This week we added three more buddies to the COTT Vintage Enduro team. If you don’t have an old enduro you’re missing out. They need a little cleanup but are runners. The red DT actually has a wrangler jean jacket made into a cover with a serious fade. And if you needed any more reason […]
Since a lot of friends have been getting 70’s and 80’s Yamaha 2 stroke dirt bikes, and I’ve done this a couple times now on my CT1-175 due to the motor blowing up, I figured I’d do a basic write up on how to change the crank seals. First off… Why do you care and […]
I love the old performance modification articles. This guy Don Vesco looks like the man and apparently knows his shit when it comes to modifying 2-stroke bikes. If anyone reading this has any old enduro/dirt bike magazines from the 60’s or 70’s they want to sell, i’m interested.
Nice weather for some fun enduro trail riding through the kenso woods. So so much damn fun. Little 2 strokes are the best.
In the really early 70’s… Yamaha had these as their dirt bikes: – AT1 – 125cc – CT1 – 175cc – DT1 – 250cc – RT1 – 360cc All were 69-71 era, piston port motors, before Yamaha really knew what dirt bikes would become. And all were relatively about the same dimensions, just different weight. […]
We went back into the kenzo trails in the snow today. Way more sketchy than I thought. Basically you need studded tires.
I’m looking for more spots to ride dirt bikes around Philly. Comment and let me know if you know of anything else that is in the city limits or super close by in PA… not NJ. Also, comment if you know anything more about those spots I mention as I don’t know too much about […]
So… I’m really starting to rip into this jalopy. As I said earlier, the clutch slips like a mother fucker. It’s horrible. I really wanted to do Barnett springs and plates. I found the plates easily on eBay but I couldn’t find ct1 Barnett springs anywhere. On a whim I ordered dt175 springs since they […]
I’m slowly realizing I know jack shit about 2-stroke motors. I took my top end off. From what I can tell… Some dip shit before me put in a reed-valve piston into a piston-port engine. Let me back up a step if you know jack like me. Apparently in these old shitty jap 2-strokes, there […]
I bought an Enduro. $380 The good: It runs… kinda Cosmetically… it’s pretty nice… but just rough enough. The wheels are straight… kinda The seat is original and really nice. Inside of the tank is perfect. Carb is clean. Motor has 90psi compression. Probably do the Wiseco piston kit anyway since it’s like $40. The […]

I’m actually going to have a full-on 3-angle valve job done on this head next week. More on 3-angle valve jobs later… Regardless, I wanted to show the basics of lapping valves. Figured it’d be good to show a general overview. I made a quick video. I’m sick today… Hear me sniffling? This ring below […]
