This engine only has about 6 hours on it, but I recently gave up on my aspirations to travel long distances over remote terrain on it, so I no longer see the point to keeping it trail worthy.
The engine came with a rough attempt at Phase II mods which I gingery tried to smooth over without adding to the loss of bottom end, but as much as I will defend its ability to be ridden in tight areas the fact is that it needs way too much clutching before attempting a jump to warp speed without notice. As much as I hate to admit it scares the bejesus out of me on anything but a long flat surface. I don’t know if it’s just the added traction, but it feels like it accelerates faster than my 300cc bike when it’s on the pipe.
So here goes. Below is what’s getting bolted on after the ports get another tweaking.
The Sprock head has a pump dome and that’s just fine with me, I don’t believe that 2 strokes like a lot of compression to start with. Thanks to off-Road Innovations for the head and Ricochet Off-Road for the dip in orange juice. More parts may end up there before this is over.
My manifold actually took the 38mm carb without a lot of fighting, but the boost bottle had to go, so a Sprock unit was picked up from Mrs. Mosh. I plan to use it with the stock cage, so it looks like some matching work and maybe even a little JB Weld will be needed.
The fly wheel was sent out to have 5 to 6 ounces lopped off. I’d promote the place that did it, but I’m not thrilled with the workmanship, so that ain’t happening.
The fuel Tee from SBDesigns here in the 3WW Store has been waiting to go on for a while now, as has the tether switch. The HD clutch springs are likely going to be needed at this point.
Also picked up a stock swing-arm from Manbearpig that will be lengthened, but how much is still to be determined.
You may have noticed some orange Yamaha decals in the photo. Still not sure about that. Input welcome.
