Posted September 16, 201014 yr Hi guys , I have been here a while now , and have had loads of help too ! I have a 2004 TZR 50 and have had her on the road about a month now ( after a whole load of problems ) ! To start with she would bog down and splutter at around 6500 rpm , but after around 1-2 seconds it would carry on to rev up . This problem slowly got worse over time , until now she intermittently cuts out while riding (with the choke off) . If I put the choke on she'll regain power again and rev freely again and run fine , however after around 5-10 seconds she will die completely and refuse to run at all ....unless I take the choke off, after a further 5-10 seconds im back to the same spluttering problem :\ ?!?! How bizarre so she will run with the choke and with out the choke , but also die with the choke and without the choke ? Any help would be vastly appreciated Thanks Again Jordan
September 16, 201014 yr Moderator does you carb float bowl have a drain screw? Try draining it... it might have some water in it.
September 17, 201014 yr Author Okay just checked the float bowl , the drain screw was really tight, so I drained it and flushed it through with a bit of fuel. Its helped partially, she runs fine with the choke on ( still splutters with the choke off ) and there is a massive drop in performance ! Before posting on here I gave the air filter a good clean , so do you think it could be the air fuel mixture ? Worth up jetting ? Thanks again oldgitonabike This isn't the first time you've pointed me in the right direction Jordan
September 17, 201014 yr Moderator Was it good before the air filter clean? What type of air filter is it? How did you clean it? Did you oil it before re-fitting? You say it splutters with the choke off...is this with a cold engine of a warm engine?..
September 17, 201014 yr Author It was spluttering before cleaning the filter , that's why I cleaned it , i cleaned it by flushing hot water through it , before drying it, hoovering it and cleaning it with Carb cleaner Its a 21mm K&N style cone air filter if that helps, I cant say I did oil it before refitting it, but i never have really , just tightened it up really tight ! She still splutters when warm , not as much , but still very noticeable ! Hope this helps Jordan
September 17, 201014 yr Does this spluttering only happen when the bike is in high revs ? Can you start the bike from cold with choke and then when its a bit warm put the choke off, will the bike idle now for a while ?
