Dear @saboor73,
would you kindly keep your 'VERY SANE' ideas to your self or on some other threads please ? where you distribute your SUPER knowledge all over the place, I already deleted your few "VERY HIGH INSIGHT" comments and before deleting this one I thought to let you know that please stop posting we dont need them really .. and you know it already dont you ?
The reason is that you have been thinking SO PRACTICALLY(GOD FORBID) that "a picture for reference" and an OHC "chain driven" 250cc engines looks like an OHV to you so there is no more need to baahas with a guy like you, who's knowledge is so poor that he dont understand the difference, and beside he has been stopped and bashed really hard but he is so "KNOWLEDGEABLE" that he comes back with his FANTASTIC idea back...
please abide by this time..
Warning & Thanks.
