6,500RPM 196CC Go Kart Race Motor!! | 15HP Honda GX200 Clone High Performance Build!

- Опубліковано 16 лют 2022
- In today’s video, I pull apart my old Hensim 6.5HP 196CC small block motor that I got off of a Baja Heat 65 fat tire minibike a while back. I then hone the cylinder, clean everything up and put the motor back together. Then I install some performance parts, get the motor running, and see if it can actually rev out to 6,500RPM with a stock cam/stock bottom end. This motor is an absolute beast to be a stock cam/stock bottom end and stock head motor!! So with that being said, we really hope you enjoy today's video!

So awesome build man!, these engines are crazy funny!
Nice SC Rambler.
no way possible with a 196 stock bottom end stock cam and a chikuni 22 carburetor you making more than 9hp on best day. I just finished building a 196 for my friend, Tillotson 196rs crank, .356 cam, billet tappet lifters, gage 1.3 black venums, stage 4 head, +.020 rod, flat top piston, mikuni 24mm flat slide, billet flywheel with 34° total timing set to .035 spacing with the coil, and it makes about 17-18hp. put it on his doodlebug db30 with a max to 15t and 72t split sprocket, sun f road tires front and rear discs with go powersports front end swap.
Even if I did nothing else except a carb, exhaust and Champion rockers I’d at least be at 10HP. Years ago a Champion 196CC motor was put on an engine dyno with a re-jetted stock carb, an open air filter, a pipe and a full governor delete. It made 10.5HP in the upper 4,000RPM range. This was more than an early Predator 212CC running the same test; same dyno, same mods, etc. These little 196’s are sleepers I’m telling ya
@@JM.Performance Billet rod .HOT365 cam complete governer delete 24mm NIBBI with 130 main jet straight header should make a few horses IDK how many
@@JM.Performance Any stock Hisun/Honda clone flywheel revving to even high 4k RPMS is dangerous, the stock connecting rod has no bearings so you will ware the crankshaft and your connecting rod, not only is it cast aluminum, the oil dippers are prone to snapping because the stock cranks are very imbalanced and only balanced for 4k at most, a amazon carb will not be accurate or drilled to spec, I have done multiple 212 builds and i will tell you from experience, do not ever bypass/delete a governor, you will get hurt or explode a 3LB cast steel flywheel. also I don't know where you get your dyno runs at but it sounds like they need to be calibrated
Dang man just seeing this. Your lucky that flywheel didn't frag on ya. Nice little build
Might as well to get some stainless steel push rods too and a Boris racing head stud kit to
Yeah I’m going to look into aftermarket push rods and a stud kit soon, after I put a cam and billet internals in this motor.
Low rpm for 15 hp, I rip 8500 on a 212 all day. I would suspect you are closer to 8hp
I thought just a stage 1 kit makes 9-9.5HP, and I have a lot more done to this motor than just a stage 1 kit. Correct me if I’m wrong though.
@@JM.Performance Even if you did nothing else except carb, pipe, and Champion rockers it's at least 10 HP. Years ago they dynoed a Champion 196 with a rejetted stock carb, pipe, and no governor. It got 10.5 HP in the high 4K RPM range. This was more than an early Pred 212 in the same test.
I have a Coleman with a mildly built Greyhound 196. With a torque converter and better than stock gearing it seems more powerful than it really is. Does very well as a trail rider.
@@Deucealive75 Hmmmm… that’s very interesting information. We actually have a built GreyHound 196 as well we’re going to be showing on the channel here soon.
8500rpm on this kind of engine?? What mods do you have
@@Fiatfanones that dont exist lmao
Great video and budget build! What jets on the VM22 did you end up with on the main and pilot?
Thank you I really appreciate it!! It’s a VM26 with the same jets in it that it came with when I bought it. Since it’s such a big carb for a stock cam, stock bottom end 196 it was a little rich at first so all I did was move the clip on the needle to either the second to last leanest setting or the last setting (as lean as it will go). It seems to run pretty good like that, I can’t remember which setting I put it on but it’s one of those two.
Great job, but I wouldn’t rev it up to 6500 or even past 5000 with that stock flywheel. Definitely need a pvl flywheel or a billet, I guess your on a budget just like me?
Thanks man!! Yeah I’m kind of on a budget right now, I’m going to look into a PVL flywheel and billet internals hopefully here soon… planning to put a 212 or a 224 crankshaft in it and make it a lil stroker
@@JM.Performance the 212 crank would work and put the piston at a zero deck height and turn it into a 200cc. The 224 wouldn’t work without a block extension or a short rod since it’s 3mm longer than the 212 crank. I want to do this as well to my hisun engine. It already has the max stroke crank off of omb it’s only .010 longer. And I wanna get a 14cc head with 5mm vavle stems and make a big vavle head that’s milled and ported/ polished. And bmi carts sells .020” over pistons I wanna do that to but may never happen.
@@connerdavis2450 Yeah that’s awesome man, and thanks so much for the information. I want to do basically all of what you just said to mine as well, that’s end goal for me. 212 crank, zero deck height, ported and polished 14cc head with bronze valve guides and bigger valves, billet retainers, flat-slide carb, decent cam, the whole nine yards. Hopefully this summer I’ll get around to it. We have a vintage racing kart frame I want to eventually put this motor on
@@JM.Performance would be a bad cart!!! Mines going in mini with a 30series converter
@@connerdavis2450 Oh yeah that’ll be one bad minibike as well!! Especially with a 30 series, I have a Juggernaut right now waiting to be used on a project
I honed about a 1000 cilinders in my life. Learned it from an oldtimer. Honing should be done at very low speed. If you take a very close look at the finished cilinder wall you should see sort of diagonal stripes at 45 degrees. You can only achieve this at a very low speed.
