Currently running:

 

Mains: 310

Pilot: 25

Needle Clip: Stock Position

 

Toomey T5s

K&N Pods w/ Outerwears (Airbox Delete)

TORS Removed

 

Bog: @ Idle to 3/8 throttle

 

Once it hits powerband, it takes off.

 

I think the 27.5 pilots will fix the initial problem.

 

But after that, I made a few passes up and down my road, and it started bogging more and more within the powerband range.

(After the powerband seemed fine, it was just the low end. But then the powerband started having a slight bog.)

 

I don't think I have any air leaks, but I will tighten things up, and look.

Stick that 27.5 pilot in. If your losing power the more you ride it that sounds like its overheating. Either your way lean on the main or your detenating. Is shee pinging at all? If not jump up on the main, maybe a 330-350

I haven't done anything to raise the compression, so I'm going to say negative on the detonating.

 

My "riding" wasn't long at all...a few pulls up and down the street.

 

Maybe it is overheating. :confused:

Don't go off my sig.

 

That's what it will be when I finish...I'm mid installation right now.

 

The head is not on, just the Toomeys, K&N, ported cages w/ petals and TORS Removal so far.

 

When I do put the head on, the timing will be advanced (+4 roughly) to keep me from detonating.

 

Edit--

 

I'm going to aim to install the pilots, and check out the impeller.

 

The plastic one may be trashed... (going to billet)

for sure you need to stick that 27.5 pilot in. try 320-330 mains too. also, you said "When I do put the head on, the timing will be advanced (+4 roughly) to keep me from detonating." you have it backwards...increasing the timing with higher compression, would double the chance of detonation. 21cc domes should still be fine on 93 octane, but if you increase the timing to +4, than you will need a blend of race gas and 93, to keep from detonating.
