Default 2.5 Sirio piston crank and sleeve sux?

Do any of you have this conversion,cause I was highly dissapointed with it...
I mean it did ok,and increased the power a little,but not what I was expecting...
The local hobbie shop guy said it would put out insane improvement ,but it didnt....
Do any of you have this same problem,and before any of you say check for leaks and fuel line cracks and so on...I have been in this hobbie fot some time now and I have already done all that,but still no great improvement,and yes Im running a tuned pipe...

Comments greatly needed? thanks

a new crank is needed for that too???? What problems are you having with it? Heat, reliability, overall performance?

I think he's just disappointed in the amount of power that the setup creates...I asked about this earlier and no one responded to me. I bought an OFNA/picco 21 for the maxx instead.

Just for the record,I did get the crank with it,but it still dissapointed me,and I was just wondering what others opinions are on the setup...

What Im ultimately getting at,is that Im thinking on going with the TEAM ORION Maxx .21,and Im hopeing for a much increased performance gain over the Sirio conversion...
The question is>....

What do yo guys think?