Yep; crosshatching. Helps seat the rings. We made sure this one had great crosshatching before we finished the hone job.
Good luck 6500 RPM with a stock fly wheel brother I hope you don’t get a magnet through your leg good luck, try to get yourself a better fly wheel they got a lot of options that could reach 10,000 RPM and it’s not billet, Sometimes I kick myself in the ass for buying Billet it’s like a piece of jewelry that’s hidden. I tried the plastic see-through cover makes the bike look cheap anyway I hope you’re safe
Thanks. I'm looking into either a PVL or a Billet Flywheel here soon... along with billet internals (billet connecting rod, etc.)
Great video. Sounds like it's running too fast though
Hi there, wondering if you can help me, I have a gx160 and it starts but as soon as I put my foot down the engine dies.... I'm struggling to adjust it and would like to get some advice please
Watch gx160 carb adjustment videos. I have zero patience for it and these UA-camrs can learn you a lot
My honda gx 160(governor delete) revs like that(probably even higher) with stock carb and exhaust
Yeah I believe it, them little 160’s are monsters… and they’ll rev to the moon. Only 160CC’s so there’s not a lot of engine rotating mass.
Risk to blow your engine....
I wanna hotrod my Pressure washers..lol
Snowblower… 😂
Tui muốn mua 1 máy 18hp bên nước bạn có thể nhập về vietnam với giá rẻ không
What exhaust wrap is that?
Design Engineering (DEi) Header/ Exhaust Wrap
I have a stage 1, pvl flywheel,30$ 272 cam 50$ + torque converter I can race dirt bikes on the trails
Nice!! That sounds like an awesome little budget build, how’s that .272 cam treating ya? Where’s the power band at? Up top, mid range, or down low, or a mix of those three? It sounds like a pretty powerful motor if you can race dirt bikes in the trails!
15hp with stock internals?!?!?!?
Yessir!!
Size Valve bro?
Stock sized 196cc valves
Great to see you having a go yourself, best way to learn. When your budget increases get a PVL flywheel as others have suggested, as I’d hate to see you hurt by an exploding flywheel. I built my sons kart engine for an open performance four stroke class in Australia and it’s a 228cc based on Tillotson 72mm bore block. It’s running a ARC billet flywheel and conrod, Tillotson piston and rings, stroker crank, ported 22cc head machined 20 thou etc. No idea how much power it has but it’s enough to win races. Link below to one of his race wins, kart #26 below:
ua-cam.com/video/-bx2GiqBZGk/v-deo.html
That’s awesome!! I just finished watching the video and man is that kart fast. I’m definitely gonna be looking into a PVL Flywheel and some billet internals here soon… once the budget increases. Yeah that’s awesome though, I’d love to build either a 225 or a 228 Tillotson one day as well!
Hi there im having problems with my gx160 engine and wondering if you can help me... It starts up and runs but when I put my foot down it dies.... It was shooting flames out the exhaust when I took my foot off the gas but its been messed around with since and now I can't gwt it back to how it was
@@wildw77 It sounds like a lean condition to me… make sure your carburetor is 100% clean and make sure you have 0 vacuum leaks. If it still does the same thing I would try upping the main jet in your carburetor. Try running it without an air filter/ air box (not sure what carb set up you have) and see what it does… if it gets worse then yes it’s lean, if it seems to get a little better then it could be rich and the air filter/ air box is starving it for air. Try it out and see what happens, I’d order a variety of jets just to be safe. If none of this seems to work you could just have a vacuum leak you don’t know about or it could be spark/ ignition related. I’m positive it’s just lean though.
Thankyou
@@wildw77 No problem!!
I Race A Honda Super Stock Engine With a pipe similar to that
Try a TM24. WAY better!!!!!!
Yeah we have that carburetor on our 196CC Greyhound and it really is so much better. Another TM24 is definitely what’s coming in this motor’s future, along with a cam and a few other goodies.
İğne nerde
I didn't hear you say anything about a port job?
Yeah man, I forgot to mention it in the video but yes, the head has had an extensive port job on both the intake and exhaust side, as well as a decent polishing job on the exhaust side. The bottom of the head has also been shaved down to the first row of fins… it was on VP 110 octane race gas in this video as well for the hotter plug and the extra compression.
Decir en español
too many tight bends on the exhaust pipe. loss of power there. need smoother bend and only 1 bend on exhaust pipe
Yeah that’s what I was shooting for but I made this exhaust out of existing pipe I had laying around, it was free, it gets the job done and it sounds amazing in my opinion. Once I throw a cam and a few other things at this motor I’ll for sure look into a more straight shot header with less bends, as well as a more freer flowing silencer like an RLV.
@@JM.Performance great job on the motor though. sounds good !
Much appreciated!!
Sounds low on oil
It wasn’t, just bolted to the stand by only one bolt so it sounded the way it did lol. I’ve checked the oil every time I run the thing.
Why on earth did you not add a cam and FW? You could have got way more power out of your build.
I wanted to see how much I could get out of a stock bottom end engine. Tests coming soon…
...clickbait!
No why?
