Nial Posted February 11, 2021 Report Share Posted February 11, 2021 I have a gas gas txt pro I recently baught and I was told to clean the carb when I got it which I did. I went to put the carb back on and noticed it wouldn’t properly attached to the air box and now the bike isles perfect but when I give it throttle fast it bogs. Is this because there is too much air getting to the carb as the air box won’t attach or do I am have another problem Quote Link to comment Share on other sites More sharing options...
b40rt Posted February 11, 2021 Report Share Posted February 11, 2021 Normally an air leak causes a very fast idle. Quote Link to comment Share on other sites More sharing options...
lineaway Posted February 12, 2021 Report Share Posted February 12, 2021 You did not say what year, what carb. But. yes the carb boot to air box must be attached. Quote Link to comment Share on other sites More sharing options...

peterb Posted February 12, 2021 Report Share Posted February 12, 2021 If the carb is a DellOrto, then at the air inlet end of the carb, there is a cast stub that fits inside the rubber boot that connects the carb to the air filter. There is probably a black rubber sleeve that fits over the carb stub, sometimes, the sleeve gets pushed up into the the rubber boot and the carb is unable to be made air tight at that end. Have a look at this and see if this is the case. A photo would help. Alternatively, if the rubber sleeve is in place on the carb, then it is best to clamp up to this end first, the air inlet side of the carb, before trying to fit the carb to the inlet manifold rubber.

d2w Posted February 13, 2021 Report Share Posted February 13, 2021 In addition to what peterb suggests, use a heat-gun/hair-drier to warm and soften the rubber between the carb and the airbox before pushing the carb outlet into the reed-block input. Basically you're trying to stretch the rubber snorkel. Quote Link to comment Share on other sites More sharing options...
richt Posted February 13, 2021 Report Share Posted February 13, 2021 That's exactly how I do it. Recently modified it and extended the carb inlet with an inch long piece of hose that is a good fit on the carb and snug fit in the air filter duct. So now there is a extra Jubilee clip.
