So far so good.

Used 4 hands and 2 jacks to get the engine back to its home:

Maybe use the gear sensor to install a non rpm gear indicator.

I got the engine in.

- all coolant hoses fit.
- all coolant steel connections fit
- all intake rubbers fit
- all spark plug cables fit they are different spark plugs but, the cables fit
- EOP fits
- ECT fits
- CKP fits
- alternator not sure but, it came without one so put the old one over
- all coolant gasket fits
- starter fits
- TB fits
- clutch cable fits
- AIS fits
- exhaust fits
- VSS fits
- engine hangers fit

Need to redo:

- Neutral switch (2019 does have gear indicator) wiring only redo (LG wire)
- gear shifter stabiliser

Engine starts, Missing clutch and housing does the old type fit?
Both SHOULD fit, color seems to be the only difference. But at that mileage there should be fairly significant wear in the basket and plates, you may want to replace with a used basket.

It has a clutch inside but, it rattles. Only 3250mls/5000km

Great progression. Is there a list of "no fits?

After changing my original chain (surprise, metal part of my tie down strap wasn’t popular when it went through) I would have no issue using a 520. I think the 525 is over engineered especially when using traction control. After measuring the stretch on the original chain, it was less than 1/4 inch for over 20k km of distance, but to each their own. I’ve really enjoyed your build and updates!

Ok, kind of what figured. I see there is a middle mounting point otherwise they’d put a lot of strain on the handlebars and they’d bend fairly easily depending on the bar. So you chose to run them? Kind of a “slider” thing I bet.

What they looked like in my head are something you’d use if you wanted to do crowd control, like in a zombie or Max Max futuristic style of movie, lol!!!
Crowd Control!! hahahaha

What rpm are you sitting at when going 65 mph/105kph? I want the quicker accel with different sprockets, I don’t care to have a high top speed, but I also don’t want to ruin my fuel consumption due to higher engine rpm when cruising
