My brother is helping out Henry for the nationals and this is what his motor looked like after the LL2 race. It was totally out of coolant and it obviously sucked in some water and dirt, but it held on regardless. Impressive, and he attributes it to the Blud lubricants that they run that it held on. Guys like Henry that don’t have a cabinet in the semi filled with spare motors and have to rebuild their only race motor weekly need all the help they can get to keep racing.

I bet there are a whole bunch of privateers that feel they dodged a bullet by not qualifying.

All I could think was how screwed the guys with just one bike are after that race

What's more expensive for a privateer? Driving from Lorettas to Washougal or conmpletely trashing your one and only race/practice bike?

Tough gig

Free , "do it yourself" Ceramic Coating.......... what a mess.

It's seriously difficult for the Privateers, and small Teams.

Always has been, always will be.

Their efforts are so bloody admirable - they are the life blood of the Sport.

If I opened up my motor and saw that I’d probably throw up.

I had no idea that dirt could build up on the head and piston like that. I didn’t think an engine could survive that much dirt. Ktm ftw I guess lol.

That is not pretty!

1) Well, a 250 2T would be much less expensive to repair. Pretty significant difference for the privateers.

2) I’m a little surprised nobody took a quick pit to spray the radiators clean. I seem to recall doing that a time or two. Maybe they did and I just didn’t see it.

3) Not directed at Miller, but when did the clutch become a tool to constantly control power? Is there another motorsport in the world where guys use the clutch to that extreme?

It’s the fine dirt like flour that gets mixed with the water and gets passed the air filter. The engine won’t have the best compression anymore and it will start burning oil that gets passed the rings on the piston. Still really impressed the engine made it through and kept running. I wonder how much oil was left in the engine? Gotta check out Blud lubricants if the crankcase was dangerously low and no damage was done to the bearings?

Nearly all of drag racing uses a form of slipper clutch. Asphalt and water.

Nearly every automatic transmission (sans CVT) in most automobiles have numerous clutch packs to control speed.

RC decimated the competition for years, and he was an advocate of clutch use....

There is a reason the use a wet clutch...

Point and shoot, using the clutch as a trigger, style of traction/throttle control has been around for years

My first question, I want to know what brand/type filter oil he was using. Because I believe certain types of filter oil are less resistant to water and more prone to allow this type of situation to occur. Or put another way, oil (petroleum) will resist water much better than a substance that its water soluble.

I've come to appreciate having the clutch at my disposal my riding has gotten better and knowing how to use a clutch on a 250 2 stroke is an art form of sorts

On a motor that hammered , what do you think the cost on parts alone would be? If Shredder's brother is doing the work for free , that helps Henry quite a bit. But cost in parts can't be all that cheap I would think.

My bro is just helping out at the races and with some expenses. Not sure who's doing the motor work, but also pretty sure it's not free.

Normal enduro event back in Finland and most bikes you see are KTMs. Just dry airfilter and airbox after swim and good to go. Worst thing is stop when it has water inside motor better just run long as it runs and it will clear it self Smile

Got a little more info on the situation that will give you an idea of what these guys have to put out to race. Henry has 3 motors from Twisted Development, 1 full race and 2 practice. They put one of the practice motors in for this race and basically taped all of the openings up to try and keep out the water. The race motor cost $5k and goes back after 20 hours for a full rebuild. The practice heads go back after 20 hours as well. This motor has 11 hours on it, and now needs a full rebuild, which will be $2500. They're estimating that they're at least $700 in the hole from just that one race. Should've raced the 2 stroke.

Ouch!

A strange business model for the privateers for sure.

Not all that bad considering. Wish you guys the best of luck.

Seeing that makes me appreciate how cheap dirt bikes are to operate. Go to your local dirt track race...Their tire budget will make you cringe, not to mention what the engines cost.
