12ps Barrel
Posted: Sat May 23, 2020 3:46 pm
Hi, looking at these PX200 barrels advertised as 12ps (mostly from German shops), are they really 2.5-3hp over a standard barrel ! Has anyone used one and had it dynoed ?

Possibly a sweeping statement Gaz, I bought a pattern LML 150 5 port reedvalve cylinder a few years ago from an Indian dealer, it cost £24.99 for the barrel and piston (no head) and £24.99 shipping. It arrived in under a week and the quality was amazing, ports all nicely finished and far better than either of the GT barrels I hgave had. Slight concerns about the quality of the unknoiwn brand piston have so far proved unfounded although not many miles logged up yet. Some of the other stuff I had to buy for it was shite thoughgaz_powell wrote: ↑Sat May 23, 2020 6:59 pm.......I think the difference is over the Indian shite that you see for 60 quid with badly cast ports etc
Was only referring to the Indian/far easy produced P2 kits I have had through my hands, to get them working properly they needed loads of works on the ports, the alloy ones that appeared had the liners off true, the bore clearance was terrible, piston ports were undersized.coaster wrote: ↑Sun May 24, 2020 11:56 amPossibly a sweeping statement Gaz, I bought a pattern LML 150 5 port reedvalve cylinder a few years ago from an Indian dealer, it cost £24.99 for the barrel and piston (no head) and £24.99 shipping.
