husky sport are really good though sometimers to order parts it takes ages, if you want any call up parts and speak to reeese he's really funny on the phone. Well spark plugs should last at least a few thousand miles on the road if the bike is running properly, the problem with two strokes is that if you don't have enough higher revs the bike will clog up the plug, ie it'll not fire properly and will look black on the tip, you need to rev it hard as much as possible for it to run right, they're simply not made to go along at constant throttle. If you get the jetting right the spark plug tip should be a brownish colour, properly black would be too rich a mixture or not enough revving, white would be the bike is running lean or hot ie too lean a mixture, too much air not enough fuel, that will blow your piston into pieces. Unscrew it and check the colour, also check the wire that connects to it, if that's no good you won't get a good spark through. The oil pumps are fine but you need to keep an eye on it, I didn't and mine broke and locked the back wheel up hill at 50 mph, nearly threw me off, they're about £60 from husky. I know you won't like it but it's much better to premix the fuel to be certain you get the two stroke oil through[ use a good quality one btw, cheap oil isn't worth the engine rebuild cost, I use this,

If you look down by the kickstart on your bike you'll see the throttle cable has split into two, one goes to the carb the other round and down into this little housing, there's two bolts, if you undo them you can see the cable inside that attaches to the oil pump and hopefully the oil too going up and out the pump. Also check the tube that's coming from the oil tank under the seat, that goes down to the pump, you don't want that leaking or getting blocked! If you decide to dissconnect the pump and run premix go with 35/40 to one max, that's 1 part two stroke oil to 35 parts of fuel. The oil is important as two strokes get their cranks lubricated by it , no oil means bottom end failure/ damage. Maintanence wise, I'd get a new air filter on yours, they're about £10 on ebay, undo the seat with the bolt at the back, pull the cage off by undoing the nut that holds it in place, then put the new filter on after putting some oil on it, oil stops the dirt getting through and into the engine. I clean miine maybe 500 miles or so or replace it for the cost of it. The gearbox on these is very good since it's the same as the wr/cr bikes but I change my gearboix oil every 800 miles, since I ride it so hard, there's a little but underneath the bike, take that off with engine warm, drain it into a bowl, tip bioke both ways to make sure it's empty. Put in 730 mililetres of oil [should be same as mine] then hold the bike upright and look at the glass hole on the side, if it suddenly covers over you have enough oil, if it doesn't cover over with bike upright, you need more oil. I guess you should also keep the clutch cable with a little grease to protect it, do both ends, dirt will break them quickly and they're not cheap, £18 for a venhill one or £20 ish for genuine. I can't think of much else but do come back and tell us what colour the spark plug tip is, it shouldn't be eating them if the jetting is correct
