G22 jets/filter

[rheller219]

looking to gain a little more power out of my g22. lifted with 23" tires. Has Plowmans clutch with orange spring in it, and govenor removed. Does jetting and air filter really give much of an increase? Just curious for opinions before calling Plowman for jets and a filter. Am I better off drilling out my jet and getting a cone filter? any insight and experiences would be helpful! Thanks!

No. If you've got the clutch, go back and get the rest of the performance kit. You won't be disappointed.

The performance kit does a couple of things for you. Most importantly, it allows for an increase in air/fuel at higher RPM (which, if you have the governor removed, you'll see), and prevents a potentially engine damaging lean out condition. It also gives the engine a little more power at the low end, for better acceleration.

While you could drill out your own jets, unless you know exactly how much to drill, it becomes more like a game of trial and error. Also, for a carb jet to properly atomize fuel, it needs a certain degree of chamfer, which gets partially removed as the hole in the jet is widened. The nice thing about Plowman's kit is that the jets are designed to work with the airbox mods and filter. There's very little guess work involved, and the air:fuel ratio is properly balanced.

Sandbagger hit the nail on the head:

In the performance kit, the primary clutch is machined. What did they machine?
What did they machine to make secondary clutch overdrive?
Any idea how big a jet comes in the kit?

They machine the lower mating surfaces so that the two halves fit closer together, forcing the belt to ride higher and creating lower initial gearing. The helix side has plenty of material there, so machining off a little does not cause a weak point.

Wouldbt running a wider belt achieve the same thing?

Let's say you did, you would also lose top end - so by machining the pully your cheating the low end while not harming the top end.

Exactly.
I purchase my clutches from Erlandson Tech and I am pretty sure Don and Tom do as well. If you take a look at their clutches and weight kits, you can see what is available from your pro shops. I use the severe duty Kevlar belt they manufacture as well.

For the Op- To answer your original question, the answer is yes and no. If your original jetting is correct, adding new jetting will not increase your power. If your original jetting is lean or you add an accessory such as a low restriction air filter or exhaust add on which creates a lean condition, then yes, larger jetting will increase your power.

just so every one knows, we do not use parts from any other co, we design and make all of are components!!!
