A mate is running NEDJ (ex RM250) in his 15, 2nd from top and is excellent but our fuel may require slight changes to position, pilot main, from yours.

Float level procedure seems weird until you do it then kinda get a feel for where the float sits , carb on an angle. I cut some cardboard with a slot out of it to set measurement top of float to base of carb. Mine was seriously the other way.

I only had to do a minimum adjustment to the float height. There seems to be no measurements to be had on mine just align the float with the carb body.
The slow jet is blocked & doesn't want to clear (only using nylon to try to clear it as I don't want to damage it). Might just have to get another.
Thanks for the tip on the needle, will probably change it in the future but just need to make sure it runs as well as it did only a couple of weeks ago.
I run it on BP Ultimate (97-99 octane I think).

Check the tank. Only a bit of grit or a hair can prop the float jet open.

Will clean the pilot & the tank as suggested & set the float height.
Don't want to change parts for the sake of it but what needle would be suitable for the future.
Bike only used for racing enduro's, altitide sea level to about 300 metres.
Swazi matt what exactly do you mean by looping the overflow?
Sorry about all the questions, new to Gasgas I usually race a 1980 KDX175 (nice & simple).
have a look at this picture:

Soak the pilot jet in carb cleaner/lacquer thinner/acetone overnight, then blow through with compressed air.
