Default V-SPEC ???

O.S. Max .21 VZ-B V-Spec-T (P) HOW LONG HAS THIS V-SPEC BEEN AROUND? IS THERE AN OLD STYLE AND A NEW STYLE? IF SO WHEN DID THEY CHANGE AND WHAT'S THE DIFFERENCE?

the OS speed one isn't really all that special. the factory port mods aren't that great. and for the price, there isn't a gain worth justifying to pay the extra cost.

the original v-spec hasn't changed except they upgraded the bearings in all of the new ones because the old ones didn't last as long as they should have. So If you have one over a year old, it might have the old bearings in it!

and as for the OS speed version that's just insane, and personally I think it's a waste of money, because I've seen people with regular v-specs kick the crap out of the people who had the OS speed v-spec.

For the money, the power and the gas mileage, nothing beats the original V-spec.

I'll cry the day they discontinue this motor!

Well, OS had a HUGE problem with their newer engines, the vspec and TZ series were hurting. I dont remember if it was a problem with tolerances or if there was just a mess up during the assembly of the mills, but they did not live to 3 gallons.

By the looks of it now, and after reading updated reviews, it seems to be doing pretty well... when it first came out, it received HORRIBLE reviews in the mags because 2 of em failed prematurely lol.

ive had 2 vspec. the first lost pinch after 1.5. put piston sleeve and bearings lost pinch after 2-3 gallons. third piston and sleeve bearings con rod lost pinch after 2 gallons. motor temps never over 240.a year later lhs didnt have any other motors bought a second one lost pinch after 2 gallons put piston sleeve bearings con rod now have 10+ gallons on it. motor still has lots of pinch every now and then it will get cauch on tdc. engine runs better at 240-260 that at 210-230. ive got a novarissi , rb ws7 c6, radical all with 5+ gallons on each and still run like new. i bought a os vg same thing 2 gallons lost pinch sent it in and they replaced it for free. i still havent put any fuel thru it. im afraid it will loss pinch. guess a 140 dollar paper weight. just like all the pistns and sleeve ive bought. just what i have seen. jeremy

the vspec has awsome power and speed for the first few gallons...the other weekend i raced a club race and a guy had one that was only a half gallon in and i had a heck of a time keeping up with him on the straight aways, but in the tight areas of the track he couldnt keep up with my P5X...however i didnt save to much money on the navarossi engine, but i have 3 gallons through it and it is still running like new, and has lots of pinch (gets stuck at TDC sometimes).....
