The rear drive vents through the transmission in theory. I've never found the need to add one to the rear drive. None of the Loop (or Tonti)rear drives came with a vent from the factory. I do "burp" the rear drive though - get it up to operating temp, remove the fill plug, replace the fill plug. Don't over fill it - only 180 cc total.

I didn't have a loop frame model, but that reminds me, I noticed several times that my 850 Tonti braked quicker if I pulled the clutch as well. |

Thanks Dave, I thought a heavy flywheel meant better engine braking
And thanks Amboman, I've burped the bevel twice, but never measured it in dead accurate, just waited till it appeared at the level plug. I'll be more precise next time and see if it helps. Cheers, Paul. |

Tonti brakes are better than loop brakes.

The Loop flywheels weigh over 13 pounds and that's without the ring gear and the clutch components, plus the weight of the massive spinning crankshaft.For comparison the LM1 flywheel assembly weighs little more than half that of your Loop.
I weighed the flywheel assembly of a Panther M100 that I used to have many years ago and that must have been the daddy of 'em all, just shy of thirty pounds. Edited by Dave P. - 29 Sep 2020 at 21:40 |

'm just pleased that's how they are. My previous Guzzi history- Cali EV, Centauro, modern V7,all had strong engine braking.
The new rubber looks a bit lost, downsized from 120s to standard. I'm sure it'll handle better Shockers next, rebuild or refresh. What are you guys running? Cheers Paul. |

If you find anyone who will/can rebuild the original shocks please let us know. In the meantime, Ikons seem fine on both of my Loops, they were already fitted when I bought the bikes. Hagons should be fine and somewhat cheaper. Hagon will fit the correct springs to suit your requirements if you ask them to.

Ikon has a line of less expensive shocks called "Basix". Non adjustable damping, adjustable spring preload only. But, they're very good quality and rebuildable. Actually priced less than Hagons cost in the US. I've installed a few sets on customer's Loops and they all seem happy with them.

Thanks again Amboman, had a look at the Ikons, liked them, ordered them
The correct size rubber might not look as good, but it sure makes the old girl agile. Had another nice 100 mile ride again, all good at the mo. Cheers, Paul. |

Thought I'd post an update seeing as no more riding for the next month
Really pleased with the Ikon shocks (thanks again Amboman). The old girl's running well-thank the gods. I've got a couple of annoying oil leaks, one from the bellhousing breather and one from the clutch pushrod (I replaced the o rings). But these are minor niggles after two engine rebuilds .Any one got a nice mirror they want to sell me? Anyway here's a photo. |

Excellent, nice to see another Loop on the road.
I'm not sure what you mean by the "Bell housing Breather" |

Hi Amboman, A question to you I have a 1971 750 that I am reviving, most of the insides where very good it has cast iron bores however after cleaning the pistons there was a lot of pitting on top and to the sides the engineer said maybe change them as the ones on the side are bothersome . So Gilardonis ? no as all shops I have tried are out of stock and the company itself doesn't know when and if they will be available. I came across some new asso pistons I am wondering if they are compatible I think only the A's are available . I am trying to find specs on the Asso's however not finding much luck, so I am trying here. Is there any info that you could share that might be beneficial for my dilemma ? Thanks James

Asso makes excellent quality pistons. The "A" is a size grading due to small variances in diameter. Is there a letter stamped into your present pistons? It should be somewhere on the crown. The other consideration is to make sure they are V7 Special/Ambassador pistons and not 850GT/Eldorado pistons. They have the same 83 mm diameter, but the compression height (distance from the pin to the crown) is 4 mm different. Also, the Ambassador pistons have a domed crown and the Eldorado pistons have a raised flat top. Mark Etheridge @ Moto Guzzi Classics in California sells forged CP Pistons that he had made to spec. They are slightly oversized to accommodate cylinders that have been damaged. Not inexpensive, but very high quality. If interested, call him at 562-986-0070.

Hi
Thanks for that, they are domed . Another question what would installing these pistons do to the balance of the engine is there anything else I should know ? Apparently they are matched with Kenig pins and they have rings and clips supplied . Have you heard anything of the re-manufacturing of Gilardonis and is there another outlet that still sells Asso pistons in case the measurement of cylinders require a B or C rather than a resleeve if at all needed? I have also contacted Mark I will await his reply. Thanks for your info muchly appreciated . I hope your country can find its peace. Thanks James
