Hi Everyone. Long time reader on this forum, but first time poster. I have myself a problem and need some expertise in getting her back to the road.
“Black Betty” my 08 black ninja 250r has some serious problems with its fuel/fuel system. When I start it up, it will idle fine, but when I give it some gas, at around 3,000 or 4,000 rpms, it acts like it is not getting any fuel and will putter out and die. Maybe a throttle line problem? It is very similar to having water or excess sediment in your cars gas. I can ride it in 1st and 2nd gear if I choke it up to around 7,000 rpms and hold it there, but there is nothing else left. I added some Heat to the gas to try to burn off any excess water that might have gotten in to the gas, and it didn’t seem to help.
I did not winterize my bike ‘cause I rode it once a week or so during the winter here in Georgia. I get my gas at racetrac and have always got the premium in hope that it would be cleaner. My bad there.
I am going to replace the fuel, and thinking about pulling off the gas take and replacing the fuel pump while it is empty. The problem is that I am not too mechanically inclined. I have the service manual that someone posted on this site.
So my questions for ya’ll are:
1) Do you all think I am right in my diagnosis of fuel problems? Or has anyone else had this problem?
2) Should I change the fuel pump and if so, what is the serial number/ part number of the fuel pump?
3) Do I need to take out and clean the carburetors, and is that hard to do?
4) If I do this is there anything else I will need to make sure I can get it back together and working again?
5) Is it worth it to try to fix it myself of should I just take it to the shop
