OHV and OHC Engines:
I agree OHC is more refined than a OHV engine. OHV engines like the engine of CG has push rods with creates more vibration at higher RPM than OHC engines. OHC runs smoother and has more precise timing because of its less moving parts. Thats the positives of an OHC...... now lets take a look at the negatives.......... OHC has a bulkier head thus increasing the height of the engine, which means higher center of gravity which means worse handling. But thats not the deal breaker....... the real deal breaker why OHV engines are so popular in Pakistan is because they are more robust than OHC engines.....specially when they are running on low or heavier engine oil. This has been my point since the beginning....... we are not ready as a nation for new technology. Generally we take no or few preventive measures as bike owners.......Honda developed the CG series for this very reason ppl..... we are not good bike owners....we abuse our bike more than that or bikers of developed countries. OHV engines suits our weather....... our mechanics know how to mend them........these engines are more robust....they are cheaper to fix as engine components are easy to work with.
We always bad mouth old technology and designs that are still in use here......like CD70, Mehran, suzuki Ravi pickup.......... have you ever thought why are they still the same....because they are not cars......or motorcycles.......each name represent a industry in Pakistan. Mehran and cd70 is not just a vehicle......they are industries.......you can buy everything for these machines and they have several after market manufacturers. Its not that easy to change the whole industry...masses buy these products because of the aftermarket stuff........thats why they are still the same.
Yes CG engine vibrates more than GS engine at higher RPMs but thats a trade-off for being more robust and cheaper to repair. And BTW OHC are suppose to produce more power however geniuses at suzuki made the GS OHC engine 10% less powerful than CGs OHV engine per displacement volume. So basically all the goodness you get from GS OHC engine is less vibration. I don't know whether this is a step forward or a step backward.
Almunium Engine Block:
I honestly don't know what is CG engine block made up of but it has passed the test of time. Even if its not aluminium it does not melt, or lose shape.....or disintegrate.....they are just fine.
Oil Filter:
Taking the pollution and dust into account fuel and oil filter are a must.........or are they?
OHV engines can work fine without an oil filter that's why they don't have them. On the other hand OHC engines requires Oil filter to ensure oil gets to every moving part the top of the engine because these engines have higher heads than OHV.
Having an oil filter doesn't make GS superior.....it simply points out it fragility.
CG.....Poor man's Fire Blade:
It is.......CG is the poor man's fireblade. Its fast and it brings a smile to your face.
and that's what make the bike great. Im sorry to say but GS really really lacks here.
Point A to B:
GS is good...... its smooth.....its comfortable....... its a bike for someone who wants to get from point A to point B respectably . It serves well as a daily commuter. and That's it...... Its not a looker......its not just as fun....
