I've been totally consistent with that argument. You can instrument all sorts of things and detect minute differences. But subjective experiences are just too unreliable, and vastly more "coarse". I stick with what I said and offer a challenge: there's no way you - the rider - can feel a difference from adjusting the valve clearances, unless they are so far out you've lost compression or can hear the clatter. I'd be very happy to conduct a single- or double-blind experiment with anyone here who believes they can feel a 0.05mm difference in valve clearance. Let's put it to a real test. There are so many people on the internet who assert rubbish about how their bike "feels smoother" after fitting a new bulb in the back light, or "accelerates better" after topping up the fork oil (I made both of these up, but you know what I mean). It's all bullshit. The only data that counts is instrumented, objective data. Subjective data is so unreliable it's no use at all for making real decisions. 3 Link to post
Tex 36,817 Posted July 28, 2018 Share Posted July 28, 2018 Back when engines were cursed with carburettors properly balancing them would make an appreciable difference (still does on classic bikes/cars) but other than that I agree, Steve. Nothing else on a routine service will make a haporth of difference. 2 Link to post

Actually, there is one thing that's kind of half a joke and half has a point: the cheapest way to make the bike faster is to lubricate the throttle cable. One of my lecturers swears by it. In any case, it underlines how unreliable subjective impressions are. Link to post
Tex 36,817 Posted July 28, 2018 Share Posted July 28, 2018 Ha! My old workshop foreman impressed upon me the need to clean a car’s windscreen on completion of a service - made them faster too, apparently. Link to post
temp 359 Posted July 28, 2018 Share Posted July 28, 2018 My Hondas have never had the valve clearances checked since I had them, because: 1. I don't want to pay loads of money to someone who may or not do the job properly🤔🤑; 2. I'm likely to make things worse if I do it myself (though my old Ladas survived my attentions until they met the scrapyard😬); 3. I haven't notice any loss of performance, but we may be aging at a similar rate😕; 4. They are Hondas😀. 2 Link to post
alhendo1 3,053 Posted July 28, 2018 Author Share Posted July 28, 2018 (edited) I'd planned on keeping this bike for 2 or 3 years so I'll probably never do the valve clearances either....but you never can tell....that being said....I can possibly see a T100 in the future....I may have missed a trick there. ...but I'm not taking a serious financial hit just yet😅 If the vibration thing cant/won't be sorted I'll take mitigating action and make it bearable. ...bar brace etc...I really like the CB....

Which kind of reminds me of the dipstick on my 'slant 4' 2.3 SOHC Vauxhall engine, it had separate air filters for the carbs, rather than the old combined airbox filter housing, so the cam cover breather had nowhere to vent to, i was contemplating what to do about it and with the engine running blanked it off, all ways well for a few seconds when there was bang and the dipstick went skywards at a rate of knots, I recovered it from the middle of the front garden, with a rather bemused look on my face according to my Father! 3 Link to post

He decided to check the oil and couldn't find the DIPSTICK (its a glass window on this bike) So he picked up a brittle stick and shoved it in the filler hole and dropped it in the sump . !! 1 1 Link to post
Rocker66 34,466 Posted July 29, 2018 Share Posted July 29, 2018 Years ago we were all waiting in the Sunshine Cafe for a friend called Tony to arrive on his Velo. When he didn’t arrive we went to his home. When we got there we saw him with the top end off his engine and a garden hose pouring water into the crankcase. Apparently when working on the engine he had used the old trick of putting rag into the mouth of the crankcase to prevent anything falling in. In his rush to finish the rebuild he forgot to remove all the rag resulting small bits of material circulating the engine when it was started up. He was trying to flush it out. To this day he has not been allowed to forget it. If only we had had phone cameras and YouTube in those days😀😀 1 1 Link to post

Trev 18,740 Posted July 31, 2018 Share Posted July 31, 2018 Did the right hand side of my Guzzi V7 last night. Started by trying to make sense of the fair bit of conflicting info out there (as usual) on what the gaps might be, I just went with the manual in the end although, apparently that's not always best with Guzzis? Propped bike on side stand and piece of wood and clicked it into top gear and removed spark plugs so I could find top of compression stroke with a paper straw. Rocker cover came off nae problem, both inlet and exhaust felt a wee bit tight, exhaust a bit more so than the inlet. After twenty minutes of loosening and retightening the buggers I've ended up with both a tiny bit less tight I think, maybe, just about, not blinkin worth it! All back to together, both plugs in, out of gear and it fired up fine and sounded the same as it did before, no surpise. Tonight I'll check the left hand side but, unless significantly out, I won't faff about adjsutung but will leave as is. Unlike me, please remember the manual states 'valve clearance check' not 'valve clearance adjust' for a reason, they very likely won't need adjusting so don't waste time and effort trying to improve the tolerance by half a gnats wotsit 1 1 Link to post
Andy m 23,587 Posted July 31, 2018 Share Posted July 31, 2018 (edited) You need one of these Pooratrek do them in kit form for a few quid 😗😗😚🤔, you just need to supply the hammer and do the drilling. So long as they have a gap when closed and don't clatter when running they'll be fine. Adjusting to the nearest micron/gnats cock hair wears the adjusters more than just leaving them for another 10000 miles. Andy Edited July 31, 2018 by Andy m 1 Link to post

When checking the valve clearances, if a feeler of the smaller dimension passes freely, and a feeler of the larger dimension either won't pass or passes stiffly, the clearances are fine. All this stuff about trying to get a sliding fit for a feeler of the "nominal" dimension is largely a waste of time, although some people think setting the gap as close to nominal as possible will give the longest time before adjustment is needed. In reality it depends on the engine. Some recess the valves over time, so the gaps gradually get smaller. Others wear the valve train (especially old pushrod engines) so the gaps get bigger. Knowing the engine might inform you as to whether to adjust towards the upper or lower end of the clearance range. Link to post

I thought odd that the Guzzi manual only has one specific measurement for each. I checked the manual for the last bike I did valve clearnaces on, SUzuki GSXR1100, and that tolerances as expected. I need to do the Griso somewhen so will try to make sure I have correct info on tolerances for that before I start. Link to post

Andy m 23,587 Posted July 31, 2018 Share Posted July 31, 2018 The Guzzi has a single injector in this incarnation so balance issues would only be caused by leaks. When they went to FI they initially had two which was almost as bad a carbs. Andy Link to post
