2.5 HP HF Performance Tips / Tricks

That would work too I bet

Wow, looks great SB. You do nice work.

I did the "get-er-done" thing and went with a hole saw.

You're welcome. I don't know that it looks great, but it works. I don't see why you couldn't just drill a bunch of holes in the plastic cover and get the same effect.

Like this one for one of my HS ? Strategically placed holes for that swiss cheese effect LOL.



Now it just needs the UNI high-flow green filter that AGK sells for both the HF and HS stock air boxes.

I did the Dan thing on mine, used a piece of hardware cloth or chicken wire as Dan called it for a cover. Don't look too good but works great like the rest of my bike.

The stock air filter boxes are pretty restrictive. It's neat to see the different approaches you guys are taking on opening them up. This is so fun! I love modifying these little engines for better performance.

I love the "Elmo way" Gets it done with no fuss. Really, look up his work. Simple and works. Well worth the read.

Elmo, I lost the pics of the hardware cloth cover. Post one?

 

[Dan]

Bad pic of the "chiken' wire"

 

[Elmo]

O.K. Dan here is a picture of mine.

Now I gotta go find mine or make another one, Elmo. "Summer Cover"

After hearing how some guys with the 6.5hp greyhound are getting a stronger con rod after removing the governor, I'm worried. Will our 2.5's grenade a rod through the side?

 

[Elmo]

I have 2000 miles on mine and have ran it 6000 rpm many times and it is running like new. The 2.5 seems to be very strong. I haven't heard of one that came apart.

 

[LS614]

Yeah, I was wondering, I don't know if anyone has had a look inside the case, but I wonder if the rod is iron? That would change a lot.... Anyway, glad to hear it Elmo! Mine hasn't even been run yet, but will be soon enough

 

[Elmo]

I have not been into mine but from the pictures others have posted it is aluminum. AFIK all small engines produced today use aluminum rods.
