Thats sucks, thats what my setup is. Did they let you run?? What pipe did you run, or what pipe is everyone running besides the 2045.

I put on a JP3, but it was legal in the truggy class:confused:, I just posted that because we had problems in the past with the stinger size on our buggies. It would suck to drive a several hours to race and then not have a legal pipe. We are looking into a bushing or someway to crimp the end of the stinger this year. As long as their gauge doesnt fit in the end its legal, thats what we where told.

RB ENGINE
 
I just got an S3 and I really love it.I am new too the nitro scene.How many gallons before it's junk?

castirontom 04-12-2009 07:03 PM

I have a S3 and gots to say it is a great engine its on a o53 pipe and i keep her around 230 on 30 percent o'donnels and man she screems. I wanted to do a os v spec (blue head) but this motor runs with them all day long and it gets better fuel economy. "Very Happy" to own it.

Does anyone know if i can put the crank , rod piston & sleeve from a s5 in my c6 ? The reason i ask is my c6 needs crank & rod but a guy at the track will make me a deal on the s5 parts so it would be much cheaper to fix. i know it won't have as much power but it would just be a back up engine. thanks

You can't use the S5 crank in the C6, the S5 crank is 13mm, the C6 is 14mm, this is based on main bearing inside diameter. The rods are all the same, on all the RB .21 engines.

Depending on your track size, the 053 will give you lots of bottom end, and will top out real fast, might be okay for a small track, the 086 pipe would be a better choice all the way around, IMO.

Got a few questions about RB ws7ll

- do i need to remove the standard plug shim? bec i find that if i use the plug with the shim, the bottom of the plug cannot sit nicely into the button.

- is there people using 16% for off-road engine? how many shim do i need to shim for this engine if im running 16% and 25%?

Thanks! As this is my first time dealing with off-road engine.

If you're talking about the glowplug shim then you leave that in. If it isn't sitting right check that you don't accidentally have two shims there, then check your threads out.

As far as nitro if you're running 25 percent and lower you can run the head/button shims stock at 0.3mm. If your engine has 0.4mm (from the last owner) it would be set up for 30 percent and you could remove 0.1mm of shims to run the lesser nitro fuels that you want to use.
