My nrg 70s only when it has to hold high revs say on a long road a roads etc if i drop the revs the slightest bit after keeping the consistency it will do this loud bellow and when u rev during that time it goes louder then all of a sudden the engine just kicks back in and fires and ur driving down the road then it would just keep doing this process the whole entire road , but when im on short roads this will never happen it is quite hard to explain as i have never dealt with a problem like this and before i start taking everything apart i would like an idea what im looking at i was thinking along the lines of the jetting maybe too small? its a 95jet , cant be spark or ignition cable , cant be throttle , i have a open malossi filter could it be mixture screw too much air? please help lads any input much appreciated!
