Sudden drop in rate of fire...how come?

[Jagd]

Hi guys,

So I have the following problem with my CYMA AK 105:

I had a pretty awesome rate of fire with it especially with a 9,6V with my modify S90 spring.

I just changed the spring for a S100 one and put a new hop-up set (which apparently is the one with the best seal; the Element (red) one.)

I only cleaned up the interior, and regrease, did not touch the shimming that I did previously (everything was fine so there was no reason for me to do that.)

After changing the spring, I test fired it...

I notice an amazing drop in rate of fire. Even with a 9.6V it was very sluggish. And only an increase in about around 15 FPS. In Semi, the gun semi lock alot, I had to switch to full auto quite alot to unlock it.

So I am wondering is it because I have a really crappy motor? Because I changed everything on the gun except that. But it was working fine with a S90 I can't imagine that for switching only to an S100 spring the motor could not take it anymore..And also I am shooting at about 360 FPS with an S100. With a tightbore 455 and supposedly a real good hop-up chamber, I was expecting to shoot around 375 FPS...

Anyway if you have any input, it will be appreciated

It could very well slow down and even stop because of the spring increase. Try a larger battery, or fully charging your current one.

Well I am recharging my 9.6V atm, so will see. Hopefully it is only that

what's the amperage on your battery? if it's too low the spring might be too much.

It is a 9.6V 1500 Mh.

Problem solved guys, it was my battery, it was a brand new one, I had heard that they were full charge when bought new, apparently that was really not the case. So fullly charge I have the exact same rate of fire that I had before with my S90 spring (my other 9,6 is in my MP5K) and I even got an increase of 10 FPS. At least one problem solved!
