    08 head on 06 crf 250r

    How good wod a 08 head work on a 06 crf 250r would there be any differences? Thanks
  2. so I am building the bike up at moment as I done the top end, barrel all went in fine, rings set perfect as per manual, chain guide was put in place before putting head on and fed chain to top of head, torqued all head bolts to spec then I am scratching my head.....exhaust cam in first with timing marks as it should (bike is at TDC) then trying to get the inlet cam in just seems impossible, I watched a few videos and the chain simply slips over the cams, there is no tensioner in place on my bike but there isn't enough slack in the chain to make it simple, can anyone give me some guidance or throw some thoughts my way so I can have a look, the only thing I thought was the chain guide closest to the exhaust cam was incorrectly fitted but again I have watched videos and mine is sitting in its position on the head. any help would be appreciated. thanks

    Yamaha YZ250F (2006)


    Wish I bought a 250F years ago! Love this thing! I'm not a MX racer but a like light bikes for trail riding and the 250F works perfectly. The 250FX is probably where it's at, as this bike's gearing isn't quite wide enough for the fast/open stuff. Riding on some of the 2 track and roads near Moab UT I found myself pinned in 5th a lot. The suspension is great stock, the fork is a little on the stiff side for my liking but I'm swapping to lighter springs and will opt for a revalvle if it's still too harsh but for a MX bike it works really well as is on the trails.

    Suzuki LT-Z400 QuadSport Z (2005)


    I've had hours and hours of fun on this quad. I can say I shouldn't have bought a new one then dumped as much money as I have into it. Instead, I should have purchased a used one then sold it for a 450 or 700 to feed my need for more power and speed.

    Top End Advice

    Have a question or 3. Have 74 documented hours and about 15 non-documented - so around 90 hrs. I've owned quite a few bikes over the years, but never owned them long enough/rode them enough to do a top end, so this is my first. Piston and cylinder are w/i spec. I did not check ring end gap. Couple weeks ago I checked compression and had 220 or 225 psi. PV, etc. was not very dirty at all. I burn C12 and K2 at 32:1. I've never fouled a plug, but it does run a bit rich. Many jet changes and clip experiments led to arrive where it's at. Any leaner with the main or needle and it seems like it's starving. Plug isn't light brown, but it's not black either. I ride trails and spend most of my time at closed to 3/4 throttle, with occassional blasts at WOT. I have a new piston, rings, small bearing, piston pin, and circlips due to arrive tomorrow. First pic is the head exactly as it came apart. Looks good to me. Second pic is the top of the piston. Exhaust side is facing left. Does this look good? Third pic is the exhaust side of the piston. What's going on there - blow by because the rings are worn, or is this normal? Fourth pic is the bottom of the piston - shows no discoloration, etc? Think that's good.

    KTM 500 EXC (2016)


    What a machine! I picked up my '16 500 exc this week and got a chance to take it for a romp through Cleghorn trail in the San Berdoo National Forest. It rides like a dream!<br /><br />Prior to picking it up from the dealer, I had them add the Rekluse Core EXP 3. This is my first bike with the Rekluse. Love it!

    Kawasaki KDX80 (1983)


    Not really sure how to rate this bike but it is exactly what I wanted, small but not puny, does fine at slow speeds and isn't too crazy for a beginner. On the other hand, if you rev it up more and get into a higher gear it will go fast and give you a little zing

    Clutch Slip @ almost WOT

    At nearly WOT, most noticeable in 3/4/5 gear and leaned over coming out of a turn, it feels like the clutch is slipping. My bike is a 2007 SM w/18.4k miles on it with, to my knowledge, a stock clutch. If it helps, like most SM owners, I spend a lot of time on only the rear wheel. Anyone else experienced this? How to fix this?

    Suzuki DR-Z400S (2007)


    This is my 2007 Drz400s. Its had a few different identities over the years the latest one being converted to supermotard. I've had it since it was brand new and been modifying it ever since.
