could anyone explain to me how to open up a stock gurtner carb jet? I'm not even sure where to find it on this carb. want to open it up a little to see if I can't at least get another 5mph out of my peugeot.

just having a bigger jet isnt going to give you any more speed.
well from all my research so far, it seems that it is suppose to. But, I have to say, with everything being stock as it is and it only being rated to go 25 mph, I have the thing doing about 35 mph now. I wouldn't mind getting it up to 40 or 45.
the upjet is just going to give you more gas to the cylinder. but, if there are no upgrades to use that extra fuel, its just going to cause a fuel rich condition, and cause performance to suffer. if you put in the expansion exhaust, along with a bigger jet, that will be the biggest performance upgrade you can do, short of kitting the moped.
please show the research that you did which denotes a performance increase from an upjet without other modification..
Just altering the jetting on my motorcycle took the top speed from 115mph to 122mph.
That is common on bikes that had to pass emissions regulations. I can't say it's normal for mopeds, but 2 strokes are highly sensitive to ambiant conditions.
I think what the OP needs to think about is "proper" jetting, not just "bigger" jetting.
has the OP done plug chops yet?
