Time to upgrade drive train on go kart. Was running 12 tooth clutch to 60 tooth sprocket. Will be upgrading to torque converter with 12 tooth drive and 48 tooth sprocket.

WORKED FOR ME! Go for it. You will go pretty quick just won't go very fast until you find the right camshaft suitable for your desires.
despite what they say it Takes more than just valve springs for a fine tune.
COOL! Twin engines! street-run video?

Relativity meet Freerunner!
Don't bother.
Don't bother.
Do you think that gear ratio will work. I know you have duel engines and small tyres, but that ratio is really high

I think it will.
I remember seeing that Kart spinning the tires and doing donuts and burnouts
at 5:1 with CCs. So in theory I think it will be just fine With TCs, @ 4:1. Probablys just not do burnouts from a stop. But well worth it for the new Top speed.

I cant wait for Sid to weigh in and tell us we are all nuts.

What size tires and sprocket in the pic? Guessing it's the 60T with 10 inch tires? Looks like the sprocket is resting on the ground.
Looks awesome!

So your go kart didn't have enough power and acceleration to begin with? XD
4:1 is nuts.. but that's a twin mill.. so it might just work...
each TC/engine pack only has to provide half the torque needed to propell that baby blue basket..
worth a try I'd say.

OK so during disassembly I noticed my clutch had 12 teeth and sprocket was a 60 tooth. So that should have been 1 to 5 ratio. I'm figuring with a torque converter the drive sprocket to pulley sprocket should be maybe 1 to 2 to begin with and st speed .93 over drive. Wouldn't that be close to 1 to 8 take off power and 1 to 3.73 final ratio? Feels like common core math, idk.

1 inch from ground. Actually it is resting on ground with low tire.What size tires and sprocket in the pic? Guessing it's the 60T with 10 inch tires? Looks like the sprocket is resting on the ground.

I'm thinking I have 18lbs valve springs right now. Might need 20, or 22. Like the can, can't remember which, but I have monstrous compression as it is now. Gets tiring replacing starter cords and a broken hand from recoil. I am thinking I have valve float at about 7800 rmp well I know I do. That my idea for over drive! Nice to meet you. I'll had to snoop your post soon.

No, I got a karting problem and admitting it is the first step. Ha, need for speed or maybe just a little dumb.

i was telling you guys that gear ratio really did work even with a clutch. Now you should believe me and not someone else whos name i wont mention.
---------- Post added at 11:16 AM ---------- Previous post was at 11:15 AM ----------
,and no wonder you guys think i'm crazy for wanting more speed and power. it looks even faster in 3rd person lol. i just wish i had a good camera to record with at the time to prove it earlier.

Don't read too much writing in the posts. i catch too much sht from other people from my ideas that most of it isnt worth reading. decent pics and vids though. made 2 threads.
Uhoh freerunner...
please don't put yourself on the same level as Tihm;
And just because he made his engine provide enough oomph doesn't mean that you're capable of doing the same!
And no, if I had to make a guess.. YOUR KART will never see the road speeding below;
Relativity's kart has a good chance though.
Mostly because, he's willing to try, and if it fails because of a too optimistic ratio setting, adjust that and be speeding along..
You however instead of correcting your mistakes
rather think about installing a flux compensator just to stick with your stupid ideas!
And that's what makes the biggest difference!
So do us all a favour and keep your terrible advice for yourself;
one day a kid strolls by and believes the BS you're posting and will be bitterly disappointed by the result you "promised"!

No kidding....Tihm has EARNED the respect of this forum by carefully and thoughtfully approaching modifications and sharing his knowledge with informative threads, videos , and posts.
He has asked for help along the way and done his homework. He has proven his prowess as not only a problem solver, but an excellent fabricator.
You...on the other hand...have chosen to play the fool...and pretty much alienated the whole forum from day one. Well, if it means so much to say: "I told you so"...there were MANY members that warned you early on...and you ignored us....Sooo...Told ya so!
EDIT: And I don't think Relativity needs any advice from you...he was doing quite well long before you joined.
Umm, NO... my/a gear ratio (4.5:1) and 16" wheels, will NOT work for a CC... atleast not more than a handful of times if that... that is unless you're pushing/spinning it w/ somewhere around a 15~20hp engine (TOTALLY different ball-game... and subject)!
Plz dont compare my abilities of doing things, the same as yours... especially when 'harmful' info is added... it's like putting vinegar in a milkshake!
I'll take the compliment, even though my participation amount has dwindled to next to nadda... for reasons known to those that it matters to
BTW Im the 'Tihm' of whom they speak of, Freerunner...
Sid Im tired of the dysentery, hearsay, portrayal of neglected adolescence, from others (NOT you), so no need for the "Uhoh..." nexttime... LMAO, Im done defending what I know, to others, that corrupt my knowledge... even though my use of the english language is annoying to say the least
... but what he says is true, MOST can't mill their head nor port/hone their cylinder which are 2 things (and afew other little tiny things) that I did to create atad more hp w/out much wear or adding $$$ parts to the engine (it'sonly running a stage 1 upgrade, stock springs... but creating 10hp vs the 8hp that stage 1 provides... if done properly). Ontop of that, my ENTIRE rig w/ me on it is only 300lbs w/ only 6" total of tire drag in the rear and about the same up front (on pavement)... I had more air drag than weight/traction drag
... I say 'had' cause Ive sold it recently ($700)... not sure if the guy could handle what he was buying... hasnt been returning my texts... hope he didnt wreck the kart... lol... ... but
I HONESTLY think Relativity can surpass my karts drive train abilities BIGTIME!!! (not that he hasnt alrdy!) And BTW Relativity ... your NOT getting valve floating if you are running 18lbs springs and a stock carb. "IF" you are running a stock carb... your mistaking fuel/air limits of the stock carb, for valve floating... need to upgrade to a 20mm Mikuni(sp?) aswell as up the spring tension to 20~22lbs, for more rpms. Some will disagree, BUT unless you get/have a highend cam, installed... adding rpms over 5k is obsolete, because of the power curve.
You are pretty much correct in your ratio math though! Due to the TC engaging at a MUCH higher torque#, ratio/gearing can be shifted to the speedend, due to the TC having a much wider ratio of torque.
Im pretty sure someone will have something to articulate against what Ive said... but nonetheless... my .02yen

Well, Tihm....your reasons are well known to me. That doesn't diminish in anyway the contributions and achievements during your more active time here. I'm sure many members have benefited from your help.
You still have the respect of senior members in the know. If you remember, I called you out on your claim of a 100 yard pellet gun...until you went into details of your modifications and components involved....and then Poboy just tucked tail...and waited for all that to pass...because you proved (to me...at least) ...that that was an honest claim.
You predicted expected results and met them with some kind of crazy Asian/Redneck engineering....
Good to see you at least spending a little time here. Still in the small engine repair and hows business?

How much to overnight gutted bullfrogs to White Settlement? But they have to be shot between the eyes...or you lose credibility on the 100 yard shots!
Yes...guys...you heard right...Tihm was head shooting bullfrogs at 100 yards with his old pellet gun...didn't you trade that for the basic kart you eventually built up to the one in the video....(I've slept since then! )
