Will putting a 5-port crankshaft in a 3-port, improve performance?

Yes...but distance between Japan and The Netherlands is greater than between Japan and PR....you would expect the shipping rates in the same ratio...

I also ordered two conrods, they were only $15 each.
The 5-port crankshaft was sold out, but I still don't know if that would increase performance...

Default Ceramic bearings..

Hi,

Ridder, are you radar on another forum ? ... must be

I was thinking also on ceramic bearings, how do you people find the Bocabearings, high premium ceramic, with extra seal ?

Learned on this forum that conrod is not really problem with this engine, but several people complain about leaking front bearing..

Yes, its me!

I ordered the ceramic bearings, and I will put them in after break-in, together with a new conrod.
But first the TZ has to get here...

Has anyone done this? I ordered a 5-port crank and plan on trying it. I already have a new p/s & rod that I was going to replace and thought what the heck..

Yes, I believe someone already said that putting the 5-port crankshaft will increase performance due to being a little bigger.

So how is this engine? I have been out of the game for a while and this was the newest engine to have all the hype.

Easiest engine to tune and best engine for the average club racer.

I noticed you had problems from a previous post. What is this engine comparable to with other brands?

I have come to the conclusions that it was my fault the engine died on me. For one, I kinda rushed in the break-in process which is a no-no. I also ran a couple of races (2 to be exact) with a stripped 2nd gear. I checked the turns on my high-speed needle and found out that its at 2 turns instead of 3-4 turns. Friend of mine also commented that I shouldve changed the conrod after break-in since the TZ has so much pinch it really stresses out the conrod. I have raced Mugen X-12, RB V12 Rody, Mega Picco ZX12 and Rossi R12's and so far this is the easiest engine to tune and keep its tune throughout the different tracks of the island. When it comes to power, it can easily hang with any of those big boys. My lap times have improved very much when I bought this engine plus the MTX-4.

Best thing is, you will not find any other engine that has spare parts as cheap as the OS TZ and as accessible. To paint a mental picture, I purchased 3 conrods, crankcase and piston pin for less than $85 (after towerhobbies discount).

And incase your wondering 2 conrods will be replacing my TZ that on its way and the TZ that i'll be rebuilding after break-in. Plus a spare one.

O.S. SPEED MOTOR:

Scheduled release date for the U.S market: The end of May ( Tentatively ). I just talked to a major distributor here in the states that cater to mostly all hobbyshops that sells O.S. products and she said end of May, possiblly earlier .
