Tell me about dyno setups, and dynojet kits.

[Tristan.]

The CB needs a new exhaust, and the airbox is split, so I'm gonna buy some dodgy pod filters, so a few months down the line I'll have a non stock exhaust and air filters. Which'll need sorting at a dyno place.

What exactly does that involve, changing the jets, or just fiddling with the mixture screws, and how much will I expect to pay for a carbed twin. Also, will the bloke do the sorting, or just tell me what to do to get it running nicely.

Also, what are dynojet kits, is it just a box with a bunch of jets in it, seems a bit pricey if so, and surely having to take your carbs apart a load of times to try different combinations is a pain in the arse.

Ta.

considering i want to fight/track my GS at some point and the fact i really don't care about fuel economy i've been thinking a similar thing. of course i want to get the bike working 100% first.

I was thinking K&N lunchbox, i've already got an R6/R1 exhaust on quite neatly and then tinkering with the carbs.

But i'd like to learn more about these dynojets.

Obviously we both ride twin carbed commuters with a hope of making them more than a pile of turd
