it has a twin carb steup from paul turner im not sure how to tell what size they are

hey sorry its been so long i have been hella busy i tried to load my pics but it says the file is to large ! and ill sell what ever i cant use and what i mean buy streetable is i want to lower it and put street tires on it and use it mostly and a 1/4 mile track but also be able to go to a street track and be able to at least compete ! angin all the help is very welcome !

well im in las vegas and the elevation hear is right about 2001 ft how but from what the person i bought the quad from said it came from cali just not sure where in cali !

first i want to say thanks for all the help with my last post!! i just bought a 97 banshee with a bad #2 cylinder the bottom end is fine and it has a hot rods stock crank and connecting rods. it also has a PTR cool head with 17cc domes, a set of PTR hi rev pipes, and a keihin twin carbs set up. what i need to no is can i ues any of the parts that made it threw the burnt #2 piston, or should i start from the begging? i dont want to go with the tt style motor but i do plan on lowering it and putting some street tires on it. any help on where i should start looking and what kind of motor i should look to build would be a great help !!!! thank you

ok so i just got home from tearing down the entire motor and getting all the part numbers off the crank, connecting rods, pistons, cylinders, and heads. it has a hot rods stock crank and connecting rods. paul turner heads with 17 domes (not sure what that means yet could use some help there) paul turner high rev pipes im not sure what type of cylinders it has but they have been ported and the part number is 347cm3 i think and i could use some help with what type of pistons it has i found what i think is a part number on top of the pistons its 58436 and it also has a twin set of kehin carbs part number 295bonjm if u can help me figure out just what was done to the motor it would be a big help. im going to rebuild the motor because when i pulled the number 2 cylinder off the piston was f#%ked !!

Ok this is great !! I dont like any one working on anything I own so that was a great link for a pressure tester. I plan on getting back to work on the banshee in about an hour and will take some pics and post them. I know alot about high reving motors (thanks to the honda b series) and I know will catch on quick with a little help thanks again. Ill have pics posted later today.

What is the best way to do a pressure test on the top end ? Or would it be better to just take the top end to a shop and let them run that test?

Wow thanks !! I honestly didnt think I would get such detaled info ! I do know that the right cylinder head i pitted BAD!!!!! It almost looks like a piston ring went bad and spent some time in the chamber getting smashed against the top of the cylinder. I did do a " getto" compression test buy putting my thum over the spark plug hole and kicked it about 5 times and I could feel a little pressure. I will run a real test and get the results posted as well as some detaled pics. Again thank you for replying to my post! I have always wanted to build a banshee and it does look like it has some money into it I just want to make sure I know what was do so when I get deep into it I know where my starting point is .

Hi my name is mike i just bough a 1997 yamaha banshee. I can see that it has PTR pipes (im not sure if they are hi rev or mid range) and a PTR cool head , with a twin carb set up. It has a bad right cylinder and Im trying to figure out what all has been done to the motor. The previous owner has no idea what was done to it, becuase it scared her and then her friend blew it up (Im going off what she said). I plan on building it for trail ridding but I want to know what all was done to the motor, is there any way I can tell what was done to it? I will be doing the work my self and I have the skills needed to do so (I have about 15 years building cars under my belt) but dont really know what to look for. Any help would be great !!!
