Who Wants To Go 50mph on Friction Drive?

[Deleted Member 4613]

Here's how to do it:
Buy a FD drive with a 1.5 inch roller.
Buy a Zenoah G430 2 stroke with a 12,000 rpm max
Here's the estimated speed:
12000 x 6.78 x 60 all divided by 5280 = 53.3 mph
26/1.5

So who is brave enough to do it?

Paypal me the money for the stuff, and I'll even record it! Lol!

We need a brave soul with money.
Where is this hero? The Stanton drive
engine combo is close but needs a
1.5 inch roller.

A CY460 4.5hp engine on friction drive can reach 45mph.

Ask me how I know this.

Really, Your Idea you build it. I'll be the and ride it.

OK, you know your dying to tell us, so go ahead and tell us But I bet it has something to do with 4 1/2 HP

Do you have a video of the CY460/FD at 45mph?
It tops out at 11,000 rpm, whereas the G430 tops
out at 12,000 rpm. Zenoah routinely makes high
rpm 2 stroke engines for the rc market, and are very
popular with rc pilots.

LOL, nah.

It happened 10 years ago.
I had just gotten the used 460 from a member here, when I put it on F/D.

Wrench, you know that stretch of Farrington Hwy from Pearl City to Waipahu?

Over there.

The 460 never liked friction drive.

When it acted up, it would scoop a divot, nearly every inch of the tire's circumference!

ANNND, the 460 was a dog on steep hills, once it dropped below its power range.

So I installed the 460 on a shift kit.

And it just LOVED! the gears.

My buddy did 50mph+ on Kalanianaole Hwy by the Women's jail, with the 460 and Staton rear chain drive.

I like 35mph.

It sounds like you are afraid of speed, @Deleted Member 4613 . I've been to 53 mph and it wasn't that bad with my setup. It felt like it was fine to 60+ mph, but my engine (hs144f) couldn't pull harder.
Your engine setup might be able to spool to 12k rpm, but does it have the torque to push against the wind to 53 mph? How much of a dog will it be on takeoff and uphill?
I think you should do this test yourself, or look up others trying the same thing. Don't ask someone else to be crash dummy #5 to see if the same thing happens with the same setup expecting different results. You do it.
