- The engine is finally apart. The rattle was from the primary chain which has stretched to the point where it was rubbing on the oil nozzle. New parts to be ordered and next step is to give this engine a really good clean.
Gday, definitely lots of bit when you multiply everything by 3, this project is coming along beautifully, thanks for the updates
been watch'en this bike build .. I am so ENJOYING !! Thanks man..
Thanks mate
That's really cool dude
Thanks mate
Hi from Kathmandu nepal
hey mate! howd you take the rotor off so easily at 00:35? i cant seem to take it off without it spinning. they dont see the holder tools anymore
Just like the video shows, i used an impact driver. Without that it will probably turn as you say....The primary chain should stop it turning
Breaking my 650 down from the bottom.
Just can not shift the cylinder head one bit. And my fins are ALL good so Im not whacking.
Corners didnt work.
Hi mate, yep it can be tight. Junk seems to get in between the head bolts and the hole. Try some WD40 or light heat. Patience will get you there.
@@Mezzmoengineering Appreciate the reply and great work on the bike well done.
Making your own bearings on a lathe is close to Jesus.
I'm working on a pallet in the driveway.
Can 4 of WD40 re; cyl head.
Its some craic this.
@@clickireland1113 OK, is the head itself stuck or the barrel? if its the head, have you removed all the nuts around the base of the head? One of the engines I had was very tight too, ending up using a hammer but only because it was a barrel from the 650 that I wasn't going to use.
@@Mezzmoengineering Yip, Head itself. All nuts out and Ive checked nine times.
I'll figure it + gravity.
@@Mezzmoengineering Should seen what I had to do get the stator out.
Corrosion stuck it in and hadda wreck it out. Fifty bucks anyways but I busted the AC gen too so here we go.
Where did you get all these parts?, i have an XJ750 Seca and I would like to change some old parts for better ones!
Hi mate, just from lots of searching. Some on ebay, some private sales and some from Yamaha directly. Check the CSML site has they have lots of gear too.
I am reassembling the same motor - did you remove/replace the bearing in the crankcase - the one in a `blind` recess - end of gearshaft?
Not sure which one you mean, what time in the video is it?
Nice job.
Q: The little notches on the gear cogs (present on 5th and the gear cog next to it) : I see them same kinda notches on the same cogs in your engine in this video.
This fork wear?
And should I replace the cogs because of the wee notches?
THanks
Hi Mate, No they are fine. I think that are made that way to aid lubrication. Check pics online as they all have them. One of my engines was low miles and it was the one in the video. These transmissions are bullet proof. I checked my manual but can't see a clear pic of the notches to check its like that from new...
@@Mezzmoengineering Class to know that.
Going well anyways.
Just saw a neat vid on how to pop the AC Generator off.
Wouldn't ya know; An Aussie :)

Thanks again I'm off to try this.
13.23Hrs here. I'm running on greenhouse lettuce.
So the xj750 head will straight swap over to an xj650 without any modifications, my 650 head has numerous broke or screwed up intake bolt holes so Im thinking just pickin up a 750 head and swappin over my 650 pieces, cams etc.
Hi mate, well it did on mine. I don't know if particular XJ650 and XJ750 years don't differ in some way. You will need to have matching barrels for either YICS or non YICS though
What does the tool too pull the Genarater out the casing
Hi Chad, from memory there is a thread in the end of the rotor. I think it might be 15 or 16mm. You screw it in and it will bottom inside the shaft. Put some tension on it and tap with hammer and it should come off.
@@Mezzmoengineering thanks got it off just struggling to get the ring gear out
hi mate how mutch slack was on new chain when you got it in.
Hi mate, very little slack with the new chain. Was a perfect fit, I did use a genuine chain as well as replacing the guide.
@@Mezzmoengineering cheers mine got bit slack in and thinking if i should strip bottom end wile engine out. as barrels are off. that chain not cheap at 126 uk pounds
@@thehutx my old chain was so slack that it caused the chain lube pin to wear down significantly. If your chain is slack enough to allow it to hit that oiler then its time to replace it. You can see that oiler in my video. If you're still 4 or 5mm away from the oiler pin then it should be good for a while longer
@Mezzmoengineering not sure if I can see it from in sump. Not sure how far it be off it
@@thehutx Yeah, you might not be able to see it. I guess you can just go by the sound as you will clearly hear a rattle at idle if its badly stretched
