i got a bent valve on the F2. is it really that hard to fix it my self or what? i have never really done any internal motor work on bikes though but i have on a car

 

how do you know its a bent valve?

 

had a air box screw go through the carbs and sit on top of the valve while running. took the tank off and the air box off and started it and now it shoots gas back out of only one carb. the carb that the screw went through.

 

i suggest a new motor. did the screw make it into the cylinder?

 

no, it only was on the top of the valve. it didnt make it into the motor. i just want to get the valve replaced that is bent.

 

It most likely damaged the valve seat and the head too....

I'd buy a used engine.. not very expensive for those bikes... or just upgrade bikes and fix that one later for a spare..

 

or sell it to me! ill give ya $100

 

i really dont want another bike right now. i really like my F2 with all the stuff i have done to it. i am just going to replace the head on it. and just go from there.

 

its so old that your bound to run into more problems with the tear down of it... might end up costing as much as a motor.. it def will in time u spend doing it.

 

i was told i could uprgrade my motor to an f3 motor. supposed to bolt right in. but i need to get a motor kit too. just got beat on ebay for a f2 motor for like 220 bucks. shipped. with 9000 miles on it. oh well. any one here got a motor

 

Ouch that sucks. I floated a valve once in a 00 zx6R put a new valve & guide in and also had the seat re-cut. It marred the piston but it didnt hurt, took a die grinder to it.....Its went till 33,000 miles until rod failure....knock knock...............whos there.................rod.................rod who................rod thru your case.

 

ha ha that was a good one man. yeah my buddy works at a bike shop and he is going to come over and help me fix it. but while my bike is in its downtime is the perfect time to put my new shocks and dirtbars and hand brake and **** all on

 

Yeah thats the only thing good about the bike being down...you take your time in setting up everything perfect. You dont get in a hurry and miss things, its not like you can ride after you install it all...U get my drift right.
