Re: Down one tooth on the front sprocket - agricola - 11-01-20
Given the 6.3% loss of speed for the same revs, the calculator gives me 28.11mph at an indicated 30mph, 37.48mph at an indicated 40mph, and so on. In reality, on the roads, I shouldnt really have to worry about speed cameras, more like holding traffic up

New front sprocket on, thorough wash and dry, cover up the front wheels etc, and spray ACF50. Last night, in the garage and cut the fairings down so that they don't drag the tarmac and try to lift the rear wheel off the deck. The look is going to have to grow on me, not sure if i've done the best thing, but hey ho

I think they look sound,and anyway they're doing a job so it don't really matter.

I moved up to inters last year on the track, and I rode faster as a result. while the fazer has very decent braking and allows me to brake later and harder than others in the group, those same bikes simply blast past me out of the bends. Id like a little more punch out of the corners, hence the thought of going down one on the front. It appears it would give me +6.3% on acceleration, but -6.3% on top end. Since the bike cant get to the top end before the end of the straights,m I don't think Ill miss that loss, and the acceleration gain will allow me to get there quicker.
I'm also either going to have to mod the fairing lowers, or leave them off. After wearing a hole in them leaning over, i fitted replaceable slef lube nylon sliders, and wore them too, so I'm thinking off cutting the lowers and fastening them somewhere higher up the machine, but Ill lose the edge return at the bottom of the fairing.
Any thoughts anyone?
Lower gearing makes it more convenient for in-city traffic. Less often being necessary to shift into the 1st gear. I like it.
Having said that, the front sprocket is small enough already. Good option could be adding a larger rear one. Larger sprockets seem to last a bit longer.

might you get a problem with chain length then though? going up on the rear.

If not changing the existing chain (using a new one and cutting it to size)? Most probably. Especially since getting the desired gearing by using a larger rear, requires more than 1-tooth difference.
Good point.

Yep agree. The smaller front sprocket shortens chain life by lessening the radius it travels around, but it's the cheapest most instant fix. When it's chain change time I'd rather go 3 teeth on the back sprocket if lower gearing was needed.
Re: Down one tooth on the front sprocket - agricola - 03-02-20
Chain length may have been a problem had I gone up at the rear instead, but going down at the front just took up the slack by a couple of flats on the adjusters
Re: Down one tooth on the front sprocket - agricola - 11-02-20
Modded (chopped) the fairings last week, finally got around to fitting them tonight. Looks ok I think. should certainly give me some more ground clearance now
