short part run ride today-vibration issue or lack thereof

[TeamCheap]

I needed a headlight socket for our blazer(another sad story) so we jumped on the bikes and went off to the parts store.
After getting the part we took the long way back home and I thought to ask my wife to pay close attention to the mirrors on her bike.We just recently did a rebolt of the engine bolts.

As some of you know the bikes vibrate so much that the mirrors become useless but after a few minutes when we stopped at a stop sign she said they are fine, little vibration, mirrors totally useable, big difference after doing the engine bolt swap she said.( :lol: she said "I can see things in them")

It amazes me just how different the engine bolts can make on these but then again after looking at how they were done to begin with it's really no wonder the bikes vibrate with the stock engine bolts.



Ok I'm done .....sorry to bother ya
:lol:

I know you posted somewhere else... but... did you redo all the engine mounts? what size bolts?

I redid my top rear motor mount bolt with some 7/16" grade 8 ready rod, I didn't loosen the other bolts though, and the original was a bit smaller, so I had to hammer it in with a rubber mallet, but it seems to fit alot snugger...

Did you torque the motor mount bolts or just do them up tight?

:lol: yeah I did post the sizes as best I could remember here http://www.chinariders.net/modules.php?name=Forums&file=viewtopic&t=1810&postdays=0&postorder=asc&highlight=standard&start=15
The top 3-hole brackets are the most work but still very simple.
Heres what ya do:
Snug up all the other engine bolts except the top 3-hole bracket bolts.
Take a piece of paper and a pencil (must be pencil) and hold the paper over the 3 holes and carefully outline the hole edges (move pencil back and forth over holes)DO NOT MOVE PAPER UNTIL ALL HOLES ARE MARKED.
Once you have your template lay it out on a 1/8" thick or so piece of steel and carefully center punch the holes to help guide your drill bit.(take your time here it is the most important to get set right)
Next drill out the holes with a drill bit that fits the frame hole just right not loose or tight, I used a table top drill press but a hand drill would work fine also.
Next I cut and ground the edges until it fit right then layed it on the steel and made a copy.
On my bike with the different engine I didnt need the little spacers on the 1 bracket but the wifes bike still needed spacers so I just used a couple of washers at each of the frame side holes.

I redid all engine mount bolts on mine but had to redo the upper rear engine mount on the frame.
On the wifes bike we just did all engine mount bolts except that long one(upper rear) for now.

I didnt hammer any bolts thru the holes I just very carefully drilled out the holes to allow the bolts to slip in with a little effort.I made the holes just slightly, very slightly larger than needed for the bolt.

no torque wrench used (my bad) but I feel comfortable with giving them all a nice hand snuggy.

Sounds good, thanks for the info. Yeah I didn't torque the one I did either, I was just curious.
