Well, my wonderful wife has blessed me with a brand new Mugen MTX-3. It's not the Prospect, but she got a HECK of a deal on it, compliments of E-bay!!!

I am looking at a motor for it, I am not going high end right now, trying to keep my costs down.

I am considering the OS motor, but don't know what the difference is between:

O.S. .12 TR w/10J Slide-Valve Carb
or the
O.S. .12 TR (P) w/10J Slide-Valve Carb

What does the (P) denote?

Also, what are some of the first Hop Ups to consider?

Elmar,

You gotta do the front universals. The upgraded brake is a must and the titanium middle shaft helps.

Thanks

Hello guys...

I was taking a look at the Serpent Website and regarding clutch adjustments they say that the clutch housing should have minimal play, acquired but putting some shims between the bearing and the spring collar..

But I didn't see any Mugen guy playing with this endplay in mugen clutches. Assuming that both clutches are supposingly equal, if not, very similar, what this adjustment would bring?

Have you guys tryed this in our mugen clutches?

cheers...

i run my clutch with around 1mm of shims between the bearing and spring collar and then shim the bell to have just enough movement to spin freely this method allows for consistant clutch engagement as it is in a set position and does not rely on the bell sliding in and out which can be different depending on whether it moves freely every time,give it a try you wont be dissapointed:nod:

Re: shifting point
 
if you want your 2 speed to shift a bit later then just simply tighten both set screws, 1/4 turn a time until it shifts to your liking..

He recommends going with a B block and tells under what circumstances to change to the A or C. Grab one issue, it helps in other areas of the car also. Great to have in the Tool box when out at the track working on setup...
any chance of some one scanning it and emailing it to me? can not get it in the UK
thanks

Careful......the set-screws set the clearance of the clutch shoes to the 2-speed housing (See the manual for details).......they are different than the "Adjustment" screws.......

The 2-speed adjustment screws are the screws that do-NOT go straight in and hit the center of the shoes......(the screws that go straight-in are the set-screws).........To change the shift point.....adjust the OFF-centered screws that appear to be "angled" into the shoes......notice that the hole in the housing to adjust them is "angled" also....it should be clear.....(when you're on the right screw....and your wrench is locked-on and ready to tighten....the shaft of the wrench should NOT be pointed at the center of the assembly.)

Loosen both adjustment screws equally to make shifting earlier and tighten equally to make it later.

Not that I've had a problem with inconsistent engagement.....but this sounds like a great idea...simply have to change the way I measure the clearance.....can't measure it anymore, can you?

If you're adding the shims between the collar and bearing, where else are you adding shims to for the bell? Thats where I shim also(between bearing and collar) I thought that was how it was told in the instructions.

put shims between the clutch bell bearing abd crank nut until the bell does not drag when pushed towards the engine, then ad shims to the thrust race to adjust!

Hi guys,
Need a bit of help with the Kawahara solid axel adpter kit.
Basicaly I fit the adapter, the 16 touth pully and new shorter belt. Is this right?

Well basically the mesh is wrong somewhere. When I push the car along the ground the belt slips or clicks as if the one set of wheels is spinning faster than the other.

Am I missing a part of this conversion? Does anybody know what might be wrong?

Thanks
NeoRacer.

Which part do you shim first? Do you shim endplay then shim the inside where the spring collar and bearing meet? I have always had problems with my clutches not being consistent. Any help is appreciated.

Start from the inside with about 1mm washer I use a washer from oan old thrust race bearing its a good place to start.then shim so the clutch bell does not have much side ways movement but still spins freely.
if to tight will destroy the thrust race bearing.
