  1. Hey all, I need some concrete specs on the '08 ktm 250xc. The manual and all the online specs vary wildly. Anywhere from 227 lbs dry weight to 215lbs. And 37.5 in seat height to 36.4 in. Manual says 215lbs and 36.4in height. However this is lighter and shorter than most other years of xc250's. This makes a difference in my next decision, because I am short in stature (30 in inseam) and I want to stay with a light bike. I currently have a yz125 and love it. I race hare scrambles in the rockies (even two endure-crosses) and moto . It can beat me up in some tech offroad sections but is serious fun in single track! Love to scream it and hop/skip it around. Its super fun, and really fits my riding style. I run tubeless and have it slightly geared down. Suspension is stock. And its perfect for the mx I race. I'm 165 lbs before gear. I would just stay with my yz, and maybe have the suspension softened in the first part of the stroke, to help with the tech sections. But I can't help but think about getting a shorter seat height and slightly softer (initially) suspension. The seat height really helps for offroad. My yz is 39in tall. I shaved the seat about 1/2 in but I still cant touch on both sides. And just the tip of my boot on the side that does. For mx it doesn't matter but offroad I have been missing it. I really don't want to go with something too much heavier either. The ktm 200xc would be ideal but they rarely sell in my area and they are ridiculous prices when they do. Even for early 2000 models. So if the '08 250 is actually 215lbs dry and has a shorter seat height....that might be the ticket. Even though I can get buy on big hill climbs slipping the clutch, it would be nice to have more low end. And I could race the more tech cross country races in the series that I have skipped. I really don't want to sacrifice my mx suspension too much though. I rode a '09 250xc-w for one lap on a track and it was adequate on jumps and felt awesome in the whoops. I was actually quite blown away. The suspension was just super smooth/planted and even though it didn't rev, (like I prefer), it could still be fast (by 125 standards). But, it felt heavy. And not near as flick-able. If the '08 is lighter AND shorter, plus more power.....it might be just right. So to recap. I don't want to move away from light/flickable. I like to rev. But I want a lower seat height and slightly softer (initially) suspension would be beneficial. Is the '08 actually lighter/shorter than other years? Who's specs do I believe? Make a switch?
  2. My brother was rebuilding my top end for me on my 2002 yz250, and due to a failure on his torque wrench, he over tightened and snapped one of my studs . Now i only have 5 of 6 working bolts on the cylinder head. I have 2 questions. We are supposed to be leaving for a 5 day riding trip in a few days, so we don't have time to order a new one. A: can I achieve enough compression and avoid any disasters for one week without 1 of the 6? b: There is a pretty awesome machine shop by his house that may be able to make us one, but I can't locate the specs. Does anyone have the exact specs for a 2002 yz 250 cylinder head stud? Any and all help would be much appreciated.
  3. Can someone tell me the manufacture specifications for valve clearances on a 2002 yz250f??!? I’ve looked some up and seen some videos but the more information the merrier right?? The manual I ordered hasn’t been delivered yet....
  4. Hey guys - I recently purchased a 1988 XR250R and took my first ride this past weekend (love it)! I'd like to check the valve clearances - I've seen conflicting info and would like someone in the know to confirm for sure. One place I read said Intake should be 0.05MM/0.002IN and Exhaust should be 0.08MM/0.003IN Another said Intake should be 0.10MM/0.004IN and Exhaust should be 0.12MM/0.005IN Can someone confirm for certain for me which of these is the right answer? Appreciate any feedback
  5. Anybody have Yamaha valve clearance specs of 2016 and newer 708cc engines on Grizzly or Kodiak?
  6. Hey First thread ever in a forum I'm desperate to get these crf/Excel wheels onto my '96 xr600r If u know how hard/expensive it is finding xrr hubs/wheels u know why I'm pursuing adaptive machining instead of building another wheelset with the Excel hoops I don't even know if spoke/hub angles match up with the hoops anyway So, i saw a couple drawings posted of the specs for spacer collars/sleeves and thought i hit the jackpot, but with further reading, it broke my heart to find those were for xrl, which i believe it's enuff different to not work on my xrr Definitely want rear wheel adapted, but up in the air about front cuz i also have usd fork set from the same cfr and may just do a full front end conversion. It'd be cool to have that 11mm main cylinder of cfr too for my street riding ?? Any help ? Thank u ahead of time
  7. Anyone know the crankcase oil capacity for 1976 yz80? I can’t find a spec for it anywhere online. Thanks in advance!
  8. I have looked all over and cannot find a good accurate resource out there. I recently decided that it was time to tear into my 1990 DR350S. (suzuki) it would not run reliably or really at all anymore and I found that the compression was only about 80PSI. After tearing into the motor I found that overall it was in pretty good shape.. the Oil ring was stuck inside the piston so that it was not sealing well and it appeared that the valves may not have been seating well. Really I figure I can re-grind or re-seat the valves, replace the top end gaskets and piston rings and it should be good.. what I am wanting to know is how do you know if you should replace more (valves, timing chain, ect..) I do have a strong Mechanical background but have never liked or done much engine internals.. any advice would be greatly appreciated. I do have pictures of the valves.. you can see them here https://goo.gl/NH76kw... let me know if that does not work and I can copy them to this post.
