2008 YZ 450F Engine problems...Skipping 5th gear
By Woody Oakson
So I have a 2008 yz450f and I would like to add some LED lights to it to make it street legal. Mainly just a headlight and a tail light and turn signals if I need to (which where I live hand signals work).
So where I need help is getting power from the stator to a battery. Wiring from a battery to anything else I got and understand and don't need help with (but recommendations are welcome). So my questions are.
What type of power is coming from the stator. AC or DC? Will I need a regulator or rectifier? How do I wire something from the stator to charge a battery? What would that wiring look like? Would this stator http://www.rickystator.com/product/stators/yamaha/yamaha-yz450f-35-watt-lighting-stator-assembly-06-09 work? Anything else I should know? Any help would be appreciated. Thank you.
Alright so I’m new to the site so maybe this question has already been asked. I have a 2002 Yz426f and I want a new exhaust, it has the stock header and silencer and sounds amazing but I’d like a little more from it, I know I want the fmf power bomb header and am kind of undecided on the silencer, I see on fmf’s website that their silencer will add low end and slightly take from top end and the other way around but I’m looking for increases throughout rpm range. I do a lot of trail, hill climbs, jumps, and wheelies so kind of need good performance everywhere in the rpms. My question is what silencer I should get and the jetting I should get for the carb. Thanks

Ok. Last fall after a decently hot day at the track, I noticed coolant leaking from the weep hole on my water pump after pulling into the pits. Ordered an Athena re-seal kit, put it all back together and didn't really get a chance to ride it. 3 weeks ago, went out to the track, and after about 20 laps, it started leaking again. Kept filling it with water to get thru the day, never ran anywhere close to dry or empty, jut a cup or 2 low. Ordered a Hot Rods re-seal kit with bearing and also ordered a new w/p shaft. Did it all again and got it back together, ran it, and as soon as it got to temp, it was leaking out of the weep hole again.
So, what the heck am I missing? I'm totally stumped on this one. Is something wrong with my case cover? Do I need to replace the w/p itself? I'm feeling like I should've just ponied up for the Boysen in the first place, and now it's biting me in the butt. Any help or suggestions is greatly appreciated. Thanks!
