Motorcycle Tire Valve to grinding, normal conditions, the valve does not need gx125grinding, and the exhaust valve is used to wear small, normally also is often to see the bright ring, are in red or black carbon covering surface.

If need to grind the early chemical type from October 24, 2010, normal to quietly remove accumulated carbon, then being valve and valve seat painted a little oil, the coarse grinding coated are above, the valve opens into the cylinder head, with special grinding machine or manual and repeatedly rotating grinding, strength is not too big, and regarded gradually for fine grinding, polishing after thorough cleaning cylinder head, valve.

If the valve or the valve seat wear greatly very rough contact surface of zero or too wide and other serious wear, need to use valve reamer for reaming Motorcycle Tire Valve cut, it must be made by the professional repair staff.

If only the valve itself larger wear, also can change a valve, now it is not expensive, but also better, and Suzuki king or drill leopard those cars similar models are the same.

Valve reamer reaming is necessary in accordance with the condition of being sequentially with 75 degrees,15degrees and 45 degrees in order to replace the reamer reaming, that even ordinary motorcycle repair personnel can do, not simply a few words can say clear, but the normal motorcycle as long as grinding valve on the line, rarely necessary reaming valve seat, do not know your car wear to what Cheng bottom, but can change a valve on the line, if not being grinding or using external damage to the valve seat, unnecessary reaming, the work does not even without things do-it-yourself, damaged cylinder head is poor.

Motorcycle Tire Valve clearance to use how long will become larger, the accurate standard, but in general the use of frequency and big cars, are also relatively easy to larger gap.

Motorcycle Tire Valve  larger gap may have a larger may also have two bigger.

3 no valve will be easier to change, but it seems the intake larger quicker, valve clearance is a more cou crisp rapping, intake valve and exhaust valve clearance gap bigger bigger sound is the same, not only the voice heard is which problem, must after the examination can be determined.

4 in general, the inlet valve can exhaust slightly more, but in fact, is the tune into a standard, the top rod machine valve clearance, in 0.050.06, up to a maximum of 0.08, but the general adjustment of time by handle, left and right space, may be free to move on, no gap can be. On the positive piston ATDC (must be the TDC, namely to the positive of T point, around light and magnetic motor two valve should not move), a two valve can be a good tune, without the need for a two timing, but adjustable valve, preferably the magnetic motor rotor two weeks back to timing and test it again valve clearance have the change, so the accuracy is high.

The push rod machine car, clockwise and counterclockwise no difference, but for some camshaft decompression mechanism on the engine, magneto is a must to turn counterclockwise, it may cause the valve clearance is not correct, however, no matter what kind of engine, preferably both the counterclockwise rotation of the crankshaft.

World rubber industry, especially the rapid development of China’s tire industry for our Tire Valve core provides a steady flow of orders. Valve core of the industry to seize the development opportunities, product variety and quantity in recent years, continuous and steady increase, the main valve core product categories account for the output of more than 70% global share, becoming the world’s largest producer of valve core. Valve at the recently held general learned the core industries, output in 2010 will exceed our valve 3 billion, will exceed 3.5 billion valve core, valve core will account for more than 85% market share.Industry enterprises have reached a consensus: should not revel in the production of hegemony in the world on, but should correctly understand and face the problems the industry, improve quality, eliminate hidden dangers and do a responsible “world business. ” China Chemical Equipment Association Professional Committee of the valve core Li Dongping that the valve core in recent years, exports of the number of varieties grown rapidly, the core business of most of the valve more than 60% of products sold in international markets, and gradually entered the international Auto parts procurement system. China has become a truly world largest output valve core, the largest production base for exports.This course is a happy event, but must also see that the momentum of our strong export valve has shaken the core of the existing pattern of world trade. Hand, in this case does not dismiss the possibility of some countries for the purpose of trade protectionism, by building out a variety of barriers to prevent Chinese products, manufacturing, international trade discord; the other, the individual is more awareness of domestic corporate social responsibility Weak, and do not pay attention to product quality, and blindly compete for market at a low price in the international market have a bad effect, this situation will inevitably lead to some exporting countries to use international trade rules of the game, to carry out the quality of export products to China and even anti-dumping investigations .He believes that in order to ensure the healthy and stable long-term development, China’s valve industry, the core must be the case in the situation is excellent, as the valve shoulder the responsibility of the core powers of control world power shortcomings, bad behavior to discover the industry, regulate trade order. He suggested that enterprises must improve quality from the start, Lianhaoneigong to promote technological innovation to improve the quality of products; from the beginning of a brand name, expand markets, reduce the risk of dumping; performance and social responsibility from the start, being a responsible “world Enterprises. “It is understood that the main origin of valve concentrated in Jiangsu, Zhejiang, Shandong and Fujian, has formed a complete specification, supporting a structured pattern of industrialization; more than 30 manufacturers, the annual output over 300 million have 4 , over 5000 of more than a dozen. Estimated 2007 sales of various types of valves can be supported to reach 2.19 billion units, with sales of 40 million yuan or more. Among them, the truck inner tube valve 120 million, motorcycle, bicycle inner tube valve 1.2 billion, truck tubeless valves 40 million, car tubeless valves 800,000,000, and other special valves 30 million.Leading products truck inner tube and Tubeless Valve, Motorcycle Tire Valve, tubeless valve car production have been about 70% of the world, exports amounted to nearly $ 250,000,000. It should be noted that the valve core and the National Rubber Machinery Committee of test center quality earlier in the investigation of the industry, we found a number of negative phenomena and potential risks. For example, the Tire Valve problems are: the persistence of some enterprises Material mainly the mouth lower and lower copper content materials; change valve standard structure and size, to reduce material consumption purposes; valve Mouth and body size, short, not up to standard requirements; mouth thin body chassis, small diameter.In addition, the rubber valve seat materials, poor quality of rubber, metal, plastic body cover low, the prevalence of blooming phenomenon. Valve inside the main problems are: some enterprises material is mainly the valve core length shorter than the standard, resulting in valve core leakage rate, some enterprises valve core leakage rate of more than 5%, life is short, inflatable speed Low; Snap valve factories in the Ningbo region there is some use of cheaper natural rubber and recycled rubber mixing, instead of EPDM rubber and natural rubber mix, the product can not be tested through the ozone standard; some companies to reduce the valve Copper mouth to save weight, without changing the structure of valve size standard, such as the diameter of the mouth bar and the core chamber reaming thinning cancellation.National Rubber Machinery Quality Supervision, Inspection and Shen Jie, deputy director, said valve core is related to people’s lives and property safety, whether national standards or international standards are the size of the valve core strict requirements, without changing the product Structure size is actually illegal. If a large number of non-standard products are exported to foreign countries, the vehicle after installation will bring great security risk. Tubeless Snap-in particular, valve, mounted on top speed of over 200 km of the tire, once the accident, will be the car crash of major accidents, the reputation of Chinese products would bring adverse effects.He suggested that industry should pay attention to standard adoption problem, companies should self-examination, and resolutely put an end to production of non-standard products, producers have to crack down on individual non-compliance and the media exposure.
