aggghh!!

dropped a bit of a clanger here - finally got the two into one quietened down sufficiently with a db killer - the pipe really makes a difference to the way the bike revs, i found myself hitting the rev limiter on a couple of occasions yesterday which i have never done before


all was good until i sat down and looked at the bike last night (you know that 'job well done', 'cake in hand' feeling) when i noticed how much higher the new pipe kicks up - this means that my Givi throwovers will be resting on the pipe on the right hand side agggh!!

this may be a daft question but just how hot does the can get? i am sure i have followed bikes with the pannier touching the pipe - but not really taken much notice - anybody else had this problem / any solutions?

i wanna go off to Wales this weekend but dont want to be depositing my smalls in a gooey plastic mess as i go!!

cheers,

stu

sorry for being so daft but what does the following mean:

"....finally got the two into one quietened down sufficiently with a db killer - the pipe really makes a difference to the way the bike revs, i found myself hitting the rev limiter on a couple of occasions yesterday which i have never done before"

I am guessing that u made the 2 pipes into one using a single exhust? can u pls give pictures and or links where and how this can be purchased /done?

Has any segnificant weight been saved?

and why would this improve performance?

He's changed his standard exhaust for a 2-1 system (single can instead of one either side), but it was noisy, so has used a decibel killer (DB Killer) to reduce the volume.

Something Like This

depends on the can
some do get hot, the more 'legal' they are often the cooler they are as theres more wadding to spread the heat

touch it with a carrier bag, if that melts then it will be hot enough to damage your panniers

Remember watchin Spud shed his pants and towel down a dual carriageway for the very same reason.

tnx - I am very interested in how this 2-1 after market set up looks like - do u have any links for our bikes?

ow ow ow ow ow!

no really - thats very hot and my hand hurts now - what a tit!

i think i have the answer - if its hot enough to cause this much pain then it will melt through my panniers

i let the bike run up until the fan kicked in so fairly hot - i have managed to hitch the panniers up by means of a bungee and by slinging two of the fasteners over the top of the seat not underneath it - this gives me a about 10 mm clearance above the pipe. The odd thing is that the highest point of the pipe (right where it is closest to the pannier) stays relatively cool. (hence me burning my hand - the difference in temperature a few mill down the pipe is incredible)

I will pop some pics on in a bit

Can you put some packing on the seat under the straps to raise the bags up a bit ?

[wicklamulla]

still too close as the zorst gasses will toast it.

[Migs]

OK, bend the pipe down before the can and add a spacer at the mounting.

im thinking along those lines - just figuring out how to do that now - there is a fair bit of "give" in the pipe and i could probably gain a few mill that way

not sure how the random pic got in there - wrong copy and paste that could been embarassing!!

[dapleb]

Oid be more worried about melting that giant Malteser!!!

it will bounce up and down and melt

i used soldering heat matts to cover the bottom of my old set of panniers
but thats not as easy with soft luggage

[Daveb]

why not strap them onto the tail pack.

didn't someone on here have luggage fitted to the front of the bike, along side the fairings

I wonder if it's possible to strap the plumbers mat around the can, maybe use a large jubleeclip or 2 ?

[newstu]

just in case - i have made a sort of heatshield for the bottom of the pannier - a la Blue Peter stylee except the tape is foil tape that i use for acoustic baffles for work.

Which part of this Lovelly country are you visiting? its going to be a good weekend down south well saturday http://news.bbc.co.u...er/forecast/380

found heatshield tape, not cheap

Thermal Velocity have integrated aerospace grade high temperature resistant fabrics with the latest coating and finishing technology to produce advanced easy to apply performance automotive heat shield tapes.


Heat Shield tapes are used in applications to protect painted surfaces, plastic parts or any other component from the damaging effects of radiant heat.
