Won't start after valve adjustment *UPDATED*

I went down to my valves and replaced the shims, have good clearance, good battery, looks like I put it all back together well. Any ideas on what I might have missed?

----------------------
UPDATE

I can now get it to start it will only fire on the right two, but once I get the rpms around say 4500 both fire. I think I need to sync my carbs. -$$-

you pinched the fuel lines when putting tank back on, or you forgot to turn the tank mounted petcock back on.  dont ask me how I know.  ....................ok, Mr. Adrian Monk told me.

Ok I tried that and now when I try to start it, it now sputters then turns over and starts to make a puffing sound (like as if on one cylinder).

:technical:

Good call btw on the gas tank shut off.

you adjusted wrong maybe. double check.  make sure you didnt confuse the intake with the exhaust.

Is it running on one cylinder?  It is possible you could have knocked some crap loose in your fuel lines which clogged a carb.  Ask ver4 about that   :laugh:  Did you open the float bowl drains on both carbs to make sure they are getting fuel?

dont the exhaust clearences differ from the intake? maybe he switched em so the valves are opening at the wrong times and causeing low compression

BaltimoreGS

The clearance spec. is the same for the intake and exhaust valves.

Whew had me scared. I have good clearance. I still figure carbs.

Did you put the petcock on Prime for a few seconds, then back to ON?  Did you choke it?

are your plugs good? have you checked for spark? how old are the pugs, and how much have you tried to start the bike without it firing. sometimes plugs can get compressed with fuel which grounds them out, but they will still fire outside the cylinder just not inside under compression.  Also you didnt mess with the timing at all did you? shouldnt have had to mess that up when setting valve clearence

SonsaFrantic

Lol yeah I have the plugs caps on. I didn't mess with the timing. Not 100% sure about the plugs. I'll buy some new ones if all else fails. It's looking like more and more like the carbs =/

This is why I'm afraid to tackle a job like valve inspection/adjustment that the more (much more) mechanical gifted guys here consider "not difficult". I found out even a simple oil and filter change can turn into a multi-day headache the first time I did it. So for valve adjustment I let the shop do it at $100/hour + parts to save me my sanity.  :laugh:

SonsaFrantic

I can now get it to start but only halfheartedly, and anything before 4500 rpms the right side is the only side firing... HELP!

Haha, funny guy.  :flipoff:  ;)

Sonsa, what Jessie was referring to was this past Saturday when I wanted to take my bike out for a ride the carbs were clogged.  It just made my day worse.  Also, I have no mechanical skills whatsoever.

Check for a loose carb boot (carb to engine and carb to airbox) as well as loose vacuum lines. These can get bumped loose during this job.

Based on symptoms dirt in the pilot is most  likely. But it seems odd that the carb would gum up during the valve job. I take it that the bike was fine before you pulled the cover?
