I get the feeling that most on here who suggest a converted open class MX bike is superior to a smaller machine for tight woods riding, are play bike riders who never take part in serious competition?

Nothing wrong at all with riding an uncompetitive bike for playing, but a bit silly to claim they are likely to better smaller much easier bikes in serious competition.

My views on this are also held by someone I know pretty well who is the manager of one of the main WEC teams, who is still a very good rider himself.

i don't see anywhere in this thread where anyone has intimated that the big bores are superior to a small two stroke, aside frm one guy mentioning that he didn't find it any easier on his kdx200. one guy. otherwise, the ONLY person setting up this straw man argument is you. the thread is about making a particular and in some areas notorious big bore two stroke motocross bike into a usable trail machine. pay attention, and quit trying to start fights just for the sake of it.

(and i willingly admit that i am way faster in the woods on my ktm200 or gasgas300 than i will ever be on my rxv550. now seriously, stop trolling, dude...)

Well, I am a fairly decent A enduro rider. Ive raced everything from a 125 to a 650 4t and have been racing for close to 30 years so I think I have a bit of experience. Most of my race bikes have been 250 mx bikes converted for offroad. During my hayday that was the size bike that worked best for me. At 45 years of age I am still able to run fairly well against the fast guys in my class and even pull a win or 2 out of my hat. Now days, I just dont feel like shifting and clutching all day to go fast and prefer riding the 500 over my 250, which I still have. It saves me energy and lets me enjoy the ride more. Its fairly stock engine wise and is not the mythical, uncontrollable fire breathing dragon that they are made out to be. I dont work on it as much also. I used to buy bikes that I thought would make the most effective race machine but were not necessarily the most fun to ride all day long now I ride what I feel is the best bike I have ever had, even though I had to build it.

To the original poster, Im sure that quite a few parts from a IT490/465 will bolt on to your YZ to make it a great offroader. The wr trans and ignition can help tame it down and make it a more versatile offroader.

I don't know where you ride now Hawaiian, but the piece was written by me after having grown up in the South Jersey Pine Barrons, on a stock CR480 at 17 yrs old. You hit it right on the nose earlier when you said the key is throttle control. This I learned early on the 480.

Thanks mudmantra. The Famous Super Hunky himself contacted me and published my article in `04.

Ahhh..very well said. Sounds like my street legal, enduroized CR500.

Superior at throwing large rocks at 200cc riders.

Superior? Yes...by far.

Don't fret mudmantra...all the good mods you'll need to make your 490 a kickass woods bike have been posted.

Twin-Shocker is just tired of getting roosted by big bores. One can only take so much sandblasting!

i have ridden both small and large bore 2t in competition. my riding style suits the 'wring it's neck' style the small bores offer. they each have their issues - i have to push a 200 very hard. the 500 the exact opposite. i like to be on the pipe and screaming - which means the bike has to be really close to optimal jetting and timing.... i certainly can be faster on the big bore, or the small bore - it really depends on how you ride it, the conditions, etc. there is no doubt the big bores last way longer. both take skill and brains to ride consistently fast.... the lightweight of the small bore is a definite trade off for the easy to come by power of the big bore...on a small bore, i twist the throttle to it's stops every time. on a big bore almost never, why would you when you can just shift up, and stay in the same rev range/throttle position.. when the going gets real slow/sloppy, the big bore wins, you don't need to think about being in the power, it's always in the power.. it may not be as snappy, but it's exiting just as fast as the smaller bores, just doesn't sound like it is...throttle and clutch is everything on both bike sizes..... and whoever brakes last and makes the fewest mistakes wins anyways

Gore makes a Boyesen Port in his 465 cylinder but I don't see the gain being worth the effort. But he has been doing this longer than I.

Correct the head for compression,MSV and clearance again keeping in mind usage. Keep the stock carb 'cause a 38MM is small for a 465/490 and suits low-mid range power. If you want to make the most of the new port timing a couple pipe mods and tuning ignition timing would finish the job.

All rather elementary if you know anything about smokers. Perhaps turning off the computer,purchasing a motorcycle and riding it would lead you down the path of modifying for performance instead of just buying new. Then again maybe not. Too many good motorcycles rot behind barns and garages because of that attitude.

What say you now?

I had an 82 YZ 490 that I originally purchased to race MX. Then entered a few offroad events with it and thought the bike worked better in the woods than on the MX track.

If you can find a DG pipe for the bike it makes a huge difference over the stock pipe. Really smoothes out the power band . With the DG pipe you could pretty much ride the bike in 3rd and 4th gear.
