help fireblade westy wont work
hello all
i have recently got a westfield megablade and have got some running problems with it.
When i first got it it run was quick but wasnt running at its best,on my third trip out in it i had gone about 3miles and it started to slow and drive
like it was running 2/3 cyl and then stopped all together,when it cooled down it started but didnt run well,after changing coils,plugs,leads,and
having the carbs cleaned tuned and balanced it runs fine in the drive way,went out to test it got about 1 mile and had very little power and then did
same thing and stopped and this time didnt want to start again and still wont start even when cold,does anyone have any ideas what it mite be any help
would be great thanks

Have you checked the fuel is coming through? if using the standard blade pump the points get corroded and the pump doesnt work properly. Check fuel
first and let us know, then we can suggest other routes

has it ever run correctly?
Fuel pump/filter?
Test by removing pipe at the carbs, should fill a milkbottle quickly.
What air filter are you running?
is it jetted to suit?
Do you have a choke set up on it to start from cold?

Sounds like fuel issue to me aswell, might be worth putting your location on your profile, someone local to you might pop round to hve a look at with
you.

So you are using a fuel pump and a seperate pressuer regulator?
Whilst some have this set up and get it working, most find that a suitable bike pump with it's own built in regulation is most effective
/reliable .
PS the dribbling does not sound good and suspect that is not enought for real driving

Although my money is on fuel too, I had a similar problem in a tin top. Turned out to be the coils breaking down.
Also had a Maico that would tick over and rev the the moon at standstill, but would splutter when ridden.
Found the cut off switch wire earthing against the forks, the wind was blowing it back!

Are you using the standard bike pump, I.e. Round cyclinfer thing with a black end cap? If so these are self regulating. The dribble doesnt sound good!

As the above posts don't fanny about with an aftermarket fuel pump and regulators they generally cause nothing but grieff.
Get the standard pump which is self regulating and looks like this
You can use a pump from any carbed bike of around the same size, zzr1100 pumps tend to be cheap and readily available on ebay for less than £30

You don't need much pressure, a few psi is enough, does need to deliver ~1 liter/min to carbs though.
I would be checking the coil HT leads/connections even if they have been replaced, they have a habit of breaking down and creating bad connections.
Also check plugs to see if its been over fueling and fowled them up.

iv been reading about reg/rec getting hot on fireblades,mine does too so will move it and put a fan on, but would this be the problem as it seems to
run worse when it gets hot,some one i spoke to seems to think it wouldnt effect the running of the engine but have seen other post that say it
mite,any ideas cheers

If the rectifier pops then you stop charging the battery, if this happens when you are driving then you will develop a misfire as the battery goes
flat due to the battery not having enough juice to create a good spark.
I'd be pretty confident that you identified the problem when you found that fuel "dribbled" out of the regulator.
