twin disscussion

[Rotore]

Good thinking we NEED more twins!

 

[Rickracer]

Naaah, we need more bike motors,

 

[Rotore]

How about twin bike engines?

 

[modelengineer]

How much do all your engines weigh? I'd put mine on the scales but it's attached to the buggy and I don't want to remove it again.

How about who's got the heaviest engine? (I think I've got this one in the bag, I can hardly lift that one)

Rotor prolly got the heaviest, my kz400 engine is pretty heavy, but my 18 twin is equal if not heavier, so i cant imagine how heavy his 25hp kohler is.

How bout who has the most horses in their twin? i think it would prolly go

Tyler
You
Me
Rotor

 

[freakboy]

Hey what bout me man!!! i got over 200!!!!

 

[Rickracer]

I got a single with more than most of your twins,
How 'bout this twin?

Yea your Rm prolly has more power than my KZ, hopefully once i get a better carb/airfilters i can get a little more power, its 36 horse stock, maybe i can make 38 or so? either way its more than enough.

What kinda power will that RD350 put out?

 

[modelengineer]

Looks to be either 47hp or 63hp, depending on the year.

 

[Kaptain Krunch]

Nice, that would rip in a little racing kart frame. I bet it would make even more with some expansion chambers.

 

[Rotore]

My kohler is 127lbs kaptain i think your engine wins in weight but tyler probably has the most power.

*Most* lol. Whats the HP rating on the RM250 motor?

 

[modelengineer]

Tyler I didn't know you had a twin...

What year is the RM250?

I reckon mine is around 60kg, or 130lbs

 

[Rotore]

You guys with bike engines over 150cc will be heavier then my kohler.

My kohler is heavy because of the flywheel and starter other then that it's a light weight

Post #228 12th page. Also go into the photo gallery and project log and look at my Arctic Cat sled.

My Rm 250 motor is an 84, factory rated 40 hp @ 8000 rpms. It's got a bit more compression, carbon fiber reeds, and a better air intake system, so it's probably at least 42~43 hp, maybe more, and I know it will turn at least 9600 rpms, . It's actually a bit lighter than my Honda GX240 (maybe 5 lbs less, both are right in the 50 lb range), but if you add in the radiator, coolant, coil, CDI unit, expansion chamber and silencer, it may be 10 ~15 lbs heavier, still not a porker by any means though,

On topic: I would love to see a two twin kart. like a minisprint maybe, that would be some massive torque.

offtopic: rick, I see your paying alot of attention to this thread, and I got questions for you on mine lol. no worries.

 

[Rickracer]

I just happened to be sitting here at my desk as the email notifications are coming in,

 

[modelengineer]

Ah yeh, I forgot about the arctic cat for a sec.

Naa, a 250 will be lighter than yours, my KZ is prolly in the 120-135 range with oil.
