con rod or crank pin?
I took off the backplate of my vspec to check the rod, and noticed that there was excessive play in the rod/pin. My question is, is the play comming from the bronze bushing in the rod or is it the crank pin?
Basically do i need to replace the rod or the crank?

The rod is softer and wears faster but if its really worn it can take out the crank pin.
If its the crank pin, then you have to replace the crank, but you STILL have to replace the conrod anyway.
So I'd start with a fresh rod and test it on your old crank.

thanx. How hard is it to change the rod out?

Its easy. Hardest part is getting the head screws out without stripping them. Push real hard before turning.
Then just be careful pulling the wrist pin spring clips out. You can't just yank them out or they'll take part of the piston with them. You have to compress or wind them up a little. I haven't got a good technique for that yet. I'll let someone else chime in on that.....
And note the orientation of all the parts. You don't want to be the guy racing a vspec with a piston in backwards (worked, but ghost flamed out. Actually seen people do this more than once )

also will a hole in the carb boot act like a air leak?

bump for more info please

A hole in the carb boot is a big problem. Replace it.
I use an oring, or if that deosn't work a small zip tie at the base of the carb boot to keep it sealed. the oring is gentler and won't lift the boot like an over tightened zip tie. Doesn't work on all engines.

How much play are we talking about here? how many gallons you have on it? I ran my v-spec with a pretty good amount of play in it and it seemed fine. But I don't know what your situation is =X

5 gallons. and it has a good amount of play. well you can see it wobbling in there at in and around tdc. I will be getting a new ninja this week. also if you have to replace the rod and crank, bearings etc. wouldn't you be better off getting a new one? a crank and rod is about 150$$ so that would be half the price. With tko's it would be closser to 200$ so i guess if you rebuild it with a speed crank you would have a better engine anyway. i guess when the P/S go you can get a pinch or replace it.
