Echoeone Posted April 21, 2009 Posted April 21, 2009 Hi - need a bit of help please guys. Trying to get a ZZR1100 D5 back on the road. The bike runs but will not tick over properly. When we tried to balance the carbs - no4 did not show a vacum. Then after much routing about it mysteriously appeared on the vacum guage and we could balance them. The prob is with the bike & seems to be intermittent. Also as soon as you take the choke off the engine stalls straight away. The only exception is when it is fully warmed up - then it ticks over ok. It also seems to run hot and makes a sucking type noise. Suspect the carbs but where in the carbs should I look? Have had them off and can see nothing obvious, but not an expert so any help/pointers to where to investigate very wlecome.thx Quote
Guest Posted April 21, 2009 Posted April 21, 2009 check the rubber chimneys that attach the carbs to the engine, you could have a leak.. therefore sucking in fresh air, rather than carb fuel mix. Quote
Echoeone Posted April 22, 2009 Author Posted April 22, 2009 Thanks - I have taken the carbs off and had a look at the rubbers on the engine side as you suggested. They all look intact. I can't see any cracks or splits and the allen bolts are tight. Any help welcome as proving difficult to get to the bottom of. One other point is that when I have the engine running and rev it - the engine goes up the rev band but then takes along time to drop back down again. It stays at say 3k revs before dropping back after about 5 seconds. This is the same whether the choke is on or not. Carbs look clean inside but something is a drift? Quote

Carbs look clean inside but something is a drift? ok, how about the connections with the airbox? remove the airbox coverand filter, and see if the problem is still there, if not, then its related to the filter/cover.it sounds most likely a vacuum leak or could need balancing.. see "Guides,Manuals, & General Info"PM TimR, he's a ZZR600 man, and may have further insight..
