Hey friends, I wrote to all of you some time ago about having my timing belts changed. It's an 83 Interstate 1100 and it ran perfect and quiet before . I almost dreaded having them replaced but am traveling back to NY next year and didn't want to chance them breaking as it has about 55,000 miles on the bike. Anyway, my ex-mechanic changed them and it ran terrible, noisey, no power etc. He took it back and said it was lest than one tooth off , which concerns me. How can it be "less" than one tooth off? It's either one or more teeth off or it's not. Anyway he took it back and had it for about a month before I had to recover it. Now it doesn't start. Sounds like it cranks too easy, like no compression. I asked him why it didn't start and his answer was that the generator weights were 180 degrees off and that this is common on these bikes. And that I need to remove the rear tire and swing arm to get to the generator bolt to be able to turn it 180 degrees and then the weights should fall into place and it'll run fine. Does any of this sound right? As far as I know all he did was change the belts and never removed the tappet covers or adjust any valves. Ant help would be appreciated. Joe

joe this dosnt sound good .....just need to get the bike home and start over it sounds to me that its got a bent valve already ...icant remember which side it is that everybody gets wrong...joe its the rare machanic that can work on these wings without stumbling....
take the valve covers off
take the timing covers off pain in the butt
take the plugs out
take the timing mark cover off
have it on the centerstand and either with the stator bolt or in fifth gear turn the motor till the timing mark lines up
check to see if the belts line up with there marks
if they do turn the motor over easy by hand to see everything operate and nothing is hitting and the valves are not binding
i think one is or more
but if you think everything is working right then spin the the motor with the starter with the plugs out still and check the compression
this will tell you where the trouble is with loss of compression from bent valve or what ever.....
after they have been set wrong and ran to the point of valve damage it dosnt matter if you set it right after that its still broke
go slow and careful its very easy to trash an engine at this point and dont spin it with the starter no more till you think it ok to after checking everything ...you might see the problem from just taking off the valve covers
thats a pretty wild story the machanic is trying to say what happen ...right at the same time the belts were being changed :mrgreen:

I agree with Joe! Your ex-mechanic is taking your for a ride (no pun intended)!
It sounds like the valves may have gotten bent. :rant:

:shock: :shock: WHAAAAAT???Sounds like a shuckster response if I ever heard one!
Sad to say, I agree with the others...he bent the valves by not having it timed correctly, and he's just wanting to blow smoke up yer butt about it. "Less than one tooth off"??? He must be from Kentucky.... :smilie_happy: :smilie_happy: :smilie_happy:
(Just kiddin! :mrgreen: )
I'd bet you have bent valves, too... :rant:
:hi: Sorry to say it sure sounds like the valves have been damaged. I didn't need a mechanic to damage mine. I did it all by myself. :head bang: Setting the timing belt on the right side,(throttle side), can be a little tricky. On mine the intake valves on the right side were damaged. I think it's the #1 cyclinder had no compression at all. Fixing it was not difficult with advice from other site members. :help: It just took some time to get it done. My bike is running better than ever now. :clapping: if I can be of any assistance let me know.

OY VAY!
That guy is NOT a mechanic. Keep your bike as far from him as possible!
1. There is no such thing as this so called problem with generator weights.
2. You are correct, a belt cannot be less than 1 tooth off.
3. Cranks too easy sounds like no compression. He bent valves. This can be confirmed with a compression check.
Sorry to hear HE screwed up your bike.
Let us know what your plans are now.
If you want to fix it yourself we're here to help.
Yep,like dan and you said,its either off a tooth or its not.And it dont take much to bend a valve.I had mine off a tooth,right side also,and bent them but hand.
As far as his laim excuse,well hes got a hell of an imagination.
The only thing I can think of that might slightly redeem this moron is if by "cranks to easy" means the starter pucks are not ingaging.But you wouldnt have to remove the tire or anything else for that matter.Mine does that (starter clutch not engaging)usually in the spring,after sitting all winter.I drain the oil,soak the jug of new in hot water for a bit before filling and it starts right up.Then good all summer providing the batt stays good.
Only grabbing at straws for ya,but Id do a compresion test,double check the belts and file a complaint assuming he is a legit business.If hes just some gravel back you are screwed.
