combustion chamber ka area 2 strokes ma bar saktha ha . laikin us sa compression kam ho jaya gi .. jis sa maza nai aya ga .. kam bhi ho sakthi hogi kionka koi valves tho hothay nai 4strokes ki tara .. chamber ma weilding karkay area kam kartha hain goray ... local ka nai patha ... area kam karna sa compression bar jaya gi .. jis sa maza atha ha ..
head grind ka tho nai patha kia matlab ha ? if it means to resuface a warped head then yes it is done to both 2 and 4 st.. some ppl may grind the head to increase compression ratio ..
