Done.

I am having the moderate Yamaha tune done to my bike as we speak here in Canada. The RZ500 factory tune that you guys have on your page. Most people say that we should use TM Mikuni 28m flat slides. I have found flat slides for a great price but was asked if I wanted TM flat slides or TMV flat slides. He mentioned that the TM 28m flat slides were used for four stroke applications not two stroke applications. What should I use for my application.
My application will be the factory tune with jolly motto's or the JL's they look and sound nice to. Help
Thanks Colin

If the TMs are jetted right, they should work fine.
Or if he can get keihins, PWK28's are also great.

Thank You I got the TM 28m With the JL's on the way, can you guys sugest a starting point referance the jeting with these carbs and the JL's with the factory tune in the above section.
Thanks again.

Don't think those links are working anymore...

You're right.. I'll have to find those files again. I didn't even realise they were in a strange directory when I did the last migration.

Links fixed and RDLC added too.

Links are broken again.

Typos on my part... should be working now.
