    R&D performance heads installed - rejetting

    Just finished installing R&D performance head kit for my 2002 xlt 1200 and was wondering if re-jetting is necessary and if so, what would Re-jet specs be? R&D claims that no re-jetting is necessary, but with additional compression, I figured more lean conditions would happen?

    BTW.... Reading now 150psi across all 3 cylinders. I did start it up and run for a few minutes and all appeared good. Appeared I did get more smoke than usual ..... Should be noted that I have free flow exhaust kit installed.

    Any advice is appreciated. Thanks!

    Your ok with the heads installed. Are your carbs rejetted already? Are there any other mods done? You should have a tach installed when tuning or doing any engine mods.Just a cheap Tiny Tach will do.

    Bumping this up for some info, there are a set of R&D heads for sale and i am possibly thinking of picking them up. My question is can I just slap them on the my stock 1200R ? I actially have some rebuilt carbs with Riva FA and choke delete. Do I have to change jet settings or what ? My first time trying to mod my ski so I am a bit noobi at this
