The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

2001 Honda Sahdow 750 Torn Diaphragm

Hello,

Sorry to direct a question about another bike on these forums, but I know many people here are very insightful and I was hoping for a bit of clarification/

The bike is a 2007 Honda Shadow VT750DC with 27k miles

When I bought the bike it was running good but not perfect, and It had sat a couple years so I assumed just a simple carb cleaning. found out the Diaphragm was torn for the carb going to the front of the V style motor. Ordered the parts and I am waiting. The carb was pretty clean overall.

Put the bike back together and it seems to be relatively worse (Lean), I believed due to just making the diaphragm tear slightly worse during inspection. Although I also briefly checked for vacuum leaks around boots.

My question, can a tear in the diaphragm going to the front cylinders cause the rear cylinders to run lean? The diaphragm for the rear cylinders is being replaced as well although it seemed in okay shape. I ask this, because within a minute of running the rear exhaust gets excessively hot while the front exhaust is only warming up at a typical rate.

It led me to believe upon putting the bike back together, I did something incorrectly to cause the rear cylinders to run so lean, It was a bit of a pain in the ass trying to reassemble my first 750.

Also note, the a/f screws have not been touched to my knowledge as the plugs are still in place, and I did not plan on touching them until after installing the new diaphragms.

If the answer to my question is no, then I am a bit clueless as the why the rear cylinders are running lean suddenly. The sparkplugs require a slightly special thin walled deep socket to remove them and I have been unable to check them as a result.
