Saw this in a recent thread and HAD to have it. Hell all pump nozzles should have a filter on them in my opinion! So I ordered one and got it in about 3 days all the way from kangaroo land. Impressions; Very simple product, think female condom with microscopic holes in it. Shove it up in the hole and leave it there. Day to day livery; Works good, can cause a bit more splash if you dont go balls deep with the nozzle. Which we cant because then the nozzle will turn off when it gets most of the way full. Stupid california nozzles. This thing is a great idea and added protection, the VAR0001 fits the 449/511 bikes. I may add a bit of gasket maker or shellac or grease or something to hold it in a bit more semi-permanent as it did come loose on one or two fillups. Great product great simple idea and I think we all should have one. (I am not affiliated and paid full retail price on it)
We used these on the new Huskys, they were messy and didn't help the efi from clogging. The injectors on the 449 are much larger and can can take quite a bit of debris. They have bag filters attached to the pump that are very good. We have a new fuel filter coming that will attach between the fill tank and the front tank. These will be cleanable fuel filters that will filter down to 10 microns.
Sounds awesome tinken. This is a must for when you get gas out of a can or pump....stop the stuff from even getting to the filter on the pump. Do you want to replace the pump filter? I sure as hell dont. So this will help. Also keep debri from around the cap getting in. Its not going to help a ton but any little bit will be good. Even If I had 3 fuel filters in the system I would still use one of these.
I agree huskylove, will keep mud and dirt from getting to far and these bikes are kinda hard to fill cleanly after a good mud ride. I just pulled my fuel pump to check the filter on the pump, looks spotless which is nice after almost 6000 miles.
In fact tinken you should be a dealer for them Buy a box for some different bikes and put them on the site if they will let ya.
Instead of a sealant maybe make a gasket out of fuelproof rubber or similar as it might be a tad tricky to remove when you clean it. Its also interesting to pull it regularly and see how much carp would have otherwise been entering your tank.
I just purchased the Pro Fill fuel filter for my 690 fuel pump, it looks much more robust than the stock filter, the stock one is pretty ordinary and dirt might even be able to bypass it. I think a sock on the fill point is a good preventative measure, the filler point is similar to the 449/511 so stuff can fall in even if you're careful. Stopping dirt from entering in the first place is better than pulling the fuel pump and replacing that one, or worse- suffering a clogged injector or worn fuel pump. I think FI is great but in the scheme of dirt bikes it is ~new. Soon the cumulative hours on the FI bikes will be high enough that we might see more dirt related problems.
On the 310 they fit just right... Snug and do not rotate or move as the cap cooperates nicely. Used mine for a month or so now with multiple fillups. I carried a jerry can to Oregon and with any metal can some paint will chip and with gale force winds there is apt to be debris if not careful. For me on the 310 it reduced splashes since hits the sock before the bottom of the front of the tank so doesn't splash back. In any case keep the debris from getting far into the system. I'de prefer a large sock as this to collect debris as opposed to a smaller filter that may be fine but also may clog if the area isn't adequate for maximum flow. I would want it to be immediately accessible to clean or replace. So far so good with no downside for the average rider seeking simply to keep debris of any size from getting into the tank. Multiple easily accessible filters would be best so good first line of defense.
