Firco, I guess that you owned one of the production YZ400f models and not one of these YZM400F versions that were strictly Factory use?
Bill, I don't think that the accelerated maintainance costs hurt the ones who knew HOW to work on their bikes, but I laughed at all of the fuss over broken kick starter levers because the 2-smoker riders thought they could fan the starter like a 125 2-smoke! If you really look at the overall costs of racing from fuel costs to motor homes for transport and enclosed trailers and the cost of gear and parts in general, this is reason for the slowdown in racing. Heck for top level tires you can pay $200 for a pair and wear them out in practice and a race weekend if you run more than one class. I remember almost 20 years ago there was an article in Dirt Bike where it documented the cost of a father/family to keep their kid racing in Southern California. Understand that the racing was so concentrated that a kid could run 5-7 times a week, including Night Races after dad got off of work. And add in the cost for "practice" nights with track fees!
The magazine totalled up the entry fees, the fuel costs, tires, riding gear, wear and tear on the bike and came up with a figure of over $1000/week!!!! Tell me about costs? That was about 20 years ago and gas and tires and EVERYTHING was less expensive! And gentlemen, this was for a CR125 2-smoker!!!
When is the last time that you guys priced out a factory Maico or KTM 2-smoke piston? Those Euro parts are kickers when you open your wallet! How much does it cost to have a Professional do your suspension these days? How about some trick parts? Handlebars $50-90? Remember when we could buy Chrome-moly bars for $19.95? Stupid Graphics kits for $50-100 and more? Remember Paint and aftermarket stickers? I don't think that the 4-strokers drove up those costs, I think that the market did! New Honda CRF250R engine on EBay for $3500, new KTM 250 for $3300? Used to be able to buy a complete Thumper engine from Honda for less than $1000 in the crate!
Yea, times have changed and they are damned more expensive than when we started riding regardless is you are riding a Smoker or a Stroker!!
Still like the YZM400F Yamaha. It was the answer to the Husaberg and about damned time that the Japanese came around to get it right!
