Proline hp500 & gx270 FS

I have my pump up for sale. As im going to twin gx200&hp400’s to get the weight down.

2 seasons old but only done 20-30 hours tops.
Put a hop up kit in it but gone back to the original valve springs as compression made it too difficult to start. Still running the advanced timing key and main jet.
Will come with the kac compressor pulley.
Not the compressor

Looking $2800 ono
