Just completed a few changes and tidy-ups on my 2006 Bullet (6000 kms) The new additions are a good improvement and I am pleased with them.
Although I don't use it (my wife likes it) I had a new sprag clutch fitted to the electric start, I guess this is can be a bit of a problem with some of the electric starts.
New chain and Avon Road Rider tire fitted. Really good improvement for cornering, the stock tires don't quite do it for good cornering but seem fine for most other conditions. This is probably the widest tire that can be fitted.
New 18 tooth sprocket for highway speeds. I don't do much high speed driving but for road cruising this sprocket makes 60-65 mph quite easy when needed. I did think of using a 19 tooth but thought with 2 up at times it would work a bit hard at low speeds. I am only guessing on this.
New short exhaust for that "scaring chickens" sound.
Somehow during all of this my emission control stuff fell off.
