eugheugh Posted September 7, 2012 Report Share Posted September 7, 2012 Just bought what appears to be a Gasser 125/160 water cooled barrel that looks like its been sleeved down to 80cc, that is, it's got a steel liner and a piston measuring 50mm across and a single dikes ring. Has anyone reading this heard of this conversion ? Quote Link to comment Share on other sites More sharing options...
lowbrow Posted September 8, 2012 Report Share Posted September 8, 2012 Must date back to the 1990's when if memory serves me correctly there was an ACU schoolboy class capacity limit of 100cc. Quote Link to comment Share on other sites More sharing options...
eugheugh Posted September 22, 2012 Author Report Share Posted September 22, 2012 Thanks lowbrow. For anyone mystified by this posting I can explain. I have been after a 160cc JTR barrel and head for some time and came across this modified barrel on eBay listed as having been modified with a steel liner-presumably because the original plated surface had worn. I have Identified the piston supplied as Yamaha YZ100 so whether this was a known modification or a one-off is unsure. It would be interesting to see if it actually works okay as a trials engine!!. Ports in barrel line up perfectly with the steel liner so whoever did the mod knew what they were doing!. I'm looking for a reed valve block and inlet stub if anyone can help?.
