistance, ductility and wear resistance with a tensile strength of 850/1000 N/mm². The Gears are then further surface-hardened by a Tufftride process to give an enhanced surface wear resistance which gives the finished black surface".

That works for me!

I have a 1 tonne chain hoist and straps you can use to secure the bike steering yoke to a beam.

Not just one member...

I thought " kill switch" but no that doesn't affect lights on my bike. Same with the phase sensor on the camshaft, which can be intermittent before it fails. Could there be a wire loose/broken in the birds nest at the battery? Or a broken wire at the base of the ignition switch. Or a connector coming apart at the steering head.

This guy had one for sale a couple of months ago, but the listing closed. Maybe you could contact him and ask. The price was good. https://www.ebay.com/itm/364001406540?hash=item54c02cae4c:g:URcAAOSwWKdjB-7t&amdata=enc%3AAQAHAAAAoHvRSgDK9%2FZtCXarQWbuFm9XemjrmLqhNgWPIRIrnNnrHSJiwGG5BudPuktlduxUWdvOtxb33jR31Hd3J24rxawnLeNxXqxLzaGMMIVr%2FHJIz64fPprWOmqwrkF%2BPyBEsworWRIsp%2BCPQNZR6BacfJ54Qq0xKgdMkyljuRZS0fSkakwElkvpxbKp08E%2FpgKvTPtGaLixtQ3l5DE%2Bpr81Znw%3D|tkp%3ABk9SR6bHuqT0YA

Have you checked your 30 amp fuse? https://www.v11lemans.com/forums/topic/19672-30-amp-fuse-failure/

My bike is ZGUKRAKRX3M114954, which I interpret as a 2003 KR. It has a long black frame, extra gearbox brace, external pump, and short chin pad tank. https://www.v11lemans.com/forums/topic/7872-lemans-vin-numbers/?do=findComment&comment=88097
