How to remove injector filters?

[sproggy]

I've read several mentions of little filters in the injectors but a search hasn't thrown up anything about how to access them. And the parts fiche doesn't mention them so I assume they're part of the injector assembly and not available separately.

Are they removable to check for dirt and clean if necessary?

No mention of such a part in the 'parts fiche'.. if this part exists then it wuld appear to be integral and not accessable.... shouldn't get dirty as its downstream of the fuel filter, anyway.

I shove a can of wynns dry fuel in the tank every spring.. this cleans the injectors AND removes any water build up in the tank. job done.

Are you bored? got a problem with the injection??

That's a good theory, but there's potential for dirt to occur downstream of the filter - entering the QD connectors when the tank's off, bits of fuel pipe breaking away etc. I ask because there was an 850 for sale on here a while back which the owner couldn't get to run right, and the guy who bought it traced the problem to the injector filter(s) being partially blocked. Thought it was worth checking.

Done a can of STP injector cleaner and done a can of Wynns dry fuel too.

Bored with the bike running badly I bought a pair of used throttle bodies and a set of new throttle cables but it looks like they're not going to turn up for the weekend. So I plan to spend my tinkering time over the weekend looking for other possible causes of bad running just to eliminate more things. I need to check the resistance of the injectors too.

Recently decided to get the fuel injectors professionaly cleaned and tested at around 120k km by the guys at www.injectortune.co.uk.
Total cost was around £25. This included a resistance test, cleaning, before/after flow test, changing the filters & O-rings of the injectors and return shipping.
Turnaround time was about 3 or 4 days.

If you can get hold of some cheap isopropyl alcohol you can use that to get rid of water in the tank. I'm pretty sure that isopropyl alcohol is the main ingredient in most fuel additives anyway.
