Well, since I wont be needing or buying another bike anytime soon, I think it would be wise to have an hour meter on my 06 YZ450 just to be sure the maintenance is done at the proper intervals. Ive seen some with tachometers but what benifit is that except for setting your idle (which I do buy ear and riding conditions). Are there any suggestions on this from people who actually have one on thier bike? Thanks as always for the info! And just a little extra thanks for this website and forum. I cant tell you how much I have benifited from everyone thru the last 4 years. I wont even guess how many mistakes I would have made reguarding the input from everyone here on TT!
