Who product motocross increased cylinders?

[Danthon]

Hi,
I wish change the cylinder of my Honda 125 motocross with a increased displacement one, if exist it.
I know that Athena products it for Yamaha, with 150cc displacement but don't products for Honda 125 (while it products for CRF 250...).
Do you know who products it?
Are they very reliable?
How much cost they? How originals?
Thank you

the 134 and 139 are 450 form eric the 144 is like 485 or so I am actually tring to get one together money is an issue but eric does the best work because he is the one who does all of it and his prices are second to none.

I have a Eric Gorr cylinder on my 500 and really like his work. But in a nature of competition here's an other option:

I have rode a 134 YZ that RPM did and it was sweet :cool:

My bad...

I did some homework and it looks like Rick sold out and the new guy is charging way to much. Call Eric Gorr...
