Do I have to remove the carbs to change the plugs on a Vstar 100

Clymer has me removing most of the top parts of the engine. I jsut want to make sure I have to follow the entire directions or does someone have a short cut. It seems like a lot of work to go through every 5,000 miles

I'm trying to change the speedometer light on my Yamaha VStar

Perusal of a parts manual shows the bulbs to be in sockets with wires hooked to them which press into the outer back of the speedometer head, remove the offending socket (the one on the top, the other 4 are the function lamps I previously mentioned) by gently pulling it outward, the bulb will slide out for replacement.
Have fun and good luck.

One carb does not want to fuel on low revs ie remove plug lead from good pot on low revs it stops remove plug lead on good pot with revs it wiil run remove bad plug lead on low revs makes no change to...

Sounds like you need to remove the carbs and dismantle them and clean all the parts real good.
Remember if you separate the carbs from each other you will need to resync the carbs.

My outboard mercury has been sitting several years now. Now it seems to be getting too much oil into the engine. And not enough gas when I try to plane out. Is there a gas-oil mixing valve befor the...

your engine is fuel injected the fuel system is clogged with bad gas. fuel is proven to only stay stable for 60 days. after that it begins to turn to varnish. I can lead you through the repair easily, but i do suggest you go to this website to get picture diagrams so you can see how the engine parts are lined up. upper right had corner of page click search with pictures. select product line. select column Mercury, force, mariner and other outboard select mercury mariner scroll down to V-150XR1 next page. verifiy the serial number then click on it. ok now you have a list of picture, discription and part numbers to view. TOOLS (1) A compression gauge (2) a spark gap tester.(3) A Clymer service manual for your engine. (you can purchase from your local dealer. I know all these are expensive but if your going to be a outboard owner you will always need them. TROUBLESHOOTING (1) check compression. I'm giving you a average numbers. Look at your Clymer manual for more specific numbers. all cylinders need to be over 100 lbs and equal each other within 5 lbs. If you have good compression (2) check spark. use a spark gap tester, all cylinders should jump a half inch gap.replace spark plugs, I know spark plugs probably don't look bad but this is a outboard. Fresh spark plugs means less resistance for the ignition system. The ignition system is week compared to automotive.(3) Replace all fuel filters. there may be one on the boat. there is a fuel filter under engine cover on the starbord side replace it. Test drive boat. I know it is time consuming but I am making sure you don't spend time and money when you dont need to. If problem is still there (4) the fuel filter you replaced under the engine cover follow the fuel line to the vapor seperator.(website fuel managment system breakdown reference numbers 21-25) (5)on the bottom of the seperator is a hose leading from the fuel seperator to the electric fuel pump. NOTE, what i want you to do is verify fuel is getting to the vapor seperator and to the electric fuel pump. because there is a needle and seat in the vapor seperator and a filter in the hose that stops up. NOTE the filter in the hose (reference number 48 on website)make sure you remove hose completely and check by blowing threw it(6)with hose removed use primmer bulb and force fuel into the engine. fuel should pour through fitting that the hose was connected to. If not we have more work to do. I'm hoping you filter is stopped up in the hose. IF THERE IS FUEL FLOW AND FILTER STOPPED UP put everything back together with new filter and test. if no improvement you have pressure test to follow in you clymer manuel. follow each step about fuel pressure test. you are testing the electric fuel pump a $600.00 unit. IF NO FUEL FLOW FROM FITTING and hose filter replaced( why put the old one back?) (7) You fuel vapor seperator needle and seat is stopped up. refer to websit pictures. reference numbers 23 and 24.(8) there is six screws to remove the top of the seperator. a o-ring that can be saved but i would suggest ordering a new one.WARNING float level is setting is critical be careful not to bend float or rod(9) Remove float and needle and clean seat thoughly with carb cleaner. use primer bulb and pump fuel. Does fuel flow? if yes replace needle and float and use primer bulb again. gently close needle by pushing on the float. you should be able to stop and start the fuel flow with the float and needle. if you have any worries order new parts.(10) after you have verified fuel flows and stops through needle and seat. look inside of seperator housing is there any sedement or varnish. IF CLEAN reasemble vapor seperator. IF DIRTY the vapor seperator also receive oil from oil pump at the bottom of the seperator look for hose and fitting. make sure oil fitting is clean if ANY DOUGHT ABOUT OIL DELIVERY REPLACE VAPOR SEPERATOR YOU CANNOT GET THE OIL VALVE SEPERATE IT COMES IN A KIT. ok I have taken you through the basics everything else is in the Clymer manual you need to purchase. good luck

Idles great in gear no power

I could not find a free download. You can go to and probably purchase a manual there. Also Google "motorcycled repair manuals". If at all possible, only get a factory service manual. Haynes and Clymer are not nearly as helpful. Gas/oil mix should be 32/1. That's 4 ounces of 2 stroke engine oil per gallon of gas.

ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a plug on the bottom of the carb float bowl. Remove the plug then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Pay special attention to the main jet. Check the main jet, the stock jet is #360. Remove the idle screw on the outside throat of the
carb and also the air screw on the intake where the air filter attaches. Spray into the screw holes as well.
Be sure to put these two adjusters back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the slide back in the throat of the carb but move the clip on the jet needle to mid-range. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. If the problem is still present, remove the exhaust pipe and try again. The exhaust could be restricting the flow of burned gas out of the cylinder. The only other thing would be the crank seals. Post a comment to get back to me.

Trouble removing carbs on 96 CBR 600 F3

Theres a big lip holding it. Make sure all cables and pipes/hoses are removed, spray with some WD40 or similar spray lube and then try prying it with something that won't damage the carbs or engine.
