My GPI was playing up, so after reading on here about chain tension & gear lever position being parallel with Slave lever, I set about the bike...... Bike now seems to show every gear position except neutral! It says 1 in neutral, displays 1 when 1st selected, then flashes green as I select 2nd & vice versa. I can ( just) make it select neutral on the way down from 2-1, it will be in neutral (no drive) but the gear lever is not in neutral-it's like it's hovering about where it should be. What's people's thoughts, GPI/neutral sensor or something else?
There's another thread on this, which I've just replied to (not that it will do you any good). I've been touring with mine for a week with his problem.
