Yes, the transfers, for all intents and purposes, are somewhat larger, but, not better than H2R attempts. The actual aiming angles into the bore are not as good as they should be, and there really isn't enough room to make them much better. Although volume helps here, aiming the mixture into the right places when the loop scavenging occurs, is paramount to getting a two stroke to be efficient in transfer operations. If the angles, and mixture paths are not advantageous, short circuiting will occur if the angles are too acute, which moves transfer mixture not to the correct place in the cylinder, but straight out the exhaust. This leans the fill to the rear of the loop, leaning the captured mixture out, no matter how the jetting is. In my files, I have a port angle study between the H2R and KR759 vs TZ 700/750, vastly different, even with the reeds on the Yamaha, transfer angles significantly different. Just "hoggin' them transfers out" makes more problems than helps. JP, if you would PM me with a real world email address, I will send you that page. |

The earlier KR cylinders have a bridged exhaust in addition to bridged inlet. I'll take a couple of pics tomorrow. |
