Did about 3 hrs of trail riding today. Love this engine now It wasnt all that impressive on the street, but in the dirt is where it really shines. It is sooooooo strong down low, even from as low as 2500rpm, and pulls smoothly all the way through. The most impressive feature of this donk is it's ability to pull when overloaded. Where before it would just stall (generally followed my me and 426 sliding backwards down the hill) now it just keeps chugging along. Me being a novice at hillclimbs this helps get me out of sticky situations a lot Havent played with the MJ yet, but I think I have the needle about right, maybe a tad rich just to be on the safe side. Not too sure on the compression braking though Crawling down some steep loose hills the back was locking under compression braking which wasnt what I wanted. On the not so good side, it sounds like there is a woody woodpecker living somewhere in the bottom of my engine (he only pecks when he is hot) . I guess I had better investigate that tomorrow morning before I head out again. F%$@ I love this bike, even if I do spend more time working on it that I do riding it. Funny story about todays ride. Found this neat single tril through some rainforest. Tight, smmoth, no ruts. It seemed too good to be true. It was... it was a walking track ! Not sure who was more startled, me or the bushwalkers. I stopped to apologise and explain that I have NFI where I was and they were cool. Last thing we need is more people complaining about trailbikes.
