Technical / Sound Testing unfair to the two stroke
« on: April 13, 2013, 11:41:14 PM »
If you buy a house next to a train track do you potest the train company to move the track? If you buy a house next to an airport, do you protest to move the aiport?  If you buy a house next to a busy highway do you protest to move the highway?

They do it because of the perseption is that they can and they don't like the dirt bikes to begin with.  I've been in neighborhoods where a train was next to the houses, the houses completely rock and shake when the train goes by and sometimes they go by at 5am.  People there suck it up or don't buy a house there.

General Two Stroke Talk / Amazing Find
« on: March 18, 2013, 12:13:06 AM »
So, currently I am in St. Lucia (a small island in the caribbean) and the airport is on the very south tip of the island and the hotel is on the very northern tip of the island.  There's one road that goes through the island basically and so I'm driving and half way up the island I hear a 2 stroke.  I look over and there's what looks like a very nice looking RM 250 (or maybe 125) blasting around a dirt track, doing jumps, and of course a cow sitting near by.  Needless to say I pulled over and took out my video camera and got some footage.  I'll have to post it when I get back, it's nothing special and I'm blocked by follage but still, a 2 stroke in a track in the middle of the caribbean islands is a pretty unquie site :)

PS The only thing that could have made it better and more amazing is if it was a MAICO (and you can take that to the bank GlenC!)

Vintage Two Strokes / Maico Gas Tank
« on: March 12, 2013, 05:16:54 AM »
http://www.ebay.com/itm/1981-MAICO-MC490-T-MC490-T-MC-490-T-MOTOCROSS-GAS-TANK-/171005553571?pt=Motorcycles_Parts_Accessories&vxp=mtr&hash=item27d0b9aba3

These used plastic tanks are becoming more hard to find so most people are forced to buy new ones for $100.  Can't find them like this one anymore, he's got some gold on his hands.

It's pretty good riding out here :)  This is just one of the trails close to the parking lot.

Still a fan of the left side kick, I've gotten good and creative at starting it in tough places but accidents happen!

Vintage Two Strokes / RM250 Rebuild
« on: March 09, 2013, 05:37:49 PM »
2 Stroke ports are "chamfered", i.e. rounding off the ports so they aren't sharp edges.  This prevents wear and tear on the piston and rings as they pass over the ports (i.e., like going past a gillotine every stroke!).  4 Strokes have valves at the top so they don't have to worry about that :)

Yep know all that.
Was talking about the 'ramp' in the inlet tract.

Ah ok, I misunderstood since the last picture of the ports was the one shown by the question and I skim read so I just saw Ports, the last picture and assumed it was the chamfering lol
