P5XLT vs. RB Fire 11, both stock?

Primarily for truggy, but could end up in a buggy.. Fire 11 with pipe for €15 more than the P5XLT, sans pipe.

thanks guys

sideshow bob- there are a few different methods in the break in bible bro , im sure u know what you're doing, you've been around like Kijana said , it will take a longer period for the break in process . remember this , if you lean the engine out and it doesn't gain any power, its not ready , keep its legs closed


herrsavage- youre silly
you want awesome bottom , decent top ?
or
no bottom and huge top ?

If the Fire supposedly has "no bottom", then why is it seen primarily as a truggy engine, and as too much for buggy?

New engine, only difference is the cooling head as i think. Compared the partsheets, and can not find out anything else.

What should the break in settings be on my novarossi 4btts? Also i am having trouble keeping it running during break in, it will idle on the box fine but i can only get it to about 1/4 throttle and then it dies same thing if i put it on the ground to do figure eights and what not. If anyone can help me that would be great! Thanks

So was this actually the engine that was used at Worlds?

I see they have a btt and btts Worlds edition. So which one was actually used at Worlds? Guessing the btts or something else?

Please inform me if this is something other than just pure marketing. Seems like I can get a standard btt or btts and have it be virtually the same engine and probably get it for a little cheaper.

What is this engine Nitro House was advertising, Nova Rossi, Beat .21-B4?

Also, a Nova Rossi Maxys Cinco BT .21 5 port? Are these engines made for these stores only?

Nova Rossi makes 2 engines for Mugenseiki both with Beat in the name.

Mugen Racing is proud to announce the “Beat Series” of engine produced by Novarossi. The combination of Novarossi and Mugen has created 2-.21 Off Road Racing Engines: the Beat Plus 21-B4 Tuned and the Beat B5. The Beat Plus 21-B4 Tuned is based off the Novarossi Plus 21-4 BTTA Tuned but with a different conrod and sleeve which creates a more linear power band, higher top speed all with the same great fuel mileage. It is finished off with the traditional Novarossi purple head with Beat graphics. The Beat B5 is the exact same engine as the Novarossi P5 but decked out with the Beat graphics on the head and crankcase.

Maxy makes fuel and mods engines. Apparently made a agreement with Nova Rossi for a engine.

Thanks Chris, have you seen the Maxys, engine? Needless to say, the price, not too bad, $279.99 BT .21-5 port, $339.99 BT .21-5 port, with ceramic bearings.

The new Worlds Edition is exactly the same engine as the previous BTT (front steel and rear ceramic bearing) - This BTT seems now to be discontinued and there is only a option with two steel bearings (the BTT/A).

Except the head engraving its the same engine, nothing new, even the same carburetor.
