October 2, 200619 yr Sometime last year there was chat about a 230cc Kondo conversion for the RS200 engine. Did anyone manage to find a supplier? If not can anyone recommend an engineering shop to put a new liner in my existing 200 barrel?
October 2, 200619 yr You can, I think, get an oversize piston for the Seeley from Gordon Farley Motorcycles. Bloke called Tim knows the Honda engines well and will confirm. I think they come from a pump motor or such like. Liners can be done by Jet Bore or PJ, both in the Midlands and advertise in TMX. The 230 conversion is a bore and stroke job, not just a bore and they also had weights added to the crank. I think about 220 is max for just a bore. Ellastone Offroad often have RS200 motors from Japan with enlarged capacity so worth giving them a try for a complete motor. They also advertise in TMX. WES have recently had RTL / TLR pistons made. Don't know whether these would fit the Seeley motor but at 70mm diameter they would give a capacity of about 222cc on a Seeley crank. They're 4mm bigger than a standard Seeley so it may be stretching the liner a bit.
