  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Gas for new 250 motor - Pump or Race?

Hey,
Curious what those of you who already have the new 250 motor (TC, TE, or TXC) are running as far as gas goes? Are you running what you have run in the past or jumped up to a better fuel. I notice the compression in the new motor is 13.6:1 which is quite high therefore I didn't know if anyone has tried the standard 92/93 pump gas? In my 450 all last year, I ran Shell or BP 93 Octane fuel BUT in 2007 I ran 102 Octane Sunoco in my 250F. Just curious what everyone is doing. Thanks

Hey Blake,

I know in the manuals of both my bikes 08/510 09/125 it states. "Premium grade unleaded fuel (R.O.N.) Research Octane Number 98 or better.

Anything different in the TC's manual?
 
I have been running Shell or BP(Amoco really) premium in mine. I am scared to do the race fuel right now until I get a little more educated with the titanium valves/injectors etc.. I used to run MR-9 Oxygenated in my mini supermoto bike. I call that stuff the Herion of race fuel.
 
I've been running a blend of 66% pump (93 0ctane) and 33% race gas in all my bikes for years with great results.
 
Remember octane does not make h.p. Run as low a octane you can with out getting detonation. Here again everyone like to spend as much as they can on fuel and oil and it is not needed. Ive got a street bike that dynos at 194hp at the rear tire and that is on 87 octane with no spark knock. If you do insist on running the oxygenated race fuels make sure you drain the fuel after each race or it will clog up the whole fuel system. Im not trying to be a know it all but this is knowledge ive gained from hot rodding for most of my life.
 
I run chevron super in mine. Noticed no pinging or detonation. Runs great.

- totally agree...
