    Stuck Gear selector

    Hello people,

    I have a Honda CBF1000 from 2006 (bought it a year ago) and I experience some problems when shifting on the motorcycle.
    The bike has 69000km on it and had an oil change 7000km ago.

    One day to another my gear selector stays in the position I push it to and doesn't return back to its original position. It also needed quite a bit of force to push it into gear.
    After experiencing this I immediately went to the garage to have a look at it.

    So the issue was that my bike had consumed 1,5 liter oil in 7000km of riding. This meant that the mechanical part of the gearbox did not have enough lubrication.
    After he refilled the oil to its normal level the gear selector still won't return to its normal position after shifting. Altough the shifting does go smoother now I'm concerned that I might have get my gearbox revised.

    Does anybody hear have a similar experience or any tips on what I should do? :003:

    What you need to do is have a competent mechanic look at it.

    First thing I'd check would be the five pivot points between the gear lever and gear shift arm/spindle are all moving freely. However, from your description I'd suspect a damaged or failing spindle return spring but other parts could also be damaged. The gear linkage cover will need to come off so that a competent mechanic who knows what they're looking at can inspect and assess the other gear linkage components including the shift spindle bearing, shift fork, shift drum etc.

    Surprised the mechanic you took it to did not advise that much.

    Hi I have exactly the same bike, 2006 mk1 (just without the problem), what struck me apart from the obvious issue was your comment about oil consumption, all bikes are different for sure but your figure for oil consumption seems very high, 7000km is just over 4000 miles, which is when i change mine, but mine has never even needed topping up between changes in 8 years. Did you change the oil yourself? are you confident that the oil was filled correctly at the change? As a guide, mine takes just over 3 litres as i do the filter every time.
    Let us know how you get on.

    No actually he did. He checked all of the pivot points and even disassembled the top cover. Next to this he cleaned and lubricated the bearing on the top were the gear selecter shaft goes deeper into the gearbox. The spring was also in good condition and operated as it should. That's why I'm actually curious if somebody could explain what part inside of the gearbox is making my shift lever not return to its original position...

    I left my bike at the mechanic to change the oils and filters in the bike. My bad was that I did not check in 7000 kilometers how much oil there was left in the bike. As I didn't expect it to be lower by 1.5 liters of oil...
    As for the bike itself it doesn't smell like burning oil not in low or high rpm's. I even put it on the Dyno and it made more power than shown on the spec sheet. 105HP on the back wheel and 103Nm. I'm worried that the current issue is inside of my gearbox.
