Ok what are billet bolts ?, are they better than std grade 8 bolts, how many can you get out of a billet?

lookin' sexy !!
It (and you) should be down here this weekend for the Grand Prix !!

they are extra strength anodised {coloured} boths...they are realy strong and dont bur

their hard to get in auckland so i wouldnt think you can get them in christchurch.

Why heatwrap? Looks pretty good. You need to add a scott oiler for the pirellis though

whats a scott oiler?? and heat wrap heats the pipe up so it flows the gases more quickly......

I've heard that before for older two strokes, but I'm not sure it would have any effect on a fourstroke. Isn't there a chance of overheating at the exhaust port? Meh, you can be the test rat, I might do it on my cb if it works for you... A scott oiler oils your chain, I was just being a smartass. Unless you want to keep your tires nice and lubricated, of course... Could make things interesting!

just an aside should of course only use steel or Ti on brake calliper or MC mounts.

Heat wrapped exhausts are used to protect other items around the exhaust from excessive heat or on an exhaust inside a fairing to reduce the heat contained within the fairing....expecially a concern at low around town speeds.

On a two stroke they keep the exhaust hot and help prevent oiling up.

On a 4 stroke where radiated heat is not a concern, your are better off (very slightly) to allow the pipes/exhaust gasses to cool..making the gasses denser, there by travelling at a slower speed meeting less resistance, there fore less back pressure, and better engine breathing...but as I said, it is a miniscule increment.

On a turboed engine, insulating between the echaust port and the turbo improves turbo effeciency. There is also a lot more heat in a turboed exhaust that needs to be contained, to protect other components from radiated heat ....

Thats my dribble for the day....

dIFFERENT SCHOOL...YOUR THOUGHTS ON LAGGING A 2 STROKE EXHAUST?

The idea of laggnig a spannie was to keep a consistency of heat (& thus tuning frequency due to wave speed) rather than cool it more with wind (lowering revs tuned to) at speed, but there are good reasons not to as well.

But this will have no effect on stopping it oil up, that is purely jetting related.

I new there was a science to expansion chamber design that had a big affect on 2 stroke performance but would never have considered it to be to that degree...more info on good reasons not to?

It's in the TZ350's ESE works tuner thread... along with HEAPS of other info.
