Tec cam

Howdy,

Recently had the Tec stick with lumps (cam) fitted to my 2018 Street.
Previously the bike had a mapping change by the dealer when the bike was new as i had the X pipe fitted at pre delivery. By dyno that was running rich across the rev range, dyno at a much later date.
Then i fitted Remus pipes, running without the baffles, then the dyno said that it was lean with slightly more torque but no change in HP. Fitted a BoosterPlug and seemed to fix it, the leanness and reduced the throttle roll off cackle? But no dyno run to confirm this.
Also have K&N filter installed.
After the debacle with the German cam, and heaps of stress and a return of the cam, I ordered the Tec cam.
All I can say is wow what a difference it makes. Probably only got about 500Ks on the new cam and had it fitted at the 10K kilometer servicing. Bike pulls better throughout the entire range above low end torque, possibly a tiny drop from the bottom but I also removed the snorkel at cam fitment, but wrapped in how much better it goes. Used to sort of slow down in acceleration around 120kph (top gear) now easily pulls to 140 and still feels like it will keep going but giving it a bit of a run in before I go balls to the wall/full loud.
As it doesn’t go asthmatic I am holding for longer in 2nd gear corners where as previously I would change up to third as it was running out of oomph although it really was a 2nd gear corner for my thinking and riding style. Now these definitely are 2nd gear corners.
I feel there is real need now to change the gearing to taller with the extra grunt, was thinking of 2 less teeth on the rear but it may be easier for me to get 1 more tooth on the front where I am situated.
Have access to a power commander and am wondering if it is worth going to the hassle of getting that sorted, a map then fine tuning on the dyno.
Currently, BoosterPlug, X pipe, Remus straight thru pipes, snorkel removed, K&N filter and the additional box thingy in the intake side with vacuum lines going to it, fitted here in Thailand, removed.
After fitting the cam and removing the snorkel there is a lot more burbling happening on throttle roll off than previous so maybe the BoosterPlug can’t fully adjust for the cam and all of the other mods. If I decide to fit the power commander will do a pre and post PC run to check on fuel air ratios, Tq and HP also, in the current configuration.
If I do another dyno will get the previous run sheets for comparison.

Am I missing something about people quoting exact RPMs from the street, are people using smart phone ap or an after market tacho?

Am keen to hear from anyone who had one of the 900 liquid cooled engines, Twin or Scrambler, with a cam fitted and then moved onto the Speed to get their opinion on the actual difference in real world feel. There is no substitute for cubes and another 300cc’s must make a difference and then of course there is that 6th gear and twin disc brakes.
Have a few reservations regarding the Speed over the Street, considerable loss selling Street to get Speed and seat height is real issue for me at 155cm/5’2” ish. Additionally i have a 765 for speed and high end brakes and suspension. Would love the extra cubes in the 1200 and the 6 speed box, tacho and twin 4 pot discs but the price difference at the moment is something i don’t think i could live with, maybe if a demo comes up at the right price or after a year or so there should be some low ks SH bikes floating around where some other poor bugger has worn that big initial loss.

Thanks.

So we ordered up a new Brembo radial master cylinder from the Street Triple R and will fit that to help with stopping, a new black lever to match for the clutch, and I just ordered up the progressive spring and preload adjuster kit from TEC USA... Oh, and the X-Pipe. So it will breath a bit better, be a lot louder, stop better and handle better. I already have the Fox shocks on the rear, so the forks being stiffer will help.
Be happy to hear any updates about the performance difference in braking by fitting a good quality M/Cyl. Interesting to see how that cylinder goes as it was designed to move 8 pistons as opposed to two.
Previously fitted EBC HH pads which helped but i still feel the braking is woefully inadequate prior to fitting a cam let alone after.

I will report back, parts should be here this week. X-Pipe is going on this week as well. Hoping that the bike doesn't run too lean with the X-pipe, debaffled stock cans, K&N air filter with snorkel removed, etc...

Some say the dealer has an off road map, others say it doesn't and that all they do is the "12 minute tune"...

Thoughts on that?

Speed Twin and Thruxton are a different class.

However. For $9k I have performance that I love and more like a more expensive bike.

I looked at a speed twin but it’s too tall for me. I am very short.

Additionally, if I get another bike, probably a street triple (LRH). Have a classic type and a sport modern.

Thank you for the distinction. I should have clarified.
Perfect pairing a triple and a twin. That's what I've done, never gets old.

Possibly a BoosterPlug?

Was reading on another thread that the 12 minute tune at idle on the side stand in neutral doesn't work as the bike has to be in gear and clutch out for the learning to happen but the ECU learns as you are riding. But it will still only adjust to the lean OEM figures anyway. IMO better to fit a booster plug or power commander but the power commander is a lot more expensive and then requires dyno time, or a skilled operator with laptop and experience to fine tune it.

My oops if your bike is 2019 model as it will have one 4 pot caliper not one 2 pot caliper as my 2018 model.
Priced the 4 piston caliper from Triumph for 2019 model caliper and obviously have a high gold content by the Triumph price lol. Nearly as much, 75-80%, of a pair of Brembo M4 calipers!
Also think that the mounting bolt distance is different as my 2018 model is 80mm.

I was told by George that if you do exhaust. especially CAT delete, you should either run his plug kit, or better yet, George say the V&H tune from Triumph works great for running rich with an exhaust, even his rebel 2-1.

My dealer said they have stock and Vance & Hines (V&H) and put the V&H tune on with all exhausts, mirroring what George at TEC said.

Had my 500 miles post Cam install oil change today. Everything looks good and Maggie is running great!

The oil apparently looked good and there were no noticeable metal pieces, etc.

Test rode the 19 Street Twin yesterday,
So now understand about the tahco figures mentioned before, hadn't kept abreast of all the differences from 18 to 19 models, oops. The digital tacho is so much better than no tacho on the 18 model.
From memory the bike seemed to have a bit more go in standard trim than the 18 model and the gearbox was definitely much smoother than the 18 model.
Wanted to feel the braking difference from my 2 pot caliper to one 4 pot caliper and although there was a noticeable difference it wasn't as much as i had hoped, but maybe the brake wasn't fully beaded in on the demo bike as it only had a few hundred kilometers on the bike.

This may be getting to off topic for the subject matter here and i may be better starting a separate post about brakes.
Rechecked and they 2019 street twin caliper mounting bolts are 65mm apart, same as the Speed Twin but the 2018 model with 2 pot calipers mounting bolts are 80mm apart, same as the T100/120 which are 2 pot calipers.
So there is no direct bolt up option that i can see for the 4 pot calipers to the 18 model. Web research found the 65mm and 40mm P4 type calipers, Speed twin and 2019 street twin type, so these would need a mounting bracket to be manufactured to fit 2018 street or T series.

Would have thought that if there were any metal bits they would have been trapped within the oil filter as that is its job.
