The cell phone apps are useful for same bike, same environmental conditions, same rider comparisons, not accurate times. However multiple runs prove they are pretty consistent within their limits.
This week I re-installed my shorty pipes with a different type of DB killer and came away with some pretty good results. I decreased my 0-60 times to 4.1 seconds. The pipes are loud but don't hurt my ears with the DB killers. they are the perforated hole type as compared to the ones I had before that have mechanical baffles protruding into the pipe.

I've installed the Xpipe decat and the Booster Plug from Adventure Designs. I've noticed very little difference. Not sure if it's faster or not. Your iphone accelerometer and my seat of the pants accelerometer seem to dissagree. Given the chance, I doubt I would do it agin. The difference may be in bikes. Mine is a US spec bike that had pretty good fueling as a stock bike with the cat installed. I've read that the Euro spec bikes have low speed fueling problems, (probably too lean). Maybe I was trying to fix something that wasn't broken. Sure would like to try a good cam.

Mine is Euro 4 spec, the mufflers have a physical baffle in them, so that's one difference. US spec cans are straight through. If you have not, also remove the snorkel and its' gasket. The CAT is very restrictive, adding an X-pipe should release 3-4 HP mostly at the top end of the RPM range. Of course all X -pipes are not created equal, and debates rage on other forums as to which one is "best". also it is very important you do the ECU reset after every mod.

adding an X-pipe should release 3-4 HP mostly at the top end of the RPM range.........
I agree with you when you said “adding an X-pipe should release 3-4 HP mostly at the top end of the RPM range”. On most other bikes it would, but most other bikes don’t have a restrictor cam.

I agree with Tec Bike Parts after they had fitted an Xpipe-decat, mufflers, and Replaced the air filter and found almost no difference to the top end power.

The mods that you and I have done may have increased the low end and mid range power a tiny amount. The cam prevents improvements to top end power.....Again, I’m speaking of US spec Street twins.

Many follow the advice of Stewart Fillingham in his videos and take what he says as gospel. He’s A charming guy and comes across very authoritative. I’ve noticed inconsistencies in what he says. I think he might be just a little naïve and a very good salesman for Motone Customs.

I agree the cam is restrictive, but there have been dyno runs showing some increases as I mentioned without a cam replacement (HP wise). regardless I have numbers indicating my "set up" has decreased 0-60 times by a round 6-9/10s of a second. whether I can say it is due to intake mods, de-cat, 44 tooth sprocket or my self designed mufflers, I don't know. There is a wealth of info on other forums actually, but many shills hawking products as well, The MeerKat crew as an example. Stuart is a nice man, but he is more or less an agent for Motone.
My mid range to top end power band is seemingly stronger, and without a proper timed distance or dyno run it can't be stated unequivocally. But as my Street twin used to die at higher rpms, it now revs nicely from low end to rev limit without gaps or flat spots. I can guess my sprocket has some to do with the low end.

There are about 4-5 guys that have installed Raisch cams, all lost low end torque and gained 10-15 HP at the top, which has been made possible in part by raising the rev limit to 7,500 RPM. using the same cell phone app I use one got a zero to 60 @ 3.6 seconds which is just 5/10s under my low cost mods, I see no need to go to the expense of a cam for such small top end gains where I ride. One guy installed the Raisch cam and said he saw little initial improvement, not sure what was up with that. The real issues with the street twin are not only the cam but the smaller valves, single throttle body and porting. by the time you correct all that you have a Thruxton.

In the end for me it is less about dyno numbers and 0-60 times, but how the bike responds to throttle at various rpms in each gear. You absolutely right about trying to compare models from different markets, there are at least 6 different tunes and several hardware differences from market to market.
Which x pipe did you buy out of curiosity?

The Tech Bike X pipe.

 

[RHB]

tec is one of the better ones. and George claims in his x pipe video real gains of some undisclosed sort, so depends on which of his videos you watch I guess.

