Will keep the list updated as I progress. After Sandy now we have a nor'easter to deal with! Hope it won't cause too much havoc.

Argo the issue is not finding something that will fit, it is making something that is optimized for that particular engine.

Fitted 50mm RS Mikuni velocity stacks, with foam socks to my stock CV carbs, previous to this had a modified airbox, when I fitted the TEC 2 into 1, I lost midrange and bottom end power, 3.5K-5K, the 50 mm stacks have cured this loss of midrange, have 70mm stacks to try, also used only the short 865cc intake manifolds without the black plastic spacer.

Hi guys, just joined the group and am willing to answer any questions regarding the possibly forthcoming velocity stack/filter mount for the Triumph...............

BLAH, BLAH, BLAH! Yea, we'll see. I've heard all this crap before and so have allot of others. Normally nothing comes to flourishion (fruition; just for eddie) and this is no exception.
You need to go away, do what's necessary and come back with a product available before you start shooting your mouth off or sending your minion in your place. If it's such a great concept, then tell me why the premier Triumph tuner in the country (TPUSA) isn't concerned with it or developed a similar kit? I suspect, it's not worth the effort.
Mind you, before you intend to join the discussion and advertising your product, you'd better make yourself familiar with the AUP's regarding such. Also, don't provide your own data, use an independent who will verify the data you provide.
Actions speak louder than words. You've provided absolutely no data for the Triumph Twins and this is the subject at hand. Not your buddies KTM, which is a completely different engine and tune configuration. Until you produce a viable product, your the armchair cowboy, haus.
I'm not going to get into a push come to shove regarding my knowledge vs. yours, as you've already admitted your lack with Triumph twins. There are plenty of savvy Triumph twin builders here, you need to back off and come with something proven, especially before you start throwing around dollar & hp figures for something that doesn't even exist, except in your mind.
Problem you're going to have in development is; modifications make differences in tune levels. You can't produce, one size fit's all. Different tune levels require, different stack heights and the stack heights, will determine the hp/tq curve over the RPM range and where. It works the same with Ducati's, as any other motorcycle.
Until you have something available, I'll remain rightfully skeptical. It's all just a pipe dream.

sHANEDUC,
You need half an hour on a bouncy castle. He's going to do his own research and if it works then he will sell it. We can all do our own tests if need be, you need to dyno setup the carbs anyway so this would be easy. Please get off the high horse and take a chill pill.
Chris.

I hear where you're coming from Agro...for about $35 per pair of velocity stacks and $100 of dyno time, I can test all 4 of the RS velocity stack lengths for my machine for less than $250 and have a induction length tuned to my motor's exhaust/cam timing.
My personal experience reflects your result, which was dialing in the tuned intake length ws beneficial in backfilling a hole in the midrange. It did nothing for me up top on either the CVKs or on the CR carbs.
Regards,
--Rich
