    Looking California feeling like Minnesota:
    Looking California feeling like Minnesota: As the series hits the East Coast swing Ryan Dungey normally hits his stride by clicking off wins and asserting his dominance.  This year is proving different.  Musquin and Tomac are stronger and can sense a vulnerability in Dungey we have not seen before.  Are we witnessing Father Time catch up with Dungey?  Is he injured?  Did the Roczen injury mess with his head?  These are all factors I hear fans discussing.  I have a friend who is close to the riders at the Bakery who told me Dungey is suffering from an Epstein Barr/Mononucleosis type of illness.  While I am not 100% sure about what's going on with Dungey, clearly something is off.  Riders who are overworked and under fed (Aldon’s program) is news we have heard before, most recently Ken Roczen was extremely critical of the program. Assuming this is Dungey’s issue, Musquin has to know what is going on.  Training alongside your competition with an “iron sharpens iron” philosophy is how the riders in the Bakery train.  This can be a huge benefit to the riders, until they are attempting to hide a weakness from their main competitor.  While Musquin was riding high with confidence after his win in Dallas, maybe he had inside knowledge about Dungey struggling late in the races and that is why he charged hard late in the race.  I can't ever remember watching Dungey get repeatedly caught and passed at the end of races.  With 9 races, and two riders within 24 points of Dungey, the championship is wide open.  While 3rd place isn't a bad finish, Tomac gained 5 points and Musquin gained 2, it’s getting interesting. Loved seeing the 250 East guys.  Every rider wanted to come out swinging and establish themselves as “the guy.”  Confidence is important in Supercross, probably the most important thing a rider can have as the first race establishes the pecking order.  Joey Savatgy did what most experts predicted.  While his performance didn't overwhelm the competition, a win is still a win.  Jordan Smith may have found what had been missing the last few years.  In the past we’ve seen flashes of speed followed by spectacular crashes.  He rode solid in the Main event providing him the confidence needed to make him a consistent podium guy and maybe get his first career win this year.  Zach Osborne is desperately trying to get his first win and it shows, he is not content with a podium finish.  He will win or crash trying.  Round Two in Atlanta will be make or break for both Alex Martin and Christian Craig.  Martin’s night ended in the first turn with a vicious crash, hopefully he will be alright for Atlanta.  Craig had a bad start and got caught up in first round mayhem earning him a 12th place finish.  He will need a podium in Atlanta to get back in this championship. We are seeing the attrition of Supercross taking a toll on the field.  Last night we lost both Cooper Webb and Justin Bogle, not sure how bad their injuries are but both walked off and Bogle said via Instagram that he will be racing in Atlanta.  Webb’s injury looked severe, when somebody grabs their arm and immediately walks away from the track, not even removing their goggles, I get worried.  These guys are gladiators and being dramatic about injuries is not something they do, this isn't Soccer or Basketball.  Hopefully his injury isn't serious, we’ll find out in Atlanta.

    Help! - Bike Only Starts When Pushed
    Today I want to talk about a situation I hear all too often. Someone’s bike, whether it be a two-stroke or four-stroke, only starts when it is pushed. Before I discuss potential causes for this scenario, take a moment to think through the situation yourself. What mechanical factors would result in either a two-stroke or four-stroke only starting when it is bump started? In either case, the reason the engine is able to start when it is push started is because it is able to build more compression than it otherwise could when it is kicked or the electric starter is engaged. More compression is achievable because the cranking RPM is higher than what’s possible with the aforementioned starting methods. With a higher cranking RPM for a four-stroke, more air will fill the cylinder on the intake stroke, and for a two-stroke the scavenging process will be improved. With this being the case we must look at reasons why the engine is struggling to build compression in the first place. Starting problems specific to four-strokes: 1. Valve seat recession - When a valve seat wears out and recedes, the valve moves up towards the camshaft. This leads to diminished valve clearances and if left to run its course, the valve and shim will bottom on the camshaft’s base circle. The next time the valve clearances are checked the problematic valve will be re-shimmed so the clearances are correct. Once this is done, the valve will have a gap between it and its corresponding seat. 2. The valve is bent - A valve with a serious bow to it may get jammed up inside the guide and not return all the way back to its seat. Bent valves typically result from an over-revved engine where the valves contact the piston. Valves can also bend to a lesser extent if they were mated to valve seats that were not cut concentrically to the guides, or they were paired with worn seats. 3. The valve stuck in the guide - This is usually due to the engine overheating. When the engine overheated the clearance between the valve and guide diminished which caused metal to transfer from one part to the other, ultimately ruining the surface finish on one or both parts. Once this happens the valve may be prone to sticking in the guide until the engine warms up. 4. The valves and seats do not seal well - Worn valves and valve seats can compromise the seal between them. Valve and seat wear is a natural part of running an engine but can also be accelerated by ingesting dirty air. Starting problems specific to two-strokes: 1. The reed valve is worn - Reed petals that don’t close all the way, are chipped, or bent will not allow sealing of the crankcase and efficient gas flow up from the crankcase into the cylinder. 2. An engine seal or gasket has failed - A two-stroke engine requires a well sealed crankcase and cylinder in order for it to scavenge gases efficiently. A worn crank seal, leaky base gasket, or problematic power valve seal can all make starting more difficult. Two and four-stroke problems: 1. The piston rings are worn - Worn piston rings will allow compressed gases to escape past them. 2. The head gasket or o-rings are leaking - Usually a leaking cylinder head will be accompanied by white smoke if coolant is being pushed into the combustion chamber, by coolant being blown out the radiator, or both. I hope you found this rundown of potential problems useful for diagnosing bikes that like bump starting over a kick or the push of a button. Can you think of any other problems that would lead to lack of compression? If so, leave a comment and share them.
