    KTM 690 2017 gone?

    I've been looking at the KTM Canada website trying to decide between the 500 EXC and the 690 R and it's on the website for 2017.

    Building first supermoto bike

    No not a real helmet but cool none the less. Good for halloweenand that's about it. It gave my brother a good idea though, (I'm in a family of artists and the only one with no art skills) paint my new helmet white and put the star wars rebel symbol in the back.

    That helmet is badass. Thanks for the tip on the suspension. Wouldn't of thought it would be stiffer.
  4. Hey guys, been a while since I've been on here. Sold my bike CRF450 11 years ago when I got kidneydisease. I've had a kidney transplant from my wife for 10 years and I'm actually writing this from a hospital bed. Just had a kidney (luckily not my one good one) removed with a cancerous tumour on it and got word the cancer was self contained to that tumour and scans found nothing else in my body and I'm feeling great. It's time to get another bike and I'm looking at building a '17 KTM 500 exc-f and having the supermoto setup to swap in and out with the dirt tires and I need your help. Any help with this would be greatly appreciated. Warp 9 racing wheels seem to be most popular. Should I go for the 320mm rotor and adapter and is this necessary. Also what is a cush hub and is that necessary. What are the go to tires for supermoto for a good mix of grip and longevity. What are some good low profile mirrors. What is a good replacemt for the rear turn signals and license plate holder bracket to tuck them a little closer and look slicker than stock. Do I need to de-smog the bike to make it perform normally. What's some good engine oil and oil filter, stock or aftermarket. What are the best plastics for the bike, cycra, acerbis or oem to stormtrooper the bike (all white or black and white). Any must have accessories like phone holder and extra storage. Can't wait for spring. Thanks for your help guys. Look something like these bikes

    KTM 250 sx or 250 xc

    I don't understand people that think full size 2 strokes are scary and should only be ridden by a full grown man's man with many years of experience? If you can ride a motorcycle without whiskey throttling it then you can ride any size bike. You control the pucker factor by how far you twist it. Going from a 250f to a 250 or 300 2 stroke isn't a huge leap. I rode an XR80 for less than a year and then jumped to a CR250 and had no problem handling it, and I was short and not that huge. If you want to jump I'd go for the SX. I always rode stock MX bikes on the trails and preferred the lighter weight and snappy power over a cushier ride and extended range. If you ever want more power you can get the 300SX engine kit too. I did have a 300 exc and loved the motor but still missed the suspension that could handle big jumps too. I haven't ridden an XC but I hear they close that gap between track and trail.

    1996 RM 250 Powerband

    The '96-98 RM 250's had the crappiest motors out there. They were way down in power compared to the other 250's and had pretty "meh" powerbands. I don't remember exactly but I think it had something to do with poor powervalve design. I believe the valve was too close to the motor to work properly and a small fix to gain low end was to add a spacer to your powervalve. Unfortunately it's just not a good motor and you may have to live with the relatively flat powerband.

    Here ya go (hopefully). Here's my brother inspecting the machine before I take it on it's maiden (low speed) voyage. http://i498.photobucket.com/albums/rr341/BMayhew28/P9150638.jpg http://i498.photobucket.com/albums/rr341/BMayhew28/P9150639.jpg http://i498.photobucket.com/albums/rr341/BMayhew28/P9150640.jpg http://i498.photobucket.com/albums/rr341/BMayhew28/P9150642.jpg http://i498.photobucket.com/albums/rr341/BMayhew28/P9150643.jpg http://i498.photobucket.com/albums/rr341/BMayhew28/P9150644.jpg http://i498.photobucket.com/albums/rr341/BMayhew28/P9150646.jpg http://i498.photobucket.com/albums/rr341/BMayhew28/P9150648.jpg http://i498.photobucket.com/albums/rr341/BMayhew28/P9150649.jpg

    Luckily I managed to find the pics but not sure on how to post them so hold on and hopefully I can figure it out. It totally gave me a chuckle looking at those pics again and seeing how much of a redneck inspired build it was aka hackjob.

    Back in 1986

    My brother and I decided to build a trike after seeing the first concept drawings of the new Bombardier street trike. We had an old 1991 Suzuki Quadrunner 160 that had been sitting for a while that we knew was eventually going to be chopped into a go kart or something and then saw the Bombardier with two wheels in front and one in the back and we knew instantly what we were going to do. We cut the back end off up to the shock so we could keep that (this was a low budget, drinking beers kind of build) and welded on a dirtbike swingarm with the 18" wheel and brakes and voila, instant frankenstein death machine. We painted the whole thing silver and stenciled the name Johnny 5 on the seat (in retrospect it should've been named Johnny 3 but I mentioned the beers) after this short circuit bastard creation. Upon riding it we determined that this was the most dangerous combination known to man. Scarier than a bike, quad and old school 3 wheeler combined. And now it just sits back in the shed lol.

