Excellent video, I have 10k still to do before this service, but having watched your video I'd feel pretty confident, thanks man ✌
@bettajetta15 Před měsícem

@mw8151 Před 2 měsíci
I now know why I am trusting an expert with this😅 I think Ill dtart small… with changing oil😂
@xrotor7813 Před 2 měsíci
Thanks for the video - How did you decide in advance to replace the timing chain or is it just your normal practise?
@lukep77 Před 2 měsíci
It's definitely not required to replace the timing chain at 26k miles, but I thought mine had gotten stretched out so I decided to replace it while I had the engine open. It turned out that there was no noticeable stretching between my old chain and new chain.

I am doing the same task and your video was extremely helpful. I have a question about the marks (lines) between the two timing gears. Were they exactly parallel at top dead center or did they have a slight deviation? It's my dilemma as I didn't get a new chain. The deviation is so small that it certainly won't cause me a problem right away (it will definitely have to be replaced in the future). On the other hand, if with the new chain they were perfectly aligned, I think it's worth it to replace it now that the bike has been dismantled to put a new one. I have 24.000 on clock (about 20.000 miles)
@lukep77 Před 5 měsíci
I don’t really remember if the lines were parallel or not with my original chain but I assume they were. If you’re skeptical about it id definitely recommend just replacing it.
@stefan_munchner Před 5 měsíci
@@lukep77Thank you very much for the prompt reply. I have tried 4 or 5 times and my chain jumps 1 or 2 peaks on the cog. This is confusing me and I can't figure out if the chain needs to be changed. I will try again today when I am rested and have a clear mind. Thank you again.

That's way above my pay grade 😂 Well done!

Great vid mate, love the WRR tech stuff, appreciate it! Coming up to 10K miles on mine :)
@bravo_victor Před 9 měsíci
Man, this is so freaking helpful. I daily a '14 WR250R coming up on 28K miles, and I've been putting off the valve check and a cam chain/tensioner mostly because I couldn't find anything online. I do my own work, but fooling with the engine using only the service manual is a real challenge. Ordering the rest of these parts and will set aside a Saturday soon to knock it all out. Really appreciate the time you took making this.
@lukep77 Před 9 měsíci
So glad I could help! Best of luck, hope it goes smooth! If you’re also planning on changing the timing chain, I compared my old chain to new one and there was actually zero stretch in the chain after 26k miles of pretty hard riding. So its not necessary to do and will save alot of time if you don’t feel the need to do it. Don’t blame you though if you wanna change it regardless just in case.
@bravo_victor Před 9 měsíci
@@lukep77 Good to know, I've been leaning towards changing the tensioner, checking the valves, and leaving everything else as-is for now. Thanks!
@mcgo3595 Před 19 dny

Were you getting cold start cam chain rattle/clanking ? Really appreciate that you took the time to do this! Excellent job.
@lukep77 Před 10 měsíci
Thanks! I was getting a little bit of rattle when I started the engine but it went away after a few seconds.
