What size jets did you use and brand? I’m working on a 02 Raptor 660 has same air filter as yours and full exhaust what jet sizes should I order?

My 05 raptor 660r also bogged spits when I open full throttle any suggestions how’s to fix. It feel like it’s not letting me use full power also missing air filter the air box it’s there but no filter

You will have to order the OEM air filler guide, plate element fitting and a UNI air filter.

Valve lashed

Your reverse wire could not be grounded properly. Happend to my 03 all I did was ground it and it stopped the issue

Hopefully you’ve figured it out, but you need to have the air filter or it won’t run properly on stock jetting. Get a stock air filter, UNI or K&N might require carb adjustment. Make sure the carb boots are in good condition, if they are cracked; replace them. Research on raptor forum. Theres how to’s for everything

I never wear gloves just use orange hand cleaner

[@dnaday-send3548]

All do respect pls get rid of that K&N. It’s not doing any good brother.

[@dom_offroad]

Oh I agree I hate K&n lol might as well run no filter! This was in it when I bought it and was just fixing it up to sell.
