Banshee-swapped Honda Grom

sweet jeezus…

Back in the 80's I bought a YSR 50 and swapped a built YZ 80 motor in it. The thing was crazy and it was hard to keep the front tire on the ground.

 

[rrrr]

I noticed he backed outta the throttle when the 99 MPH death wobble started. LOL!

I like it!!

That thing has so many things wrong. To start, it sounds like it's going to self destruct at any moment, entirely too lean, engine is hating life. And he will be replacing that tranny again with the angle he has that engine mounted. It will never oil the tranny correctly.

But I give him props for doing something different!

I like it.
I love those 2smoke motors

Guy I know built this years ago the Grom just reminded me of it

If that’s wrong, I don’t wanna be right

 

[JUSTWANNARACE]

The "things wrong" can be corrected in the right hands. Biggest things its lean as hell and its gonna keep eating trannies.

Dont get me wrong, I'd throw a leg over it!

They started as a motorcycle so why not!

I never put 2 + 2 together…I had no idea they were the same engines

 

[spectra3279]

I always loved the old rz350

 

[Boatymcboatface]

The thing that killed that bike was it wasn’t available in California lots of guys would use the 7500 mile loop hole to bring them in but it was a pain. I used to look through the green sheet and cycle trader magazines at 7-Eleven hoping to score a deal on one that had been plated when I was a kid!

 

[rivermobster]

Awesome!!!

Dude has some talent. So fun!

I built the engine in this one for a guy in the UK, 64mm stroke 76mm bore cheetah 580cc(banshee engine) in an Aprilla!

That’s AWSOME. What type of fuel did it need. Also how much HP. Always wanted to do something like that. I had an RGV 250SP withe the factory dry clutch ect. Sent the motor to England and had Stan stevens do his 300 kit. Made a nice 72 at the rear wheel.

@JUSTWANNARACE how hard would it be to build a banshee shifter cart?

I had a '87 YSR50 and wished could have had a YZ80 engine in it. I did ride that thing from the San Fernando Valley to Long Beach airport one day.

It was around 120hp on pump gas

Not super hard actually it's just time and $. As long as you have a welder and some skills..

How fast would something like this go?

You'd be the first one to the scene of the crash

I mean I have cousin who is a welder and another cousin who is a mechanical engineer I am sure we could make it safe for me to strap my ass into

 

[77charger]

a friend I jet ski with out a striker banshee into this Honda this is very fast.

They've got the ultimate set tools dude. Relax.

Mine was also an 87. I would cruise the beach on it all the time but it was pretty slow with the 50cc motor. The YZ 80 motor surprisingly bolted right in. Having a pipe made was the only tricky part. It was pretty crazy with power and a super short wheelbase.

YZ80 was a badass

Makes me want one for cruising around the neighborhood.

And beat the EMT’s to the scene by a good 20 minutes

 

[pronstar]

I guess this is the next logical step…turbo Busa motor, 600hp but turned down to 300 because it was undrivable.

 

[BIGRED9158]

We are going too start small and go up in size with the motor we are starting with a 125 Honda 2 stroke Motor should be a fun process one cousin is a welder other cousin is a mechanical engineer and builds drifts cars on the sides

Their dad must be a "TV repairman"?

A couple of buddies and I, @n2otoofast4u being one of them, ran karts for fun/hobby for a few years. I had a 125cc Rotax Max and a CR 125cc shifter both in SKM chassis. They looked identical. You will be surprised what the 125cc can do when set up right! They are a blast. We spent more time running each other off the track then anything good times!

My Rotax.
My CR125 shifter looked identical same chassis colors and everything, except it had a clutch behind the wheel and a shifter.

Well maybe we will do a 250r motor how did your 125 run for speed

The shifter would pull 80mph(gps) on the straights.


This is my other buddy that ran with @n2otoofast4u and I.

Do you think I can get into the 100mph with a 250 motor

 

[badgas]

OMG

99 on grom Never ever

 

[MK1MOD0]

In Eupore they run the 250 cc super Kart class. Here is a screen shot from a site that build them: Some guys are running TZ 250 motors.

I thought 125 shifter carts would go that fast. Depending on gearing of coarse. Always wanted a shifter cart to play with.

Well shit I might break the speed record with a banshee motor

Like @bonesfab said it's all in the set up. I know my 125 shifter could have done 110+ with more gear. But all we have is short coarses near me unless I went to PIR. So mine was geared to the track we would run.

Go for it. There's nothing better than a high revving two stroke on the pipe to make neighbors appreciate you.

 

[caribbean20]

Before I die, I want to go for a ride in a shifter cart. Always been on my wish list.
