AHRMA is going to Heartland Park in Topeka, KS in 2021. They're planning on doing Road Race, MX, dirt track and (I think) Cross Country. Scheduled for May 28th - 30th. (and Google says it's about 5 ho ...

Getting lapped by Jake Zemke on his Ducati at Barber while I was on my CB-F was pretty cool in a "I'll never be like him" kinda way. He passed me on ...

I'll be there racing...

From the AHRMA rulebook....."A restrictor plate may be used where a minimum carburetor size is speci ed. A re- strictor plate must be at 1/8-inch thick with a constant diameter bore no larger tha ...

I've known that at least one of my competitors have run bigger carbs with restrictor plates - it was several years ago and I can't remember if he ran 33s, 35s or what, and it was on a Z1 with a J-head ...

On 2 stroke bikes, I never had to worry about oil starvation. But doing wheelies on a vintage/valuable/heavy bike just doesn't make sense to me. If your oil pressure light comes on when you are at tha ...

Just do it! Pretty much anything (almost) will wheelie - I used to do them (balance wheelies) on my SOHC 750 and Z1 too. This is around '82; I treat my CBX much nicer now then I used to when it w ...

Toddk, Simply Yes! By cutting an inch out of the frame and tucking the head in a degree it turned in quicker and had more weight on the front tire. Very neutral in the corner on the gas but if you cho ...

Dennis, just view it as a slight difference in equipment Laughing

It's tempting to give myself some ego strokes and blame my equipment. However, I can easily identify "faster" when I see it ...

Congratulations on winning the motorcycling ashes. See you next year!

P.S. This great event could be even greater if the U.S. team were more competitive. It'd be awesome to see some of your past ch ...

More is better - it should be MORE Bikes Syndrome so that whatever you have, you want more.

Some of my bikes, but not all:

They have us beat, that's for sure. AHRMA needs to take notes and they will get better turnouts.

The only event that ARHMA currently is involved with that could compare at all would be the Barber ...

Bike is all ready and has the latest software updates.

Captain

This made me laugh - a measure of how far things have come since these were new, and how much tailoring can be done without weldin ...

I couldn't make it this year. Will Brint is riding a CBX (#118) in Vintage Superbike Heavyweight. Kim Muhr is riding a mostly stock CB750F (x55). I gave her a set of 900F cams and a some valves aft ...

Jim sent me a FB message .... unfortunately the yellow bike gave up during the first race and DNF'd.
Dennis reported it's faster than his though. Well not bad for a brand new engine/chassis combo.

Is this the same Yoshi Kosaka? http://www.garagecompany.com/

Yep - very, very nice guy. We chatted with him in the pits. The bike he raced is STREET LEGAL - the horn still works!

Right now there's an infinitesimal chance I'll be there - hopefully with Jim's Yellow (Yellow must be capitalized as it appears to be VERY yellow) bike. There's a lot going on at work and home right ...

I drove for 7 hours total, yesterday, to go hang out with Jim & Brent... Well actually help work on this bike too.. A Whole Lot of TRICK parts on this bike!

This will be a fearsome, Brent Hyd ...

The CB-F composite head gaskets come both ways depending on who made them - round and 'ovoid' near the valves. Both work fine.

That looks like a clever application of using ratcheting straps and a beam to allow you to slide that engine into place....Did that allow you to do the job by yourself?

Made me go look - in a billi ...

The recommendation from AHRMA is for an oil absorbent mat inside the belly pan, this needs to be secured in place, a bung or drain plug is also a good idea. Get caught in the rain and the pans fill w ...

Dude. Looks like some of my carpentry work........

I had to laugh when I read your response. I saw another x-ray where they were holding the pieces together with a huge hemostat and there's a ...

Mostly the belly pan is just to contain the oil dump from catastrophic failure - plus it keeps all the parts right there for quick reassembly! The belly pan is usually just a pan with nothing in it a ...

I also got the peg mount's fab'd up and on the bike. The pegs are in the same location as Euro style foot plate's. This is what Dennis is use to and his knee's don't like to bend anymore then this ...

I ordered two Shorai batteries and the charger last night. There went another $463.00 with shipping. Shocked

Jim, which Shorai batteries did you get? I tried running the 7AH battery a couple o ...

Yesterday I shared with Jim that I gave myself a year to build my first race CB-F. It took two full years.

The first two years of racing the CB-F resulted in a ton of debug work. I broke the c ...

Right now the plan is to passenger on a sidecar at Barber, if the CBX survives the season I will bring it to race.

Daytona is a week later, I haven't figured out how to convince my wife this would ...

I couldn't say for sure which set of rules are applied at Mid Ohio, I don't remember seeing anything close to WERA specs as a heavy weight Super Bike.
Best to call and get first hand info.

I am pu ...

I read somewhere (and no longer recall where) that they had set all the teams to 10 racers plus 2 backup riders who'd be scored (or compete) if one of the 'primary' members was unable to compete - som ...

When I got invited I couldn't afford to go - and that was with an offer to ship my racebike there for free! My buddies Joe Weir, Dave Crussell and Brian Filo are going there again and have nothing bu ...
