What handlebars will fit an 064? Will 440/460 wrap bars fit?

Here are two with new factory wrap bars on them. I think with the old 3/4 wrap you need the special brake handle. With the new wrap one you dont. One is Glock37's the other is Randys.

I'm just playing with a regular ole 44 jug right now.

Nice work Doc !
Lots of porosity in that intake runner .............. did you weld it up or JB it after grinding ?

Thats only the roof.

The floor (where most of the flow happens) is 100 grit smooth.

I didnt want to catch the plating with a sanding drum. Don't want the roof any higher (rings at BDC)

It's not done. I still have to chamfer and get OCD on it.

The old style stock 064 wrap handle will not fit with a non-wrap brake handle. I've been told that the 3/4 wrap off the newer 660s have more angle, and will work fine. That must be what's on the one in Dan's pics.

Here's a pic showing the difference in angle between the half wrap (on the left, that I modified into a 3/4 wrap), and the factory 064 3/4 wrap (on the right). You can see why the stock wrap needs a different brake handle...


Keith, 044/46 handle will definitely not work on an 064. They are quite different...


Another pic of my handle...

Clint you are correct! Thats what I couldnt remember. I know thats what Mike has on his in the pic. Not sure what Randy has but probably the same.

I installed the bearings last night. PTO side won't hold a bearing. Loose fit.
I can pull it out by hand with a cold case.
I had to use scotchbrite pads to clean the powder out of the bearing pockets so that didn't help any I'm sure.
Gonna try Loctite 620 high temp retaining compound.
I've used 609 (non-high temp) retaining compound and it is some tough ****. Has 3000psi tensile strength. The 620 should be good for 3500psi at up to 450*f

Devcon or Bellzona will work but may not be good for the next bearing change

Weld it... screw the races up n' everthing...

My 046 has them in the last cylinder I out on it and mill with it. If I pull it apart any time soon I'll look at the rings where they cross the fingers.

Fingers and bridges?

Do you feel that the bridges add much with fingers?

Whats up doc?

woulda been a good time to do just bridges then add the fingers and try it both ways? Or ran it ported without then go back in and add each?

Soup? Or as a pet?

I like both.

 

[Mastermind]

Stew actually.

They make a damn fine stew

With Heineken.

Everything is better with Heineken. (Except for my port work)

Im beginning to see alot of going overboard on the porting and that less can be more. Work off what the factory give you works out pretty good

Ok sounds good. So when the motor reciprocates and draws air through the carb throat and hits the venturi causes a pressure drop and pulls fuel in through the main nozzle? What happens if the check valve is bad ? Reverse flow? Is there a way to check the check valve in the main nozzle?

You can take a couple feet of fuel line and hold one end up to the high jet hole with the jet screw removed to check pressure. You have to use a finger to plug the inlet hole while you hold the line up to the jet screw hole as you blow into it. The inlet hole is the tiny hole that aligns with the tip of the high screw when seated. It should let air pass through but check shut if you try to draw air back. Carbs with the rubber check valve will hold pressure and should. Other carbs will have a screen and they're not meant to hold pressure, but just slow the backwards flow.
Some carbs have a flat enough surface at the inlet hole to allow testing without removing the high screw

What handlebars will fit an 064? Will 440/460 wrap bars fit?

The only 066 bars that fit the 064 are the early model 066. Later 066/660 are taller by about a full inch.
