MY ZX50 O.E.M CARB TUNING

[art]

 Just to verify the the bel rey. The gal i got my 2005 ran it religiosly (synthetic) and when I pulled the pipe literaly balls of carbin the size of golf ball rolled out. Now the cylinder and all held up well for a 7500 mile motor. But I never had anything like this happen with yamalube!!!

[thebatman]

i will look into some of that yamalube stuff...heard of it, bout it...lmao

So is bel ray a low quality oil?

[art]

 I think it's a good quality oil but the carbin build up is weird. The way it was explained to me if you plan to take it down after every race it's a great oil(from my dirt bike days) And if you have a personal machanic to do this it is even better! But for a daily driver and a little neglect I don't think it suits the real world to well. Every bike i have run it in has done this and honestly it performs well but the carbin build up is insane. Like i said I've run yamalube and never had a build up like this after many hours of abuse.
  Ha! so it's a great quality oil if your in the competition end of the spectrum but high maintinance seems to be a must. I personaly realy liked this oil till i had to do a couple teardowns after using it. Carbin city. May have something to do with the pump gas couldn't run race fuel all the time.I don't know

What about oil for 4 stroke engines.

  Ha! I'm not an expert    I like mobil 1 synthetic in the top of the class,but valvalien, havilien are realy good.  I used to like quaker state before penzoil bought them. I do not like penzoil for anything.

.. What about oil for 4 stroke engines ...

..used Castrol for a long while, until i switched to full synthetic...

..i use Royal Purple now...have been for a year...

[art]

 Yep forgot about castrol good stuff too. Royal purple not easy to get here so I've gone to mobil for convience.

[wordslinger]

...some good stuff!!..

[thebatman]

i definately had a bunch of carbon....still had that good noticeable difference today   id swear i just got 2-3mph on top.

[wordslinger]

..carbon indeed!!!

[thebatman]

yeah, i guess this is my last half bottle of the belray... that was robbing me badly on performance!....                           next ? i probably have already covered earlier..lmao... yeah art, that JUST OFF idle throttle is about dead.. from 0-13 dead/slow, then she starts getting there..much quicker, faster, higher top end, mid thru top seems great, just that begining..thinking rollers for part BUT part does seem to be carb....is this where our convo of shims comes into play???

[art]

Yep making one right now    Just try one but make two it's easyer that way.

[thebatman]

i assume that its a small circle, to fit inside under the needle..just stab the needle thru the can??.. or try and drill a hole with micro bits?.. sorry it took me so long to reply.

[art]

 Take a good look at your needle. Mine ramped up to a larger size. Cut a tab(beer can) fold and drill to the right size (use vise or vis-grip) . Than slip over needle and trim to fit. Try one to start but save the other just in case. Two made mine sputter.
