Jake's Honda Trail 90 Project - Part 3 - Seized Piston vs. Hammer!

Part 3 of the $60 honda CT90 project. This video focuses on freeing the rusted stuck piston and engine intake / exhaust valves. I had to use much more force than I would've liked to free the parts.

Sweet Crocs I wear mine when I’m working on my ct-90 too

Hey jake on a side point, anyone ever said you've got the look of a young sly Stallone....

[@tyrssen1]

Very cool, Jake! I've just acquired a Honda 400 twin with an engine that looked decent on the outside, but is is stuck -- and I'm betting it's just the pistons. This vid offered some great tips, thank ya!

[@maporules]

How luckys that! motor was stopped and parked while piston was on tdc!

[@marteck319]

Invest in a propane torch, A fabulous tool for working frozen parts loose. On the cylinder does he do cylinder all around for 1012 minutes. Spray the penetrant on the piston just as you did and let the heat dry the penetrate in. On the cylinder head ditto with the valve it will work like a charm. Patience to let the heat work.

Moore! :D Love these episodes :) Just put everything in diesel for some days and let the rust just poor off ;)

[@terrencetoussaint4709]

thanks exactly what i needed for my ttr90

[@Dan-qp1el]

Nice video........I expected it to look worse than it does.

[@todcooper4707]

good job ! looking forward to see her run . i am going to spray the sp`s fuel tank today with red plastic dip . i send you a pic if you want to see it .

[@jenniesgarage]

That first start is getting closer :)Good idea about the plastic dip, I bet it turns out nice.

[@robstevens9667]

Very good 👍 very helpful ty 🙏

[@mordantly]

Red headed piston. Lol. That was my stage name.

[@HorsepowerGarageVideos]

New piston and rings, maybe valves, clean up the head a little and should be a runner.

[@jenniesgarage]

I'm optimistic about it. The more stock parts I can keep, the better!

[@baisleyde]

can't believe what I'm seeing on this video , I thought you were allergic to gloves

[@newwavepressure6478]

How would u clean the valves and piston or did u have to buy new ones I've never done a engine but I have a palaris that's bin sitting for a couple years about four and I was thinking of getting it going again

[@harryfp1494]

Hey next time try drain o or clr it works great

[@zx8401ztv]

Thats brilliant!!, with patience/skill you have teased the parts out. And i dont mean blowing raspburys at them while using your hands as antlers ha ha :-))) You might be able to give the top of the clylinder a carefull rub with wire wool or brillo pad or 2000+ grade sand paper to smooth the rust down, i bet the piston would polish up as well :-)) If the big end connecting rod has no push/pull play then your really doing well :-))

[@jenniesgarage]

Tease is definitely putting it lightly, but I think the parts will be ok (mostly haha). I was really happy with the feel of the big end bearing, if it turned out that the bike needed a crank, that would've been rough.

[@zx8401ztv]

***** You did really well, i have frends that would not give a second thought to hitting the piston with a lump hammer, the engine would be distroyed. In your hands that engine will run again :-))

[@richardvarden543]

i reckon that frozone would also have been a good name for her

[@TravieSpots]

Did you end up selling this engine after the 125M swap?

[@jenniesgarage]

yes, hopefully it's running around somewhere

[@ford1016]

maybe the intake valve was siezed shut because she only wanted to let it gooo!

[@autoandcribtoursspacemintc3123]

my piston is siezed in my ktm 50 what should i do

[@peytonmcadams7562]

autoandcribtours mintcondition you blew it up. take the top end off, re-sleeve the cylinder, and get a new piston kit, if you're lucky that's it

[@tacticalmosquitoeater]

autoandcribtours mintcondition sell your ktm and buy a kawasaki

[@Maarlooonnn]

autoandcribtoursspace mintcondition try and unseize the piston with wd40 and if that doesn't work try tapping on it with a wooden rod, when if you manage to free the piston check for scores on the piston and cylinder, and try and unstuck the piston rings without breaking them, if this doesn't work get a new piston, and also a cylinder if needed.

[@daithesilverdollar7787]

When are you posting part 4
