Is there a disposable paper filter option for the 630? So far, I'm not a big fan of the whole "clean and oil" thing with the foam filter. I probably overdid it on the oil, but I cleaned and oiled mine, and after some riding, I started to get this oil ooze out of the airbox. I don't know, maybe I'm just doing it wrong.
I'm in the same boat as you. This is my first off-road two wheeler. I have had a lot of on-road bikes. My quads have all had K&N's which I'm really good at servicing. But this foam and oil filter cleaning can best be summed up with one word......"Yuck!!"
I do know that No-Toil makes a disposable pre-oiled foam filter. I'm just not sure if they have one for the 630.
paper filters dont do real good for dusty conditions found off road. Frequent foam air filter maintenance is just part of the gig.
Once a paper element gets wet, it tends to get soggy and not pass air anymore. But it will pass water pretty easily. I had a friend who bought a new Aprillia 550 and went through a water crossing pretty fast while wheelying. It had a paper element on it and he had to stop (well, the bike stopped), remove the element and also drain his carb.
Yep, too much oil. You have to "wring" the filter gently, but firm enough to squeeze the oil out. I let mine sit on a couple of paper towels for 30 minutes or so after I wring it to let any oil residue drip out. Buy a second filter & keep it at the ready oiled & sealed in a zip lock bag, I stand mine up & let the excess oil drip to the bottom of the bag. I have done this for 5 years now with no problems....Mine is a SM610 that doesn't see the dirt very much at all. FWIW
They don't make a fast filter kit for Husky's... I actually emailed them inquiring about new stuff i.e. air box covers etc...; we'll see what they say...
Buy a couple of foam filters and always have a clean one ready to go. The best filter oil is the one that comes in an airosol can; just spay it on inside and out and then massage the oil into the foam filter by and hand. Fit the filter using a little EP2 grease around the edges to get a good seal. I wash my filters in a little bit of petrol before washing in a degreaser mixed with water. Once you get the hang of it it is no sweat. At least with a clean and well oiled foam filter you know your engine is protected.
Washing in petrol is no good for the adhesives that hold filters together. Same deal with degreasers that mix with water (eg CT-14). Stick with kerosene followed by warm water and dish detergent or follow the manufacturers instructions.
I use this: The cleaner is powder; you mix it in a bucket of water and wash away. I put the oil in a spray bottle, hoping to be able to mist it onto the filter. The oil is too thick for that, though. It'll only come out in a stream. So, I just squirt it all over and try to squeeze out the excess.
I did the same thing about a week ago on my TE 510, clearly way too much oil (which now that I know won't be a problem - just gotta wring it out gently and thoroughly). This lead to another problem in that the bike has started running poorly, especially in low revs - I thought maybe it was just starved for air as there was too much oil on the element but I have recleaned and re-oiled the element and cleaned any oil from the airbox and it was still running poorly (would idle ok but would bog down if you snap the throttle on). So then I thought maybe it had sucked droplets of the oil into the cylinder and maybe gummed up the spark plug but I changed the plug and the problem persists. Could the oil droplets have got into the carby and blocked up the pilot jet or something like that? the bike still revs out when you open up the throttle gently but bogs down in low revs if you snap it on. Cheers .
Seems unlikely. It'll run rich for a while if over oiled, but will eventually sort itself out. Seeing as you have redone the filter and replaced the plug my No.1 suspects would be gunge in the carb or maybe if the carb has an inlet screen a (partial) blockage there. The latter affects the float level which if not correct can cause all sorts of problems. If you had the tank off at the same time then removing and replacing the fuel line is a good way to introduce junk into the fuel system.
Hmmm, didn't take the tank off just loosened the bolt that holds the tank in place (where the seat slides under) and lifted it a touch - just enough to get access to the plug. Haven't had a chance to clean the carb yet, don't know if it has an inlet screen (it is a keihin FCR MX 41mm I think) but convinced now this is where the problem lies, I'm a bit scared of carbys lol. Will have a crack sometime this week and worst case is I will have to take it to the shop I guess.
Okay, that might eliminate those potential sources. Another cause is that the engine is idling a bit too low. No air leaks? Check all of the small stuff before ripping into the carb. Carbs are not scary once you have got your hands dirty once or twice. It's not like you're setting up a new carb. That job is done so it just needs to be clean inside and to do that it does not need a complete strip. This may be stating the obvious, but I mean it kindly. It is odds on that when a bike is not running right after a service when it was running right before it is something that the wrench has done. You'll need to back track through everything that you touched. Tip: If you have a helmet cam, strap the thing to your head when working on the bike. It will document everything you touch and it could save you a heap of time trying to work out where stuff goes or what went wrong.
Checked for leaks, couldn't find any. Didn't get around to the carb I've been busy but then needed to ride it to work yesterday as I lent my car to someone and it actually just kinda came good. I'm thinking it might've been running a bit rich and there wasn't actually much wrong with it in the first place haha. There was however a bit of build up of oil at the bottom of the filter element again (after sitting for about a week) and a few drops in the bottom of the airbox. When I reoiled the filter element the second time I wrung it out for about 15 minutes and couldnt seem to get any more oil out but it still seeped out slowly (very slowly - it wasn't like that the day after)??
There ya go. It might be easier for you to work out how much oil you need in the filter, add only that required + bag tax and knead it through in a zip-loc bag instead of trying to wring out excess. It'd be worth getting yourself an extra filter to leave in the bag. These things can never be changed often enough.
