Vincent 1360

Nigel, the main problem here is finding a place to legally run at high speed. We had a track with a fairly short straight(Westwood) however that is now a housing subdivision.
There is a quarter mile track at Mission BC and I intend to do some 1/4 mile runs there to see how it does over that distance.
Weight does effect top speed to some degree, mainly thru tire/ground friction, especially on a salt flat, but also on asphalt.
Try a top speed run two up with your Commando, I think you will drop several MPH even though frontal area remains the same.

What about SIR or PIR?

EDIT: Or Spokane has an open Test-n-Tune day this weekend ;-)

Hadn't thought about taking the bike to a racetrack across the line, that could work.
Right now I'm just happy it runs well and that I can actually kickstart it, albeit with steel toed work boots and knee brace in place.
Part of the reason I've left this bike sit awhile is that I had a bit of an unexplainable oil leak thru one cylinder stud and didn't feel like tearing the fresh engine down to address it. That leak seems to be cured now. It appears that it was due to an over filled crankcase, which was a regular startup occurance, after even a couple of days of sitting.
With even an extra half pint of oil in the crankcase, oil was streaming out of the front head at the left front stud. With the anti wet sump valve fitted, the oil level in the sump is always correct and the leak has disappeared.
So I can add this bike to my small group of motorcycles that can be safely parked on a white carpet- The 05 Triumph Daytona, this 1360 Vincent and the MK3 Commando. The rest of the crew are standard leakers.

I will explore the max performance levels of this bike in the future. My early impression is that it
Definitely comes on harder than the 955i Daytona. It will be interesting to see if it can match the Daytonas howling top end power.

Congratulations on Building an amazing Vincent Glen , you have done an incredible job on the beast !
As you refer to my racebike quite a bit in your build diary I must correct you on a couple of points .
I have never owned a 102mm crank or run one in the bike . When I first retired my roadbike from racing in 2004 and built the racebike I originally used a 100mm stroke full flywheel crank from TPV. I had problems with that crank and it never produced the type of power I was looking for. That crank never made it onto the salt at Lake Gairdner due to cancelled events from rain. In 2008 I changed to a 92mm Porkchop TPV crank and that remains in the bike . It has had some modifications done to it but remains reliable . So with 92mm bore and 92 mm stroke the engine was 1222cc (down from 1328cc with the 100mm crank 92 bore),it has never been 1360cc as yours is .
In regard to the footage you posted, That was Bonneville 2010 and you were on the salt with us that year I beleive . We run 151 mph on gas ,1222cc in the form you see . We run 162 mph with a fairing on at the same event.
I wish you all the best and no doubt the bike will make a lot of power .I look forward to reading your results after running in and testing.

Hi Mal
Sorry about my inaccuracies regarding your bike and thank you for providing the corrections.
Terry has given me snippets of info about your bike over the years and somehow I cocked that up. It makes sense that you have not run a 102mm crank . I now recall Terry saying to me a couple of year ago that no one had yet run the exact configuration Engine I'm using, so he was eager to see the results.
Are you by chance running Terry's MK5 cams?
I have them in this bike and am very impressed by the strong (but lumpy) idle and excellent throttle response. The cams along with his bathtub CC squish heads seem to make for a very wide power band.
