Reply To: GV250 Won’t run after carbs serviced!
Because the carb has orings inside the throttle shaft, choke plunger, valve float seats, there were extra freebies incase you did a total disassemble of the carb to pieces!
In this case, you can just keep them as spares for future. I just throw in as much as i can in the gasket kits.
They look good! They don’t need orings those Size 20 Pilot Jets. Just a very clean hole, as by now you have seen how tiny the center hole is!
(Sorry we can’t use more than Size 20 pilots as even size 25 will make it run very rough and too rich.)
Size 20 will do for now 🙂
“Starting Jet” = Permanent. Must be air compressor as hard as possible as the that permanent jet has an even smaller hole then the pilots.
Funny enough, it is also needed when the bike is running, as heaven forbid the bike stalls mid-way through a journey, it will help you start, it reaches furthest in the float bowl, also has an exit on the sides of it (deep inside the carb)
Here’s a hint,
Get carb cleaner & attach a straw to it (they usually come with one)
Spray inside the “Starting Jet” , you will actually see the carb cleaner squirt out of it deep inside the carb’s silver walls where the “Starting Jet” sits on. Hard to visualize , i know but it will make sense when you try it.
Then you know the starting Jet is not clogged anymore!
Oh I forgot to mention that revs didn’t change and engine stopped as soon as throttle touched – not surprising with only one cyl going! Fuel. I have no idea what E5 fuel means. Here in Spain it’s 95 unleaded or 98 octane I use 95
Use RON98 , the more premium the better 🙂
E5 (97+ octane) petrol.
Here we have changed from RONS to E’s , so its either E10 (which the hyos hate, old cars hate it, some injected bikes/cars have a love & hate relationship with it)
or we use E5
