What is the compression on the cylinder compared to the other cylinders? It should be within 10%. Some causes can be - as you suggested - the valve stem seals. Also, the sleeve could be rusted, as the valves could have been open on that cylinder. Generally speaking, on a 4-cylinder motor 1 cylinder has both its valves closed, 1 has both open, 1 has an inlet valve open and one has an exhaust valve open at any given time. Another possibility is that the valve could be sticky - try Wynn's Valve Ease or a similar product.

Bike sat for a year. Started up and fuel spilled everywhere


Hi, Anonymous if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and replace the battery.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove your air cleaner and clean and re-oil per Mfg. specifications.
6. Remove the carburetor, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove fuel lines and replace with new ones.
8. Replace spark plug with a new one and check for spark.

Will not start..i pour gas in cyclinder and trys to fire up..it set up in storge a long time


carbs have to come off and be completely cleaned and if your keeping the bike i would order carb kits and rebuild them while you have them off. the good thing is that when you are done the bike will likely run fine. when gas sits over 18 months it becomes a varnish like substance than plugs all the jets and the needle and seat. good luck. if you havent done this before get a manual and takes notes as you tear the carbs down and pictures if needed. if you take enough notes and dont let the job sit unfinished too long you should be able to do this without any problems.

It just wont start. it sat for about 3 years. i got it started after new gas,oil and removed the air filter. it only ran for a few minutes at high idle. then backfired throught the carbs. now sometimes it...


Gas will turn to varnish in as little as 6 months.
The new gas was just enough to get the varnish nice and sticky before it started giving you fits. There is noway the carburetor will function correctly after 1 year let alone 3 without maintenance on the carb. This will require the carburetor to be removed and completely disassembled and cleaned. This is not rocket science and with just a few tools and a bit of skill anyone can do it. However if you have never done it before the very least you need to do is get a service manual. It will give you a far better explanation of the task then I can give here.
Hope this helps.

Adjust spring preload


There are no preload, compression or rebound adjustments on either end of a 1996 Royal Star. The front fork characteristics can be changed by internal modifications to the front fork piston and a change in fork oil weight (stock is 5W), lengthening the spacers immediately beneath the cap bolt, or addition of progressive springs. The rear shock absorber assembly is a unit with no serviceable parts, no modifications are practical. The only aftermarket suspension parts I've found for the 1996-1998 Royal Stars are kits offered by Hyperpro (ECM), they list kits for the front forks SP-YA13-SSA05 and the rear SP-YA13-SSB05; however, since the rear kit is purported to fit all years from 1996 to the present, and the rear suspension was redesigned for the 2002 model year, I suspect that you may find that the rear kit doesn't work at all.

Carb problems


if & when you do get it running again, does the bike have a petcock at the gas tank? if it does, when the bike is running before you are about to park it for 2 weeks, turn the petcock off and let the bike die on its own (from fuel starvation). this will ensure there is (almost) no gas in the carb to cause any gumming. you can drain the little bit that is left with the carb bowl drain screw. then when you're ready to ride again, simply turn the petcock on, wait a few seconds for the carb bowl to fill, then hit the start button.

Idle problems


Hmmm... this doesn't sound like a problem that belongs here... By "cuts off" do you mean stop running, or misfire? Carb. problems often are the result of the bike having set for many months or a year or two with old gas, which can result in a varnishing like of the fuel in the carburetors, which can clogg small passage ways, and subsequent no-idle, or other poor fuel delivery. Problems such as this require repair by knowledgeable mechanics. Other things which can upset correct fuel/air mixture are modifications such different exhaust system, air cleaner change, camshaft- any mod of these can require some retuning.
