Hi SD

Santa brought me a pair of those nice mufflers, any tip on fitting?

Mike

Hi Mike....now there's a good Santa!

Fitting tips.
Some brass shim stock rapped around the pipes to get a tight fit with the mufflers.
Throw away the bolts and brackets that they come with.
Only able to use one bolt to secure the muffler to the standard muffler bracket on the bike.
Modified a bolt head by welding "wings" on the hex head so that it would not spin in the mufflers mounting slot.
Used locktite on the bolt.

Tuning tips.
As GP suggested a plug check to confirm the mixture. Mine is rich in the 3000 to 4000 range, so I,m going to lower the needles one notch sometime this week to sort it.

You are going to love the extra go over 4000.......and the music

Just got back from a holiday in New Zealand with two of my teenage kids. Conned me into a tandem sky dive from 15,000 ft....awesome. Travelling vertically down at 200 kph with only a rag for a brake really gets the adrenaline going. Think I'll stick with horizontal velocity and disc brakes.

Looking forward to your comments after you fit the Dunstalls.

My wyfe and I did that a couple of years ago, after our youngest daughter turned 3. What a HOOT!

15 minutes to get to altitude, 15 seconds of free fall, and about 5 minutes under the canopy. WAY too short.

I wanted to go twice as high, then fall three times as far before popping the chute, but they looked at me funny.

 

[Sea Dog]

Good on you Paul. Brave wife!

15,000 ft gave a minute of free fall which seemed forever and scute opened at 4,000 ft. Like you, I would do it again. Had to use oxygen on the way up.

 

[mikechev]

Ummmmmm......

1. Take the old ones off.

2. Put the new ones on.

3. Enjoy!

(actually, you might want to do a plug chop / check, to see if you need to adjust the carbs a bit for cleanest running)

SD, you should give up your day job and become a full time technical advisor on the site


I have fitted one and thought the mounting bracket that came with them was not man enough? hence the question. I was going to make some but if you have been riding with supplied brackets and they are holding up OK that will do for me.

Did the service after my 1st 300 miles, torqued the head down as you suggested and i was surprised how much it needed. Replaced the rocker cover gaskets some i made The British Spares one hadn't arrived yet) this fixed the weeping fine. Unfortunately the torquing down of the head must have tested one of the push rod tube too much and i now have new oil leak... that one will have to wait until winter.

Might have some news on how to get the throttle action a bit lighter, not say anything until Iv'e tried it.

Cheers

Yep, we only got to go to 10,000 ft for 1st jump ever. At least we got Sally's on video, set to the tune "She moves in mysterious ways", pretty good videography.

Yup, the bolts and brackets are a no brainer, good tip about the brass shim i will need to get some of that. I would prefer have the 2 bolts holding the muffler, i think i have an old pair of T140 muffler brackets that i could adapt. I need to have a look at one of the carbs as it's now (occasionally ) started to get a sticky float an the fuel pees out of the overflow when turned on. A sharp tap with the soft end of a screw driver fixes it, but i've now noticed a slight surging at constant speeds (30-50mph). this might be related to the sticky float/valve? Progress update to follow, given the amount of rain right now i might get it all done as i won't be riding.

What is with the jumping out of planes? isn't living in MacKay scary enough

You 're not wrong. Aggressive testosterone charged miners in their 300 + kilowatt V8 utes is very scary. They seem to be culling themselves off on the highway to the mines on a regular basis. In town, its a race track and using indicators optional. As for the locals....look back 20 years plus an hour for daylight saving.

Ahh Mike. Another technical tinkerer on the site. Throttle mod has me intrigued. SD

Check this out SD http://www.canbeseen.com/10 i got the "606" ones and just fitted them BIG DIFFERENCE ....

Mike,

Well researched. I like what you have found. Really pleased it has fixed the heavy throttle. The TSS will be a shear pleasure to ride. How's things going with the mufflers?

Santa's present was fitted today! I could not get any new clamps today but i found the original ones from my Thruxton (has Staintunes fitted now). They are SS so not as bright as the mufflers but look OK and gripped the pipe fine. I modified an old pair of muffler hanger brackets to take a bigger bolt, it feels strong but a only a few rides will tell.

Removed the baffles and took of the wadding as you suggested, i kept it intact incase i need to refit it. I was really tossing up between getting the Peashooters and the Dunstalls, but now seeing them fitted they really suit the bike. Excellent choice SD.

Some sound and vision - i hope! apologies for the lack of editing on the video and not cleaning the finger marks of the pipes before the photo shoot

Just need some time for a ride and plug chop (thanks for the tip GP), i reckon i will be doing a bit of carb work on her soon.

Interesting oil leak. The same happened to mine (lower exhaust push rod tube O ring) and I will need to address it at some stage. Perhaps this wet season will motivate me.

Thanks for the photos Mike. Springs and mufflers look great. Didn't get the sound, but that may be the computer I'm using at the moment.

Very nice of Santa be sure to let us know how they feel

 

[mikechev]

Sorry forgot to add the video, try again.

 

[CarlS]

Great posts, Mike. Those look really good.

 

[grandpaul]

Too bad there are so many other projects in the queue before I get to the TSS. These are great tips.

Oh well, I'll just have to keep enjoying it just as it is...

This is true for me also GP, just the TSS is the favourite child at the moment

Dropped the needles down to the lowest notch. Definite improvement in the 3500 to 4000 rpm range, however rain stopped play and could not do a plug chop to read the mixture.

Mike. Phil from Norside Motorcycles says g'day. Really helpful bloke. One of natures true gentlemen.

Damm, this means my identity has been reviled and you now know what i do for a living... I'm one of the good guys honestly

Yes, Phil is top bloke, a rarity in my work unfortunately.

just to clarify, lowest notch is the top one? leaning out the fuel?
