couple diff. maintenance questions...
« on: December 10, 2002, 11:43:26 PM »

1.  are the only brownish/tan air filters K&N??? cuz i was going to replace my filter and i took it out and its not white heh.   i checked on it for something that maybe said K&N but nope...

2.  is oil on the engine side of the air filter bad???  if so whats wrong...  only thing my bike has problems with is starting in cold or wet weather.

3. if the oil ISNT a problem... then what else might be giving me a hard time starting up in the cold... (i just recently replaced spark plugs and changed oil)

4. whats the best way to repair cracks, rash, and bad rash to where there is a hole on fairings?  i was just gonna use fiber glass and resin (sp) but i figured i should ask the pros first Wink  

5. ive noticed this before but forgot to ask... on the right side of the engine.. theres a little bracket i guess u might wanna call it.  its just a piece of metal screwed into the engine, then comes down and you can screw something in at the bottom... but on my bike its not being used.  

6. and last but not least... do any of you guys have any screws/bolts/allan key fairing screws that fit F2's that ya dont need? or know a place i can get them cheap?  

well, thanks in advance you guys.  later

1. The stock air filter is a redish colour. The stock one has a metal on the one side and nothing of the other. I put in a K&N and the quality I thought was rather shitty for the price of the things. The Honda seems to be a much better fit than the K&N but the K&N has better air flow.

2. An oil film is nothing to worry about as the motor I believe breathes back into the air box. Since every motor has some blow by (gas mixture escaping past the piston rings into the crankcase) there will always be some pressure in the crank case. Since a pressurized crankcase is not good because you will blow gaskets like crazy they have a vent going back into the intake. The idea here is to equal the pressure on the crankcase. This is were the oil film would come from. If you have lots of oil I would do a compression check to verify all the cylinders pressures. They should be within 10% of each other. Too much blow by will start pushing oil up into the breather hoses which will in turn deposit oil in the breather box.

3. Possibly low compression. How many miles on the motor? What was the last readings on a compression check?

4. I would recommend having any crack or hole plastic welded since it is so strong afterwards. They claim the welded area will be just as strong or stronger than the original section was. Be warned though it does make a mess when it done so have a good body shop in the area scoped out prior to taking it in. Also make sure the body shop is good at mixing colours. There is only one place I know of that has paint the supposedly matches bike, Color-Rite.

5. The only thing that I can think of is possibly where the lower bolt for the fairing goes. Could you take a picture and send it to me or post it so that I know exactly which part your refering to.

6. Talk to Jeff. I believe he has a bunch of nuts and bolts. Not sure if they are the same as an F2 but worth a try.

1. agree with coke on the quality of a k&n on the f2/f3 (heard they work well on f4?)

2-4 can't help you more than coke did

5. are you referring to the brackets for the center (or centre) stand - the one we didn't get in the states?

6. check lowes.  they have a bunch of specialty fasteners for pretty cheap.  i know i bought some of those clips for the bolts (slide on fairing & have threaded side) from my honda dealer at $6 usd each - lowes had the same thing for about a buck.

its not alot of oil.  just a film.   K&N dont have that metal screen? cuz this filter does... so that means its stock?

never checked compression, dont know how? does a shop have to do that?  and i dont know the miles on the engine...   its a reconstructed bike. the odometer reads almost 34k... but who really knows?

as for that lil bracket... i couldnt take a pic cuz i dont have any way to get it on a computer.. i could sorta draw it on a pic of an engine or something for you and email it??   if you want.  i dont think its for a center stand. its on the front right side.  

oh, and seeing as this is reconstructed...  i would like to dive deeper into the bike to see how everything is, but also worried cuz i dont have much experience with mechanics.    you guys think i should just have the bike taken to a shop?   im probably gonna go to school for automotive shit so i wanna learn this stuff.. but i would also like my bike to work come spring time Smiley haha  

thanks guys,  always alot of help

They both have a metal screen but the one on the factory sits flat on top of the filter pleats whereas the K&N one the screen follows the pleats.

Checking compression is really easy. The only hard part is getting the right adapter for a motorbike since the plugs are so small. I'll post the section from the service manual later tonight since I don't have time this morning.

Is this bracket hidden behind the fairing? I'll post a couple of pictures for you to download and then you circle the part your talking about.

6. and last but not least... do any of you guys have any screws/bolts/allan key fairing screws that fit F2's that ya dont need? or know a place i can get them cheap?  



