Before I take anything apart I will check on my clutch actuation adjustment (under the plastic side cover).
The problem got worse since I swapped to higher bars ...the clutch cable will be swapped to a longer one so I guess this could cause the clutch to drag sometimes (too short clutch cable).

The gas cable is way too short and causes the bike to gas when I turn left or right the tightely :-) pretty funny when you pull up to your friends and the bike revv´s up like hell when the bike is parked  :D

So guys!

Great news on the XS front.

The "cracking" gears stopped after I readjusted the clutch actuation screw.One turn out and it got WAY better

Had my friend "Der Nanno" coming over redadjusting the valves ( they were set completely wrong), readjusting the ignition and syncing the carbs.Now the baby starts first kick even when the engine is cold.

Since I swapped to higher bars I had to order new bowdens for gas and clutch and currently waiting for them.
Bike is supercomfy now with the new bars.

I have the plan to ride with this bike to my Bachelorparty in Zagreb (Croatia) this summer, so it has to work properly or I will strand somewhere  ::)

One thing I still need to do is dropping the needle clip, it looks like the bike is running a bit lean in the mid throttle area.
I already took the needles out but there is a plastic piece (maybe its a shim) in there which I cant really eyeball what to do with it.
Under the plastic piece there are still 2 notches to adjust the needle so maybe I just need to take that out...

What are your thoughts on these?

Simply adjust the needle as you would on the RD, the plastic bobbin is just a retainer (of sorts) and will not affect jetting.

Cheers,
Greg

So guys,not a lot of time to wrench on the stock Xs750 the last days but I ride her nearly every day and I´m really happy with her. The rear brake master cylinder needs an overhaul, will sort that out in the course of the summer.

While I was busy ridind the XS 750 I started dissassembling the other motor I have in my XS cafe racer project.

The top end of the bike was just "stuck" on the bike, all the nuts and bolts were loose.
When I removed the engine from the frame I removed the oil sump, didn´t find any major damages or whatnot,gears seem to be in good condition.

The plan now is the break the engine open till I reach the crank, the PO told me that the crank was somehow not "in good condition".
First thing will be checking if the crank seats are stock or damaged or anything.


Did you guys measure your cranks with plastigauge?

Thanks

Yep. Oh and btw. I have a spare rear mastercylinder-repair-kit, if you want.
