kinell Posted March 16, 2006 Report Share Posted March 16, 2006 just had my carb off my new beta for the first time today, what a pig to get off.. rear guard off, rear section of exhaust off, airbox and rubber gaitor offcant believe how much 'dirt' has got in the airbox in just two trials and two 'short ' jet washes, looked ok till i got the box out and looked right down in the bottom about a 1/4 inch of silt hiding down there. rubber boot to carb was also a hiding place for the stuff little or none at entrance to carb and none at all in carb. question is though... there are 3 exits for excess fuel and only the overflow actually has a tube on it should the other two ( the one on the nearside of the carb and the one underneath?) <{POST_SNAPBACK}> There is a knack to getting the carb back on but getting it off should be easy enough, even on a new bike with stiff rubbers. Is there a foam/rubber tube type seal underneath the airbox lid? I once forgot to replace the foam when I fitted a new rear guard and found that the filter got very mucky without it. Also, if you have removed the wiring for the rear light - don't forget to silicone the 1/2" hole up properly. This will stop all the **** from the back tyre being thrown up and onto the filter. There is a thread somewhere on here with photo's of a drain pipe setup for the airbox if you can find it... As far as the exits go, the brass tubes on the left and right sides of the carb are vent pipes to allow air IN as the fuel goes OUT. I think the bottom pipe is the actual overflow for the carb. Fuel can leak out of the side pipes quite easily. Somebody (BillyT?) suggested connecting the vent on the exhaust side directly to the pipe underneath the carb. The vent near to the choke lever is capable of sucking enough air in to the carb to prevent a vacuum. Quote Link to comment Share on other sites More sharing options...
bob Posted March 16, 2006 Report Share Posted March 16, 2006 actually i think that it was billy T who strongly suggested not to connext the exhaust side tube to the overflow as that would mean that rather than petrol flowing out of your carb onto the floor/crankcase, it will just fill up your engine, i actually run mine without a tube on the bottom overflow without any problems, i just drain my carb after every wash, and it's ran fine for ages.

kinell Posted March 16, 2006 Report Share Posted March 16, 2006 Aye, mebbe you're right - I can't remember I tried it on an 02 Beta and it worked fine until the middle box melted the tube and sealed it up. Ran like a mangy dog because of the vacuum effect thingy... Quote Link to comment Share on other sites More sharing options...
