Thank you

Thanks

The reason for it is to make sure any water that gets into the spark plug hole can drain away Thanks for watching

​@@motorcyclefixeroh that is cery interesting. I habe first panicted but was relieved as i saw, that it is by factory and now i know for what it was drilled. Thank you very much 4 your Quick answer👍

have you taken the cam chain tensioner out? if you take it out you should have enough slack

I'm not sure on the miles sorry The guy I bought it off swapped it out as the output shaft was ruined

Hi I don't have any experience with that model but that amount of vibration isn't normal If it's at a standstill then it could be an internal engine bearing

Yes I cover it in one of the videos I believe it's the bottom end rebuild video. Basically you need to turn the crank until its at top dead centre. Use a long ball ended Allen key in the spark plug hole then there is a small bolt on the side of the bottom casing that you remove and put a pointed grub screw in the hole which locks the crank at top dead centre

How do you know if it’s in compression TDC or exhaust TDC or it doesn’t matter?

@@mrsvetly it depends what you're doing but if the valves are closed it's the compression stroke If you're setting the timing and you have the cam chain off then it doesn't matter because you'll set the valves closed The spark fires on both strokes

@@motorcyclefixer i am asking because I was trying to check the valves and forgot to put the bike in TDC and the chain tensioner so when I turned the engine the chain skipped and the cams rotated so I had no idea where was I. But I put a screw driver through the spark plug hole on cyl 1 to try and find TDC and stopped when it stopped moving up, so I thought I was in TDC. But when I started the engine after reassembly it was making all those clapping noises and I shut it off immediately. You think I bent any valves/pistons? Any idea why my plan didn’t work?

@@mrsvetly I think the best thing to do is to get your hands on a manual and work through it. It's hard to diagnose it without looking at it tbh if you've done it correctly and there's still a mouse though then it'll be something else Maybe a big end bearing or something else Have you checked the valve clearances

It should always have an arrow on it when it's new. you can however look at the cut-outs for the valves. bigger cut-out in the piston goes with the bigger valves. the intake valves are normally the biggest so the bigger cut-outs go to the back

@motorcyclefixer This piston doesn't have valve marks, only have the size of the piston (B and 99,98)
