Front fork seals size, please - 2005 Beta Alp 200

The easiest thing to do is find another bike that has the same size internal fork seal size as yours.for instance yours may have
41/54/11 fork seals and a Honda cbr 600 May have the same or 41/53/8 so as long as the first number is the same the actual forks will fit your yokes.is yours a cb400f project big one ?

Your triple clamps are the best vice for your fork tubes. Put your bike on the center stand and lift the front wheel off the ground with a jack. Take off your front wheel and loosen the socket caps in the bottom of the tubes. ( you may want to remove the front fender to work on tubes individually) On some models you have to put a towel on the tank, unbolt the handle bars, and move the bars enough to get them out of the way. Unbolt air crossover tube if equipped. Loosen fork top caps and remove. Place a pan under the forks and remove the socket screws. This will dump the oil and allow you to remove the fork lowers. You may need a seal pry bar to remove seals. Installation is reverse order . Add oil after snugging up socket screws ( tighten after top caps are on). Do not to over fill fork tubes with oil it will damage the fork sliders while you ride. The dealer can tell you the correct amount for your model. Honda dealers have pocket size specification books they get quick check the information.

Each fork has an outer dust seal, and an inner seal inside of that. Dirt gets between the seal lip and the fork slider and causes the oil to escape. The fix is to have them (Both sides) replaced. You need a fork seal driver tool (Size specific for the size of the fork) and something to measure out the oil amount. It's not an easy job, if you have never done it. Also... if the oil has never been changed, it's due.

To replace the fork seal you must open the top of the fork and remove the spring. Then drop the fork tube out of the clamp. Once the fork tube is removed replacing the seal is simply pulling the old one off and putting the new one on. You will need to remove your front wheel.

hi non usd forks are ok thers a allen key bolt at the bottom of the fork leg would be wish to change the fork guilds too thr fork seals can be prized out with a screwdirver carfully

You have telescopic forks on that model. A telescopic fork on a honda or a suzuki or yamaha are basically the same. The main thing you need to know is fluid level. If you've never done it before , please leave it to the professionals only because that is a major oops if it's not done right and could kill you. as far as the missing, it sounds like you need a carb clean ( if it applies to you unit ) Your slow speed jet gets clogged very easily on the *** models because the inner size of the jet is tiny. If you didn't store the bike with stabil or if you've left gas sitting in the tank and carbs ( if applicable ) for longer than 3 mo's then I would do a carb clean. If your model is Fuel injected.. You mat have a bad fuel management system ( Power Commander, Fuel pak etc... ) try unplugging it to see if the problem clears up. if you don't have am aftermarket fuel management and it is a stock bike with fuel injection, then I would suggest bringing it to a dealer to see if there are any current or historic codes in the bank.

This all depends on what size forks you have, but a good rule of thumb is 120ml. After that then what you want to do is to ride the bike and make adjustments to your front end until your liking.
