At first, I installed the blue 'racing CDI':
https://www.amazon.com/Glixal-ATMT1-...5046976&sr=8-5
With that one, I did notice a little pickup with the stock pipe and baffle out on the muffler. The baffle is just a decibel reducer, sorta. But does add a few MPH when taken out - like 2.. but hey, more!
Now - without the catalytic converter and EGR / SAI, the fuel rate is MUCH more rich and all the exhaust gasses are exiting the pipe. The EGR / SAI crap pushes dirty air back through your intake. But, with the stock catted muffler I was on a 120 main jet - switched pipes and was waaaaaaaaaaaaaaay too rich. The orange CDI just fits better and matches the color so,
but between the orange and blue CDI's I can't tell a difference.
The exhaust pipe on this bike is kinda strange - very weird shape, and all one piece.. no middle pipe and doesn't bolt to the frame in the middle - just on the exhaust port engine side and the muffler... that's it!!
The stoneman exhaust and the Power Core exhausts won't fit this bike - I have a power core 2 full exhaust just lying around unused. Didn't feel like trying to bend it either.
It's not in the pics, but where the shift lever is engine side, the pipe was rubbing against it. I took the pipe off, saw where the lever was rubbing the pipe, took it out in the shop, placed a piece of wood under the opposite side of the shift lever marks, and beat the s#!* out of it with a hammer
Now there's PLENTY of room for the shift lever to move! Haha.. I think I can list that under 'custom build' when reselling - right?
The CDI also has an effect with the aftermarket plug coil too - big, big spark lol I am also running the NGK Iridium DRP8EiX-9 plug; stock is NGK D8EA, too! Didn't know that before buying. But does seem to be better than stock.
Thanks though, man! Though, I may have to keep up with tknj99 on the internal mods! I haven't performed any internal upgrades yet. I really want to try that 280cc big bore kit though - see what this thing can do with more powa!!
