Yamaha XJ 750 (41Y) engine project, part 1, top end disassembly

[@Potatogamer_smii7ylover]

I like the commentary, definitely helps a lot. I’m taking apart the xj650 right now.

[@wildandbarefoot]

One of the best engines ever made.

Voiceover is fine! 😊

I'm hoping that I'll find time to revisit the 41Y project soon If you been waiting for the next episode, I can tell you the you haven't missed anything, the project has been standing still since I made this first episode almost 1½ year ago

Very helpful about to take apart my xj700. I like the angle.

[@XJ_doc]

Thanks mate. Then it is unfortunate that I haven't have the time to disable the bottom end yet.

I’m preparing to strip a 1991 XJ900F engine and your videos will prove invaluable! Look forward to seeing the rest, and the rebuild if you are going to video that.

[@XJ_doc]

That's my plan But at the moment I think you are going to wait a little while, as I have promised to do some work for others, and that just comes first But as said, it is my plan to document the whole process, incl upgrading the 750 to 850

[@tribsa7503]

@@XJ_doc Well, I’m quite a way off too. At the moment I’m concentrating on the frame and the wire wheel conversion!

[@tribsa7503]

Hi. Yes I have started pulling my 1991 XJ909F apart. I’ve ditched the fairing, loads of fittings and cut the rear frame loop off. I’ve just had two XVS650 Dragstar wire wheel rear hubs converted to take extra 17mm inside diameter bearings. I say two, because I’ve acquired a 1990 XJ as well! Lots to do, and I’ll start a video soon. The thing is these projects take quite a while, so there may be a gap between video posts. I think it’s going to be an interesting project, and judging by the amount of money I’m spending, expensive!

Hej! Fed video! Har i fredags skiftet toppakning ved hjælp af din video, og det hjalp! Men nu kommer det store spørgsmål. Ved du, om 750 seca kom med 4 gear?’min Yamaha xj750 Seca har nemlig kun 4.

Hi Erik thanks for the video, I'm planning on doing this to check how my valves are, and clean up/change head gasket on my xj750rh. Is it possible to do this from the bike on center stand? Maybe secured with weights or something? I don't have any lift and I'm on my own, also my shims are way off right now, dummy question but should I change them after valve lapping and rebuild to check clearance again? Or should I do it before? I know it's kinda stupid but since I'm not sure if it matters I'd rather ask!

[@Scropion2027]

Was there are part 2/3/4?

[@XJ_doc]

They are planned, but life has gotten in the way, so currently the project is paused But I want to continue the project, hopefully the upcoming winter

[@JayTolbert-x3v]
