Q:How do i use a valve spring compressor. It looks like a c-clamp, so don't tell me how to use a smaller one, but the bigger one.Thanks

the forked end of it will go over the spring part and the solid will work on the valve ,you can only use this one if the head is off though,the smaller ones work good if the head is still on the car,the c-clamps style though is the best one to use its safer and wont allow the springs to fly off,good luck.

Q:Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.

Support many 3D CAD format, such as the commonly used UG, Pro/E, SolidWorks......As for the butterfly you said, don't post the link up, the standard JIS, American Standard ANSI, German standard DIN are.You use Baidu Search "LinkAble PARTcommunity", after the open registration, CAD format, such as UG, ASAHI and then to find the manufacturer home page, which is the valve, you said the Japanese standard, German standard, American Standard valve basically all.

Q:What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?

1, the drive mode is different (handle or turbine), mainly based on the size of the valve and the opening and closing torque to decide.2. The butterfly plate of the worm valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees ~90 degrees between, when rotates to 90 degrees, the valve opens the card completely.3, clip type butterfly valve is to use double headed bolts to connect the valve between the two pipe flanges, flange butterfly valve is a valve with a flange, bolt with the valve flange at both ends connected to the pipe flange.

Q:My bike has now 6200 miles on the odometer. The manual says that a valve adjustment should be performed every 6000 miles. But the bike runs fine. Can I just have the valve checked or should I have them adjusted even though the bike is fine? What will happen if I just keep riding it?

First off you are suppose to take your bike back to have your valves adjusted after 500 miles. Anything later can cause problems. The motor is already broken in. why did you wait so long to have them adjusted ? Your vibration is the tire is not balanced right , take it else where. good luck
