twin disscussion

[Kaptain Krunch]

Rods dont determine stroke, cranks do. That rod will give you higher compression, but it will not increase stroke at all.

that was a duh on my part!

lol good thanks guys

The longer rod will just increase the piston pop up. Measure how much its in the hole and how much room you have to work with first.

 

[BriggsTwins]

just millthe head!

 

[freakboy]

you dont want it popin out father then it should dude not good.

The piston is 2mm away from the head at TDC. ANd as of now it does kinda touch the head but it wont after i get all that carbon of the heads.

so would it be safe to go with a .010 longer connecting rod or should i just go with the standard size?

 

[freakboy]

a .010 should be alright but you can shave the piston a bit like .05 so you get a lighter piston. just make sure the first pison ring dont come anywere closer to the deck then 1/32

 

[Rotore]

will do!

 

[freakboy]

what cubic inch is that engine?

 

[jr dragster T]

If it where me I would be getting the standered sized connecting rods. You want to measure piston top to deck height with a dial indicator or something equivalent. Remember changing the rod length and nothing else affects the thrust side geometry. Just something to think about...

what cubic inch is that engine?

its a 44 cubic inch v twin dude here are the specs on it

your right i should just get it running at factory specs first and then mod it.

 

[BriggsTwins]

so who is putting their twin on what....or already put on

 

[modelengineer]

I'd mill the head or mill the deck, rather than buy a .010 longer rod.

 

[Rickracer]

A longer rod (with a piston that has the correct deck height), will be easier on the piston and make more power. IDK if .01 longer would help much though, probably not worth the trouble unless the plan is just a stronger rod, but the piston MUST match, or it will stick out of the block.

Well my kohler is poop i cleaned the block to inspect it and found huge cracks and chips in so cant its trash will be takind off the carb, starter, oil cooler, coils and fuel pump and through it on a 18hp kohler opposed...

hmm, I'm not sure wether to put my briggs V on a single seat kart or a reverse trike like Irenaat made. his was basically a reverse trike racing kart lol.

 

[BriggsTwins]

hmmmm
doesnt sosound too bad there. im kinda thinking a chopper maybe

go for the reverse trike dude its awsome!

hmmmm

again go for it

 

[kazkepox]

again go for it

I want to try and Find a racing kart and build up a reverse trike with that, if not I will just find a single seat kart