TEC just announced their cam is in production again and ready for ordering. Note that they are only for 2016 and earlier models

The cams are back on! Please read full email for info on how to get one
We had previously announced that we were ending the development on the cams for some of the new water-cooled Triumph models. We always hoped to be able to get the product out to our loyal customers but we were receiving such a huge number of enquiries on a daily basis about the cams that it was hindering us from getting our work done. Without knowing when they would be ready we could only give rough deadlines for their completion which meant frustration all round when these deadlines were missed. As such, we decided to put an official pause to the development until we were sure they were 100% ready.

After a lot more R&D into the cams we have now got a batch that are fully tested and ready to sell. We have tested them in our own bikes and are extremely pleased with the performance they are putting out. After thorough quality testing there have been no issues caused in any of the bikes.

The cams are manufactured in the UK and will have a full manufacturer backed warranty. We will also be releasing a video showing how to install the cam.

This batch of cams will only fit WATER-COOLED 900cc models of the T100, Street Twin & Street Cup manufactured in 2015/2016. It will NOT fit any other models or years. We are going to be making a cam for the later water-cooled models including the Street Scrambler later in the year. We have a camshaft in development now for the 1200cc motors and is in the later stages of testing at the moment. These will be ready later this year, we will be making a big announcement when they are ready. If you are signed up to our mailing list, Facebook or Instagram you will not miss it.

​

Our first batch of cams are ready for sale
The cams are going to be sold for £360 including VAT. They will be sent via next day courier to UK, and courier to the rest of the world at our standard post rates.

Part of our research has lead us to find that this current batch of cams will only fit bikes with certain VIN numbers. The only bikes they will fit is certain bikes manufactured in 2015/2016.

The first batch of cams we have is very strictly limited in number. In order for it to be a fair distribution we have decided to sell them in a slightly different way. Please read the following instructions very carefully if you wish to buy one as it will be the ONLY way to get one. Please do not try phoning or emailing separately as we will not be selling them any other way than the below method. Please also read all of the below FAQs.

They will be sold on a first come first served basis. The way to register your interest will be to respond to the next email that we send out. Do NOT reply to this email about it, this will NOT count for entry.
The email will be sent on Tuesday 12th June at 18:00 6pm GMT. This will be automated by our mailing list operator so it may not be at the exact second. Have your VIN number ready and just respond to the email as soon as it arrives with your VIN number, bike model & year. You only need to send your VIN number with the model & year of your bike.

Again, the only models and years this cam will fit is 2015/2016 water-cooled 900cc T100, Street Twin & Street Cup. Do not bother emailing if you have any other year or model as it will not be entered as the cam will not fit.

The first responses with valid VIN numbers will receive an email from us about purchasing until we have sold out. If you miss any of the required information your entry will be ignored. We will be organising payment through PayPal invoicing. This means you can pay with PayPal or any major credit/debit card.

If you receive no response you have been unlucky or your VIN number is not valid for our cam, sorry about this.

Cams will be limited to 1 per order.

Good luck with your entry and we will announce via another email when we have another batch ready. This will be how future cams are sold so please watch for our emails. We will not be selling them directly via email or phone enquiries. Please make sure you are on the mailing list if you wish to find out updates about the cams and our other new parts.​

Didn't know Street Twins were produced in 2015. Mine's a 2017.

After I removed the snorkle the bike seemed to wake up. I'm now sure it's running stronger. I'm using a Tec Bike Decat Xpipe, a Booster plug and removed the very small diameter snorkle. This skeptic is finally convinced.

Mine too 2017, its an odd requirement, Raisch has no such limitation, how different can the cams be?

Have now got my cam from tec bike. Had to send them my VIN No. As they say that they are not all the same. I have ordered the few bits that you need to fit and cant wait to try it out.

Anxious to hear the results...

Are you doing the work youself, would love to see some pictures of you install, and of course performance results. Stock bike ? or modified with de-Cat, mufflers etc.?
