Engine advise: Sell kt100?

[Magice]

I was thinking about the rebuild costs of the kt100 and was thinking, should I sell the kt100 on ebay with my 300 dollar clutch and try to pick up 400 - 600 dollars for it?

Because I was thinking of using the returns and buying a 125cc ish 2stroke and making a shifter kart. They seem alot more practical and cheap.

Also, I can't decide if I should mount it and try it out before selling it!

Part out the clutch, probably make more that way.

 

[jr dragster T]

Yeah I would sell it. Its not practical for your average yard kart. And you already ordered the chain and sprocket might as well test it out. How is the engine started?

 

[Jerryburger]

H_LL NO! I wouldn't sell it! You have something that occupies the same space as a small Briggs, but is PURPOSE-BUILT for kart racing! Shifter karts are cool, but rigging up the shifting, clutch, etc.... a bit over the top for me and my limited time/funds. Personally, that motor would be worth more to me if I got it for the price you did, than it would to sell it. That is one of the better KibbleKart motors out there. Sorry- that was my 2 cents.

 

[Magice]

Started via battery drill

I just heard these are horrible on funds.. they spin 14k on the road, 18k free.. very bad rebuilds.

 

[kibble]

How about you let me have it? Buy it off you for $90. These kind of thing depreciate over time, you know?

 

[Russ2251]

Ebay would fetch the most. Not Craigslist.

Aw, but think of what you could be missing out on. Besides, ANY motor will need rebuilds if you run the %^&$# out of 'em constantly, like racers do. I'll bet for an average kart, one of these motors would be living in a lap of luxury if well taken care of. (Good oil, good air filter, proper jetting, sane right footwork)

100 hour rebuilds are for huge racing guys. You could probably go a year and do fine. With everything you've bought already, might as well stick with it.

 

[kibble]

If you sell that engine, I will be very upset with you! :toetap05:

I would NEVER be able to find something like that for that price around here!

 

[Kenny_McCormic]

sane right footwork

Where is the fun in that???

 

[Jerryburger]

Well, when your right foot is shoving so hard for too long on the gas pedal, that your wallet forms a huge vacuum... engulfing both buttcheeks into what can only be described as.....

"The Debt-Terror Pit of Death"...

(Clever use of "Terror" and "of Death")

I'm not saying be a FeatherFoot, but keep the finances in mind before ruining a good investment. That motor at that price is a nice find!

Carry wallet in front or cargo pocket, problem solved. Thats how I roll, only time I use mid throttle is to downshift the tav so it drifts better, but this is a mostly stock briggs flathead not a racing 2 stroke. Where in creation is the flywheel on this thing?

 

[Magice]

It came with a red restrictor. Do you think it would be a good idea to keep it on or to pop it off (would it save my revving but still allow decent speed)?

Also, I haven't actually been able to start it yet. I have to grind down allen key to fit my drill. I'll post a video first start! What kind of mixture should I use for this sucker?

Oh and here are some pix of the magneto and flywheel as requested...

I ripped it open (broke 2 allen keys, twisted 1), to find a little puddle of muddy, raunchy smelling water! The flywheel is SMALL!

First opened & clean.. The wire you see leads to a sensor un-attached that goes above the clutch.

closer view

compared to pop can

again

pop can not lined up but nice shot of the flywheel

crap that came out when I opened it is puddle.. The rest I wiped out.

inside of cover. the center piece is real weak.. I could probably fabricate a pullstart.
edit: it looks like it was puttied on with something, there's a good leak in it. That's how the brown liquid entered.

 

[kibble]

Holy crap-sauce that's a tiny flywheel! I bet that small wheel is the reason it's able to rev-up really quick.

[oscaryu1]

Hehe, wonder how many times it fires in 2 cycles?

 

[ed1380]

once per revolution. i hope that wasnt a serious question

Im for you keeping unless you can make a good profit and buy a bigger motor with that money. dirtbike motor would come w/ tranny and clutch.

 

[Jerryburger]

Your actual flywheels are inside the crankcase, as part of your crank-throws. MeThinks that wire hanging out is a kill switch lead... maybe?
As far as the oil mix goes, I googled it and I'm seeing between 20>1 and 16>1.....

I'll try to move the wallet to the front pocket, but common sense tells me if I break something, it'll still cost just as much!

 

[Magice]

The wire leads to a sensor that is mounted on the guard above the clutch. I believe it tells it when to fire.

 

[kibble]

It's a clutch explosion sensor! :biggrinjester:
