Throttle bodies rebore

- 05th July 2017

I took the decision to spend money on developing my scrambler instead of a new one as I like it so much. I have nearly all the upgrades on this site, and every step has given me the boost I was after. But the bodies being re-bored as made a hell of a jump in the engine and after a 500 hundred mile run I love the new engine and how it performed. Really worth going for.10/10

TB39R Throttle Bodies

- 15th February 2016

All I can say is wow! I installed these with TTP Tune 15 and my Bonnie has come alive.

The process was easy as can be. I decided to have my own throttle bodies sent back to me. This took approximately 3 weeks once they received them. During that time, Mike was kind enough to let me know they received them and kept me informed throughout the process.

Once I got them back, I couldn't believe at how nicely they were put together. Looked like they came out of the factory, only with a new coat of black paint.

As noted in the letter attached to my shipment, the TPS sensor is going to need to be adjusted. This is a fairly simple process if you have a TUNEECU type program or the Triumph diagnostic tune. It comes attached to the throttle bodies but you'll want to verify it before you load the tune. You are also going to want to check to see if your throttle bodies are balanced. Mine were and I didn't have to worry about it.

Once installed on my Bonnie, I couldn't stop grinning. I have Gasser Customs Exhaust, BC Air Box Removal, SAI/AI Removal and stock 865 Cams. These throttle bodies gave me the "by the seat of my pants" feeling. I couldnt believe the difference. If you read on the Triumph forums, there are a few who say these Throttle bodies didn't make a difference. I can safely say, I have felt a difference. There is more torque and stronger pull through the rev range.

I will eventually be upgrading my CAMS, but for now I am extremely content.

I would recommend this service to anyone who wants to give their Triumph a little extra spunk. If you have any concerns, I'd shoot Mike an email. The customer service is top notch!

Thanks again!

Finally got my ported & flowed TTP throttle body from Mike...installed and very happy with the significant urgency to pile on power when throttle is twisted open. The service from Mike is excellent !!
Combined with Tune 4 remap, Breath, Dominator exhaust, Pretech 6pot brakes, Wilber suspension both Thruxton finally rides that much closer to its true potential. Thanks TTP & Mike !

Quality that really works

- 02nd June 2013

It's a pleasure to see work that has obviously been done by someone who takes pride in what they do, I wanted to sit them on the shelf and just admire the workmanship.

In use, with a few other mods, they have proven to be as effective as claimed, right through the rev range.

Excellent back up and advice with the mapping just puts icing on the cake.

Finally got them fitted with the new airbox eliminator. Installed the tune that Mike recommended. Off for a test ride - you beauti! What a diffence - riding it now for several weeks. Biggest difference besides flying at the higher revs is the low down grunt.

Excellent product, the best service (thanks Mike) - just do it - you'll be a happy budgie

Great Performance Upgrade

- 13th June 2011

The TB39R throttle bodies delivered a genuinely noticeable power increase with the bike feeling especially lively higher up in the rev range. Low RPM torque also felt healthier.

The accompanying ECU map has obviously had a lot of dyno time invested into its development- its very smooth and power delivery is faultless. Most noticeable is the lack of throttle snatch and on/off jerkyness that was present with the Arrow 2-2 Map, this has hugely improved the drivability at low speeds and made the bike much more enjoyable to ride in and around town.

Triumph Twin Power were a pleasure to deal with- emails were answered very promptly and there was plenty of useful advice on hand when required.

Thanks Mike!
