This is copied from another place: (EDIT/May 2019): Having had two TPS go bad after 50,000-62,000 miles/ 79.000-100.000 km, it is simple enough to check the TPS when it is hooked up to the DVOM (Digital-Volt-Ohm-Meter) . Switch the DVOM to resistance in the 2000 Ohm range with the key off. Slowly and smoothly open and close the throttle body and observe for a smooth transition of increasing and decreasing resistance from the potentiometer (TPS). If there are jumps and glitches or drops and variations in the resistance, the TPS should be replaced. Be certain to set the DVOM back to > DC voltage < before baselining the TPS in millivolts or you'll think something is terribly wrong! I have both analog and digital multimeters. I would think that the analog version would be better to read. Anyone have tried this? (I will try with both instruments in a week or 2). Rolf

I also have the necessary tools to work with this gearbox - for sale. Rolf

This new case comes from the 2004-series V11 Sport. I have not heard of any such models having problem with cracking gearbox house. They are 100% identical with the first 2000-models, but many things may have been changes to the better in the production. Alu-alloy, casting prosess, bigger radius in corners etc. Why use time and energy in trying to repair, when you can just put in a new part. I think the cost will be around the same level. Rolf

Thin walled cast cheap aluminum-alloy. Difficult to make a good repair. Change the house to a new house (matt black - not wrinkcle paint). I have this part available for you. Part No: 01200290 Rolf

I have the part 120290 - which is identical except with a smooth black finish - not the wrinckle paint. A few weeks ago I sent one case to another guy in New Zealand. You can contact him if you want to get references to me. Rolf

My pipes are the same an your number 3, 4 and 5 in the second picture. Rolf

These are my tools. Rolf

You can do without that compressing tool if you have access to a hydraulic press. I have the other special pipes (3 different) you would need to fully dismantle your gearbox - plus the one centering tool needed to renew the clutch plates in the future (you will need this sometime). These 4 tools I have for sale. But I am living in Norway so send me a message if wanting more info. Rolf

Back to V7 Sport design of 1972.

I have some reproduced decals for Rosso Mandello (under the sadle). rolf.halvorsen@mail.com Rolf

I will travel to Kiel in April. Arriving there 16. April at about 10.00 I could bring with me the gearbox and we could meet then. Rolf

Hi Netherland Take out your old gearbox and replace it with one that is fully restored (and got fresh sealings and sealing liquids in the joints). Your question will be: where can I find such a piece. My answer: By me. I have a retired engineer and restores gearboxes and rear drive "for fun". In my shelf I have ready one from a 2003 V11 Sport LeMans. The same black wrinckle paint as the Rosso Mandello. Which clutch do you have? Single plate or twin plate? (I have a twin plate clutch also available.) Contact me directly if this could be an option. My parts is not cheap - but I believe the quality and price fits to each other. The negative is that I live in Norway (outside EU). Rolf rolf.halvorsen@mail.com

Nobody in Europe stocks 'em. I've never been approached by anyone. Air mail fro Oz costs about $27AU I think. Pete Pete Send me one so that I can be convinced and present the part to the SPRING meeting here in Norway. If I like it - I can be your European representative - although Norway is outside EU. Rolf

The gear box housing consist of 3 parts. I think Luigi has forgotten to use any liquid seal in the joints when he assembled the gearbox. I have seen many such gearboxes (first design of the six speed gearboxes from 1999 - 2005) with leaks, and all exept one came from leaking joints. Only one have had cracks in the front part house. Rolf

Yes I have a special tool for that removal as well. Rolf

I am sorry about the quality of the attached picture. I am too old for this computer world. Rolf

Here are 4 of my special tools for Moto Guzzi

My tools are much better than Moto Guzzi ever have made. They are professionally produced after my design - and since I have been working with Guzzi for 20 years and have worked with technical design connected with rocket motors - I sure can say I have relewant background. You need only 2 of my 7 tools to open the 3 special nuts.

I have both the 2 special tools that you need to unscrew the special nuts thats hold the axels. Since I live in Norway - it would be best if users in USA would buy them. And a warning - they are not cheap, but are the best money can buy. Send me a mail and I will respond with pictures and prices. (I also have tools for the 5-speed gearboxes.) I am sure that there are people in this forum that knows my tools and will report in. rolf.halvorsen@mail.com
