Took it back to what the instructions say, and, its not perfect yet, but its getting very close now.

Either way.

Why is there absolutely no information on this engine, not even by RB themselves?

BD there are lots of us that run these engines with no probs, if you need a hand just approach us at the track and we can assist. Be patient with it they are very tight at new. a good tune and full power wont come till they loosen up

RB T9 vs RB R3
 
hi, can i use R3 cooling head on T9, will it run hotter :sweat:(because they are different in size) thanks!

i think so because they claim that the new design of the cooling head reduces the temp. of the engine

Unfortunately i don't get to sydney racing.

Power was never an issue, nor was tightness. Even after a very slow 2ltr of fuel, it would start easy, but it just wouldn't run very long.

Since finding the problem, its been running well. The fault was with RB, no fault of ours. We took for granted that the needle settings were right from factory (like every engine we have had anything to deal with)

does anyon eknow why RB used a AAC sleeve in the alpha motor instead of a ABC? ive heard alot of bad stuff about AAC

AAC
 
The AAC engines are fast . I have a zenon and love it. I never start it without heating it first. I have put about 3 gallons on mine and still can't turn it over without heating it first. With these engines you cannot ever run them lean or you will ruin them.

how do you heat at track? they have power there, also do you have to heat in summer when its like 90 plus outside? ive been wanting to try one out, but the heating deal has me stuck,unless i can find a way to provide portable heat..lol..these guys are light as well, surely you have to adjust suspension to accomandate

when I run one, I use a small torch to get it to about 150 to 160 degree's

before I start it, I alway's pre heat it, let fully warm up before tuning

Heat
 
Yes I race at a great track that has power outlets. They had the 1/8th worlds there in 2003. I heat mine with a 1600 watt hair dryer. It gets it to 170 degrees.

r3
 
Hi,


Anyone tried using the "maxpower turbo tuned pipe 2602" on the RB R3 ? Is there a big difference in using it versu the 2604? coz right now its the only avlbl pipe I have.

thanks.
