with increase compression let us know how have you increased air / fuel mix and whats your cam profile now. otherwise its obvious it will knock.

fine tuning u made CR sound so simple

Hi,

Better utilisation of high compression without knocking is one of the major benefit of grooves......neither cam profile is changed nor porting to increase flow of air.....this project as usual was carried out with simple groove work...I think if this can be added together with grooves will make a much more difference....but simplicity of this technique lies in not touching any other parts like camshaft and valves.....i think its beneficial for common people this way only....

Here is a link showing excellent benefits in old Kinetic Honda...

Enjoy....

heard in another forum that a guy actually rebore the engine from 150cc's to 195cc's.
Dunno how he managed but he has done it 3-4 times now easily.

so certainly u will have to use higher octane petrol right!!
increasing compression with stock internals would lead to reducing engine life. whats ur take on that.

Hi,

With grooved engine head there is no need to use high octane fuel....normal octane rating is sufficient to pass on benefits......increasing Compression ratio with grooving is a novel approach of using high CR without detonation & without using high octane fuel......

Again increasing CR with grooves infact increases useful life on engine.I came to know about Esteem driven 3 lac Km after grooving by Somender Singh.
