I Bought a MONSTER Honda TRX 700cc (Super Risky Buy)

"It just stopped working" Translation "We heard a big noise and then a crap ton of clanking around until it finally seized up."

Man I have quickly become addicted to your channel, this is rad ass content and the vlog style going to buy then fixing is making them all hits. Congrats 👏

Watching this shows something important that I need to work on for myself: treating each task as a voyage of discovery instead of a major catastrophe. Total zen. No stress. Well done.

Get a boreascope and take it with you on your inspections. It's a great tool that will save you thousands and help the seller to remember what really happened to it. 🙂 It will also give you way more leverage on the amount you are willing to pay. You might have been able to get it for $900 - $1000. If they won't allow you to scope it just walk away you'll be doing yourself a favor. You will know they are hiding something!!!! Great teardown and assement back at your shop.

If I had to guess. It was a chain reaction of events. First started by the lexx pipe and cdi box upgrade. More exhaust flow due to enlarged pipe and adjusted fuel map due to cdi upgrade Which in turn allowed to rev higher and floated a valve. In turn piston meets valve and boom bob's your uncle. The hole in the piston is from the valve stem giving it a little pokey pokey. Imo. I'd go back to stock. This particular machine is very robust right from factory. After market parts destroy machines at least in my experiences. For general all purpose riding, stock is the way to go. Just my opinion.

Great stuff sir! I’m not even into ATVs, but I enjoy learning stuff and understanding how everything works. You’re highly skilled. Thanks!

I have the same bike. The seller did the same thing to me…..said he was riding it and it just stopped. Told me it was the solenoid stopping it from turning over. Paid “$1,700”for it…..must be the scammers price for exploded 700’s. Hope you put out more tutorials so I know how to repair this thing. Up until your video no one has put anything online about the Honda 700xx.

Awesome video man. Good luck with the rebuild. I'm not familiar with trx700 but I've seen that kinda damage from downshifting instead of upshifting. Engine spins to fast, valve springs can't keep up and piston makes contact with the valves. At least it's in good hands now.

I've said it before I'll say it again. I love how calm and methodical you are. I wish I could be mire like this when I get into projects especially when unexpected problems arise. Looking forward to the 300 being finished as well. As for this I'd go big bore. You have more proof of work than almost any reseller. You should be able to get a premium for this when it's all said and done. Keep up the great work.

Sorry to see all the damage. I would remove that aftermarket tuning box. Seen them break before and leaned out the engine. Good luck with the rebuild.

Loving your channel!! Watching your shows everyday lately. I’ve grown up with motorbikes so it’s great to be learning so much about the inner workings!! Thanks for sharing . Keep doing what your doing 👌Reuben from Queensland Australia

I think you should do a complete engine rebuild. Why? Because I am doing that same thing on my 700xx and I could use all the help and advice. LOL! I had metal shavings in the bottom section.... My cam bearing(s) failed and caused huge damage. Can't wait for the followup videos on this. Great job!

I’m wondering if that tuner box removed the rev limit and it was over reved and then boom!!

My guess is valve failure, too. I’d stick with stock bore and all Honda parts, rebuild it and flip it. Great video!

this seems to be the best small engine repair channel on the tube, thanks!

Awesome video. I always enjoy the work you do on quads. This particular one...well, it sucks how bad it is. As for me, if I'm keeping it, I go big bore kit no doubt. It sounds like you're wanting to sell it after its fixed so knowing these machines are beasts in stock form, why pay the extra money into an already expensive project?? Can't wait for part 2 and see it all come together.

When you're getting a good deal you have to assume the worst and not take seller info at face value. That usually works in your favor except for when it doesn't. When it doesn't, we get some great content and a real world idea of the risks associated with "needs work".

Also check your oil reservoir in the bottom there's two screens in the hoses that go in sometimes when you replace the o-rings in it you bend those screens and you don't get oil flow to your motor you restrict it and they clog up and everybody forgets about them so you might want to check those out too the black oil reservoir canister the screens are built into the hose on the bottom

Hey great video/content! Can you show more of these pre-sale negotiations. Cheers

Love you videos. Thanks for raising the value of my 700xx I swear no one knows about these gems. I just snapped the crank in mine last night so it’s funny this just popped up on my feed. Please let us know if you find cause I’ll be searching for mine!
