here you go the pic is taken by the comp so it might not be to good .

its the stock carb that comes on the rb s5.

O.k this is correct. As you turn the screw inward (clockwise) it pushes against the throttle thus opening the gap even further. As you screw it outward (counter clockwise) it releases pressure against the carb. slide and closes the gap.

This is normal operation.

I have a Killer 10 combo with the 2045 pipe, what run times can I expect from this setup ??? I know its a open ended question, just looking for ball parks???

Hey guys
I just bought my first RB motor the B11 and cant wait to get it. I just have a question about the possible runtimes from the motor. i will be running and rb 2045 pipe in a mbx6 and just would like to know if with this pipe and motor i could make 10 mins with the right tune? any other tips for run in and stuff would also be handy.
Thanks in advance

I have never tried one of these pipes. If your looking for a good deal the Dynamite 053 and 086 pipes work pretty well on your engine.

With the right tune you will be able to do a 10 minute pit, BUT... You will have to give the engine a gallon+ to fully breakin before you start getting good fuel economy. One thing I have noticed with locals that also run RB's is that the Mugens drive train is not as smooth and free as some cars so that will hold back your mileage a little compared to cars like the Kyosho, Losi, Agama, and JQ.

Did you order the new combo that comes with the new 2087 pipe? That pipe will help you get better fuel mileage when compared to the 2045. If your going to try to use a JP pipe or something the chances of a 10 minute pit are not very good.

Also remember the heat gun is your friend. If you heat that thing up every time you start it up untill it no longer has any metal pinch it will last you a very long time.

Sorry man, that is an engine I have never used. I believe we have a team driver down south that is running the engine so hopefully he can chime in shortly and let you know what his run times have been with the engine.

That is only the case because they don't maintain the bearings the way they are supposed to. I have an MBX6 and lube the bearings after every other race day but i clean them out with WD40 after each race day through the holes in the hub carriers. I have timed my drive train after a quick rev of the motor and shut it off and it literally spins for 45+sec with the stock bearings.

But anyway, I have the Shark 10 which is practically the B11, with the 2045 pipe and can do 11:30 pit stops.

No they didnt have the new combo on amain so i just bought the motor as i already have a 2045 pipe. yes i will not attempt a 10 min race tune till break in is fully complete and motor has lost mechanical pinch. What should i heat it up to before starting and what temps should i run it at for the first few tanks?
thanks

Try to heat it up to 200 before starting it. Once you have it going even for the first few tanks try to always keep the temp up over 200 degrees. After the initial 5 or 6 tanks you may notice the temps getting up around 240 ish even when kind of rich... That is fine!! If it starts creeping up to 250+ you will want to richen it up a bit.
