Guys, what do you think is wrong my Spec III.

 

#1. Shifting from 1st to 2nd gear and then to 3rd gear at 2,000 rpm is smooth.

It shifts so smooth and almost noiseless at 2,000 rpm; I have no problem at all.

 

But if I shift from 1st to 2nd and then to 3rd gear at 2,500 to 3,000 rpm and higher rpms I hear a very loud “thuck” sound.

The “thuck” sound is loudest when I am shifting from 1st to 2nd gear.

If I shift from 1st to 2nd gear at higher rpm say 4,500 rpm it won’t even engage to 2nd gear, it will just stay at neutral.

If I force to go to 2nd gear at this stage I will hear crackling sound as if I am not fully pressing the clutch.

But I am pressing the clutch lever at 100%, so I wait until my rpm goes down to 2,500 rpm then I shift to 2nd gear.

 

Shifting from 2nd to 3rd gear there is also a “thuck” sound at 3,000 rpm and higher rpms, but not as loud as compared to shifting from 1st to 2nd gear on the same high rpms.

 

Shifting from 3rd to 4th then to 5ht and then to 6th gear there is “NO PROBLEM” at all rpms even at 5,000 or 6,000 rpm it is very smooth shifting and almost no sound.

 

#2. On idle at neutral I can hear a sound somehow coming from inside the right side of engine where the clutch cable is.

When I press the clutch levers slowly from 50% to pressing it at 100% the noise slowly disappears.

But when I release the clutch levers the noise is there again.

It’s like a tiny a tiny crackling sound.

 

 

Any ideas on the problem of Spec III?

Bro, you need to pull your clutch and shift simultaneously. Try snatchin the clutch lever when shiftin gear. Its the loadin of the gearbox that causes the sound. The clutch, shiftin gear and close throttle must be done simultaneously. If done correctly, you'll have a smooth gear change, gradual increase in speed and power without the jerking forward and backward motion.

I will try to better my gearing technique.

 

Maybe you're right.
