The lowdown : Old scooter's with K and N's

K and N are known world over for their high performance air filters , a large number of guys are fitting vehicles of every type with k and n filter . Me being a shallow pocketed Indian went for the K and N look alike air filter and got it coupled to the 100cc 8bhp two stroke 1990 model kinetic honda .
The pick up has jumped and growl is like music . Mileage has not dropped appreciably . Trouble is two stroke engines get heated very quickly with a filter (My kine gets sweating as quicly as 3 kilometers) . This is because the compression ratio has increased two fold . One of the easy options (i have talked to numerous mechanics in Bangalore) would be to increase the viscosity of the fuel . Other options include getting a smaller fuel Jet , Fitting the filter inside a box (both of which spoil the filters effect) . Increase the ratio of 2 stroke engine oil from 20ml per litre to 60ml . That way your engine will keep calm for a longer time . I would like to add that this problem only plagues two stroke engines . Four stroke have no known side effects to filters .
