  1. Yeah its deff goona be expensive to maintain...I didnt know about all the mods when i bought it. The person i bought it from wasnt the one who had the mods done, he bought the bike and rode it twice and it was too much for him (was his first bike) and he has no contact info for the original owner. Also i dont have the original cams... :/ Im now thinking of running the cams, high comp piston, high performance double valve springs and putting Faction stailess steel valves in it but id like someone to verify that this combo isnt a ticking time bomb...I just wish i knew what the valves in it where or had ,more money to just replace the whole valve train.
  2. Iv got an 09 yz250f that i am re-valving. The motor has had TONS of work done to it! Port and polish, Webb cams, double sprung valves, High compression piston, hot rod crank etc... however I dont know who did the work or what kind of valves are in the bike. I know they are titanium. The head had a yoshimura sticker on the side but they can not identify the head and i pealed the sticker off and discovered an engraving of: CG T.R. Does anyone know who may have done this? there is also an engraving on the front of the head that is: 1908. I just want to know whats in the valve train so i know what valves to get to match the springs and such. I dont want to for out the cash to buy all new high performance valve train because im working on a college budget here. Any help is appreciated!!

  4. Iv got a 2009 yz250f that im going to fully rebuild the suspension on before this coming season. Im about 5'8"and and 155lbs intermediate racer, ride in mostly sand but a couple tracks are a mix of hard pack and clay. Im planning on buying the springs and valves from factory connection or rg3 and installing them myself since im a college student with a limited budget. What spring rates and valves should I be looking at? Any help is appreciated Thanks!
  5. No im lookuing at the full system.
  6. No the part number is the same for a 2011 but if you look at any other brand or even stock yz250f's the pipe fittings go from 06-09 and then a diff pipe for 10-11 but yoshi's rs-4 says 07-11 which is why im worried to order it
  7. Does anyone have a pic of a Yoshimura Rs4 pipe on an 09yz250f? Yoshi claims it will fit an 07-11 but any other brand pipe has a different pipe and part number for 06-09 and 10-11. I really want this Rs4 but even with Yoshi's wordim nervous to spend the money and not have it fit. Thanks
  8. Yeah i am prolly goona change the gearing but i think it needs ,more then that. Any more suggestions guys?
  9. No ill still try to get ahold of him. I know he's extremely knowledgeable and could prolly give me some suggestions but he's just so busy that its hard to get work done by him. But suggestions is what im looking for anyways
  10. Lol I took my rmz head to him a couple yrs ago for a valve job and after a month he hadn't touched it so I just picked it up and took it to iron dog instead
  11. Yeah its been rejetted properly. Not sure off hand what sizes are in it but ya that's been done
  12. hmmm never heard of em but ill do some research. any other suggestions? im open to mre then just pipes as well
  13. Anybody had much experieince with 2-bro's pipes? the m-7 cf pipe looks sikk and is really good priced for the full system but i havent heard much about them except on pit bikes.
  14. ya i found that but its for a 2010. idk if itd be similar for an 09?
  15. Iv got a 2009 yz250f with factory yoshimura motor mods done (port and polish etc..) and the bike has all the torq in the world!!!! However it falls a little flat on the mid-top range. Any suggestions on my best options? Im sponsored by loudmouth so ill have an intake coming pretty soon here. But what would the best pipe be? And any other possible mods to help me out? Thanks!
