HELP ! after service bike now runs like a bag of spanners !!

[polecat]

Me and Engines dont get on

Ok so I thought I can do a service of my bike,how hard can it be

Brake pads all new and bled no problem,took out the restrictors no problem changed the Air filter no problem changed the plugs (few problems with gravel in the recesses which I got out ) and flushed out the old coolant (just fresh water in waiting on engine to flush that again )

Ok so now I need to warm up the engine to change the oil so put it all back together and start the bike... starts on choke runs like a bag of spanners with lots of smoke

Now it worked perfectly before restriction and perfectly well after but now it doesn't so I took the plugs out again and put the old ones in, same thing happens clouds of smoke and running rough needing lots of throttle to keep it running.

Plugs were quiet wet when I took them out so I put the new ones back in.

Only thing I can think of at the moment is Have I got the HT leads on wrong ? It says in the manual left to right 1,2,3,4 which is what They are

Any ideas before I make things worse ?

You obviously took the carbs off to remove the restictors, have you got them seated back on correctly? Are the cables free, especially the choke?

Is it miss-firing, if so could be you've got plug leads mixed, but I think it would be a real bugger to start if you had.

When they fitted the restrictor kit, did the change the jets too or was it just the washers?

Gonna go check all those things cheers

I fitted the restrictor and no jets it ran great before i restricted it and great after so I dont think its that ?

Also wondering if It may be caused by too much oil on the air filter ? may try removing it quickly to see also

[eastanglianbiker]

if you have oiled up the filter then you could have to much oil in it take the filter out and see if it runs any better

[techno]

Ideas yep take it to a proffessional

Its stories like these that make me glad I don't ever touch my bike!

[Guest Hodgy]

Is it a K&N type air filter not a paper element type?

If it's K&N then it only wants a very very light oiling and shaking off well before fitting, if it's a paper one it needs to be dry with no oil on it

Ah Haynes said oil it !

Im gonna go take it out and see what happens ..............

If you got the HT leads in the wrong order it wouldn't start.... I know this from experience..

As the other guys have suggested....try running the bike without the airfilter element......if it runs better you know that you over oiled it....

[Stu]

You might find that it makes no odds which way the HT leads are, as long gone are the days of dizzy caps and rotor arms and all plugs will spark at the same time

But don't quote me on that as sometimes one coil will do two plugs and one for the other two and could spark at different times!

I would check the carb connections as said and the air filter

[Tango]

I think a lot of bikes these days have the coils built into the plug cap which are controlled by the ECU......but on a lot of IL4's and IL2's the ignition will spark on the compression and exhaust strokes anyway.

Firing order is usually 1243 ?

[polecat]

jeeze

I took out the new air filter and fired it up and it runs perfect !

well I double checked the Haynes and it said to coat it in oil until no drip come off it then fit !

So oil on the filter as Hodgy said caused the bike to run like it was on 2 cylinders

Fortunatly it is nothing more serious but it sure scares the hell out of you when your bike stops running right !

Thanks to all those who replied as it really helps to have a little moral support

I tried 1243 and it was just as bad but made little difference but the haynes said 1234 but my confidence in Haynes is a little wary now

To Techno, I would love to be able to afford to put it in for a proper service but this way I can at least try to keep the bike in as good order as possible despite making mistakes along the way

[mattycoops43]

Haynes is pretty good to be fair, more likely your idea of 'oiled' and theirs are different! Glad it was something easy tho.

[polecat]

can I salvage the new filter or will I have to get a new one do you think ?

[Guest Hodgy]

I don't understand why they would say oil a paper filter?

Buy a new one, put it in dry and keep the oil for the engine, problem solved

I have still the engine oil to change

Yeah ill put the old back in (rescued from bin) and start again

In Haynes defence the fzs is mixed up throughout the manual with the YZF as its a shared manual and the coat in oil statement I re read is refering to the YZF ) it does not actually mention the Fazer filter !

Lesson learned for next time

[mattycoops43]

I got that bike and manual! It actually says you can blow the filter out with compressed air as long as its not too far gone! It is a bit of a headache deciphering which bits are for what bike.

At least there's no harm done except a few quid for a filter, the YZF must have a K&N type of filter.

Glad it's sorted

Yep, you never oil paper filters, it blocks them up and you were basically trying to run it with massive choke on . The smoke was just the oil you put on it burning off. You only oil foam filters

[polecat]

I thought it odd at the time

Anyway it really made me realise the importance of air filters cos when they are clogged the bike wont run

[pointblank0]

I thought they were all paper filters nowadays?

No....quite a lot are still foam filters....and especially if they've been replaced with K&N or Pipercross filters.....
