fzr wont start?
Got the VR in the mail earlier this week, went out and bought a RC plane fuel tank to do the overflow tank thing [which looks great!], the R6 short can should be in today with the rest of my mail, got a new maint. free battery all charged and ready to go. Itll crank, but the damn thing wont start! its got gas in the tank, air filter's clean, and good spark across all 4 cyl. but no dice. had a bit of an issue looking for the choke since i was used to the choke on my kawi 250 being on the left handle bar and to my surprise this one didnt seem to have it there, but by where the petcock would be on a regular bike? [unless im blind and it was there all along]
http://i3.photobucket.com/albums/y85.../IMG00230a.jpg I'll be giving it a thorough carb cleaning next week since ill have time then and see how it goes. But before i start taking things off it, anyone have any input as to what else it could be? :confused: |
My suggestion was going to be cleaning the carbs. Any idea on how long its been since they were cleaned or how long its been since the bike was ridden regularly?

It probably is just gummed up carbs. With him just leaving fuel in it they probably need to be cleaned out real well and I would thing youll be all set.

FZR carbs are finicky - I can pull mine and clean then in the dark at this point. I've had them apart more than 3 dozen times in trying to get my bike to run correctly. Tear them down, clean them out - all cracks and ports. Then put them back together and try again.

in the groove of the diaphragm? An air leak there and the carbs won't run for crap. |

confirmed! lever is on the side but it appears to be an aftermarket choke? its definitely not the OEM assembly, perhaps one from a different bike. I'll take it apart next thursday cause i'll have time then. The bike has had a yzf tank conversion so i didnt even see a petcock in there. seems like i have some restoring to do! |
so i cleaned the carbs thoroughly, assembled everything back. turn the key fuel pump winds up and does its lil thing for a few seconds and then it stops. I press the start button and the bike sputters but wont start up. you can hear it wants to start but it just doesnt go. How much is the fuel pump supposed to pump out when the key is turned to the on position? is it supposed to be a stream, or is it supposed to just drip a bit?

check your fuel filter, also alot of times on a cold start with carbs it can help to stuff a rag in the tailpipe (of course pull it as soon as she fires!). the problem is fuel atomisation and sometimes that extra restriction is just what you needed. good luck!

Don't do starter fluid...
Get some seafoam if you're trying to short cut. However, you should replace the gas. Gas can go to shit in as short as 3 weeks in the correct environment. A quick way to check is to get a spray bottle of known GOOD GAS and spray it directly into the carb like you would starting fluid when you're cranking it over. If it starts... it is either your gas or your gas delivery. Have you checked for spark? Also, moving this to tech... sorry I missed it before. I'll try to help the best I can over the internet... take it for what you want... Ithink I know how to turn a few bolts... |
seafoam FTMFW

cleaned out the plugs really good, fired her up and she ran with the choke on. wouldnt run for its life without the choke. So im gonna swap fuel filters again, maybe this one wasnt as clean as i thought it was after all. i'll update in a few minutes
UPDATE: fuel filter changed, still wont stay on much longer without the choke. and it keeps backfiring. timing issue maybe? I adjusted the idling screw and it helped some now it idles at about half choke. any ideas about what else it might be? |
Have you pulled the air box and checked to see if all the carbs are spraying gas?
May be looking into pulling the carbs. You will need a service manual. Or take them to a dealer for cleaning and sync. And would be an ideal time to consider at least a stage 1 jet kit. |

Most of the time your manufactures say you are suppose to sync yearly.

damn i havent been around in over a month? crazy!! here's a summary of what's been happening. I bought new [used] carbs for the bike from craigslist for 50 bucks. threw them on and after some slight tuning she runs, idles rought but she runs. without the choke! Ive yet to take apart the old carbs to see exactly what it was that was causing the bike to run like trash. I'll do that some time during the week. Next stop is this r6 shortcan mod! thanks for all your help guys.
