This is on my 73 TX750.
I've been chasing down a popping out the exhaust. It does it some times just at idle. But more so when I let off the gas. It is in the low end rpm range.
So far I've done the following, with out fixing the popping.
1. Re-built my 72 XS2 carbs with new butterfly seals and put on there.
2. New NOS carb boots after I found an air leak.
3. Adjusted cam chain.
4. Adjusted valves.
5. Set points.
6. Checked timing. Both sides are with in 2* of each other. But then I broke my light before I could finish. Hope to get a new bulb, or borrow another light to make it perfect.
7. I re-jetted the pilots. I tried everything from 42.5, all the way up to 50.
8. Finally re-built the original 73 carbs with new butterfly seals after I still had an air leak on the 72 carbs due to a bad carb body @ the butterfly seal.
I had read about an exhaust leak can cause a popping. Well I hope the hell it can, cause I'm about to loose my mind.
This TX750 has a strange exhaust system. It has a cross over manifold on the front of the motor. And today I found a leak.
Here's the manifold.
Here's the leak I found. Do you guy's think this could be causing my popping. I have new gaskets on the way. I'm sure open to suggestions. What am I missing.
My brother seems to think it could be the cut off exhaust that the PO did. He thinks since there's not a tip on the pipe, it could cause it. What do you guys think about that.
