I bought a 97 fzr 600 with 1100 miles but it wont start. I have Spark Fuel and good compression. I replaced the Stator, Carbs are clean. Engine head is clean. It sounds like its going to start but just an occasional backfire and popping noise.

My FZR 1000 cannot start. I have changed the spark plugs, checked the ignition coils and they are OK. I can see spark when I crank the engine. The carburattors were dirty, but I cleaned them. The fuel...


spray a little carb spray in the intake, open the trottle the whole way spray the carb spray and shut the slides try to start it. what happens did it try to start?? if so your dealing with carb stuff. i know you said that you cleaned the carbs but there a lot of little holes as im sure you know. pull your air/fuel screws and spray with carb cleaner and compressed air.
if it didn't try your valves could be out of spec. to tight and your losing compression. try the carb cleaner and let me know

2003 yz125 wont start


Not much info to go by, but i'll give some things to check. Got fuel? Got Spark? Got Compression? If you have all these things, after kicking several times, pull plug to see if the plug is wet. If wet dry with compressed air, ground plug on head bolt or use spark tester, Kick engine over while watching plug, it should spark. If not replace and try again. If still no spark, check kill switch with ohm meter to make sure is working properly. If still no spark you will have an electrical issue with either the CDI Box or Stator. If the plug was dry without fuel, pull fuel line from carb. check to make sure fuel is running, if not check fuel shut off valve. sometimes the shutoff valve will clog up. If all is well it has to be a clogged carb.. Good Luck

Fzr 600 got killer spark pulls fuel valves in check wont start just turns over once in a while it while spit through the carbs or backfire through pipe few and far between carbs are clean plugs are new...


This is not the news you probably want to hear but backfiring thru the carbs when you have good spark can be one of 2 things... either the valves are sticking / not closing properly due to carbon or the cam timing has shifted from the original position.

It would be best to do a compression test. You should have a minimum of 100 PSIG for an engine with major problems and up to 150 for a healthy engine. If you can not get 100 PSIG then it will be time for some serious engine service.

There is a possibility of the kill switch wire in the handle bar grip grounding under the grip to the handlebar but, since you said you have killer spark I doubt this is your problem.

Thanks for using FixYa.

My fz 400 wont start. it has fuel, spark and good compression.


if it has fuel, and "Good spark" and good compression then it has to be the carbs. Can it be push started? if you can push-start it, then i would suggest first purchase a can of Sea Foam @ Autozone $10 pour in 1/3 can to 2 gallons fuel, change or clean fuel filter and fill up the filter with "a little" bit of Seafoam push start it, then if it fires up, drive it around the block until your sure it will run somewhat,it probably will run rough at first until it works its way into your fuel system, then get on it once in awhile on an open highway for about 10 to 15 miles. if theres anything clogging up any ports or jets this stuff works pretty good... it worked for me after driving about 11 miles. it was still hesitating the whole ride but all of the sudden it spit something out and then all my hp came back...make sure your spark is a really nice big bluish spark...if it is redish purple then i"d check the pulse generators, they're probably bad.

Fzr 750 won't start


Best guess it that the OHC (Over Head Cam) chain is not timed properly. If too far out of time the pistons can bend the valves and crack the valve guides. Let's hope not. Put a timing light on it while the starter is turning the motor over. If the lines don't match up you had best take a look at the OHC timing.

Google " yamaha FRZ 750 RT " Right now there is a factory service manual for your bike for sale on ebay. A link to the Ebay site is there when you Google.

1995 fzr 600 spits and sputters


Personally, I would go back to the stock jets, stock air cleaner and stock exhaust then get the carbs balanced and synchronized. Aftermarket stuff is usually flashy and sounds like a good thing.. Sometimes it is but sometimes it ain't. Sometimes one add-on interferes with another. Put some faith in the guys who designed the engine in the first place. Go back to stock equipment and settings and see if the problem disappears.

Keep the cool aftermarket product stickers on the bike. No one will ever know.

Please rate my solution a " FixYa " if all goes well. Thanks!
