The good, The bad, And the ugly
The Good: Hey, it's all good! As long as you don't watch tv, listen to news, or doom scroll. Life in Mack is good. I have to admit that despite the grind of it all, I really live the life I love and love the life I live and all that kumbyah hippy shit that has got me this far without loosing my marbles or at least all of them. On the righteous straight and narrow path of hot nasty dirty speed I have been able to somehow keep my nose to the grind stone. Ouch, sometimes i get sparks in my eye. But did manage to get some lead out my ass and hook up the distributor on the Coyote and feed the Holly double pumper some petrol. The sawed off header pipes did not disipoint and my dog was not the only one who piddled on the floor from excitement. Damn this capsule ought to be more fun than barrel full of well oiled midget monkeys doing keg stands of Jolt Cola on a marry-go round.
And to the bad: Not so bad but, well shitfuck. What did I expect slapping a four wheeler head onto a dirt bike engine with cam lobes the size of Dolly Parton's hoo-haas and gallon coffee can for a piston. I even filled up the radiators with green stuff I was so optimistic/naive/eager to start the beast... And the kicker stopped dead locked up.... eeeee, I should have measured the piston to valve clearance. So I did. It was nilch, zip, zero, nada....
I did what any self respecting honkey without money would do and I turned my drill press into a mill. And I cut, and I measured again, and I cut, and I measured again, and I cut, and.... I came to rational thought about how the piston's original valve pockets were not wide enough for the +2mm oversized valves, so I cut wider, and than again deeper. And just when I thought I might not have anymore piston left to cut I finally got hit in the head with the apple of reality. My valves were only hitting the piston after a revolution. I had the god damn good for nothing scum sucking TRX four wheeler cam sprocket which has two less teeth than the sweet familiar CRF two wheel cam sprocket. I really should have noticed. Life is learning. Hoping my valves are not bent. They seem to hold pressure fine. And hoping my compression ratio is above barometric pressure. If things progress into combustion of holly rolling happiness than praise be I shall buy a new piston. Another brand new big bore expensive ass piston. And measure clearances. Which finally brings us to the ugly; my favorite. I was just minding my own business when Dylan the bloke who beat me in the CHCA motorcycle points championship once and made me a red plate of his number 1 to hang on my wall sent me a text with a link to a marketplace add. It read: Free Yard Art. Doh! I showed up and they were waiting for my on the curb, actually off of it into the street with the poor old bike loaded vertically onto a dolly like Hannibal Lector. They asked what I intended to do with and did not believe me one bit when I told them I was going to revive the 73 MX250. They had even taken the liberty to weld onto it it's very own angle iron center stand that was perfect for busting open my knuckles while I snapped off rusty bolts breaking it down. "As much as I can with as little as possible" - My life's motto it seems. I got it all down and amazingly the stock bore piston and cylinder look great. After breaking loose the magneto, it turnedover free and clean. I dont think I will even rebuild the conn rod but the left side crank seal surface is not happy. Might have to do what I did on the 76 YZ125 last winter. This one might even be something I have to break my crusty patina pervert habits with and powder coat the frame, get one of those Indian repop tanks, and make all purdy and shit... we will see. I better source a new ignition...
emptied my box of band-aids.
I only had to drill 5 of the 3 bolt heads. Math equations aside I have always wanted a proper pre 74 vintage class racer. Lets go!Monday, March 9, 2026
Preparing for 2026; Preparation H
Hill climb preparations that is.
I also do discount plumbing. Plumbed the radiator form the ol Pontiac Grand Prix stockcar onto the side of the Coyote like some colostomy bag appendage. It might not make Collin Chapman approve but as Johny Cash said: " It didn't cost me a dime". Hopefully it does not end up burning my face like a scalded boiled potato at an Irish potluck. Everybody river dance! Hey, if it was good enough to cool the big ol Pontiac with the same engine I am hoping that the fans will make it happen even if direct air flow is about as good as trying to light a fart through gor-tex trousers. Now all I need is some sheet metal to enclose the side pod and create some ducting or at least make it look like a proper side pod. But I'll be damned if I am going to spend $150 on a sheet of aluminum. Thanks Chief peder-ass! Hoping somebody will donate some ol road signs so I don't have to skin my ol camper's siding. State of the union... help!
Onto things more within my control, with two wheels and parts I know how to harvest from trash bins;
In another amazing feat of cheap skate zip zero nada I fit up a homebrew exhaust system utilizing the stainless steal oversize header Gary made me along with some of his beautiful titanium for the mid pipe and to trifecta the metallurgy an old school aluminum super trap I have been hoarding for over 15 years.
First time I have ever ground the valve guide flush with the inside of the port. Just the intakes. Using my favorite seat grinder on this head. Notice the epoxy not only in the intake ports but also blocking the coolant passages near the intake...
Back cutting the valve face.
My math only works out with correct ratio of cheap and fancy beer. The PVC spacer goes inside the intake manifold to match carb to intake port size.This required taper boing the inside diameter. I only hope the pvc will not melt when playing with gasoline...Fits better than OJ's glove. Life in Mack is good. At least at the motorbike shop. Peace.

94 Pikes Peak Hill Climb

Getting through the winter hump
It is the time of year that the racer finds only solace in the shop. The gear bag is giving bed to the dust bunnies. The sun shine rises late, shines low through windows giving new perspective and light to the dwelling artifacts of the shop, and then the ball of fire sets too soon to do mini bike laps in the back yard. The porcelain tea mug has darkened with stain growing long in the tooth hoping to avoid the cement floor, an immanent demise of all the racer collects and drinks from. Beyond renewing the race club memberships and reserving the holy number not 666 but rather 747, there are other responsibilities. The father, the husband, the maintainer of house and cars. Damn you Mr. Ford. The owner and operator of a full time busy as all hell motorbike shop. The balance. Constantly seeking the balance. Years are few and dreams are many. Will this be the year to focus on taking a race car to the next level. What comes after a class title. Both bike and car, was a lot but addiction says: more, more, more, If you can do it once do it more. The madness is both numbing and captivating. To take something from the brink of the trash bin and put it on top of the podium. That first Pikes Peak win ruined me. It showed me that all the consumer based advertisement fueled colosseum scene is a lie. All the money in the world will not build a race winning vehicle. The desire is was counts. Ambition, work, limber optimism, and bit of JB weld.

Here we are. There it goes. Where it's at.
Finally have shifter. Shifting gears. Metaphor of life.
Grab too tall of a gear - blow the corner.
Miss a shift - make a savings withdrawal.
Smooth transition. Not grinding. Not missing.
Finding it. Minding it. In the shop I keep grinding it.

Blue lever is the twin master cylinder turning brake. Push to go left and Pull to go right or is it the other way? ... Think fast - don't die.
Not a lot of room. Not a lot of aluminum welding skill. But I just keep on finding a way. I tell my daughter constantly; "If you can think it- you can do it"
