Hi Guys, nice forum

I have just bought a 2007 YZ250F and have been doing a litle work on it (valve clearances etc).

Just started in the shed and ran it for 5 or so minutes and the head pipe started to glow red for about the first 3 inches or so.

This is the first time I have noticed this as previously I have only run it outside.

Is this normal or do I need to take a really good look inside the engine.

Valve clearances are well within tolerances now.

Fond du Lac, WI resident, Perry Prichard is setting out to do what most think of as an impossible feat. He’s going to ride his motocross bike on a motocross track for 24 consecutive hours.

When Prichard and his wife Melissa tell people what he is going to do, the first thing out of most mouths is, “…are you out of your mind?” Prichard would somewhat agree, but follows that up by adding that, it’s worth it for such a great cause…

Prichard had a dream – a dream of combining his passions of riding motorcycles and providing help and relief for the people of Haiti. That dream brought him to the idea of 24 Hours for Haiti, a fund raising event set to be held on Sept 11th and 12th at Gravity Park MX Track in Chilton, WI.

Just a few short months ago when Prichard was trying to come up with ways to raise money for Haiti to help with the relief of the devastating earth quake, some family members mentioned riding his motorcycle and having people pledge per hour or per lap. Well that simple comment spawned an amazing transformation into something really BIG.

As the event coordination began, an application was also sent to Guinness World Records to see if this was already a set record. In a matter of 4 weeks, GWR replied stating this application would in fact be the first attempt to set the following record; The Greatest Distance on a Motocross Track by an Individual in 24 Hours”

Since receiving the acceptance by Guinness World Records, Prichard has been training like no other, spending hours upon hours with his trainers (Chad Kollmann and Derek Toshner) preparing for such a feat of endurance.

As can be attested to by others who have attempted feats of endurance, it’s not just the training for physical conditioning, but also mental conditioning; the body will only take you so far, then you have to rely on shear mental strength and most importantly HEART. Prichard has also stated -- if it wasn’t for the kids which have now become friends, I don’t know if I could do it, they are my true inspiration”.

That inspiration began simply with a visit to Haiti, working with an organization called The Lazarus Project Haiti. The organization facilitates 2 orphanages, a clinic, and two schools where the children are fed and housed, given medical treatment and provided with educational training. Prichard has made several trips to the country since that initial visit and the man beams each time he shares the stories of his young friends there. In addition to living in an orphanage, many of the children deal with significant physical challenges, “…..they have so little and yet you never hear them complaining, where we have so much and grumble about the littlest things”, He commented during a recent conversation.

Which brings us full circle to, “24 Hours for Haiti”, what began as a thought in one man’s mind, turned into a dream and has now become reality. Please help one man accomplish his dream to raise money for the many, many kids in Haiti that just need some peace. The organizing team is looking for event sponsors and companies willing to help and step out of their comfort zone and show the world that they care.
Prichard always says, “If a lot of people give a little bit, it will make a BIG difference to so many”

Hello I am new to this site and hopefully you gus can give me a few tips or help me out a little bit.

I bought a 2003 YZ250F Non running. The kid I bought it from said it just died on him.

This is the 3rd 250F I have owned so I figure I will give it a shot on getting it running.

I took the motor out of the bike checked the timing and it seemed like it jumped a tooth or two. Took the head off and no broken or bent valves everything looked good including the cylinder. Put it all back together set the timing to what I thought it should be from reading about it and watching you tube videos. Got the motor back in all back together and it seems like it wants to start but it wont.

I try to pop start it in every gear but the tire does not spin it just drags.

I have spark, fuel, and I believe compression when I put my finger on the spark plug hole it blows it off.

Now my questions are.....What should I look for that would cause it not to run? What should the timing be?(pics anyone) I paid $500 for the bike is it worth it to invest money into it or just sell it? :money

Had read the entire post from (YZ125 (2003 & 2005) No Spark ) I have a similar situation. I have just completed a top end. Have everything completed and found no spark. Changed spark plug and checked all connections no difference. I checked resistance in the coil seems ok never checked voltage output however. I opened up the rotor assembly and checked resistance of the pulse coil and the source coil and seemed good. I do not have the specific manual I have a clymer but no real readings. I will tonight check the voltage output and see what I can find. The clymer manual says to have the dealer check the CDI. I was hoping someone here could tell me how to check it. I have 3 other CDI's for my yamaha sleds but different wiring to check against as the YZ80 has a plug and not individual connections.

OK, about a year ago I started cleaning my chain while cleaning the bike with soap & water. Then I blow the bike dry with a gas blower.

Then I get a rag and liquid wrench silicone i spin the back tire while spraying the silicone onto the chain with the rag very wet with the spray and dragging the chain with left hand as spraying with right.

This has resulted in a very clean, shiny, well protected chain.

What I'm wondering is if anyone thinks this is bad for the chain/gaskets/chain lubrication.

I have not had any issues yet and have been doing his for quite a while. My chain/bike stays much cleaner.
