Commando attack at Mallory

Fast Eddie · Jul 9, 2015

Well, as some will know, the 10.5:1 CR JS pistons and rods, JS stage 1 cam and followers and FCR carbs have pepped up the performance of my Commando a bit, but, what has REALLY made it fly is the clip ons and rear sets (well that's how it seems at least)!

This is how 'The Trident Hunter' looks in 'track trim' and is ready for this weekends frivolities at the Mallory Bike Bonanza at Mallory Park in the UK.

If any of you boys are going to Mallory this weekend do drop by and say "Hello" I'll be in the race paddock.

Bright blue bragging rights, cool.

That front brake should help you go faster !

Just looking at it, I can tell that it is fast. Lots of nice subtle parts there.

I am sure that cNw label will popel you forward past a gaggle of Tridents...

Well, "Fast Eddie" is only my Internet persona, my real name is Nigel...

That label stands for 'Contents of Nigel's Wallet' ...

It's not so bad. I found that the poverty induced reduction in food intake resulted in a few kilo's reduction in body mass, further enhancing performance...

Well done Nigel keep us posted on performance please
Mid winter here so enjoy your summer riding while you can

I have found the only thing that propels you past a gaggle of Triumphs is a slippery track.....like last Sunday morning at Brands....

Taking that beauty to the track? So Fast Eddie, I have the stock exhaust reproductions on my bike as well and it's way too easy to scrape the pipes during spirited riding just on the road. How can you ride that bike on the track with those pipes? Don't they limit your lean angle too much for track riding?

Hobot · Jul 10, 2015

The big meaty front patch to make that brake rotor work is pleasing to me but cries out for an effective mudflap to shield the bright engine from road thrown grit. Could make snap on/off for conditions and place for reflectors and tussles.

I really enjoy most of your posts Nigel. But especially those concerning your own ride(s). It's almost as if I know your Commando inside and out (ceramic coatings and all). I'll be cheering for you from the distant sidelines. Take Command and don't let them Triumph. :lol:

Well... had a great old time. The bike behaved implacably despite repeated and thoroughly sound thrashings!

Managed to hunt down a few triples, but those properly sorted Rob North framed jobs were a bit different (of course, despite my previous bravado, I did already know this)!

Anyway, whilst the bike was good... And I really enjoyed it... etc... there's no point in beating about the bush to find long winded ways of saying this... It just ain't bloody fast enough !!

As the Dyno showed, power flattens abruptly just after 6000, up to which it pulls nice. On the track it is clear that its throwing power away somewhere and it should keep pulling strong to 7000+. I think this would make a big difference.

I'll play around with different velocity stacks and exhaust pipes on the Dyno soon (before Beezumph at Cadwell I hope, eh Sam). But in the winter I need to find more power somewhere, I already know the head is a bottleneck, just need to decide if / what else to look at...

Any ideas...?

" Any ideas ?"

Yep, buy a Trident :roll:

sam ( I'm sure that's what you expected)
Looks like you had a good time, surely that is the most important thing !

Any ETA on your new alloy barrels yet sir...?

Meggers, could help with a more extreme cam profile?

best get that Fullauto then.....

How much additional power is created thru the head change? I recall seeing at least one dyno chart with a Fullauto head fitted, and the curve looked very good. Has anyone done a before and after with just the head change from stock to Fullauto, same dyno?
I have done a lot of searching but it seems really accurate controlled dyno information is tough to find. People who are looking for higher performance tend to disassemble the engine then rebuild it with a multitude of modifications, then do the dyno testing. I can understand this as dyno testing is expensive as is engine assembly. No one wants to assemble the engine and test with one mod, disassemble then add second mod, repeat dyno test etc.
But the head is a big mod and it is possible someone has done testing with only that mod added?
I guess Jim Com stock is the most likely suspect, having designed the head and also having a dyno plus a knack for getting at the hard data.
