Sounds alright for a stock cammed 5 hp. Put the airfilter on. I find the OHV engines have a more throatier sound though.

 

[modelengineer]

NEEDS AIRFILTER!

The engine sounds awesome btw.

 

[BradenM]

Excellent job!

 

[jr dragster T]

I think if you realy wanted it to have more bite like a nice crackling idle like most people love, I think you should raise the compression and throw in a good cam if you can.

 

[STreetKArt]

how to raise the compression??

 

[robin]

atack the cilenderhead with sandpaper lol

There is a correct way which is well known.
Unless engine tolerances are thought to be bogus, sandpaper or filing is a definite no-no.

You dont want compression in a flathead motor, its all about the flow.

 

[Russ2251]

If over milled...then yes. Eliminating gasket is not enough to do anything to flow.

Huh? Theres a reason why my Rhino has huge port's and over 12:1 compression.

 

[Russ2251]

I'd be happy with 8 or 9:1 with an otherwise stock engine.

 

[Kenny_McCormic]

What I mean is flow>compression.

you run meth also your engin is not very powerful for its cc

 

[jr dragster T]

your engin is not very powerful for its cc

Are you kidding me?

60 hp from 400 cc is not alot a vfr 400 standard puts out 54hp
and you could get the hole bike for half the price of your engine

my kx 85 had 28 hp at the crank

aprila rs125s have 33hp standard

and many more...

thes all run on pump gas and reliabul and cheep to maintain
your engine is based around a b&s flathead engine witch is made made to be cheep and wont break easy

you polish a turd its still a turd

 

[Kenny_McCormic]

Calling the flathead design a turd removes any validity from your argument. There are ford flatheads in model Ts form the 20s that are still going today, many probably on standard size parts, same goes for the old briggs engines. The flathead design tends to last FOREVER if cared for and decades when abused.

Might as well compare a nuclear sub to rowboat.
Pretty impressive stuff coming out of Tyler's track burner based on what i have seen of it.

flat heads are cheep and reliable thay are not for making serious hp

i do think that his drag star is quite impressive that it can make 60hp from a flathead 400

but think how much more power you could get if you put as much money into something with more potential to start of with

Wheres the challenge in that?
