Give him a chance, I can only imagine the work that is involved being the sole importer of RB engines to the states.
My comments were by no means an attack on brain.Thats who i got my usa spec from very nice guy and i got my engine lighting fast.I just dont think they release enough of product.There downfalls is by no meens brians fault.Just would like to get these more on a whime thats all.If something breaks most people buy what they can get fast in a pinch.Me ill get these motors even if i need to get them shipped from france LOL my c6 lasted 8 gal before i rebuilt it and another 2 before i sold it with my old buggy.Worth while

Thats not what I was trying to say my friend. I am just trying to let everybody know they just came in and in time they should be more readily available. I myself am a big fan and pleaded with my boss to get RB's in. I now push them on and off the track. It's hard and expensive to stock all the parts and engines so we are going to try to keep maybe one or two of the lower cost engines on hand. You are definetly seeing more RB's than before.

I tried to emial Rb but I got a failure notice...I was wondering what the difference was between the Hobby 9 and the Rally 9? The Rally 9 is turbo, for buggy, and is a "competation" engine. The Hobby 9 is standard, for buggy, and considered a sport engine-yet the Rally 9 is $5 cheaper. Why is this?

If they are the stock shims you should be good to go. The stock shims are .01 and .02 for a total of .03. .03 is good up to 25% nitro.

Thanks it has an O'donell head on it and when I took apart I didn't remember it having the 2 shims I put the head on it about 4 years ago . I was going to use a dynamite platinum .28 xp but it is too nuts so I'm going back to old reliable . It's going to be RB or nothing for me never had a prob with any of my RB's I don't know what the hell I was thinking .

I did a confirmed 8 minute pitstop today on my "Hobby 9" on a lot larger high speed track. I was able to run a RB#6 plug for the first time with some luck, I usually run McCoy #59 in my non-turbo RB' with 25% nitro. She is really starting to wake up after about a gallon thru her. The engine is more than enough for a buggy, for me anyway. I think I need to get a
"Junior 9" 3 port and relearn how to drive a 1/8th buggy.

what happened with the S line of rb engines?(s3, s5 etc) I assume they have been discontinued and replaced with the 9 series?

Yes, they have been replaced with the junior (S3) and hobby (S5). Basically the same except for the lighter cooling heads and aluminum orange carb pinch bolt assembly.

Default Help with C5

Stock the engine should have two shims;

1) 0.2mm
1) 0.1mm

that gets you a total of 0.3, you need one more 0.1 for 30 percent(0.4mm). You could also use two 0.2mm shims if you wanted, to only have to bother with a total of 2 shims.

EDIT: if you want to run 20 percent, use 0.3mm in shims total (probably the two the engine came with....although i'd still check)
if you want to run 30 percent, use 0.4mm in shims total
A buddy let me borrow his C5 that has just been pinched and had new bearings installed. I'm running a 053 pipe. I'm new to RB Motors, noticed that the new lineup of engines are way different than what my buddy lent me. I was wondering what a basic starting point for tuning would be and what would be a good engine to purchase for a small to medium track?

Im running a ofna 086 on my s5 and I love it. I ran it in my truggy this past weekend and I had spectators coming up to me asking what I was running. Not only does it have a pissed off sound, it has a ton of bottom, which I really wasnt looking for, I can break the rear loose on demand. I ordered another pipe, the dynamite 086 to try on a new motor, the reason I like the dynamite is b/c they come hard coated.
