2008年3月25日 · OK - here's a pic of the Moose stator in the stock YZ ignition cover. Note the 2 extra wires - A black wire which goes to the chassis ground, and a yellow wire which is the hot lead for your lights. You will also need either a voltage regulator if you plan on running the system AC to keep the voltage from going past 12 volts and frying a light ...

2006年12月18日 · the only company that i spoke to in regurds to work has been Doug Dubach racing and they said that they don't reccommed running cams in that engine,and from reading different posts across the internet i have read many times that the stock yamaha piston is the best that you can run in that engine....the main reason that i asked for help finding different companys that do head porting is to get ...

2021年7月1日 · So I used a yz426f head gasket with the modified yz450f cylinder (since EBAY seller lied in description and YZ400f cylinder is what I received) to find out you have to use a 03-05 yz450f gasket because now I don't have full compression.

2008年4月16日 · This is a question that gets asked often but there's never really been a comprehensive reference for the info. The info here applies to hubs from any YZ model used in a YZ400/426/450. Thanks to Bob Russell at RTR Precision Wheel Lacing for helping collect this. Here's how it works out: Front Wheels: The front hub is the same from 1997 to 2001.

2004年11月7日 · A yz, as far I know, is a high compression engine n ya really gotta drive your foot through to start it. A lot of people drop their weight to lighten up the thrust or just cause it needs the beans! My YZ is a starter if ya done it right but sure af ain't no Vee-Touch

2013年5月22日 · My problem is i am rebuilding a 2004 yz 450 and im putting the cams back in but they were never marked for timing. my manual shows the two timing marks while engine is at tdc but i cannot get the timing marks on the cam to line up perfectly with the head. the timing marks are a little high on the intake cam and if i turn it back its just below ...

2015年2月1日 · The problem comes when the oil is used in a transmission. The gearbox imparts a very heavy shearing force to the oil, and works to physically shred the large molecules of the polymer additives so they no longer prevent the thinning of the oil with heat, and you can end up running a oil that is really a 5w-20 in a surprisingly short time (as …

2021年2月22日 · Well the whole turbo thing is actually pretty common in the snow bike world. As those guys are racing at a much higher altitude with less dense air.. the turbo is more so used to re-gain efficiency that the engine loses because of it. The KTM’s and YZ’s are actually some of the bikes those guys turbocharged successfully as well. So for ...

2005年4月29日 · I'm happier now with theses changes versus the mid summer specs with the cold weather. Just an occasional pop when chopping the throttle, generally happening when the track is just watered. The bike feels faster in the cold weather. I can't wait to ride a 450 at sea level. Runs better with the 38 pilot jet at 65 degrees. Summer specs:

2004年4月9日 · I had an 03 YZ450 and had to sell it for financial reasons. I loved the bike. When I was able to buy another bike I tried out the CRF 450. It was a good bike, it looked nice, but didn't have the power, handling or suspension of the YZ. I ditched the CRF 450 and bought a CRF 250R in search of lighter weight and better handling.
