Last Saturday I decided to take shortcut across grass, whilst it was raining and learnt the hard way that a huge pot hole can send the bike slipping out. The bike fell over but because the dirt was soft, there appeared to be no damage to the bike. It stalled after it was down for a while, but I was able to start it back up and get home (500m). Afterwards it wouldn't start, it was just turning over doing nothing. I was able to pushstart it and gave it a bit of a squirt and it appeared to be fine. I was able to start and stop the bike without any problems for a few days. Now it's just turning over again, without starting. I'm sure it has something to do with the drop as it always starts perfectly before. Has anyone got any tips? Cheers btw It's an FZR250 3LN3
I'd start with th most likely culprit. First check to see if you have spark when it wont fire. pull one of the plug wires off of a plug, insert a philips head into the wire end. Now hold the metal shaft about 2mm away from anything metalic (DONT TOUCH THE METAL ON THE SCREWDRIVER!) You should see spark when you try and start the bike arcing off of the shaft. If you do, then it is carburation, (which I doubt because all four wouldnt have fouled at the same time) or fuel pump. If you didn't see spark (more likely) its a problem in your electrical system. This can be very time consuming to diagnose. Time to break out the volt/ohm meter <!-- s:-? --><img src="{SMILIES_PATH}/icon_Eyecrazy.gif" alt=":-?" title="Eye Crazy" /><!-- s:-? -->
pull your tank off and make sure your air box hasnt decided to detach itself from the carbs some times the rubbers become hard and are easily knocked off.
If it is not starting but cranks over check the battery voltage when cranking. The FZR is notorious for not firing if the battery is a bit weak. If you have an old battery it may be that when the bike fell over that all the sediment that accumulates in the bottom of the cells as swirled up and done some damage, perhaps causing the battery to lose efficiency.. TRY another battery first. Back in the olden days (when I was young and dinosaurs roamed and petrol was 49c a gallon) a quick fix for a stuffed battery was to tip all the acid out and flush the battery with distilled water, and either put new acid or carefully use the old acid and try not get the sediment back in the battery. I think the newer bike batteries dont have filler plugs as such, so it may not be possible to do this.. WARNING - BATTERIES CONTAIN SULFURIC ACID - IT WILL BURN IF YOU GET ANY ON YOUR SKIN OR EYES
my bad i missed the (for a few days part) <!-- s --><img src="{SMILIES_PATH}/icon_redface.gif" alt="" title="Embarassed" /><!-- s -->
chances are he dislodged all the **** that was sitting at the bottom of the carbs, time for a good clean out when dinosaurs ruled my earth petrol was only 19c a litre <!-- s:roll: --><img src="{SMILIES_PATH}/icon_roll.gif" alt=":roll:" title="Rolling LoL" /><!-- s:roll: -->
sounds like one or the other - hopefully we will get some feedback when it sorted Thats is about the same as my gallons/dinosaur price but must have been after mine as you had changed to metric... <!-- s --><img src="{SMILIES_PATH}/icon_smile.gif" alt="" title="Smile" /><!-- s --> I thought I was the oldest person on this forum...
Add 10 - I am a late starter. I did have a short period where I had a learners licence at 18 but never bought a bike, I just rode other people's. My two boys got into dirt bikes and then got their learners licences and so did I. My eldest son just bought a 2005 SUZUKI SV1000 which is an excellent bike. I think I like the looks of it more than mine but it is a bit thirsty.
