The buku clutch can be adjusted with screws in the flyweel. How does it work ?
Must all three screws adjusted equal or different if i do it ?
Are the ABK shoes the same as komposite ?

It's the same I.D. as the Factory Mugen. The offset of gears on the ofna bell are not quite as long as the factory Mugen bell. This makes the spur gear ride closer to the end of the clutch bell putting more stress on the front clutch bell bearing. I have used ofna's with success but they will eat bearings faster. I prefer the new vented mugen bell for 3-4 dollars more.

It seems that carbon fiber towers allow an easier driving.
Do you guys know cf towers part numbers?
Thx.

FWIW - Here are your final gear ratios with and without under-drive. Going to a 48T center gear is near identical to changing to F&R under-drive
Mugen Gearing
46/13 Clutch + 44/13 Diff = 6.92 : 1
46/13 Clutch + 42/12 Diff = 7.04 : 1
46/12 Clutch + 44/13 Diff = 7.21 : 1
48/13 Clutch + 44/13 Diff = 7.07 : 1
Mugen Gearing
46/13 Clutch + 44/13 Diff = 6.92 : 1
46/13 Clutch + 42/12 Diff = 7.04 : 1
46/12 Clutch + 44/13 Diff = 7.21 : 1
48/13 Clutch + 44/13 Diff = 7.07 : 1

Raising the spur tooth count does not have the same effect as raising a front or rear diff ring gear tooth count. Under driving the rear makes it feel like the front of the car is pulling the car around in my opinion. A 48t simply raises top speed and removes some low end

Sorry yes I was thinking pinion/bell when I was typing but yes you are right but my point was more that raising the center spur is not the same as changing just the rear diff pinion and ring gears. But yes if you changed both the front and rear its defeating the purpose.

Has anyone noticed the shock shaft gets significantly more friction, as you tighten up the cartridge? I understand as you push the orings closer together it should get more pinched, but there seems to be extreme amounts of friction when the cartridge is snug. Even when you back off the cartridge a half a turn, it doesn't seem to help much.
Are you guys using different orings? Are you backing off the cartridge more than a turn (but then you run the risk of unscrewing itself)?
Thanks!

why do the diffs feel like the big gear is rubbing on the case..shim…no shim…Ive dremeled the case out a lil where the gear passes..its on the correct side as well,,,,did it on my 7 and now I'm putting together my new R and problem still exists,,front and rear

It seems a bit odd that you are the only one to be having this problem on your mbx7 kits, where on the crown gear is it rubbing the diff housing.
Can you post a pic to show us?

Can I ask what people are doing to fix the sticking fuel clunk issues?
The fuel tubing in mine seems very short and will not let the clunk travel all the way to the top of the tank when upside down. I replaced with tubing about 4-5mm longer, and trimmed the side of the baffles to let it move easier, but now the clunk will hit the stepped wall on the back of the tank.
I'm really surprised there seems to be so much afterthought in the design of this tank
