Pipe heat

Black Knight · Post by **Black Knight** » Tue Dec 19, 2006 2:53 pm

I'm really new to this B< stuff so excude the dumb question.

I have a Lazer system fited to the bike.

The left hand pipe warms fairly quickly, the right, stays stone cold.
The right is working, just doesn't seem to heat easily.

Is this normal?

I'm guessing its just the way the down pipes run into the LHS can first??

FULL ENGINE SERVICE NEEDED QUICKLY! THROTTLE BALANCE OR PLUG, OR PLUG LEAD; POSSIBLY VALVES.

Have a look under the tail......... one can is straight through, the other has a T and an elbow on the upstream side.

It's a bit of a swiz - far better to fit a Staintunes.

(hang on.... are you talking about the header or the tailpipes?? I assumed cos you mentioned the make of exhaust that it was the tail. Surely it isn't running with only one cylinder firing??)

Oh, you meant silencer temperature. Dohh!

Yes, sorry wasn't very clear.

I meant the silencers under the seat.

The one which runs directly off the pipe heats up a lot quicker than the RHS one which looks almost like an extension.

It's all about the easier path for the hot gas. Obviously, when the gas flow increases, the back-pressure increases and more gas will go through the "restricted" can.

90mph run up the (private) motorway for 30 miles or so.

Get home - touch r/h pipe with hand: Mmm nice & toasty. Touch l/h pipe: Nurse!!!

Deduction? More gas goes out of left than right pipe.

You say that you have not taken the bike out yet but I presume that you have been running the bike stationary. Be careful with this as the engine has no cooling system (it requires the air to cool it and the oil down) and you don't want to over heat it.
I did this when I got the bike and was sorting out the throttle balances and before I knew it I could hear the oil bubbling like mad. I did take a long time doing the balancing as I had not done it before. In the end I took it to a mechanic in Bromley and he showed and explained to me how to do it - only balance one side to match the other, don't balance both. Only took him a few minutes. BTW he put a massive fan in front of the bike to cool it down as it was still cooking!

Thanks for that Joe, not something I had thought about.

I only had it on for 5 min or so just to keep the charge in the battery and feep things fluid. Its a pain in the jacksie really as the garage is away from my house and has no power supply so an optimate's not an option.

...I once had such a Laser cut in half ; and what looks from the outside as a T-pipe, is nothing more than...nothing...

...in the straight pipe (left side, if you look at it from above) these Laser guys had cut a tiny hole (and I mean a real TINY hole ; about 10 millimetre !!) for the right (again...; if you look at it from above) pipe and silencer...

...and because that hole is only this small ; most of the hot gas will leave through the left silencer...

...but after cutting away this T-section & 'some' welding it looked like this...(using both silencers now)

...different looks & sound...
