So, is this maybe something specific to H1R more so than just a blanket statement "don't run synthetic 2-stroke and petroleum based oil in the trans at the same time" type thing? What type of base does H1R use that is very different than other 2-stroke ... more »

So mixing of synthetic with petroleum is the problem? How do you account for the fact that semi-synthetic 2-stroke oils are synthetic in a petroleum base? For example, I run Super-M premix so essentially I am already mixing synthetic and petroleum and ... more »

There's a pre-season warm up race March 8th. Entry list is unclear but Narita is pretty confirmed. We might get lucky and see some hints of new tech.

There are some limitations and complications specific to the YZ250 carb that really become a hassle when trying to clean/restore one that has been allowed to sit with gas in it. There are some very fine passageways that get easily clogged with corrosion ... more »

Nothing wrong with it. I have both but I prefer the regular length Power core. It kinda splits the difference between the shorty and the stock silencer. The power is more barky with the shorty, as in, it runs through the revs quicker and then drops off ... more »

What type of gas and premix was in the carb while it sat? Please don't say castor oil. If so, you may be buying a new carb. Been down this road.

FMF pipe, FMF power core silencer (not the shorty), Boyesen Pro Reeds, Head cut to correct squish, race gas. After that get the jetting right (I am at 42.5 pilot and 400 main with stock needle) and then gear it to get the shift points how you like them. ... more »

The 250F steering stem is shorter than the 2-stroke one. Might be able to press both stems out and put the 2-stroke stem into the 250F bottom clamp.

A lot of people have had feelings like this over the years. The snell standard does things like try to drive a huge metal spike through the shell (point load) and mimic the helmet slamming into hard corners like a curb, things that would be likely encountered ... more »

I already saw the full test so I'll spare you the suspense. The forks suck, the brakes rock, the engine is deceivingly fast, it was jetted spot on for our sea-level Mediterranean climate, and, of course, add 1 tooth to the rear.

Isn't C12 leaded? If so, not a good idea to put it in your truck, or anything with a catalytic converter.

Detonation usually happens under a heavy load and/or when the engine gets good and hot. You won't be able to tell on the stand like that.

My buddy has a 2003 RM125. All tight, fresh, jetted all that. He rode my 2006 YZ125 and now hates his RM125.

Just another reason not to use Castor oil. Sucks to have to waste some seriously expensive race fuel because it has castor in it.

Yes stiffness is good for power transfer, but it's also good for road vibration transfer, unfortunately. I had an aluminum framed road bike. It was stiff and quick but buzzed my hands and ass numb. I have a carbon bike now and it's noticeably more supple ... more »

Some guys just put a bigger 320mm rotor and bigger caliper on front and leave the back stock like Seth above. This is OK as long as you do not overuse the rear brake. If you use the rear a lot you will cook a stock MX brake. There are other things to ... more »

What bike are we talking about here? Putting a 5" wide wheel on the back of most MX bikes usually causes clearance issues. The edge of the tire might rub the chain and the rim might rub the chain guide bolts. This can be dealt with in numerous ways. ... more »
