Sand dune ride. Blown motor at end
The blown motor part is at 1:55 Riding at Gordons Well, Californa. 12/30/10 It was just my warm up ride but ended up being my last ride of the day. It broke from my carb's fuel screw being turned to lean, jetted too lean, no paddle tire ( i was literally gonna put one on right after this ride) The sand was really packed that week because it was raining everyday.

SV650 with CR500 engine
I always wanted a big two stroke street bike, and since the SV650 frame was narrow I thought my nice CR500 engine would work out well. Honzuki SVCR500S (SV650 + CR500) Build Transformation I bought a $200 '01 SV650 and rescued it from a trailer park. The engine was removed by the previous owner because it was knocking. It had also been painted all over in a sloppy mess with no masking and no proper disassembly. I spent a few weeks in my spare time stripping, cleaning, and blasting the thing into shape. Underneath all the crud and excess paint was lots of nice bits in decent shape. A cradle was cut from an old CR500 frame that had been tweaked and mounting tabes were welded onto it allowing the SV650 engine mount bolts to work in their factory mounting locations. The trycky part was the kickstarter shaft. It had to be lengthened to clear the frame but d@mned if we are, it broke 3 times after modifcations. This was the Achiles heel of the project and caused me to become disgrunted and frustrated with it. I parked it in the back corner of my garage and over the months it wound up buried under other garage junk. Some time later a low-mileage '06 SV650 engine showed up on Ebay, and with an Ebay coupon I got the engine for $186! Once I got it home and converted the second generation engine to my first generation chassis and mounted it, I was suprised to find that it started immediately, though it smoked something serious... the engine was shipped on its side and the oii drained into the cylinders. Once that blew out the engine ran well, and is still running well... 10/4/10 - UPDATE! - Best of all I sold the old dead engine as parts for $170, so really tne new engine cost me $16!!!!!!! Really cool project for under $500! And the CR500 engine is saved for the next project! :)

How to diagnose carburetor vacuum leaks on your motorcycle
This is a simple video demonstrating the best method to detect vacuum leaks around your carb boots. Vacuum leaks are a fairly common problem in older bikes, and luckily they can usually be remedied quickly and easily, the first step however is diagnosis. If your bike is running rough, won't rev up or has an irregular idle, before you take off the carbs and open them up, check for vacuum leaks. A vacuum leak occurs when too much air is introduced into the combustion chamber via a failure in one or more of the carburetor boots or other rubber mating surface. When too much air is sucked in, then the bike cannot combust the gasoline efficiently; there must be an optimal ratio. Therefore it is up to you to detect these leaks, and either plug them up or replace the carb boots. In this particular bike, the engine was running VERY lean. Not only did we have vacuum leaks, but the baffles were taken out of the engine, and the previous owner had removed the air filter and neglected to install a new one. This is not only dangerous by allowing foreign material to enter the engine, but it also makes the engine run much hotter, as lean explosions create more heat than regular ones (think about blowing on a fire in your fire place: more air, hotter fire). This can be detrimental to a variety of parts in the engine, and it is a good thing we didn't ride this bike around too much before finding the problem. If anyone has any questions as to why this is important or how to find/repair these leaks, leave a comment and I will respond. Thank you

RM 125 Blows up - Go Pro HD
----------PLEASE READ THIS BEFORE POSTING STUPID COMMENTS---------- I had about 5 minutes of riding time on this top end (not counting the proper break-in process.) If you basically threw $200 down the drain i'm sure you would be angry, just as i was. My bike blew up becuase I was unaware that a bearing in my water pump had gone bad. As a result of this failure all of my engine coolant was dumped into the crankcase with the engine oil (producing a milky white substance that drained out the bottom after the bike had gone.) I am very aware of how to ride a 2 stroke and im very knowledgeable of how a 2 stroke engine works and functions. The parts where I hold a gear much longer than I should is due to a HUGE power loss in the bike. The bike was losing power and torque like crazy at the end. Once again I am very aware of of everything thsat went on envolving my bike so there is no need to give me your pointless opinion of my riding style, or anything that involves my bike, especially involving why it blew up.

YFZ 450 Vs YZ 250 (2 stroke). Read description!
1994 YZ 250 Wins a drag race against a 2007 YFZ 450. Yfz 450 mods: hmf full Exhaust...header and silencer, airbox lid, and cotton K&n style filter. 180 lb rider. Yz 250 mods: boyesen reeds and cage, fmf fatty gold series pipe, fmf power core 2 silencer. 310 lb rider Both machines have stock bore, stroke, and engine internals, aside from a wiseco piston in the yz 250. In case it's difficult to see what happens because of the lack of zoom, the quad jumps a full length off of the line and from there on the bike pulls away hard (even with a rider over 100 lbs heavier). the bike let off at the end hundreds of feet from where the camera is because they were both topped out and the bike rider wanted to give the camera some sign language..If you listen to the sound of the bike, it let off LONG before it got to the camera..only then did the quad catch up and pass

03' rm125 blown head gasket
Just a quick update of my my rm125 is doing. When i was taking the cylinder off just a few minutes ago i broke the powervalve linkage arm again so i will have to replace that again aswell.

As always, rate and comment Check out dbiz67x's channel, he should have new helmet camera videos coming soon.
