  1. Old-man, I have only used the stock 742 and now, a D756. I absolutely HATED the 742. Switching to the 756 has been pure heaven. Z4
  2. Doesn't the 450X already use stainless steel valves? (unlike the 450R)
  3. Even stock, every 450x needs to be rejetted.
  4. My top 5, in no particular order: 1. ESP Suspension 2. Scotts Damper 3. JD Jetting w/recommended airbox mods 4. Twin Air PowerFlow 5. Replace stock D742 front tire with a D756
  5. I second that! It has allowed me to go quite a bit faster, with much better control. I love my new ESP suspension! .
  6. ALL 450x's come way too lean from the factory. Cold weather just makes it even worse. Properly jetted, your bike will last longer at idle before spewing. These four-strokes can get pretty hot when just idling, so try to keep it to a minimum. Even when properly jetted, I would still keep a watchful eye on idling time. Just my two cents.... JV
  7. I have the same one. Very easy to use.
  8. The D.I.D. chain that comes stock on the 450X is a REALLY good chain. Good luck finding something better. I've had my bike over a year and have yet to adjust the chain. It has the same slack as when it was new. The one that comes with the 450R is garbage. Z4
  9. It NEEDS to be rejetted, no matter where you are. Stock is WAY too lean for any conditions. Go ahead and get the JD kit. You will be very glad you did. Z4
  10. I'm going to give these settings a try next time out. Z4
  11. I just checked the yamaha and honda US websites: WR450F = 246.9 lbs CRF450X = 250 lbs For what it's worth...... Z4
  12. KTM 250XCF = KTM 250cc Cross-Country-Four (stroke)
  13. What happens to the stock Renthal crossbar pad? Does it then get trimmed, or not used at all? Z4
  14. Now I'm curious. What is the stock pilot size? Z4
  15. Thanks, I'll give them a call soon.
