betadad Posted October 20, 2008 Report Share Posted October 20, 2008 Hi, when starting the bike from cold (with choke), it starts first kick, but the revs shoot up, I have to immediately take the choke Off, and blip the throttle a couple of times and the revs slowly settle down. There are no mechanical linkage problems (throttle cable) the the carb is clean. Anyone out there help me? Quote Link to comment Share on other sites More sharing options...

big john Posted October 20, 2008 Report Share Posted October 20, 2008 Yes, this is quite normal for the 125 Beta using the Dellorto carb. We had one (an 06), it is quite un-nerving at the start as you think the throttle has jammed. Big John Quote Link to comment Share on other sites More sharing options...
g14gav Posted October 20, 2008 Report Share Posted October 20, 2008 This happened to one of my gasgas`s and I found it had a tiny hole in the rubber inlet inbetween the carb and the barrel. May not help but would eliminate that at least. G14 Quote Link to comment Share on other sites More sharing options...

copemech Posted October 21, 2008 Report Share Posted October 21, 2008 Normal, kust kick the choke off and keep it running on the throttle! Quote Link to comment Share on other sites More sharing options...
nzralphy Posted October 21, 2008 Report Share Posted October 21, 2008 Why would it be normal ?.....I'd say you have a fault. At best i'd say you have a leak of air in the rubber boot between the carb and engine. Check it by spraying brake cleaner on the rubber and the joints when the bike is warmed up. Try moving the carb about a bit when do it to get any possible hole to open up. If you have a leak the revs will go up momentarily. The only other fault i can think of is that you could have a starting jet or air jet fault/missing. Ralphy Quote Link to comment Share on other sites More sharing options...
