If you want to do the job right,balance the intake throttles just after. The valve lift is modified when you adjust the valves,so the cylinders do not work evenly anymore,one is pulling more air than the others.

Sir you are my hero!!! Compressing the spring” no problem” but removing the shim- even with a professional dental pick, no fun. Compressed air!!! Brava Brava!
@michaelovitch4 жыл бұрын
Thanks, The thin layer of oil between the bucket and the shim creates suction,so using a tool is rarely efficient to pull the shim. Air will push the oil and circulate easily between both,specially if you aim at the slits in the bucket, designed for the tool to grab in : it's a direct path under for air : )

Do you grind the correct side of the plate? In my opinion, the valve side was better. Why the camshaft should work on a ground surface?
@michaelovitch5 жыл бұрын
I ground the side wich do not touch the camshaft lobe. You keep the smooth side for the cam lobe,so no wear occur on both parts cam and shim,not knowing if it's surface hardened or deeply hardened. You are supposed to have a constant oil film on the shim,so both parts are protected,but on the long term use,smother is better to begin with : )

will do balance, have done drive shaft splines. It seems to be the only bike ideally suited for bypass oil filter, that is water cooled single plate dry clutch, hopefully someone will correct me if im wrong, but i dont know of any others.
@michaelovitch7 жыл бұрын
There are a lot bmw ,moto guzzi ,ural too i think ,with a single plate dry clutch wich are air ,or watercooled engines. generally the gearbox is inline with the engine,there is more room for a single ,bigger plate clutch.
@julie69247 жыл бұрын
From what i can gather bypass filter can extend oil change intervals but when air cooled due to extra heat. im thinking these k's may be the only bikes as durable as a car because built like a manual car, single dry clutch, water cooled, (and drive shaft.) Some ducattis but multi plate i think.
@julie69247 жыл бұрын
(meant to say but not air cooled)
@michaelovitch7 жыл бұрын
Unless the filter media can retain smaller partcles than the stock one in place on the bike,there is no point using an additional by pass filter. As i know you can extend oil intervals if the oil do not suffer from excessive heat (above 90 °C is starting to be bad) or if you not have fuel dilution,wich mean an engine running not often rich,or cold. Like you say,oil cooled engines or air cooled engines are not the best for oil extended life... For conventional oil it's one year max or the mileage given by the bike manufacturer. Two years for synthetic oil max,or the mileage given by the bike manufacturer. On my k75 i'm on a very cheap oil,for now,and i will switch on a 5w40 low budget synthetic. it's a ACEA A3 B4 norm, an engine oil for cars. I have a 20w50 oil with an oil thickener in my car,just to see what it's doing. I have 5 bars of oil pressure cold at idle ,and 2 bars at 80°C at idle,wich rise at 4.5 bars as soon i blip the throttle....
@julie69247 жыл бұрын
it has worked well for me on a previous car using a toilet roll filter, im thinking you can extend oil changes by km instead of time since it also absorbs condensation which stops it combining with sulfur to form acid. Anyway your videos are brilliant, they show much more than the books and saves a lot of time

michaelovitch intake. Sorry for the confusion. I tried using the gap clearance on the intake and the only clearance I get was 13mm max. I mesure the thickness of my shim and it reads 2.55mm. I went to the stores and got some shims for the intake and they are 2.30mm thick. I put them on and the intake gap clearance is now at 25mm. Would it give me any problems since the intake clearance is at a 25mm? When the manual says 15mm through 20mm for intake.
@michaelovitch4 жыл бұрын
@@isofly28 25/100 is ok. The more clearance you have,the less the valve will open,so the less your engine is sucking air. If you have too much clearance,the engine will be noisy.

If you park it on the side stand before to shut off the engine and let the oil flow back down,yes,a bit : ) otherwise,no just think at all the Porsche ,Corvair,falt twin bmw ,flat 6 engines etc... : )

michaelovitch that's what i was told a friend had an old one and he said his would burn oil everytime he parked is it unavoidable even with new piston rings?
@michaelovitch7 жыл бұрын
Even brand new piston rings do not really seal when the engine is not running,whatever the engine type,as long as the oil film on the cylinder is not present. They do not expand since there is no pressure from the combustion applied on them and no heat to expand metals (cylinder and piston/rings) So you wil maybe reduce the leak through them if the old rings were used a lot,but it's really minimal. If you have a good compression on the engine,no need to replace them. It's just a "problem" of conception. you can use a thicker oil,or just use the central stand lol

Absolutely! Besides not being able to get a perfectly flat and parallel surface, it’s very easy to overheat the shim grinding it in this fashion. Better to buy a new shim and put that one aside for when you need that size for one of the other valves.
