Its made Eric Oldham, unfortunately he does not make them anymore. They show up on Facebook or ebay every once in while.

It was purchased from OMW Racing

@@kurtboyko4446 does he still sell them?

Unfortunately no, he sold everything a year ago. The guy that bought it all is Danny, dont remember his last name and not sure if he is doing much of anything

No, its 13 to 1 compression. I run it on C12 or 108 octain

There are a few other video's loaded up with the whole bike

Have not had a chance to dyno it against the Ron Woods pipe. Was hoping to do it in a couple of weeks in Idaho but my usually guy is to busy. I made 59 HP at 5000 feet.

Does it run normal otherwise? It has too be something in the timing or fuel mixture. The only that happens is it pushes out the valve cover gasket? Have you checked the breather tube?

@@kurtboyko4446 it runs fine other than that. Starts fine runs smooth no power loss. I have checked then lines and can push air through them. On the oil connection on bottom of crankcase it pushes oil. Have not check top connection on top of crankcase. It real hard to find people who have knowledge of the ds in south Carolina. Just trying to get info before I start tearing this thing apart. Havent tore one down since 2006. Thank you for knowledge

Try pushing air through the crankcase vent tube. It comes off the engine on the brake pedal side just under the exhaust. It ends in the air box.

@@kurtboyko4446 the line coming out of crankcase on brake under exhaust side close to motor mount I can blow air through but they have it on a Y connection running into oil tank not airbox. Does that make sense?.

It Y's with the line coming off the top of the valve cover and both connect to oil tank connection below fill cap

Ryan, IT'S been a couple of years now and it still runs like a clock. I ride it a fair bit and always drive it like I stole it. You don't want to wait until you have a problem without the shim under conversion. Do it now. Get a hold of Eric Oldham - he knows the DS motors inside out.

Ted, yes I still have it and yes it is super reliable. All the parts are still available. When I dynoed it in St. Anthony's sand dunes at 5000 feet of attitude it made 59 horse at the wheels. There is not much that can beat me, dont forget that the DS weighs 100 pounds more then any other sport quad. I love it and will keep it for ever.

@@kurtboyko4446 where all the parts are available bcz i wanna custom mine too like tht bruh plz help me bro

@@emmanuelcine3541, yes contact OMW Racing. They still make all the parts.

@@kurtboyko4446 how can i contact them bro??

john b - the next step I would take is a replacement Carburetor. You will need it after if you want to keep going. It will stay make a hugh difference on a stock motor. I would suggest a Lectron from Eric Oldham at OMW Racing. You will also need an aftermarket throttle to open up the carb all the way. Careful power is addictive - LOL.

thank you ! placed the call for carb info and will ask about the aftermarket throttle. bought this bike on a whim and ..wow..love it.

​@@kurtboyko4446picked up a 650 Baja not too long ago. It's got all the standard stuff exhaust/over rev and such in thinking about going for a lot more out of it. Is there a build sheet you have for your unit because it looks insane

@austinjackson7298 , best watch my DS770 walk around video. It gives lots of details. Unfortunately Eric sold the business to another guy. He may start building the kits again

m.ua-cam.com/video/yxMOowk8EGs/v-deo.html my ds at 1:40 and 27:50👍

Badabing313, yes I had it on the dyno last year in St. Anthony's Idaho. At 5000 feet of Altitude it made 59 horse at the wheels.

you ride a ds up at tug hill to? I have 3 of them I run up there.

john b - The engine has a 105mm big bore cylinder and a 5mm stroker crank taking the displacement to 770cc. There are a couple of other videos of the bike on here under DS770.

thank you!

Ricky Geneau , just so you know - this dyno run was done in St. Anthony's Idaho attitude is 5000 feet above sea level.

Kurt Boyko what does altitude has to do with the dyno? You set your jetting according to the altitude?

Ricky Geneau , you commented that my horse power number was low. I was extremely happy with the 59 horsepower my 770cc engine made due to the fact the St. Anthony's is at 5000 feet above sea level.

I wonder what it could make at 500 ft

@@ickytechtips from Sea level to 5000ft your losing a lot of power because the air is thinner and you gotta jet much leaner! The More fuel you can feed an engine the more power your gonna make! Only thing that would help him compensate for the lack of oxygen because of high elevation is NITROUS OXIDE 🤙👌🤣

Brandon it coming. I am in the process of building a new bike now. Bought a 2007 DS650. Frame is going out for powdercoating this week. New Fireball Racing A-arms, +4" swing arm, + 2" steering stem, Elka shocks, new decals and lots of other parts. I am transplanting the 770cc power plant into the new frame. Will do a walk around when its all complete.

oh there is a god* cannot wait my friend

The 770 sure makes that DS behave like its 100lbs lighter

Thanks Nathan

Kurt Boyko I have an 03 DS, so I gotta ask the obvious question. How much did that motor cost in parts alone?

Brandon - you need to join the DS650 owners group on Facebook - lots of pics, Videos, and tips

i never signed up on the facebook :) maybe i should try it out

Brandon i just uploaded 3 more Videos from my trip to St. A's dunes from last June.

Just posted a ridding video Brandon

Kurt Boyko where is it?

Yup, I was happy with that.

Thank Brandon - I am just in the process of uploading the video from last week when i had it on the dyno.

Mines got the small vent line that goes from the top of the case to the top of the remote sump and I still bleed it anyway every oil change because I’m paranoid. I also just started putting a dab of never seize on the bleed screw. That bastard can be tuff to crack loose! Much easier to crack loose now each oil change.

@@badabing3136Sorry, I know this is an old post but I have an 05 DS650X. Can you please tell me how to bleed the system? Do I do the oil and filter change first, then remove the filter and then remove the bleed screw? (How much oil will come out before I replace the bleed screw?) then do I replace the bled oil back into the reservoir tank? Thanks for any help.

There's a light that lights up

Sow it is, oli out en filter out and new oli en filter in and done? 😬

What did you fix on it ? Trynna figure out what’s fixable on my 650, in need of rod bearings but can’t quite find anything

⁠@@rclgrimmzy3238 reach out to CT racing they are a machine shop and they will rebuild your crank for $100 labor + whatever the bearing/bushings cost. They also have a ton of parts for the ds650. Hope this helps

Hahaha You’re kidding right? This quad has a 770 kit from OMW racing. A renegade 1000 is a kids toy compared to this machine. Not even on the same playing field, this quad would completely destroy a Rene 1000 that weighs 800lbs. (owners have proven the 700lb factory weight is complete BS..)
