gilera dna 50... 2 stroke trouble

[ART-ADS]

having issues with my gilera dna 50 2 stroke, it revs up fine on the stand but when I'm riding it to get it into the powerband (7.000 rpm+) I need to almost pump the fuel in my blipping the throttle back and forth pretty quick, sometimes raggin the thing but when it hits the 7,000 its fine and pulls as it should. the little 50 hits a genuine 50mph on the flat so It really needs to be tuned well to get that sort of speed out of the wee motor, which is why I suspect there are a couple issues, but also I don't recall it used to be like that so I don't know proper stuck

I pulled the carb off and cleaned it out (it was already very clean) and it didn't seem to do anything besides stop it from working lol, it would rev up on the stand but when on the road it'd lose power and basically keep going into lulls, after f**kin with it some more I got it back to how it was but still I have the pumping problem

any advice plz

1. Check air intake - No splits in the rubber from the airbox to the carb - clean air filter.

2. Check throttle needle setting is correct.

3. Check float level correct.

4. Check the fuel filter is clean.

5. Check spark plug and HT lead connection.

6. Ensure mixture screw is set correctly.

7. Check two-stroke oil / fuel mix is correct.

Not a lot else can go wrong with this engine.

Exhaust clean?

The inside not the outside BTW.

2 strokes are fussy about exhaust back pressures.
