Repost from the 19th century.  And your right, we dont care.


Why the hell are you still here? Did we not make it clear nobody likes you?  You failed the noob post and are still posting up crap and cars that arent yours with no porn and no tech.

Here is the forum your looking for.

Did I count 7 valves per cylinder?

Did I count 7 valves per cylinder?

The middle arm and spring are for the injector to pressurize fuel.  3 intake 3 exhaust 1 injector.

Thought that it seemed a little imbalanced.

there is actually no intake valves eh, it's a 2 stroke, all valves on the outside of the injector are exhaust valves

Yes, it appears to be a picture form the construction of the Large Hadron Collider.

Holy shit!  We were just talking about this thing at work last week.  One of the guys there that is into MX was telling me that Honda had made an engine with oval shaped pistons.

Fascinating stuff.

They stop b/c of ring sealing issues.

Originally used for Superbikes 500cc class Honda never won higher than 3rd place with these.

That was in the '80's then they released a 100 model run of the NR 750 for street at $90k in 1990.

If I ever get the nerve to buy a bike I want this one used I've seen them for $12k before.

Wonder if this tech. will get revisited by Honda anytime soon?

I immediately started looking info up after I had a model number to work with.

I agree, it would be a cool bike to have.

Thats cause its an Longitudinal mounted unit.  Teh horizontal mounted ones are much better, but still 1.8t fail. 

That being said, teh 2.0t is a FAR better engine, and is VERY reliable believe it or not.

lol yes, I own one and will reference 10 VW techs who will disagree with your one, sir. The motor (in a vw) has very few problems, all of which are well documented and easily repaired.  Not calling your friend a liar or anything, just giving the big picture as it were.

Just so you know, in my mind anything that is "reliable" is anything that is aprox. 10X better than a 96-02 toyota camry or corolla.  So yes, the MK5's are quite reliable, and compared to the failure RSX type-S that I traded for it, has been well worth it.  If you want a full account of my experiences with these particular vehicles, feel free to pm me and I'll jump on the soap box lol.

Meh, don't really care that much.

I remember him saying that the latest version of the 2.0t is actually pretty solid, but the first ones were not.

The only VW that I still want at this point is VR6 powered anyway.

Heh.  No you dont. One of my boys just ditched his busted vr6 for a 1.8t.  If that tells you anything.  VRsux are dubber hype.  Not much more.
