      I have a GV250 Aquila put new needle valve in carbs. I was getting gas in oil new needle valves seem to have stopped that. Now it idles good starts great just will not get up to speed or rpms in gear. slow response from throttle in gear. after 3rd gear it will not maintain what speed it gets to. good compression ran great before new needles put in carbs. any help would be great.

      what size are the main jets ?

      Have the slide needles been altered (it has 3 settings = richer (best) , factory , lean (bad) ?

      Are the slides sicky (check they might not be lifting or retracting properly to allow the main jets to give out the fuel needed for power

      What size are the “pilot jets” and “main jets” on the bike ? let us know

      Also look at the spark plugs  (get fresh cr8e first) , go for a short ride if possible, pull them out and take loads of pictures to show us.

      slide needles are at factory settings. factory jets, slide were moving smoothly will double check them will do plugs after checking slides.

      slides moving smoothly noticed one of the boots from carb to airbox was pushed up into airbox could that have caused the problem.

      Yes as you may lose intake pressure or introduce unwanted air leaks , since we can’t see how bad it is, i am only assuming here for now.

      Got it back together and it runs great except for the idle goes from 1500 to 3000 after putting it in gear. I can turn bike off for around 90 seconds and it goes back to 1500. I can let it idle for about 30 mins. it will stay at 1500 once it warms up intel I go to ride it.

      Your intake rings are on the way aren’t they , they could help the situation as any “rev changes” while the bike is idling OR moving = Intake pipes , intake o-rings , airbox

      There is 2x tutorials on the forum on how to remove and refit the GV125 airbox  (it is the same part used on GV250) , use them as guides on how to reassemble correctly , I know how tight that space is , i work on Aquilas all the time.
