Gear change mods

since buying the CBR I have never been happy with the gear change same as most people (it had 700 miles on ), I have done the shaft support, I have also put bearings in the gear lever, this has helped but has always seemed hard work to upshift and leads to false neutrals at times.
So taking a closer look, the gearbox gear lever spring pressure is very high, this means when you change gear you have to put a lot of effort in just to overcome the gearbox spring pressure.
I thought I would try to reduce the upshift spring pressure with a counter spring to see what it was like.
It has completely transformed the gearchange from one of making sure you have your foot in the right place and giving it a good heave to just changing up with your foot in any position and it being what I would class as normal where you just do not think about it
It now has about half the original spring load for upshift, it increases downshift pressure but I could not tell
I used to have sore toes from the pressure after a long windy run
I have also moved the gear link slightly a while ago so you don't have to move the gear lever as far, that is why that is modified
the pic I have put on is what I did for testing and now I know how good it is I will do something more discreet

 

Love how you can adjust the tension of the spring with a plastic zip tie

 

first rule of engineering, make it simple

 

Looks a bit heath robinson to me.the shaft support is a must.not sure why Honda hasnt fitted this anyway! My next mod will be R&G rear sets.also looking at the pic i see there isnt a QS fitted. These mods are not cheap but seeing you have the sp i would be chucking money at it if it was mine!

 

I don't use the bike loads it is just a summer toy, as you said QS aren't cheap so can not justify, The mod I have done was just to see how much it changed it, I didn't want to put loads of work in to find it did not work.

 

Fair play hope the spring mod works for you

 

Have you ever tried race shift @Jez ? First thing I tried when I bought rear sets and have never looked back.

 

Just checked race shift out. They do look good and are around the same price as R&G.thanks for the info.

 

Confusion here mate....I meant "Race Pattern" I.e. 1 up 5 down. Not as a brand of rearsets.

 

Aren't you adding a constant upward pressure? Is that a good idea?

 

Agree it’s a concern for long term use.
Technique for smoother clutchless up shifts is to preload the shift lever just before rolling off throttle and knocking it up a gear. If you’re riding around with the gearbox permanently in that state what’s going to happen?
Genuine question as I don’t know the answer but instinctively I feel it can’t be a good thing.

 

the gear lever has a lot of spring tension I have just reduced it, the gear lever still returns to centre with plenty of force,
the race shift pattern would probably just move the problem to going down the gears,
the reduced pressure just makes it so much easier to change and more positive
