Shop has been very busy this year. I was racing a new 961 last year, but it was not competitive in the class it was assigned to. So I went a different direction this year. I talked to Kenny Cummings about a Bears bike. He said sure I then talked to Jim Comstock about a fire breathing engine, and he said of course.

Kenny wrote this about the bike:

A bit about the Seeley Commando, built to John Snead's spec by NYC Norton:
Roger Titshmarsh Seeley MK2 Replica chassis fabbed from Renold 531 tubing. (Motor details separate). TTI Magnesium 5-Speed Close Ratio Gearbox, Keihin CR35mm carbs, custom stainless 2-into-1 exhaust, modified and lightened Commando clutch, Triumph T140 Billet rear hub with cush drive. Production Racer front hub with 11.5" drilled disks and full compliment of sprockets. NYC Norton lightweight yokes, Roadholder forks with Cosentino shim-stack internals. Seeley MK2 Tanks and MK4 seat. Kirby Fairing. Avon tires. NYC Norton rearsets. Bike weighs ~295lbs dry. It is the sister bike to NYC Norton's 4x championship winning Seeley Commando.


I will let Jim add his comments (but to start it has billet cases, Fullauto Head, and Jim can expand)

Great work from both guys.

Here are some pics

Re: Been a while Here is the newest Bears Bike from Comnoz

Nothing like the looks of a Commando Seeley on the birthing table. A couple of questions:

- What is the "hatch" looking hole near the top front of the oil tank right behind the carbs?
- Did you have the outside of the exhaust pipes ceramic coated - they look polished.
- Dyno charts?

Wow.

Properly impressive !
 
Re: Been a while Here is the newest Bears Bike from Comnoz

Very cool. I have to ask, what stock Norton parts are there on the bike? I am guessing the valve and timing covers?

I doubt even those covers are stock Stephen.. Probably custom milled out of some unobtainium metal from outer space...

Based on my own engine build, which did have stock cast barrels (original '70s item) as well as the following I would go for, the timing cover and everything inside, it except perhaps the chain, main bearings, some seals and gaskets, rockers (lightened and polished) and spindles, rocker covers, selection of studs, possibly a few nuts and woodruff keys, and yes, those rocker covers! Budget around $2500 for that little lot alone!

Great bike!
 
Re: Been a while Here is the newest Bears Bike from Comnoz

In the olden days (during the war Rodney) frames were left unpainted to be able to spot the cracks. Probably easier to spot them as you change down the box and throw it into a bend.
 
Re: Been a while Here is the newest Bears Bike from Comnoz

I am likely wrong, but the little grey cells are telling me that guzzi, in their World Championship winning days - when they used to beat the Nortons, weighed the paint on a bike and it came to several pounds.

The bikes got a thin wizz of primer after that.

Crack checking is certainly a possibility but also consider aesthetics. Who would want to cover up those beautiful Silicon Bronze welds? A while back I purchased a Titchmarsh Mk 2 made many years ago. The previous owner had gun black treated the frame where the bronze welds were visible and the frame metal was black yet protected from corrosion. Pretty clever I thought and looked decent.
