To whomever will listen...
I have had a 1974 CB450 for 8 years and I have never gotten it to run right.
When I first bought it I blew the original engine. I had a shop install a 500T.
Then it would never run right. I could barely hit 65 to get on the highway...
I've tried everything at this point...
It had a ******* exhaust where the original pipes were extended or some crazyiness (def not original), so I had a custom exhaust made. This was also to get rid of the possibility of exhaust leaks because I heard how much that matters.
I replaced the exhaust gaskets.
I have rebuilt the carburetors.
I have tried both the stock air filters and the pods from common motor.
I have gone through the regular maintenance procedures.
I have synced the carbs.
I have gone up and down the main jet scale.
I have tried checking the spark plugs for rich vs lean. Not really successfully I think...
I have put on a new petcock.
I have changed my fuel lines.
BUT IT STILL DOES NOT RUN RIGHT!
I dont know what else to do at this point...and now the starter isn't working...
It idles fine, but when I try to ride it it backfires and won't exceed like 5000 RPMS.
I am at my wits end and am 5 seconds away from selling to the best offer even though I dont want to. It was my first bike and I cant afford another one and there is no way my wife would let me buy another one.
I have some photos if anyone cares...only able to upload one apparently...
