Chainging the chain and sprockets is time consuming. Especially the first time. But the Jumbo tool is amazing. Just by changing pins and anvils, the tool breaks, tightens, and rivets. I could probably do the next one in an hour (not including putting on the rear wheel and alignment).
The new chain cured the light surging I had. The bike wasn't lean surging, it was the kinks in the old chain that were tightening and loosening. The bike is also quieter now. I could see the kinks in the chain, but the rear sprocket looked OK. The front sprocket, hidden under the fairing and slave cylinder, had some very curved teeth.
The Jumbo tool was over $100, but well worth it. It unscrews to a size smaller than the Honda tool kit (and probably more usefull). With my TWF discount, Speedwerks was the best price, had quick shipping and quickly followed up my e-mail questions. So there's no excuse for not fixing your chain or replacing it yourself next time.