    New Fork design SWeet!!

    If you read the article the reasons behind the fork sound pretty good to me. After he road his new 1990 CR250 with upside down forks and realized how harsh it was through the bars and stutter bumps, he came up with an idea and scribbled it on a piece of paper. The upper part of the suspension in the triple clamps absorbs impact that would otherwise be transmitted to the bars. The lower tubes rebound quickly over consecutive bumps since they can extend quicker allowing the bike to track straighter. The whole otherside to the article was that this guy sat on the idea since 1990 after he forgot about it then decided to try and build this fork that he scribbled out over 17 years ago. Him and one other guy built this fork themselves and basically they're just putting it out there to garner some attention and hopefully get a company interested in some R&D money to really give it a go. The guy rode it and said it performed exactly as he imagined it back in the day some I'm sure it has real potential.

    Let's see your custom graphics

    Wow man that's a nice CR250. She's a pretty damn clean bike for being over 10 years old. I'm lovin the roulet rims that's awesome. I always wanted one of those 95-96 CR's when I a teenager and after seeing your bike I want one all over again... you bastard lol.
  12. You need to own the On The Pipe series. The footage is all epic and has top notch videography that looks excellent in HD. The Nitro Circus series is also good if you enjoy a little more randomness and jackassery with some CRAZY stunts.
  13. No problem, anything to save a few bucks and learn something in the process is always worth it in my book. You probably won't need the manual for the KDX as they're pretty popular bike and I'm sure other board members can steer you in the right direction if you run into problems. The carb is actually pretty easy to take apart and someone should be able to post up a schematic of it to help you out. I've been bikeless for a while but I think all you need to do is unsrew the clamps on either side of the carb and then unsrew the (4?) srews on the bottom of the carb (the bowl) and pull it apart. There should be a little wishbone shaped thingy with 2 little floaties on either side. That's the part that is probably gummed up and sticking not allowing it to close fully which would let gas leak out if it's stuck in the open position. The float valve thingy should be able to move up and down with the level of gas in the float bowl. Just keep us posted as you go and we'll keep helping you out and you shouldn't have any problems. I took my bike in the first time I needed a top end change because I too thought it was beyond my capabilities but the second time around I decided to do it myself with a little guidance from a friend and realized how easy it really is to do yourself. The best part is it will only cost you parts instead of adding another 50% for labour. You'll probably find you become closer with the bike once you've gotten to know it a little more intimately too. Also, when re-installing the air filter you can smear some grease or filter oil around the outside perimeter of the filter where it meets the airbox (as in right on the airbox itself where the filter contacts it for a better seal) to keep dirt from entering right at the airboot.

    The Moto X Myth.

    I just saw something about that on a science show and they basically busted it. It's funny because I even remember MC talking about it and how it didn't make his girlfriend happy (must suck when you race practically every weekend eh?). It was thought that you spent all your testosterone during sex and orgasm but the doctors stated that you don't lose or use up your hormones while having sex. In fact they came to the opposite conclusion in that it is actually beneficial to the body by releasing endorphins that relax the body and muscles, reduce stress and fatigue and may help you perform better the next day.
  15. I guess I'll be the first one to say it... it shouldn't cost you anything because those are all things you can do yourself. Taking your bike to the dealer to change your fluid and plugs and all that is a SERIOUS waste of money when those are the real simple stuff to do yourself, especially if you're cheap. Just find a service manual that will show you how to do everything you mentioned or ask for help on here and I'm sure everyone here can point you in the right direction. Warm the bike up then undo the oil drain plug and empty it out and fill it up through the filler cap. It should say right on the cases how much oil you need. To drain your coolant unsrew the bottom hoseclamp and pull of the rad hose and let it all drain out then re-attach and fill up the rad with whatever fluid you prefer (distilled water, coolant, engine ice etc.). Make sure to run the bikes and then re-check the fluid levels once it's had the chance to fill all the nooks and crannies. The manual will come in handy for greasing. Just pick up some good quality grease (bel-ray makes some good stuff) and find out where all the bearings are and be generous with the grease. Pull the airfilter out and wash it in soapy water. Do not ring out the filter as this may damage the foam. Simply squeeze as much water out as you can and hang to dry. When it's dry apply some filter oil and work it in but not too much or you'll clog the filter basically. Pull of the spark plug cap and unsrew it. Replace the plug with a similar unit, srew it in tight and replace the cap. The leaking carb is probably due to a stuck float bowl valves. Gas turns all gummy when it sits for a long time so clean out the carb with varsol or carb cleaner to unstick the float bowl or replace it if need be. That should fix the problem. All this stuff won't take too much mechanical skill really just time and elbow grease which is why these tasks are best to do yourself. It beats payin $50 an Hour for labour and you'll probably wonder why you haven't been doing this stuff all along. Good luck with it and just keep updating us as you go if you have any questions and I'm certain you can get through all of this without too much hassle.
