I had a YZ 400 1979 F model, it was more of a bike than I could handle but at 18 I thought I could handle anything, fast! A friend and were out trail riding in the forest trying to outdo each other, like you do. He went past on the back wheel up a long loose metal road so not to be outdone I went past him on the back wheel only I was in fourth now, you guessed it, over I went skidding up the road on my arse stones flying everywhere watching my 400 go end over end. Finally we all ended up together in a heap but the 400 was still at half throttle with its handle bar in the ground, middle of the road, still in fourth going round and round in circles throwing stones at us. Kill switch had gone, what to do??? You try locking your throttle on half in fourth and let your bike go and see what happens, it's like a possessed monster with a mind of it's own, what to do?
So as it came round again I lept in on it thinking I I'll just pick it up, what was I thinking, all it did was wheel stand off leaving me on the ground with stones still getting thrown at me!! This time it when over the edge down a bank through the scrub mostly blackberry and gorse, now what to do??? If you have ever heard an air cooled 400 cc bike free revving at
? revs it's not nice and all I wanted to do was shut it down before it exploded. So now we are standing on the side of the road looking down into the scrub, smoke rising, and an unholy noise coming up. I had no choice, It had lots of fuel on board, into the mess I went still not sure what to do I think a little shock had set in by this time thankfully it was up against a tree so as I picked the bike up this time I was able to run it into the tree and stall it. I must say it was all I could do to hold it there until it quit! Now finally the noise had stopped and in the silence all I could hear was my friend laughing, funniest thing he had ever seen. After I stopped shaking I had to laugh also, you know I had had problems with the throttle sticking some weeks earlier, something you probably want to sort out on a 400 cc twostroke sooner rather than like me, later.
