did you let the paint cure out or just paint it and fire it? how's your jetting? have you done a leakdown test yet? is your choke tube still intact?what fuel are you running? is your engine detonating? running hot is usualy a sign of lean jetting or an air leak but if your timing is advanced it could be from not running fuel without enough octain...

the paint cured for like 2 weeks , jetting is goood , no leakdown test yet, choke tube is in place , 89 octane

Unless you have an egt gauge, noticed discoloring of the head or cylinders, or have a water temp gauge there isn't really anyway for us to determine if its actually oveheating based on what you told us. A decent running engine will make egt temps of up to 1250 degrees, so 650 degree paint aint gonna cut it. You need to use high heat exhaust paint or have the pipes ceramic coated.

i'd say that with a 4 degree timing advance you should be running at least 92 octain fuel. i think even yamaha says to run 92 stock. the 89 might be a major reason your overheating... as Snopczynski said 650 degree paint realy wont cut it on a head pipe. i have some nasty ceramic 850+ paint on my stingers and it's bubbled from the heat...i'd also be looking into that high idle, has it always idled high or did it just start recently? i'd for sure do a leak down...

you can hear the water bowling in the rad.

 

Its probably not boiling, cause if it was, then it should be running out everyhwere. Its normal for the coolant to get pushed out into the overflow and then sucked back in as it cools down. You will hear this happening.

 

If you have your mind made up that its overheating then replace your radiator since you know its bent. Always do the obvious repairs first. Just to let you know, my old banshee had a bent radiator and it never overheated.

well i took her out today for a ride. ridin for about 15 mins and she starts to get hot. boggin down in every gears and then it will start to backfire on me. wat is goin on?

I don't think you ever gonna be able to paint your exhaust and be sure that it will stay on. Exhaust pipes get way to hot to be putting spray paint on them well in my opinion. You may have air pockets in your coolant as well. There are two bolts on the side of your jugs that you unscrew and then put your coolant in when the coolant runs out the bolts on the side of the jugs then tighten them up so you don't have any air pockets. Alot of people on here will tell you that the bolts are there because of just draining purposes but i've learned first hand that there is a possibility air pockets could form and there fore won't cool properly. But hey different strokes for different folks i do it because i believe in that and for safety precautions.

Backfiring is a sign, that it's lean. Maybe an air leak, or just too small of jets, or maybe even your fuel flow is restricted some where. You need to find out what the problem is, before going riding again, or you may end up rebuilding the top end.

get some new plugs and do a chop. and get a radiator that isnt bent preventing coolant flow. use 91-93 octain, and try some engine ice. Stock impellers have been know to fail too.
