TK-Pipes (Terry Kelly) Au
Well over the last few weekends I finally got around to installing my Bill Blue 331cc big bore kit, kickstart kit and since I had to remove the pipe to do that I thought why the hell not install a pipe as well. I wanted an FMF, but with the current exchange rate, our AUD wouldnt make it worth buying overseas, and the local stealerships? Say no more... Then I stumbled across TK-Pipes in Trail Bike Adventure Mag:
http://tkpipes.com.au/
Quoted from his page,
"TK Pipes are built from quality materials including ceramic coated mild steel, stainless steel and sound deadening aluminium for the mufflers.
TK Pipes are designed to last the lifetime of the engine without repacking."
No repacking! Sounds good to me! Terry now only sells directly rather than through distributors in order to keep the costs down. So $460AUD and 3 days later:
The finish of this pipe is excellent. It has an end baffle restricting the sound to 94db at 4000rpm as per Australian requirements. It is pop riveted in place and can technically be removed although Terry informs me removing it makes no improvements to performance:
Much nicer on the optics vs the stock can! For comparison, the stock can weighed in at 3.95kg (8.7lb), the TK-P weighed 2.58kg (5.68lb):
More shots of the pipe mounted to follow...

Some pics of it mounted on the bike:
It sits pretty close to the rear fender, time will tell if the plastic melts or not:
Suggested jetting that came with the pipe is as follows:
- Raise the needle with washer 1.2mm
- Main jet 140
- Air screw 2.5 turns
- Pilot 42
- increase small hole in throttle slide to 2.8mm
Im actually booked in next week to put it on the dyno to check my fuelling, but since I changed the barrel to 331cc, Im not sure what jetting a stock 250 should use. At the moment Im running stock 132 main, a 40 pilot, 2.5 turns on the fuel screw, drilled the slide hole to 7/64ths as suggested by dynojet, filled the two top airholes in the Aus-spec slide. So far it runs a treat!
Sound is obviously louder than stock. At idle its a nice tone, low burble. Up to 4500rpm or so its quite mellow, but crack the throttle and it lets all the cars around me know Im there!
So far really liking this pipe and with Bill Blues kit and carb mods this bike is chalk and cheese compared to before. Very happy with it. Will keep you all posted on the dyno results next week.

Just a tip if you're worried about the proximity of the can to the fender:
My 2 Brother's M7 came with a spacer to prevent the muffler can from being too close to the rear fender.
You should be able to locate a slightly longer bolt (say 3/8" longer) and then use a spare nut in between the muffler mount and the part on the frame if connects to in order to space it out a bit from the fender.

Yeah I was considering putting a rubber grommet in there for 2 reasons, 1 to give more space between the fender and second to dampen some vibration. There is a slight increase in vibration from the big bore kit, kinda buzzes the seat as well as the rest of the bike. Not sure if any of the vibration comes through the pipe bolted onto the frame near the seat. Will find out.

hey Gany,
I'm in Melbourne too. Like the look of your bike. I think I settled on the 140 main and 40 pilot, needle on 1st or 2nd clip from memory.
I put an FCR on my 331 KLX, give me a yell if you'd like a look one day.
