    Playin in the mud

    Any one use or here of these guys Cycle Works Racing . I'm wanting to do a little work on my KLR 250 . I like a little more umphf and thinking about this kit . 280cc - Piston kit, just bore out stock cylinder, 11.8 to 1 compression with gaskets
    $255.00

    CWR fun power kit, 280cc piston, gaskets with valve seals,380 cams, rocker arms, valve springs, with your good cams and rocker arms in exchange $765 retail
    $710.00
    I've never had cams built up and re ground before . I don't know if any one out there has had any luck with it or not .

    I got my cam and rockers done by Megacycle through XR's Only. As long as both the cam and rockers are hardweld they will last a long time under some pretty severe treatment.

    Sell the 250
    Take the $700-800 and put it towards a 650.

    OR gear down the 250 and live with it.

    big bore 250 is a waste.

    John T has it.

    I can understand if inseam is an issue but boring the 250 is wasted money. The 650 is way more versatile and I am quite happy with mine being bored out to 685.

    Re: Playin in the mud

    I bored and stroked my KLX300, Web cams,37mm fcr, some slight head work with a custom header and that thing screamed.It would stay out in front of any of the 250 four strokes and 99-00 YZ400f through 4th gear. Everyone said the same thing about that. Do what you want,your not building the bike to make them happy.Your the only one that can say if its worth it or not. Where do you ride?

    Re: Playin in the mud

    I've found a couple of service roads . They go into some large flats areas , of a couple hundred acres . I need to tag the bike so I can explore further away from home . I bought the bike cheep from craigs list , I should have bought one that was ready to go . I would of had the same money in it . It's mine now custom camo paint and all . I did a little reading on these bikes . I never knew that the military bought some with diesel engines . They will run on just about anything combustible . Now that would be cool too a smoker . Other than the lack of power .

    Dual Sports are great fun for exploring, trail riding and a nice change up from the street.

    here is my KLX 400 (DRZ400) Enough power to about anything. Heavier than a nice KTM but, not pricey!

    "too tall" is not a valid excuse to avoid any motorcycle.

    that is,
    if you are experienced.

    Re: Playin in the mud

    I went a lot deeper than I probably should have to mod an old XR250R. But its my toy and I'll play with it as I see fit. That being said... a modded up 280 with cam, porting, piston, exhaust and carb will pull like a 350/400 stocker and weigh a lot less. In N.E. tight woods trails that kind of maneuverability far outweighs speed and power. My 280 in the first three gears has all the power and torque needed to get me hurt just fine.

    It's using oil for the same reason the ZRX uses oil:

    I'm not sure if my plugs fit it. But a valve cover gasket set is probably needed at least.

    Re: Playin in the mud

    No I don't think so . I've twisted it up a bit 80 MPH on the speedo . And it wasn't well maintained when I bought it . It had been ridden VERY HARD . There's a little piston rattle when I spank it . So Quick where's my 1109 plates ? I'm not cleaning my bike until I get them .

    Seriously, yes it is the problem. It's a silent killer, so to speak. Remove the header and look into the exhaust port, one side will be oily-er.

    I'll call Monday.

    Re: Playin in the mud

    Just bought this from E bay for $ 85 shipped . Kawasaki KLR 250 Cylinder and Wiseco Piston/ Jug 020" (.5mm) oversized Kawasaki ATV Wiseco Piston. 11.5:1 Compression.
    Application:1987 thru 05 Kawasaki KLR250 Liquid Cooled . Not a bad price for my mud bike . I'm trying to decided if I want to put the cams in it (more than likely will ) . Which ones because the cost is the same . And I'm trying to decided if I went with the higher lift 380 if I would want to install the springs and hardened rockers or go cheap with the 350 lift (more than likely these ) and keep the stock rockers . Hind sight is always 20/20 we always want more power . But then again I don't want to drop a ton of money into it either .Which I have already done . I'm even thinking of doing something with the front forks . When I'm out there beaten on it I've bottom them out a couple of times .Web Cams also has a clearance on Kawasaki KSF 250 Mojave (ATV) (87-04) ; Kawasaki KFX 250 (ATV) (2004) DOHC 4v

    I got a 2004 klr 250 engine just sittin' in my basement 1850 miles... Sold the bike.

    I did the bore on another motor with the wiseco 11.5 piston, made no noticeable difference. My 86 was a good bit quicker than either motor in my '04.

    Just checked my factory manual stock cam # for 1985 thru 1988 are Intake duration 272 lift 35.52 mm Exhaust duration 280 lift of 35.64 mm . That's was the reason for the power increase . I just changed my order from the 228 grind to the 236 grind . Guess I'll put in the order for their spring kit just to be safe there goes my cheap up grade . Can't wait no smoke and lots more power .

    GOOD CHOICE... big bore kit without cams and springs is like kissing your sister. Increasing the bore size won't do much good unless you do a cam change also... need more "in & out" or "longer" to complement the bigger hole... were engines here... OK

    I'd been following this thread but didn't feel I should add my comments looked like you had plenty already and all good stuff.

    Good Luck... keep us posted when you get it completed!

    Thought I would post up some pictures of my grunge bike . I should have taken a few before I took it apart . Hope I never wreck it in the woods they will never spot the bike . Just waiting for my bump sticks to arrive . I think I need to go ahead and have the valves cut and guides checked as well . Name:  IMG_0160[1].JPG

    Re: Playin in the mud

    I did check my cam lift before I sent them to web cams . I already had the 35.52 and 35.64 cams in it . So glad I decided to go with the higher lift cams . I have been looking into up grades on the forks on the KLR forums . Seems just like the ZRX that we have been switching over to the ZX14 forks . They have been using the KLR 650 forks . I know that when I was riding with a neighbor he was riding a newer MX 125 2 stroke don't remember the make . I bottomed out the front a few times . But I was 40 pounds heavier then . But it still would be a cool addition . Any ideas on forks ?
