Hilko Posted August 1, 2018 Posted August 1, 2018 Hi everyone. New to the forum and am looking for advice. Just rebuilt a gsx1100et and having problems with fuelling. Float bowls in Carbs 1 and 4 were completely dry after turning the engine over for a while so checked fuel being sucked from tank and ok. Removed carbs and poured petrol in through intake tube all carbs filled ok. Put carbs back on bike and runs only on 2 and 4. Spark is ok on all 4 but seems to be no fuel getting to 1 and 4? Any ideas. Quote
gsx1100e Posted August 1, 2018 Posted August 1, 2018 Welcome to OSS, and pictures we like them.... Did you check needle valves? Quote
Hilko Posted August 1, 2018 Author Posted August 1, 2018 All jets incl needles etc have been renewed. The bike did run ok a few weeks ago but just came back after holiday and tried to start with result mentioned earlier. Quote
gs7_11 Posted August 1, 2018 Posted August 1, 2018 Sounds like your tap isn't opening fully. If all the carbs fill ok when you pour petrol down a pipe, must be the tap. Quote
Hilko Posted August 1, 2018 Author Posted August 1, 2018 Never thought of that. I assumed that as fuel was coming through it was ok. I’ll check it next time. Cheers. Quote
Hilko Posted November 7, 2018 Author Posted November 7, 2018 Been away for a while but just checked the fuel tap as suggested by gs7-11 and sure enough the rubber diaphragm was knackered. Replaced it and checked everything else again and running sweet as a nut! Thanks for the help, much appreciated. 3 Quote
