Well i don't want to mislead, but i have had the insurance settlement come through on my downed Thruxton.
It came to $2000.00 of damage. I am fixing everything back to stock except the mufflers.
The left one got badley scrapped and they want $340 for a single stock one. So i thought the time had come. So i will make up the difference and get some predators. If anyone is interested in a right hand stock muffler for an 07 thruxton give me a shout. I would have preffered paying $525 and not hitting the pavement at 40mph, but every cloud has it's lineing i guess.
All the best John.

Well - I am glad your bike is coming online, but if you are putting preds on (great choice!) why not free up some ponies and throttle response, and remove the airbox while you're at it?

Just a thought! Haven't seen anyone regret it who's done it! I'm in the middle of it myself! :D

Hi Propforward
Pulling out the air box, doe's it make it a lot louder? Also doe's that mean the side covers come off and you see the pod filters? I have seen that look before, is that what you mean?
Thanks All the best John.

Well, it will make it a bit louder, but frankly your preds will be the bulk of that. It does mean going to pod filters of one tyoe or another, but these can be hid behind the side covers - once complete it is indistinguishable from stock. That's what I'm doing - keeping the stock look.

I haven't finished or road tested mine yet, but I have yet to find a post by someone who is unhappy after removing their airbox.

Just a thought - if you're rebuilding your bike - why not take the opportunity to get a few more ponies? :D

Each to their own though!

I guess the only thing stopping me is Money. I was thinking the next thing i need is a steering damper. I think the front feels so light as it is. I can do the air box removal later when funds allow. Do i need to rejet again after removing the air box? Or is it ok after the first rejetting with the predators?
Man i can't wait to hear the bike after they are on!
i keep watching you tube videos in the mean time:)
All the best John

although a steering damper is nice (i have a damper and a fork brace) if yo are going to put on predators you should probably do the bike justice and allow the bike to take advantage of the more free-flowing pipes by pulling out the airbox. the damper can come later.

unless you are hitting the twisties hard (like i was when i lived in colorado and rode the canyons all the time) the damper can wait. i agree you can feel the difference with the damper, but still think if you are doing preds the airbox should be done at the same time. just my 2 cents.

Ok guys i'm going to call the store tommorow and see how much extra it will be. Maybe i can do this if it's not to much:)
The girlfriend will never know!!

Pulling the airbox makes it a lot louder - for the rider - as there is a lot of sound absorbed in the airbox.

Hi Kiwi
I was wondering about that, because a buddy of mine
has a Toyota truck and he replaced the standard air filter set up with a after market open air filter. The one were there is no air box anymore, just the filter sitting in the open. It gave him more pickup power, but now the truck is quite a bit louder.
Instead of removing the airbox what if i just replaced the standard air filter with one of the KN filters. Will that give me better performance without the noise?
All the best John

If I could have another bike it would be a Thruxton. So congratulations on a fine choice of ride.
I went through the airbox / pipes exercise on my Speedmaster. I was surprised at the noise coming from the pod filters. I think it only made it noisier for the rider.
If I were to do it again I would opt for leaving the airbox and fitting a high flow air filter, and a good set of pipes. Then I would book a session with a Dyno specialist. I did this with my Speedy and we did 5 runs before it was as good as it could be.
At the end of the day its a Thruxton, with that wonderful parallel twin sound made by Triumph. Its never going to do 150 m.p.h. but it will perform well enough if you jet it out correctly after completing your mods.
Just my humble opinion. KT

I appreciate the input. I am a little concerned about waking the neighbours early in the morning. I suppose the predators will do that anyway. Do you still have the speedmaster?
I was looking at those and the America when i was searching for a new bike. How do you like it?

All the bast John

The America is a bit shiny for me. But both the America and the Speedy are very easy and forgiving to ride. With the right pipes ( non stock ) they sound great. Just pipes alone give them a bit more oomph. The later ones with the PI seem to require a re-tune if you do the pipes. But if you have a carbie one you should really put it on a Dyno and get it running right.
As for waking the neighbour’s....well I can’t sneak home no matter how light I am on the throttle. We have an old lady beside us. She loves the bike. When she was younger she worked at a Triumph Dealership. The shop boys used to make her sit on the bike backwards and they would do laps around the block. Ha Ha.

In the battle between your pipes and airbox removal it will definitely be the pipes that wake the neighbors:D! I have done both on my bike, to me the sound of the pods is kinda cool, it's not been an obnoxious sound.

Hey John - Glad to hear you're close to being back to normal (bike-wise at least!). I have the preds & K&N's - there's no comparison to stock performance or sound-wise, but you'll get the noise with the preds with or without removing the airbox, but to take advantage of the extra power (about 9-10 bhp) you really have to remove the airbox and go with some free-flowing filters. I've been trying not to wake my neighbors too but I think my previous 2000 Mustang GT with the glass packed cherry bombs was louder!:D
Anyway that's my 2c!
Cheers
Steve

Hi Steve
Nice to see you back. I hope your trip went as well as can be expected, under the circumstances.
It' more a money thing right now with the airbox. With Christmas coming it's a bit tight. I may go that way in the new year, hopefully work will pick up to. If i did it later would it require rejetting again?
Did you get the pix i sent you?
The old shoulder is still very stiff, i can't move it that well without pain. Sleeping is a difficult too but it is getting better. I have been told by the Doc my collar bone will remain pokeing up, unless i have surgery. It's called a acromioclavicular seperation, what a mouth full i should get full motion back eventually.
I can't wait to get the bike back. It should be done by mid next week. Ride safe
All the best John.

Hi John
I may be wrong here :confused: (anybody? feel free to condradict me on this one) but if there is no change to the airbox then there's no change to the air going thru the carbs and therefore there's no need to change the jets until you change/remove the airbox. If you changed the jets then all you'd be doing is enriching the fuel mixture - you just burn more fuel really!
A simple & cheaper solution in the interim may be to remove the snorkel & put a bellmouth on the opening which would allow more airflow - you might have to go up a little on the jets then - There's another good detailed thread on jets & set up with airbox/exhausts etc have a look it and see if there's a recommended jet setup for no snorkel
Cheers
Steve
PS Got thie pics - I'll send you a PM over the weekend
