hi all after recently fitting my doppler s3r about a week ago and not upjetting i found it fine. But once in a blue moon like once a week on setting out for work in the mornin it would cut out or bog after riding it for about 5 mins so i deceided yesterday to upjet. On taking the carb apart i found out my main jet was a 53 and bby just lloking at some of the posts on here i realied this is quite small as i was lead to belive the stander main jet on an nrg is suppost to be a 63. anyway on upjetting i put a 58 in and put it all back to gether but when i tryed to start it petrol leaked out fo the overflow then i rememebered the white plastic that holds the float in had not been put in right i forgot the metal rod the holds it up :msn1: anyway on fixing that i wasnt realy sure what iv done so i put teh 53 back in and it was shitee to be honest that shitee that i called the aa once i had got to work on it. they said ring back when your leaving work so i rang back and they came out to me and looked over it they couldnt find anythink, So he decided to follow me home to make sure i was safe. Once it was home out came the tools and i thius time upjetted to a 60 and its absolutly fine, before i was scared to just leave it to idel and the lights but now i let it idel and it piacks back up again. Sorry for the lonng almost essay like post but just to tell you. frazer
