That guy must be using Klotz oil too . actually, if that bike is as he says it is, that doesen't sound like the price is way off, considering the rarity of those bikes in this country. I'd offer $4K for it, but wouldn't go over $5k

I saw an RS50 the other day. Pulled over just to listen to him attck the on ramp. Rode home with wood.

Dont know if this is appropriate,but I have an rz 350 for sale, spec2 expansion chambers, other bolt ons, needs carbs,gastank,filters and/or airbox. 50+hp, <300lbs= fun. 2strokes rule.

In reply to HappyAndy: Not worth it, check walnecks,they are not that rare. For that money low mile,unrestored with no mods possibly. Old auction,what did it go for?

this is my new project a 70 suzuki t125, its gonna smoke again someday

Good luck! She looks pretty rough but throw enough money at it and it will look good as new.

Bump from the dead!

I just remembered another really cool bike from the 90's, the NSR MC28. I'm pretty sure it was one of the gray market Japanese imports, but it looks super nice.

ooooooooooo I would sell a kidney in a heart beat for that.

There is a small bike shop near me that has an NSR (it's been a while since I saw it so it might have been and Yamaha but I don't think so). Apparently the story is they brought it in from Canada in pieces and reassembled it. Based on their high-ish prices they probably want quite a bit for it but it is a beautiful bike and I bet it sounds great.

They also have some other interesting bikes such as a few RD350s, Triumphs, and a 50cc 2-stroke honda street bike for $1000 (might be an NSR50 http://www.youtube.com/watch?v=HdamapbUp6s)

I regularly see an Aprilia RS50 on campus. It's almost comical hearing such a tiny engine note out of a sport bike.

This guy looks like a blast:

this too, although pricey:

Seems to me there was a guy selling a green two-smoke on here a while ago....

Yep that was me

Okay, I just started reading the following thread, but it looks promising so far:

A disclaimer, a lot of members here have nsfw avatars/signatures.
TZ750 (750 cc 2-stroke!)

And here's a youtube clip for you impatient folk

1968 OSSA wildfire. Their first attempt at a 250cc gp bike. My mother has one sitting in her garage.

one of these? http://images.google.com/imgres?imgurl=http://motorbike-search-engine.co.uk/classic-bikes-2/1967-ossa.jpg&imgrefurl=http://motorbike-search-engine.co.uk/classic_bikes/ossa-classic-motorcycles.php&usg=__qb30dGhc3wGR0__7zvmDY1gr3kA=&h=600&w=800&sz=104&hl=en&start=6&um=1&tbnid=nH9Ex-q8oAmTDM:&tbnh=107&tbnw=143&prev=/images%3Fq%3D1968%2BOSSA%2Bwildfire.%26hl%3Den%26safe%3Doff%26sa%3DN%26um%3D1

supposedly there were only 670 produced.

Similar, there is a pic of one further down the page. Hers was a street legal version with a low pipe. but yeah. People that knew about Ossa's looked at it back in the day and said WTF is that.

Hello to all

"Stroke" refers to the movement of the piston in the engine. 2 Stroke means one stroke in each direction. A 2 stoke engine will have a compression stroke followed by an explosion of the compressed fuel. On the return stroke new fuel mixture is inserted into the cylinder.

A 4 stroke engine has 1 compression stroke and 1 exhaust stoke. Each is followed by a return stroke. The compression stroke compresses the fuel air mixture prior to the gas explosion. The exhaust stroke simply pushes the burnt gases out the exhaust.

A 4 stroke engine usually has a distributor that supplies a spark to the cylinder only when its piston is near TDC (top dead center) on the fuel compression stroke, ie. one spark every two turns of the crank shaft. Some 4 stroke engines do away with the distributor and make sparks every turn of the crank. This means a spark happens in a cylinder that just has burnt gasses in it which just means the sparkplug wears out faster.

Thanks for sharing Makita Drills

I have 3 street legal 2 strokes. All are Yamahas, 74 rd 250, 74 rd 350 and 77 it 400. The 250 has spec II pipes, tzr 125 pistons and Dunstall rear sets. It really screams above 6000 rpm, earplugs inside the helmet are recommended. On a quiet night my brother can hear me from 2 1/2 miles away going through the gears. The 350 has DG pipes and Motocarrera rearsets. It is fast and stops better due to having a disc brake. The it 400 is an enduro that is street legal in Michigan. It is stock and quite fast, 80-85 on the dirt. It is the 1st generation of monoshock rear suspension. I am impressed with the powerband and suspension. The brakes are fine on trails but would not be so good for heavy use on twisty pavement. They are all a blast to ride and easy to work on. Parts are relatively easy to find and cheap if you look around.

One of my friends has a NSR250. He's tried to sell it to me a few times, but it's usually out of my price range.

I just picked up this street plated KDX220

KDX's are such cool bikes. Kawasaki really got that one right. Only thing I'd change (other than big springs for my porky butt) would be to flatten out the seat/tank junction. Does it definitely have a WER steering damper? Reason I ask, I never thought the ones I rode needed one.

Not a street bike, but definitely a legend:

The infamous Maico 760cc 2 stroke single. No, that's not a fatfinger: 760cc single.

KDX's are such cool bikes.

I keep hearing that, even from the orange crowd. I want to get out of the mx for a while, and try some harescrambles. It was either this, or a plated KLX300, and I found this first.

That one's a 2000, but I also have a 05 with pipe, reeds, and soon to get KLX300 forks, and a lowering link. That will help with the height, and soften up the rear a bit for me. When I take an inch out of the seat that should allow me to actually flat foot it, too

I've ridden both. The KLX300 has a great motor but the chassis and suspension are sorely lacking. I'd snag a KDX200 over a KLX300 in a second. And I am a four stroke nut.

The 220 had a smaller carb than the 200 but the 200 carb is a bolt on swap and it then makes better power. The 200/220 is so flickable that it makes anyone feel like a hero, which is A Good Thing. I think it's the equal of the KTM 200, which is the class standard.

That's not to say they are bulletproof or perfect; a good friend of mine's son broke his KDX 200's frame in half just behind the steering neck. I helped carry it out of the woods. No, he's not a big guy, he's maybe 165 pounds; I think it's because he just rode so damn hard and fast. I have also heard of rear shock issues like blown seals.

I've never done either of course, but I assume that one gives your vision a purplish haze. Would be easy to determine with a little experimentation.

Wow, I've never heard of broken frames. The 300's have a rep for cracking there, but not the 200/220's. The 200 is has a little bigger carb, and slightly different porting, making them more aggressive like the KTM 200. The 220 has a much friendlier powerband - better for me. They are otherwise the same bike. The suspension on the the KLX, and KDX is practically identical. The other bike in the pic is a KLX250s, the street legal version of the KLX300. Other than being too heavy (street trim), it's quite good in the woods. The KDX I'll be able to use on the natural terrain mx tracks I ride. The 300, not as much.
