So i just picked up this 1997 ZRT800 a couple of days ago, the thing runs great and is in awesome shape. The previous owner stated that it had a 1050 or maybe 1150 big bore kit in it. Now i know the only way to actually prove this is to open up the motor and take some measurements but are there any things that I can look at to tell if it is before opening the motor? I noticed that each cylinder appears to have a spacer under the jugs, it does have vforce delta reed cages and i dont think the pipes are stock as the ones that i have looked at online look a bit different. so if somebody could id the pipes for me that would be great, they appear to be going into a stock can. On a side note i picked up a 98 z440 the next day for cheap, gotta love the end of the season buys. Also i do have experience with 2 strokes, all in the form of honda 250r's and some other toys, so im not afraid to open it up if i have to to prove the size of the engine just dont want to if i dont have to.
