Thanks Fred, but wouldn't going to the next size jet (62.5) do a similar thing as putting a washer on there? If 65 is too rich and 60 lean, 62.5 should be about right (in theory at least).

I don't know, I just do what Buddha tells me...

Thanks for the input. I've got a 20 pilot, 62.5 mid and 142.5 main on the way. Will try that and see how it goes. My gut feel is that will be pretty close to spot on considering the way it is now. Possibly might need to go up 1 step to 145 main but I'll try the 20/62.5/142.5 first and see how that goes. Hopefully bits will be here tomorrow so I can do it over the weekend.

Yes i do. Can is $550 from memory so the pipes for $700 odd is a very good price.

I got my Jardine full system with polished can from the US shipped to OZ for less than $500. With the Aussie dollar dropping a tad lately it might be a touch more but worth checking out.

What did they charge for shipping? $336.95 USD is a good price, wish I'd seen that one a month ago. Did you get the QMI (quiet module) ? How loud is the exhaust without QMI? According to the site it's over 100 decibels which is pretty loud!

Cheers drewbytes and galahs, you've given much food for thought. i was planning on selling my GS when i was off my p's and moving to a bigger bike, but after searhing through this site i'v changed my mind. . .the gs stays

Hey galahs, would you please be able to post a pic of your GS with the Jardine exhaust, it looks good on the website, but nothing compares to seeing it on the bike, cheers

Yeah its pretty loud. Probably too loud if you do a lot of touring the quiet module would be a worthy investment.
It does have a nice burble however, and around town it really rumbles and makes the bike sound tough.  :thumb:

Galahs, cheers for the pics mate,i'm def guna invest in the full system, it looks great,and everyone says it sounds good. Only problem is that with the AU$ so bad now it'll cost me $629AU, so theres a downside. Thanks again for all the help, i'll post pictures of mine with the system on when i get the chance  :)

Put the new jets in just now, and the good news (for me) is that it only took 1 hour from go to whoa. You don't even need to take the carbs off the bike. I only removed the tank and undid the 3 fuel lines, unclipped the carbs from the engine and rotated them upwards so I had access to the bottom where the jets are. So no removing various lines etc. Very easy.

I'll report back over next few days how it feels with the 20/62.5/142.5 jets.

Hey Galahs, i'v ordered the Jardine system for my GS and am now waiting for it to get here. Just a quick question, how long did it take for your order take to get from the US to Aus???

galahs

Just over 1 week mate. It was very quick.

Yeah I did my jets by just turning the carbs over too. Its easy that way. My only problem was my float bowl screws didn't come out easily. Othewr than that, its a simple job.

Helmet27

Cheers Galahs, now i gotta go out and get a set of K&N filters and the same jets as yours plus do a "fenderectomy" and get new indicators. And when i finish that i'll have to sit around and wait for the exhaust to get here  :cry:

It's in the Wiki. If you want twin K&N then it's RN-0800. Probably around $80 each from a car parts store.

Thanks for the info drewbytes, i'll go searching tomorrow for them and some jets  :) thanks again

An alternative to individual pods you can get a K&N Lunchbox airfilter. Its basically a large pod filter with two openings that fit onto both carbs.  Its part number is RU-2970 and is hard to get in Australia. Easier and cheaper to get from overseas (isn't everything!).
