I just bought from NewBonneville the Thunderbike Scrambler pipes and with some adjustment (did not exactly fit to the frame) it came on. Anyhow, they sound amazingly cool. Deep and punky sound (maybe slightly too loud). The people at NewBonneville say that it does not need any jet adjustment. I'm little worried... does anybody know better?

Cheers,

If they needed a major rejet,nobody would know better than Brent at NewBonnie or Thunderbike themselves.A bit of fine tuning,jet wise,is nearly always the case though.Order a couple sizes of main jet bigger and the allen screw carb kit and try a different,fatter jet if your concerned.You can`t hurt the bike too much by being a tad rich.

I met the guys from Thunderbike in Invercargill here in NZ a couple of months ago and subsequently corresponded with them: Jason said specifically that no re-jetting was required with these pipes; I'm saving up for them - cheers, Pat

Being that we do not have a Scrambler to test this out on our own, I trust fully Jason's at TBike's recommendation that rejetting is not required with their pipes.

I have Thunderbike cans on my Scrambler and my dealer fitted them, he also said that they did not require re-jetting, I specifically asked them to check because I had already added the K&N and removed snorkel. I just expected it would have to be done, but he explained to me that the bike are generally overjetted to begin with to cope with the restritions given to the engines at the factory. I guess this makes sense, anyway mine is running fantastic, and dont they sound GRRREEAATT!!!!! :-D

Thanks guys!

Highlly greatful for your adivses. My Scrambler runs great in low and high end, without jetting or fixing the air. So I guess I should llisten to her. Damm... they sound sweet!

These are the strap on pipes, called ThunderBike.

I had a slight problem getting them on, where it did not fit to the stock frame bracket, so I had to make some slight adjustments (extension bracket). Anyway, if anyone have had the same problem let me know please? I should go and take some pix of the fixing.

Muhahaha! I wish I had some spikes now... lot's of the white stuff now. Winter a bit too long here. Many do have spikes here, with smaller bikes.

If these are your pipes, you don't need a jetting change. This is per Jason Howcroft at Thunderbike. If you do any air box mods you'll have to re-jet for sure.

Yes, she's mine. The full exhaust from Thunderbike are quite nice. I've been happy with them so far. They make the bike sound similar to the Triumph short track bikes back in the day. Four wheel drivers know I'm near when she's at cruising speeds. :)

1. How cool are they against the leg?

2. Can you get your right leg in closer?

They are tucked in tighter than the stock exhaust. Between that and the ceramic coating, I've noticed a large reduction in heat on my right leg. Only thing I don't like, the right header is a about a 1/8 " away from the oil cooler.

I did rejet with my TOR's. I followed the Jenks tuning guide recommendation for the Scram. It was a bit lean and rough without. I can only assume that these pipes breath at least as easily as the TOR's. I have NOT touched my airbox, though.
As far as your pipes go:
Are they tucked in enough to wear synthetic riding pants? Can you tuck into the tank pads with your knees without any significant heat or contact?
Thanks

I'll be doing a bit of re-jetting myself... as I plan on a few airbox mods in the future.

As far as riding with synthetic pants, I can't say about heat build up on them. I can touch the tank pads without contacting the pipes, and I haven't noticed any increased heat while in this position. Here's a pic looking down on the pipes if it helps.
