Adding three teeth to the back is the same as taking one away from the front sprocket. I usually like two extra on the back as you rarely need all the top end speed available. To save your bike mechanically and preserve yourself it is alot safer and kinder to your bike to clutch it up. After all your clutch is a wearable item and your headstock isn't. All bikes are different but at just below half revs in a resonable gear (2nd) slip the clutch as you roll on the power. Hard to explain as the sound is more descriptive but you are not trying to seperate the clutch plates totally but instead release enough pressure to let them slip and you'll here a blip in throttle sound and a jump in around 1000 rpm. Front should come up nice and smooth whilst you cover the rear brake incase you ham fist it. At about 45 degrees the bike will reach it's natural balance point where it will sit quite happy with little imput. Be sure to allow the front to lower and then wind on some power to put the front end down gently. Snatching at the throttle to shock the front up only does your cush drive and chain in.
