1991 Exciter 2 wont idle

Hi all, I am new here but have a question

I just bought at 91 exciter 2 as a project sled and put a new piston in it on one side from a parts motor. I have 130 psi compression in each cylinder and just cleaned the carbs on it. Gas should be pretty fresh.

Now for the question. I start it up and it will run great and idle for about 3 to 5 seconds then it revs all the way up and has no throttle response, What could be causing this? It repeatedly does this each time we start it? Is something sticking? Also how do I know if the oil injection is working?'

Any help or suggestions would be great?

Thanks

There must be an air leak, carb flanges or crank seals.
Which piston did you replace, the PTO [clutch side]?

First is the Belt on? NEVER run a sled without a belt!

I replaced the non clutch side piston and cylinder. How do I find an air leak? Also the dive belt is not on because the clutch engages right away and I don't want it to take off without my back end propped up.

theres a chance you have one or both of the slides hanging up. i would remove the carbs with the cables attached and confirm the position and operation of the slides.

to rule out an air leak, you can spray carb spray or ether around the area of the seals or even where the carbs attach to the cylinders. if the rpms increase, you have a leak. depending on how high your revving it may not be noticable.

check your carbs first.

okay found one of my carbs was hung up so it was wide open and also found a leak at the bottom of one of my cylinders. Both of those things are fixed but on to the next problem.

It will start and ilde great now, but it doesn't have any power to it... It will rev up to where the clutch wants to engage but then bogs down? I did get it moving but it would only go 15 mph and sounded rough. What else should I be checking. I am currently cleaning the carbs again and replacing the gas.

that almost sounds like your tors is activating.

Alright guys I have been reading about bypassing the TORS but cant follow what two things to plug together to do it. In the first picture those are the two plugs that come from the cdi (and by what I have read they should plug together) However they are the same plug and do not go together. The second picture is the plug from the carb on the left and the other is from the cdi (these were and have been plugged together)

So How do I get around this problem? I think this is what is causing it not to run above 3000rpm because it runs great below that.

Thanks

On the carbs there are two wires that plug into the main harness.
Unplug them and connect the harness ends together.

those pics look more like the connector for the bar and key switch, just guessing.

you need to look at the carbs for the bullet style connectors and deal with those and it should all come to light once you find them.
