Good morning !

Where can I get the biggest valves? And what is the price? In my first post, I had asked where I could download the H engine instruction manual. I have the one for the J engine on hand. The two seem very similar, but I don't know the difference. that would help me put it back together.

Thanks a lot in advance!

DUF, stay with the whizzer 7/8th valves. Your motor will have plenty of power.

If you decide to go bigger you'll need to go all the way....Bigger valves, bigger piston, webber cam,and some trick stuff.

Here's my H motor,

Heads been shaved all the way down, super small combustion chamber. Fred's big valves, webber cam, Mikuni vm18 carb cut down and lightning piston...knife conrod and crank.

Head, valves, piston,and jug have all been coated with a thermal barrier,(heat coating)

2 cents worth

The "H" has 3/4" valve's and a good upgrade would be 7/8" intake valve

Yes, some port work and she's good to go.

Best choice, beginners start at stage 1

At some point in their life even the Pros were beginners and started at Stage 1

So what happened to you then???...lol...lol...Your still on stage one???...lol.

Yep, That's what I tell people, Stock NE-5 with a few minor Upgrades

"Minor" in the eyes of the beholder! Nothing in your pursuit of Whizzer Perfection is Minor!!

WAIT!! There's still more. When I built that H motor, I also built this one for my buddy who lives in indiana.

this one has the bigger valves. A a Briggs & Stratton racing valve. Our frames are going to be the Luxembourg frames with the Martin Roadrunner front suspensions. This will be a fun project.
