My bike isnt starting :S

find a wrecked bike and swap the engine...

 

I'd check/do the adjustment of the valves first. Find out for sure if it is valves or rings.

For $385 I'd expect this to already be done and noted.

I'd expect maybe $2000 if the cases had to be split.

 

WOW sounds like this is a standard thing for ****** mechanics to do then.
When I first got my bike I flooded it heaps with my newby riding and basically got to a stage that it wouldn't start at all. I took it to a mech who ran a comp test. He told me the compression was very low. I said ****, he said he'd fiddle with some valve things and what not and he'd get back to me. He rings me back and says it's kaput and I'm gonna need a new engine $1500+.
**** THAT I said. The bike used to run I said there is no way it just fucks up all of a sudden fzr's have generally low compression anyway, The fact is many mech's just don't have experience working with these little bikes. My step dad is a car mechanic and told me it sounds like bullshit.
I got the bike home and tried to start it, I got nothing. So like I said earlier I just held the ignition switch on for like 5mins out of pure frustration trying to get it to start twisting the throttle slightly every now and then. Eventually she sparked up, I had to fool round with the idle nut so she wouldn't just die but eventually she got started. I couldn't believe it. Basically what I'm saying here is the guy is bullshiting you! The story your telling me sounds way too familiar to my situation.

Where are you in Oz? Maybe I can come round and see if the bike sounds the same as mine did when I had probs. What I learnt is, These bikes love to be ridden and ridden properly, if you leave em alone and try to get back to em after a while for a joyride you don't stand a chance they have to be used constantly.

 

Here here! FZR's are a riders bike, not a posers bike. If you want something bling just go buy a CBR. The amount that my FZR250 taught me was incredible! I thought carb's were some sort of black art until i was forced to learn. <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: -->

 

Wow that engine isn't even adolescant yet.

Seems that carboned up valves can end up a problem if you dont keep the bugger over 7krpm (you know, not including trawling along and stopping and all that..) Perhaps that is the issue. Carboned valves have caused low compression issues.

Oh, and you didn't mention what the compression readings were. It might give the issue some kind of scope to hear it.

 

If the bike has not had the shims done on it that you know of then that will need doing. T bone recomends and so du's the manual that it's due every 12000km

 

too bad i didnt hold onto my wrecked fzr or i could of sold it to u...
front end collision but engine was fine..n runs strong too..

if ur in melb...whats that guy that boz recommends for fzr parts etc.? bruce or something? mayb try get him to fix it or sell u an engine?

other than that....nuffin like that has happened to me for the 30,000km i had mine even if i didnt ride it for a month!

gl...hope all goes well..

We can do this

If you really want to be sure go to supercheap auto and get yourself a compression gauge. Make sure it will fit the smaller bike spark plug holes. The guy at the parts counter will advise you. All you have to do is remove the plugs and crank the engine a few times with the gauge jammed in each plug hole. Real simple stuff. If all of the cylinders read in the same ballpark but low, I would bet there is something amiss in the valve train rather than worn rings/cylinders. To check the ring condition a tablespoon of oil in each cylinder and a few cranks will significantly raise the compression. If not you have valve problems. Next check clearances 27K km is not going tot wear one of these out unless it has been run with no oil at some stage. Once you;ve done the valve clcearance and they are fine then check the valve timing and tensioner. You may have slipped a tooth at some point in time hence knocking the timing off.

 

Mr Starter has good info. Give it a shot, only takes about a half hour.

I do recommend getting the Compression Tester that screws into the spark-plug hole over the one that is just held in the hole. You'll be able to do a leakdown test with it as well.
