I did the service of my bike. I also had drain the timing chest unscrewing the quill bolt. Whit that I also check for the worm seal. That is the steps i did:
- I turned the bike on and let it heat for a few minutes, so that the oil went to temperature and flowed more easily;
- Bowing under the bike, I found 3 bolts: two equipped with a metallic retina filter and one, central no. I opened them one at a time individually, causing the oil to flow;
- Waiting a while, I then opened the valve on the side of the distribution, the one with the "syringe" that enters the seal (quill seal);
- I opened the oil filter compartment, paying attention to the order of the pieces, stacking everything in an electrician band in order not to lose the sequence;
- I removed the spark and I push the kickstart a few times to let out more oil, then I inclined the bike for a while, first on the left and then on the right;
- (IRONIA MODE ON - I did this I did the mystical dance in the round to the bike for 3 times, the first clockwise, then counterclockwise and again, please be careful that the dance must be done at 12.00 o'clock - IRONIA MODE OFF );
- I cleaned and dried the various pieces disassembled, putting a new oil filter in a glass filled with engine oil;
- With a little compressed air (in can) I verified that the oil hole at the base of the screw housing (distribution side) was free. Spraying in air, venting from the filter compartment;
- After this I checked the seal (quill seal) distribution side (you can see the attached photos). It seems in good condition. For safety I have a spare part if needed in the future;
- At this point I inserted the new gaskets and oil filter and I tightened everything;
- I opened the inspection compartment of the rods and I poured in about 200 ml of engine oil and then topped up the oil in the appropriate hole;
- I again kickstart and also having the bike on the center stand, I meshed a high gear and I turned the wheel, so that the pump is activated and sent in circulation a bit of oil, so as to run the lubricated engine immediately;
- I turned the bike on, taking care to listen carefully for any strange noises;
- As I am paranoid, I loosened quill bolt on the distribution side a little to make sure that oil arrived;
- Same thing has been done for the Banjo Bolt who bring oil to the rockers. If they are not completely unscrewed they only make a few drops of oil. I have been told that you can check that oil arrives to the rocker arms even inspecting the inspection cover of the rods: if you see the oil go down it means that everything is fine. I honestly did it and it's not that I see all this waterfall of oil.
Nearly 2 liters of oil (1.7 liters ) came in against 2.25 liters, reaching almost the maximum of the notch.
That done I checked the oil in the primary distribution. I opened the valve at the top and unscrewed the bottom one (a bolt with a split notch) to check the level. If a little oil comes out, the level is correct. The color was clear and did not present metal filings, so I opted to leave what is there.
Finally I gave a new clean to the bike, checked that all the screws were tightened and passed some greasing point.

https://we.tl/GxyrT0NzIpAfter all I take a tour for checking all was ok. I drove my bike around the neighborhood for about 15 minutes. After I was checking the oil and it was at low level, so I did a refill of amo the 200 ml of oil for a total of 2.0 liters... is this normal, that the oil go down so soon?
