rejetting - easy job??

how easy is it to change the main and idle jets in my carbs?
do i have to remove the carbs from the bike?
can i get to them by removing the tank?
do i have to do a full carb strip down?

thanks
Ian

Edit: I was confused. You will have to pull the carbs to change the idle jets. Pulling them being the hardest part of the job. Be very careful while unscrewing brass, it will break easily.

also are these the right sort of jets?

haynes manual says main jet size is #90 so if i go to pod filters should i go up to a #95 or isn't it that straight forward??

You could try the 95's, but if the only difference is the pods, then I'd try a 92 or 93 first. The rebuild kits out there come with the 92's usually.

If you have a 4-into-1 exhaust, then 95's should work. I found that sometimes you need to go up a size or two on the idle jets too otherwise the bike needs to stay on choke much longer and it stumbles until the bike is thoroughly warmed up. I drill my own. Larger idle jets are hard to find. Don't enlarge the idle jets until you are sure you need to, though. Sometimes it's not necessary. It seems to depend on the exhaust's characteristic at lower RPMs. Kerkers don't need it, but Macs need bigger idle jets.

.

The only mods are the 4-1 motad exhaust and the pods.

It stumbles at idle as it is, although i figured that was because of the cold air over here!!

I'll try the 95's and see what happens, wont be until after christmas now though, no dollars!!

iandz500, The jets pictured are not Tekei main jets. Hard to tell from the pic, but they sure look like Keihin main jets. If you want to use Keihin main jets, you certainly can... they are shaped differently but the threaded part is the same and the numbering seems to be the same, size wise. You can get the correct Keihin main jets from z1enterprises.com - I am in the carb business and I don't think new Tekei main jets (or pilot jets for that matter) are available except perhaps in carb kits.
