Fuel Filter, yes or no?

Another basic thing to do is to install a fuel filter on the main fuel line / hose into the carburetor.

They are not fitted as standard and they remove all the little nasties from the fuel which will find it's way into your carburetor & engine and build up and accumulate over time.

I fitted an inline fuel filter to the fuel hose but have since noticed a problem with the running of the engine. Fuel is getting to the carb for it to be able start, however it's cutting out indicating that it is disrupting the regular flow of the fuel since being fitted. It looks as though another hose will have to be bought and fitted without a filter once again to resume normal function. And the fitting of an fuel filter isn't perhaps a good idea with this bike.

If you do wish to try fitting an inline fuel filter you can follow the following:

Wait until the tank is pretty much empty other wise you will have to drain it out before hand.

The fuel line itself is the hose indicated in the below picture. The other hoses, one is a breather and the other a vacuum hose.

With a flash of inspiration I used a g-clamp to clamp the hose shut near the tank and make sure that no fuel could flow out. The hose obviously then needs to be cut in half.

Check the flow direction / correct orientation of the filter, which should be labelled with an arrow.

You will need to make sure that the hose is securely attached to the filter ends. The wire clips availabe don't seem to be that tight, so I would recommend using a micro tie wrap / zip tie pulled tight with pliers. You could even double up if you wish to.

However, as mentioned before, It didn't seem to be such a good idea with this bike. Fuel flow disruption seems to be too much of a problem.
There are some round looking ones (filters), also plastic available from the online spares site for the bike but they are pretty much the same thing, just a different shape.

The problems experienced are definitely a direct result of adding the filter to the hose. It's likely that the pump is strong enough on this bike to supply fuel to the carb at a steady rate as it was but not through the filter when also added to the mix. Maybe the filter used here added more resistance than others available? I'm not sure but, the answer for me here is to revert back to a straight through hose to get things running as they were again. I don't think I will try with another filter.
