You will need a variety of shims, and the valve bucket holder tool to adjust the valves, but i find it hard to believe that you would need anything at this point. Just pop off the valve cover and check the clearances with your feeler gauge. I'd bet they are fine, unless theres a valve seat issue-

95 acura legend, if I install a air separator tank thru the bleeder valve to relieve the trap air ,will it affect the thermostat operation?


Let me guess. Some mechanic told you to do this to your Legend? :-)
Do not do this (if it's even possible)

The simplest thing you need to do for the Acura Legend is to bleed the coolant system to get rid of the trapped air.

Legend race car 1250 yamaha. Put new carbs on it.Acts like it is starving for fuel. Will run with choke partly on.But still spitting back and popping through carbs.


lean misfire... you need to make sure the float bowls are filling up with fuel. I suspect a fuel flow problem... might need a low pressure low volume electric pump

How do i set cam position and timing on an old yamaha xt 500


You didn't say WHY the cam / valve timing needs to be reset. For some reason I get the feeling someone told you that resetting was needed and so you are asking how. Obviously, you may have installed new pistons and that is why the resetting is needed. In either event, when the cam timing is set the valve timing is also set. Other than adjusting valve lash, setting the cam sets the valve timing. Below is a web site where you can do a free download of a factory service manual. The process is not hard but having a manual will be more help and faster help than I can give online.

I want to significantly power up my 1996 Yamaha Royal Star 1300. I've been told that putting racing cams, dual valve springs, a performance kit should do the trick. I'm obviously not a builder. What...


Race cams do increase power, but reduce mileage and don't idle as well. Dual springs prevent float at high RPM, but it is not clear you want to rev that high as they do in racing. By performance kit, I assume the idea would be to cause ignition timing to be advanced more when accelerating. This will take advantage of the valve opening overlap from the race cams, but may require premium gasoline to prevent pre-ignition.
Technically I think you can do this without even removing the head. But it may be easier to remove it. And then it may be cheaper just to go with a larger bore or larger valves. If you don't have the tools for compressing the springs, then you will have to take it in anyway, in which case you can get their opinion. But it is within the capabilities of most home mechanics that understand how to replace a timing chain. You have to keep the crank and cam in correct synchronization. If you don't know what I mean, then don't try it without reading up on camshaft timing.

Did you try to increase the idling adjustment screw?
Check the spark plugs for its condition and thn reset the air-mixture screw.
Standard procedure for setting air-mixture screw...tight it all the way in, taking care to not over tighten or the tip of the screw may be damaged, thn turn outwards 2 & half to 3 turns, start your bike's engine ,run it to normal temp. and the reset the screw + - alittle either way and you should notice the difference in the idling and all.
Its better too, to also check the valve clearance !
Hope this helps!

My engine races upon starting, as if my throttle sticks. What gives? It is an 03 YZ 250


probaby settels down after it warms up a bit :-) pull the carb off and check for a cracked reed valve clasic problem with the old boyseen dual layered valves.
if not check that the carb is well sealed in the neck going into the engine a little air leak will give the engine a runaway effect
ride safe Good Luck

Hey ljthomp6_30,
I would just reset the flash back to the manufacturers default setting, which is done by pressing the mode button and the on/off button simultaneously for about 2 seconds. Keep in mind this will also reset any custom settings you have. In case you have lost your manual I have included a link to a PDF download of it, and directions on how to reset your flash are on page 12. I hope this helps!
