noob with yerf dog question

[minichoper]

Today i traded my homade mini chopper for a yerf dog 32001. The kart has a 7hp engine and a centrifugal clutch that slips. I dont think it came with such a cheesy clutch. What should this kart have for an engine and trans combo? I hope to be here for a long time to come.thanks

That kart would have came with a 6 to 7 hp Tecumseh powersport and a comet 30 cvt

i'd buy a 7hp 212cc to a 15hp 420cc engine for it depending on your budget and how much power you want and then either a 30 series with the 7hp or the 40 series with the 15hp.

 

[minichoper]

Intetesting, it has a suberu-robin 7hp. looks like a honda clone type of engine. As for the converter, i think i can get away with running a ebay copy of a comet converter. i had one on my chopper,and it performed well.but the bike was lighter than this tho. Any thoughts on this engine? are performance parts available?

 

[smgs92]

a robin subaru is definitely not a clone depending on how you look at it it's a much better engine than that.
the robin is the most reliable engine i have ever had minus my briggs flathead that will not die.
they're extremely reliable, very low maintenance, fast engines, good quality however if you want anything more than an exhaust air intake and rejet they're not very good cause there is no aftermarket available. it's a shame they're great engines stock for stock i'd choose a robin over a true honda.

Wait up, your first post said "dump the engine & go buy a new one" & now you're saying "don't ever get rid of that engine"; make up your mind...

The engine runs fine just the ususl external hackedup things. The swingarm has some questionable welds. And the axle has a 1/2" drilled through it th anchor the hub? Where can i get a new axle?

I assumed it was the stock tecumseh engine. If it was I would advise him to but after finding out it's a good quality engine that can produce decent power I suggest that he keep it.

Thanks for the info guys.

Ok, we get it, YOU don't like Tecumseh engines, that alone doesn't mean they're rubbish, that's only YOUR OPINION! Others swear by them.

Personally, I have no experience with either Tecumseh or Subaru Robin so, I can't really comment but, based on the fact that ALL Subaru car engines are made by Volkswagen, how good can the Robin engine really be?

Minichoper: Sorry to go off topic but, I felt it had to be said...

 

[minichoper]

No worries, i enjoy to hear everyones opinion. Then i take my experience , mix them together and see what makes sence.

 

[smgs92]

I've tried 4 tecumsehs in total all of them 6-6.5hp 2 were purchased brand new separate occasions from separate venders the other 2 came with the karts. 3 lost compression 1 of the brand new ones died on me after 4 months and i kept up with regular maintenance no mods. the other tecumseh had too many carb issues so i sold the engine for parts.

I've had 5 robins I have never had a single issue with any of them. I had 1 that sat a whole year outside bolted to a kart the engine started on the 1st pull. I can really beat up an engine the tecumseh couldn't handle it however the robin loved it. MUCH harder pulls on the same kart. Great engine design the only flaw is the lack of performance parts.
If you have no experience with a product why are you suggesting to people what to get or keep? That's like me going to a movie director and telling him how to direct the movie, I would have no idea what I am talking about.

Ok so, you've had bad experiences with Tecumseh & good experiences with Robin but, again, that's just your experience; others have had Tecumsehs that just won't die.

Personally, after everything I've read about them, I wouldn't buy a Tecumseh either but, I would never tell someone to junk a good engine in favour of a potentially bad one or any engine for that matter: If it ain't broke, don't fix it.

Hey, I don't like Fords but I wouldn't tell someone to junk the Ford engine in their car/truck & replace it with a Chev or a Mopar. Effectively, that's what you're doing...

If you have no experience with a product why are you suggesting to people what to get or keep?

When exactly did I do that?

When it comes to engine trouble, unless we're talking about catastrophic failure, I will always suggest repairing it for two reasons:
1. Going out & just buying a new engine creates more unneccesary waste
2. The experience of rebuilding an engine is priceless.

Any moron can unbolt an engine & bolt another in it's place but, that feeling of total satisfaction when the engine you just rebuilt kicks to life is, again, priceless

EDIT: This is becoming borderline "political debate" disguised as a difference of opinion. The difference between you & me is I make unbiased suggestions while you are, IMO, trying to force your opinion onto others based on your experience & that's just not cool

 

[smgs92]

those people are lucky i could potentially believe if they're an older design perhaps older tecumseh's are better built but the ones I had were poorly designed and a clone engine was a much better choice.
He could've sold it instead of just junking it. Here's how I see it I would rather go out and buy a new engine and have peace of mind instead of rebuilding an engine in most cases unless i know it's going to be a good engine. A new engine is generally going to last longer and you can buy warranties which means more ride time less worry about having to repair it.
I prefer the feeling of building up an engine and feeling the power gain. It's easier working on a brand new engine obviously.

Sorry to the OP for hijacking this thread

This is a forum for this exact reason. Voicing your opinion,and hearing others.

Back in the day, Tecumseh were right up there with B&S & Honda, why else would there be sooo many of their engines on everything from lawn mowers to go karts but, there must be a good reason why they went out of business but B&S are still going strong.

I have no problem conceding that point but, without personal experience, I can't comment on how good or bad they are. My issue here is that the idea of this forum, like all others, is to provide unbiased help & advice to others based on our own knowledge & experience.

As a result of your personal experience, you now have the opinion that all Tecumseh engines are rubbish &, therefore, IMO, you can't provide an unbiased opinion on the subject.

Here's the problem:

Here's how I see it I would rather...

I prefer...

This thread isn't about you or me, it's about minichoper &, all things considered, what's best for him!

I'm not saying you're wrong or right, everyone is entitled to their opinion but, it seems, lately, everytime I see the word "Tecumseh," I see you posting "it's rubbish, get rid of it" or words to that effect; that, to me, isn't an unbiased opinion

This is a forum for this exact reason. Voicing your opinion,and hearing others.

I like the way you think

that chopper is beautiful.

Thanks, it was pretty cool
