the first thing that failed on 3 of the 4 gas gas bikes my buddy nick had was the 6spd trans, next was crank bearings. a 200, a 250 and a 300, one 250 was just rebuilt when he got it and it lasted til he traded it in. did they notice any differance in performance before failure and approx how long ...

I am pretty sure the distance the timing tab on the flywheel is off is equal the distance the pickup coil is off from a cr250 you know I did not word that statement correctly, the distance the tab on the flywheel is off is equal to the distance the whole stator plate is mounted differently than a c...

there is a possiability that would be true, I am pretty sure i did try all the 125 pieces together and it was the same but I may wrong. If I happen to setup the bench tester I will double check that but I am pretty sure the distance the timing tab on the flywheel is off is equal the distance the pic...

I tried heating and bending the early style for a 4 wheeler once but it needed to much bend to it and it was a failure.
I ended up using a steel kicker from a xl600 or something like that.
The steel is much more willing to bend

I have twice had to flush a motor out while away from home in order to run the rest of the weekend. Both times I used a self-service car wash and flushed with lots of water. Volumn is what will get the small particles out, then since I already have premixed alcohol in the trailer I finish flushing w...

below is the Krizman KS-650 that is the basis for turbine style spark arrestors.
Krizman patented these back in the 60's I believe.

The 125 stator is actually a nicer piece, theres no mid harness, so its hardwired from pickup to the CDI plug. Very nice. and they're been reasonable $ to get ahold of. roost are you talking about early year 125 stators my 2000 cr125 is just like my 250 but the rubber seal that gets squeezed betwee...

Roostius_Maximus wrote:old 125 stuff was the same taper, but shallow. it wouldnt seat as far. The 2000 125 flywheel is lighter than the 2000 250 or 2003 250 flywheels, but almost identical size.

I measured both and the 250 was 439grams the 125 438grams

O.D was within .001 of each other

same taper

weight is the same, it is a noticable differance for throttle responce at lower rpms

Ok I did a little closer looking at my 250 and 125 stators The stators look visually the same as in the pickup location and mounting of the 8 coil stator but the reason it does not mount on my cr500 is because of the location of the rubber seal that is sandwiched between the cover and the case. It i...

the cr125 flywheel and stator would have to be used as a matched set if it does work. The flywheel is clocked differant because the pickup is mounted in a differant location and it did not seam to work real well with the wire routing so I have never tried running it. I run the cr125 box and like it....

Kelsey from RK Tech is a pretty sharp guy, got to know him probaly atleast 10 years ago on MacDizzy when that was a great site.

I know he use to own cr500's but have not used or really know anything about his head.

I am sure he will not do you wrong

well I did a searching and found a guy that cut one open and guess what its a capacitor-resistor like I said above. here is a copy of the post: MotoBikeMike07-08-2005, 07:16 AM I havent done anything to mine yet. It will certainly become an experimental subject at some point. Years ago I tried a Ans...

..explain to everyone why when you remove .273" from the trailing edge(right side) on the tab it will advance your ignition timing 7 degrees on a 250r flywheel. What does physically altering the flywheel have to do with a inline doo-dad? Really not much just testing your knowledge of ignitions...

... and will normally give about 2 degrees of ignition advance. It cant. You can splice some kind of device into the wiring harness to retard the spark ( i.e., delay the signal from the CDI to the coil) but how can a device be spliced into the harness to advance the spark ( send a siginal that hase...

Actually roost boost works as designed just not as perceived.

Roost boost is installed in the pickup circuit and will normally give about 2 degrees of ignition advance. But does nothing in the way of more power to the spark plug

Clyde I need your numbers off your 48 lectron you got from Dennis the one I have just drowns my bike out until 3rd gear what is the measurement of your needle installed. my bike is at 2.012" when you measure from the brass to the end of the needle. I believe Packard only has one needle that is...

If your spacer and 1 gasket equals 5mm than your port timing and cylinder head squish will not have changed.
Don't worry about the extra crankcase volumn it's no different than the 87-01 motors.
The long rod will help with piston wear

I have a 55 gallon drum of vp m1 that I picked up cheap off a guy that got out of racing but the methanol I get up at silver lake MI cmes bulk at a dealer outside the park, the dealer sells TORCO so I would think maybe it's from them. I have not seen a difference between them. My motor has a cool he...

Alcahol is 124 octane, this allows you to run a much higher compression, take advantage of that. the reason you use 2 times as much Al to Gas is not that you are burning 2 times as much, the cooling effect of Al is because there is a large amount that goes out of the exhaust un burnt which carries ...

I respectfully disagree that a gas motor 2 stroke will make more power BTU's is the answer your motor runs on the amount of BTU's you can burn creating a stronger push from the expanding gases. Alcohol burns at a higher fuel ratio thus allowing more BTU to be expelled and creating more power. Funny ...

the pump is a margin of safety thing especially if you do long WOT runs. But I do know allot of people that run without them but then they are only 75.00 and run off the vacuum of the motor so they are easy to hook up. the 44's are allot cheaper than the 46 48 and 50's and most guys will do fine wit...
