Hello everyone! Im new and could really use alittle help lol

[anickode]

Ohh ok i see what your saying i been watching videos the last 2 hours to lol so if i just get that clone torque converter that would replace the clutch and the 36 tooth sprocket and with just adding that you think i could hit 60 ??

If you built the motor and removed the governor, possibly.

Build the motor and leave the governor might get you just north of 40.

Stock motor probably wouldn't have the balls to get it to 45, except maybe on a very long flat straightaway, and your tires inflated good an stiff.

 

[Whitetrashrocker]

Definitely.

And if i just take the governor out and put a torque converter on it would i have to do anything else? I was watching some videos that said if u take out the governor i have to replace other parts? Is that true or am i good just taking it out and outtin on the torque converter? Thanks again for all the help guys!!

If you take the governor out or disable it, or even better, adjust the governor for a higher RPM... I digress.

The engine without a governor and no other engine mods installed has its own 'fail safe' so to speak called valve flutter. It's a point where the engine cannot run any faster nor can the valves close and open fast enough (hence they "flutter") for the increased RPM. It has a characteristic sound too, so you'll know it and feel it when the engine sort of hits an intangible brick wall.

However I think we collectively need to readdress the governor adjustment scenario. It's not just 3600 revs and you have to live with that factory setting....

No you're right. All those different holes where the rod and spring connect are the adjustment points. I got my rat kart motor to rev just shy of 5k simply by moving the rod and spring to different holes.

And what do u mean by build the motor? Like air intake and exhaust and torque converter? Anything else i would have to do to reach 40 without taking the governor out??

So if i just move a rod and spring i could get motor just shy of 5k? U know a video or pictures i could see to do that?

Sorry about all the questions lol but i see on ebay they have a torque converter for the predator engine for 99.99 bucks that comes with 2 sprockets and hardware. I also see other ones for like 63 bucks like the link says above.. But do u need the 2 sprockets with a torque converter? And should i just spend the few extra bucks or save some money and get the cheaper one? Again thanks for all the help guys!!

 

[anickode]

They come with multiple sprockets because it's easier to include a 35 and a 40/41 than it is to deal with customers who don't know what they need or ordered the wrong one.

You will need whichever sprocket matches your chain.

This talks about the 5k gov mod...

Not only that video ^^ but it has been hashed out fairly recently, in this thread, among others:

http://www.diygokarts.com/vb/showthread.php?t=35234

Outcrydrummer (Kart Art) sort of paved the way on that governor mod, showed us the light since he and others race engines with governors adjusted to allow 5K.

There is no difference between the $100 TC and the $60 TC except for $40. Unless you get a true Comet torque converter, they are all Chinese knockoffs, probably made in the same factory. There are much better ways to spend that extra $40

Do you know what size chain you are running now?
It looks like 1/2", if so the sprocket in the kit is the 10T.

If it were me and you are currently using 1/2" chain, I'd get the TC and also get a 5/8" 8T #41 jackshaft sprocket. That would give you 6.75:1 and 6.075 : 1 with the TC overdrive.

Your tires give you 4.71' per axle revolution.

Mod the governor to allow 5k RPM.

(((5000 / 6.075) * 4.71) * 60) / 5280 = 44mph

If your engine cant pull the buggy with 18" tires to 5k RPM, then try the standard upgrades... Air Filter Adapter, Air Filter, Exhaust, Carb Jets, Advanced Timing Key. People claim 10 HP with these upgrades.

Garyslow,

Adding those examples^^ is what we call "building" an engine. It's a re-build with advanced and more durable parts usually.

Hence a built engine is the final result.

Adjusting that governor is about the single best (cheapest and low-effort) thing you can do as it frees up the engine to give you more much-needed revs.

Ok i think i measured the chain right its pin to pin right? If so it is a half inch chain thanks for your patience and help guys i really want to get this going better but have very limited experience with anything like this which im sure u can tell! Lol and that 8th # 41 sprocket would replace this sprocket in the second picture?

 

[Garyquick]

And i watched that video and looked at my spring placement and its already the same placement as the video says? Ill read thru that thread that its discussed

And im looking for that 5/8 8th #41 jackshaft sprocket but only comong across 9th or 10 th?

 

[Garyquick]

And l tgis torque converter comes with the 10 th u were talking about and the 12th its only 66 bucks but the 60 dollar one only came with the 12 th sprocket so i think I'll get this one and its still 3p bucks cheaper lol but what you think of what it comes with? Everything look good for what i need?

 

[Garyquick]

And i been looking around to find what the 2nd chain is on my go kart? I have the 1 on the jackshaft and the clutch and another 1 on the othwr side of the motor? Is it just to turn the other wheel? I see alot of go karts with only 1 chain thats im asking

 

[Whitetrashrocker]

Engine turns the jackshaft with one,and the other transfers power from the jack shaft to the axle.

 

[Garyquick]

Ok i see im out in my garage playing with it thanks! And sorry for all the questions which im sure are really stupid to some of u guys but i just want to make sure i do thia right lol any imput on the othwr questions? Im about to buy the torque converter just want to see what u guys think about that q and what u get with it? Lol and also when im driving my kart it seems to be "jerking" alot .. Ill be going and then itll will stop my acceleration and slow me down but im only going about 8 to 12 mph at that point? Is that the bigger sprocket? Like always thabk you guys sooo much u dont even understand!

 

[Whitetrashrocker]

Try putting the rear up on blocks and hand turning the tires. Everything should spin freely. See if your binding issue is there. While your doing this you can also check the brakes. Do they want to bind? They should operate smoothly.
While you have the blocks out check the front tires too. Again free spinning is key.
