Gotta love Guzzis for the simplicity of the valve job. You can do this in 30-60 minutes easily. On some bikes it's a job that takes an entire day of work
I've been avoiding doing this to my bike just because I was not 100% sure what to do. This clears up everything and I'll probably watch it 20 more times while I'm doing it 😆 Much appreciated from Pennsylvania!
Great video. For new folk both valve rockers have to be loose or wiggle when you tug on them, otherwise spin the engine to the other top dead center stroke. Love the tees! Ordered one.
There are many things I love about my 2023 V7 Stone 850, but none of them compare to the peace of mind that comes from knowing how easy it is to work on. Moto Guzzi is one of the very, very few manufacturers left in the world that designs products that owners can fix and maintain themselves. I'll be doing a full service on my bike next weekend, including a valve adjustment of course. Great video!
Mike its amazing help for me! I read the manual and everything is too complicated there. If you want something done well, do it yourself!))) From russia with respect!!!
Okay thanks. I might be getting two old Guzzis in about a week. A 78 complete and a 77 in parts. It's 7/28/21 now. They've been parked for ten years. Any suggestions.
Hello Mike could you please explain us the exact procedure to follow in order to balance cylinders with an home made vacuum gauge and how to reset values with the Guzzidiag software and what cables and tools we need for doing this at home. Thank you
Great Post(s) and Thanks . Can I ask please why it is not preferable to find TDC with a rotation of the rear wheel while the Bike is in gear instead of taking off the front end stuff as you described ? What Gear would that be do you reckon ? Plugs out and cover off of course . I have been riding for 50 years now and this current recently acquired Breva 750 bike, my 1 st Guzzi actually, is so close to my 1 st bike which was a 73 Commando. Its not funny but freaky. I love it...
Either way is fine. I just find it more convenient to rotate the engine over from the front. I usually put the bike into top gear when rotating the engine over using the rear wheel.
Thanks Mike. So as long as Piston to the top and both valves closed. That’s the firing stroke for adjustment?Thanks again my V7 I’m sure needs same clearances. Thank mike appreciate your videos
Correct, the firing stroke is the piston at the top & both valves closed. The clearances are the same for the early V7s but the later models have different heads. Best to check in the manual first. You can find the service manuals here. www.thisoldtractor.com/moto_guzzi_small_blocks_workshop_manuals___shop_manuals___service_manuals.html
Have you produced anything regarding injector balancing and idle speed adjustment for the Breva? I did look but maybe it was in a video with other service items?
Is it mandatory to also balance the throttle bodies after setting valve clearance? I have everything I need for both jobs except for the Axone tester so there's no way I can do the TPS reset, nor do I have any way to find out when the engine temp is 50 and 90 degrees respectively for balancing the throttle bodies as described in the service manual. Again, thanks so much for your videos! They gave me enough courage to start and do the basic maintenance myself.
No but it is worth checking for good idle & smooth running. The major reason for change in the throttle body balance is wear in the linkage ball joints. You can probably get away without reseting the TPS though. It doesn't change that much I've found. In regards to temperature, it only really effects the idle speed not the balance. If you want to delve further into the ecu search on ebay for "obd Guzzi". You will find diagnostic adaptors and software for Guzzis that you can run on a PC for around $50.
@@MikesMachines thank you! I adjusted the valve clearances yesterday. The bike starts and runs so much better now. The only major issue was that I broke half of the slit of the adjuster rod on one intake while trying to loosen the nut (they were all extremely tight). I managed to adjust it but only used decent force to tighten the nuts afterwards. Is it possible they'll go out of adjustment easier now? And is it feasible to replace the rod?
The lock nuts don't need to be excessively tightened. The adjuster bolt can be replaced (part GU19034000) but you will need to remove the rocker bridge assembly to do it.
Mike, great videos however you fail to mention how one actually determines TDC [top-dead-center]. What is it one is looking for? Also it would be great to have a video changing the front fork oil and also removal and reinstall of the gas tank.
Sorry if it wasn't that clear. At TDC the piston will be at the top of the bore. You can feel it stop there for a moment before it starts going down through the plug hole. On the firing stroke (every second rotation) both valves will be closed at TDC and can be adjusted. Regarding the gas tank, my video on changing the air cleaner element includes removing the tank. ruclips.net/video/eJhjIhDqsig/видео.html

Rub a little engine oil on the gasket surfaces to prevent them sticking next time you take them off. Increases their life considerably.

Not done the air filter yet😂
looking forward to a throttle body syncing video :)
A very good Video. Best regards from Germany.
Learned a lot. Thank you Mike. Now I just need to get a Motoguzzi!..........Sal : )

Thank you sir!🇺🇸
Nice video..!!!
You can also check the markings from the timing inspection hole.
Where is the timing inspection hole located on the Breva 750 IE ? And what should the marking look like? Thanks.
I do it the same way (V7 racer 2011)👍

Hi Mike, thank you very much for your videos. Any chance that you can show how to change the gasket between head and cylinder? 🤔
Sorry, probably not. Our Breva doesn't need a top end rebuild anytime soon.
