Back to the carburettor work—it looks brand new now. Feels great.
This time, thankfully the float valve area is new!
Future task: I need to adapt the old metal or tin valve here to a modern rubber one. Since Decoboco doesn’t have many GR71 customers yet, I’m not fired up about it.
Parts like this can be polished and reused if they’re only slightly stepped. *Only the ones with light scratches, mind you.
This is hard to see in the photo, but when I screw down the float valve seat, you can see it tilts to the right.
Cylinders 1–3 are fine, but only number 4 tilts. It should be okay, but I’d rather do the work now than regret it later.
I ground 0.2 mm, then 0.2 mm again, repeating until it was straight.
Marking the accelerator pump discharge direction with a marker makes adjustment easier.
According to the manual: “Start the engine and check the fuel level.”
Pretty vague, right? Straddling it? On the sidestand? On a racing stand?
Well, I’ll take it as a reference.
The current FL value and
I adjusted from the current actual fuel level.
This time it’s a “let’s go full power!” plan. The jets are already changed. The air filter is different too, but… I’m not sure? Same?
The inner tube length is different. This looks good.
I installed it and balanced the carburetors.
