I have just purchased myself a vee. Bike drives nice, but couple of small issues. 1. front brakes are really poor (how do I make the brakes better)2. it has a touring screen, which worked for the previous owner who is about 5"4, but I find I get a bit of turbulance straight into my helmet I'm 5"9. 3. This isn't major, but I find the bike spits back every now and again usually when blipping the throttle and the revs drop down to idle it will give what sounds like its spitting back into airbox. it only does it once then it seems to stop. Is this normal?
