1146-33 is going to be less all around power that what your B10 was.

1143-7 will be close to the same power of your B10 with more top RPM power and possibly a little less bottom end than what you were running. You will most likely get a little worse fuel mileage with this as well.

Im getting a x10 next week would a jp3 work intill i get enough funds for the 2045 pipe also i heard the 2013 siro works well for this engine. Any info on performance would be cool.Im looking for a smooth engine that can rev to moon.

The JP3 will probably be ok to get ya started but your fuel mileage will not be very good. The 2013 isn't gona be the pipe you want if you want high revs... you probably want the 2045 or a 086 pipe of some sort. I have been running my X11 with the 2045 and it has been great. Not quite as much power as the B11 but still plenty.

OK Chris, thanks again for the help and expertise!!

Best regards

I took the restrictor out and ran it,I really think the problem was I was just running it to fat.I lean it out, still had good smoke and it ran good.I'll put one of the restrictors back in if I can't make 6 min. without it.The motor has got 1.5 gallons ran threw it since ceramic bearing and pinch so maybe it was still breaking in.Thanks for the help.

I ended up running the smallest restrictor i had and leaned it out.It had plenty of power for my driving skills.

DO THEY STILL MAKE RB 728 and a 928 motors or the inner parts my 929 looks pretty good needs resized who would be good at this job ??

Hey guys,

Anyone know how to get a hold of this item? Is it the same as the B11? Local hobby store can't get ahold of it, and AMAIN always on BO.

Thx,
Lucas

The B10 and B11 sleeve are not the same. The B11 has a smaller exhaust port than the B10 does. It will work and fit just fine, but it won't run exactly like it did with the B10 P/S/R.

Just wondering if I would be losing something with the B11 P/S/R? Is there a way I could machine the exhaust port to normal size?

You could have an engine modder change that exhaust port if you like. The smaller exhaust port makes the engine better on fuel with a little less power.

Can anyone suggest a starting setup, ie venturies, pipes fuel etc.....for oval on road. I blew my classico 10 last race, granted there was something wrong with the engine to start, I don't want to go through the same s#!% again. I kept it at 230 max temp.

I'm running 20% odonnels speed blend with extra caster oil.

Any advice would be great.

did the rod bushing go out ?

The rod didn't just go, it disapeared. After I opened it up I saw the sleeve locator pin had been broken, probably from manufacturing mistake. So the sleeve was off by a couple of mm and seized at the exaust port. All that being said I don't know if serprnt 966 is made for high speed oval. I was averaging 96 kph, the track was 500 m and I was pulling 7 second laps.