Ok, I'll add what I can:
#1, K&N would most likely have a reddish tint due to the oil thats used for it. But, it would say K&N somewhere on it. I have a K&N laying on my basement floor, I can send you a pic if that helps.
#2, no it's not bad, as long as it isn't much. It's just oily air that was vented to the air box from the crank case, the oil settled on the inside of the air box.
#3 is a tough one. Did it start OK before you screwed with it? If so, then you did something to make it not start. If it's always been that way, then you have to look elsewhere. I disagree with the compression check. If it had low compression, it would always be hard to start. Plus, it'd be many miles before that was a concern. I'd check a few things. First, it could be running lean. Colder weather would make it leaner and that may be enough to keep it from running. Also, has it sat for any length of time? If so, then perhaps some gas varnished and clogged a passage in the carb. What else has been done to the bike? Full system? Was it properly jetted? Also, were you trying to start it while you had the sir filter off? The extra flow would make it lean as well.
#4 There is this stuff called Plastix, it works well. And this other stuff called Fuser. The first stuff can be had at a bike shops. The second stuff is professional stuff found at auto body shops. I've used glass and resin and it wasn't very strong. Not the resin itself, but where it bonds. Your bike doesn't have fiberglass, it's ABS and the resin isn't made to bond to ABS.
#5, you'll have to snap a picture of. I don't really understand what your talking about.
#6 I have loads of them. We're talking coffee cans full. WHich ones do you need? I have lots of the common ones, but only a few of the hard to find stuff. I can give you anything I have enough of.

i havent really screwed with it, just took the filter off.   but it starts fine always in warm weather... when its cold though, man it will take forever.   also the longer it sits the harder it is to start.  just recently it sat for a week or more,  cold weather and it wouldnt even come close to starting.  but i only tried for about 30 seconds.  

dont know what a sir filter is...  its not off unless its always been lol.    speaking of filters (maybe thats what it is)  whats the orangish spongey type filter thing thats connected to the air filter box, left side of bike.  its pretty small.. maybe 1.5inches x 2 in.   give or take...

i dont think the bike was jetted...  though not sure on that either.  everything so far is stock though.  any easy way to tell if its jetted?  

and as far as fixing the fairings.. i only know 1 shop around here that does plastic welding.  dunno how good  they are at it.  i also wanna get the bike repainted so what would be a nicer/cleaner job?  usin the plastix or fuser stuff? or getting it plastic welded?

well what i see now...  i need 2 fairing screws *the ones u need allan key for*,  2 nut/bolt screws for the center front of the fairings behind the front wheel.  need 1 front sprocket gaurd screw.  and im gonna have to grind off 2 bolts that hold on the seat cuz they are stuck on and stripped.  i had to get the seat off by squirmin my hand up under the rearsets and loosening up the smaller nuts that hold the seat on.

as always, thanks for all the help

Sir filter is air filter. And the other thing is a little breather so that  the oil you found doesn't just drip all over the place.

how does that breather work???... i didnt bother with it much, all i noticed was that it had a rubber tube running down to the engine (or toward it).  

do you know any way to get rid of that starting problem?

The breathers comes out of the crank case. It prevents pressure from building in the case. Since the air that comes out is oily, the thinking is to vent it to the air bix so that the oil can be sucked back into the motor and burned. The little sponge is there so that the oil comes through and comes in as a mist and not in big droplets. As for your starting problems, I gave you some things to look for, but I can't do much more. It's a tough call via e-mail. I'd need to actually see it and hear it to get too specific.

well,  if there is some sort of build up in a carb.. u think this is a job i could handle?  ive heard mixed opinions on messin with carbs or would cleaning them be easy?  

i really dont got the cash to take the bike to a shop and i dont mind rippin her apart... got lots of time. winter isnt fading anytime soon heh

thanks man

I regards the the plastic welding, like I said, it usually won't look real nice around the weld when it's done but it will be just as strong or strong than before. A good body shop should be able to work wonders on the fairing since the stuff is soft and easy to work with.

As for the carbs, I myself don't like messing with shit like that. That is something that can get totally screwed up if your not careful. Better left to a professional in my opinion. That way if he screws it up then he has to fix it.

If it's just dirty, then it's something the home mechanic can do, but it would be a fairly skilled home mechainc, not a putz. I would hesitate to tell you to pull the carbs off the bike with the little information I have though. It could be something else. Plugs maybe. Do you ever start the bike up and let it sit and idle for a long time?  There wouldn't be a build up unless the bike has sat for a good long time. If that is the case, cleaning the carbs consists of removing them, taking the bowls off and removing the jets and cleaning them in Gumout, and blowing through the carb passages. If this sounds like stuff you feel you can handle, then give it a go. But, go and buy a service manual, (Honda, don't buy a junk clymer or Haynes). This isn't something I can easily talk you through in the space here.
