I've been learning about the DR650 while I shop for a deal. The "algorithm" suggested your channel, and I'm extremely impressed! Your instruction, camera angles and lighting, and pacing is PERFECT. I've seen countless similar videos, and worked for/under many people over the decades, and YOU sir are a top notch instructor. I've subscribed, and look forward to whatever else your channel has in store. Keep up the great work.

I feel the spirit of the DR-BIG 800 is with us !

I rode a Ducati Monster for 4 yrs and currently ride a Kawasaki Z900RS, which I've been riding for 3 yrs, and have ridden multiple other motorcycles. Still, my friends DR650 was one of the most fun bikes I've ridden. I should stop thinking about it and get one, 😂

When timing the cam, I always rotate the motor in the normal direction a few times to make sure everything is right and then I always turn the cam the opposite direction as I'm checking timing to take up all slack in the pulling side. 12.5 years as a Porsche tech.

As a DR650 owner. I thoroughly enjoyed watching this beginning to end! Thank you for this extremely informative video!

If you really want the beast to come out of that 790 kit. Big valves kit , cams and big bore ports.

Great video. Thanks for sharing. This is a project I'm thinking of doing next winter. You make it look straightforward. Cheers.

A Master at work.

Sweet walk through. I bought my dr new and put 3k miles on it so far. Weight reduction was a great mod asthmaticly and for performance. FMF pipe unbaffled with jet kit really woke it up. I was thinking of doing the 790 kit next but I feel the high compression piston with cam will suit me better. I'm thinking titanium intake valves and hollow stainless exhaust valves. I'd like more top end out of mine. If my mods got me 40rwhp I'm sure I can get 50+ with high compression/cam and head work. I build Lsx engines for a living. I'd love to do big bore high compression but I don't want to dump that much money in my dr. Thanks for the post

Great job man 👍 thank you a lot 🙂🙂🙂

Thanks, I enjoyed that. Good job, God bless.

Votre vidéo est vraiment très bien faites. Merci pour ça.

cant wait to ride that bike

Honestly by far the hardest part of the whole project is putting the piston pin retaining clips in, they are no joke. If i were to do again i would find myself some pinch style ones, the cram lock ones supplied in the kit are very difficult to fit...though was a good time to crack a beer once they were in!

Hahahaha great video and I share your excitement but, watching this in anticipation for getting my 1st Dr650 (and 1st dual sport ever) next week while sitting here helpless with a broken collarbone in the meantime... So when you said that it's "hard to do with a broken collarbone" (coinkydink) laughed my ass off because I feel your pain brother 😂 got clipped on my v4-cruiser by a jackass in a Subaru on his cellphone... Thanks for teaching me my first few things about tinkering with this lovely machine, bet she's gonna roar. 🤘hope you have more vids on here after the 790 swap

Very good; thank you.

Very helpful, Thank You. Two things I did NOT see that I would recomend...A. Check the squish gap and adjust as needed AND B. If you install a new cam...it will require the proper assembly lube plus I'd use new hardened rocker arms.

Im a fairly mechanically minded person. Ive always been pretty good at traring things down and rebuilding them from memory. Never had the guts to try an engine. Im considering getting a DRZ. I fell like I could handle this. Excellent vid. Ty!

🤘🏻 PERFECT VIDEO BRØ🤘🏾 👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻

I found the only tricky parts to be removing the camshaft drive sprocket and getting the barrel over the new piston. Needed my neighbour to assist me. Everything is pretty easy if you follow the manual. Transforms the 650 into something exciting but kills fuel consumption. The TM40 return spring is too strong and you can get softer ones now.

Awesome video! I would love to see a follow up and review. I have a DRZ 450 with Hot Cam and flat side carb. I’m in the process of refreshing it and have always wondered if the 650 would be a better choice since I’m not racing the DRZ any more. I like that it’s air cooled for the most part anyway. I have alway like the Honda 600/650’s for that reason plus growing up in the 70’s thos we’re the hot ticket in the NE. Thanks for the content, it’s first rate!!!

Does this kit run a similar compression ratio to the stock cylinder? Would be nice to keep it low.

Pro Cycle has great after market parts for the DR 650.

is there a part 2 it's a wonderful video very educational I have learn allot thanks very much for making such a wonderful video

Excellent easy step video. Most people should be able to give this a go in their shed. What sort of horsepower numbers are expected once complete?

do they sell kits to replace the cross tip bolts for hex bolts?

Thanks for sharing that - the big bore kit has been on my wish list for a while, so this will help when I pull the trigger on it. I see you kept the stock head and valves. I know Pro Cycle has the larger valve head available, too. I’d expect that to give better top end power, perhaps at the expense of low end torque. Why did you stick with the stock head, if you don’t mind my asking?

Just about to put the cylinder on my 790. Just wondering if you used the stock ring clocking out of the manual or if you just placed them 180° apart

DR800 DR BIG has entered the chat ! ;) browahahaha

Interesting, I'm working on a xr650L to xr806L.

Can I do this on my DR 600?

Whats break-in like after one of these kits is installed?

It would have been nice to hear it start up and run, if you can put a future clip in there depending on when posted and such. I'm looking for the continuation now.... Bless.

The only thing my DR is missing is the 790 kit....the temptation is real!

How’s The 790 build coming along? Interested in the finished project.. Great clip btw 👍

u r are insane

So how much did it cost for all the mods and upgrades? How many labour hours?

I am seriously thinking of purchasing a good used DR650 with the 780 ProCycle kit - wondering how you like your 790 - if you think it is as reliable as the stock 650? Also do know the difference is between the 780 and the 790 ? Thanks for your thoughts.

790 air cooled ... that's a crazy sight

Where is the link to the next video after this?

I need that rachett tool! What's that called?

Any follow up on this bike? :)

Just buy a bigger bike. Did enjoy video. I dump muh bushpig 4 the 5th time putting it on jack stands. 5 dumps in first month........

I'm new to this channel, what year is this 650? I'm needing a ton of knowledge..

How many miles is on that bike? looks like the oil rings were shot.

Now all i need is your address… Surly you won’t mind 1 more DR to work on! 😂

A different kind of DR Big.

Is this procycle piston non-directional?

god theres like 9,000 things that can go wrong doing this.

Why didn't you ride this thing and show us what it can do ?

790 too over square, stop

790??? Its too much worm for this engine 🤣🤣🤣🤣🤣
