To all,
I do realise the difficulty in answering a question like this, considering i don't give any data about the cilinder in question.
I have done some math on the cilinder in calculating blowdown?Ta's etc and what i came up with is that the blowdown, compared to major bike brands, is minimum. Blowdown with open exh valve is 28 degrees, so with closed valves even less. Is it safe to say that this cilinder wld benefit with faster scaveging? I wld almost say this cilinder is made for low-end was it not so that the aux ports are angled towards the exhaust rather steeply.
This is a 99 cilinder but as everybody knows the design is not changed in all these years and nowadays everybody raves about the wr125 huskie, although this is a cr but cilinders are the same.
And Marcus don't say again that this my project from hell, pls....
