Default New Revised V Spec...

Hi I just got a new V spec and have noticed it has a revised carby.
I don't know what else is different and wondering how long has this revised version has been out.. I think the running in is different according to the instructions as well.

The revised carby is a 21 J as the older version is the 21 C.
The main difference being that it is all one piece.
The 21 J has a pressed fitting for the fuel inlet. The idle screw is different as well.
I have herd that old version break off the inlet side of the carby when you re postioned the fuel nipple. Due to the press fit. I think that is all they did to it. I will be replacing the bearings as I don't trust them.

if you have the newest vspec then you have the updated case also. The newer case solved the bearing issues that vspecs had.
I would just do bearings somewhere 2-4 gal mark. imo

damn, just checked my v-spec and its a 21C. I had it order from USA and rcplanet had to order it from OS Speed so they must have sent an older one. This is only 2-3 weeks ago...

Gee I bought mine from here in Australia. Us get the newer version that MUST be a first here as we only get the older stuff.

We are a piss in the ocean compared to the rest of the world. Lucky me..

Hi Guys,

The lastest OS v-spec 2008 come with the 20H carb, which is the same one on the Speed. The crankcase and bearing have been updated in the 2007 version. The new crank had an extra rib outside the carnk near the rear bearing and new bearing have 9 balls.

Sorry don't have my cammera here. The block is different too and you can really see it when compared to a older version.

I bought a v spec when they first came out and on its 8 ltr it blew the block out under the con rod the seize of your small finger nail. It was sent back to OS in Japan and i was told it was my fault. They clamied that it sucked some dirt in. Sold the piston and liner and is still going . Gee i must have dusted it bad.

Good to see they have done somthing about it. The V Spec to me is one of the best or the best club racing motors out. Good to see a slightly better version...

I feel your pain . It took me 2 yrs to return back to a OS.
I really look after my equipment and to be told that when i could prove that there was no dirt and good fuel/oil used is just bullshit.

Well they do have a good product so I just had to get over I lost a weeks wage. That is why my current V spec has better bearings from new. I have done about 10 ltrs on it know so I thought I should replace the rod.

I have just bought a new V spec and noticed the changes. Im sill going to replace the bearings as I dont trust OS quality with them.
