I guess you mean not screwing up the main mounts to start with, because I don't know how doing a crappy job in the first place pertains to this.I did much the same..and while I hated this bike so I never cared to do it right it was my proving grounds. I cracked the engine block casing where the J Shaft plates go on this bike.I let something else loose get though...[rattling did it ] The rattling motor stole horse power too. Why I never cracked the frame where I did the cheesy front mount is beyond me but I will never do it that way again I guess I live and learn
Cracked the block? Loose parts rattling because of poor rear mounting? Not tightening the two nuts at each end of the keeper shaft together so they don't move? What, you were expecting a front mount to compensate for all that?
This thing didn't vibrate at all. Zero, none, and it didn't even have padded grips so you feel everything.
The only vibration I felt was the cheesy front tire starting to show it's 'out of roundness' at 40MPH.
In fact the the 50 something year old doctor I did the JS upgrade for called, he wanted to verify my address to send me a Christmas card with a tip.
He took it out and ran 1/2 a gallon of gas through it, said it does 45 in 7th gear, and LOVES it!
Then he asked about the 6 U clamp nuts I told him to check often and he wanted to know how tight to make them as they felt very tight after his rides. In short, still perfect. No vibration, no loosening, no frigg'n rattling or broken blocks or mounts.
Scoff all the heck you want, I love this mount and about to put a bigger motor in my JS'ed bike and going to use the same design for it's front mount, just slightly modified design and material.
Corgi1, the motor pull via the JS is straight down to the BB, the frames BB and drive sprockets have the right right side pull on it to the wheel, not the motor. The only pull the motor itself from the JS out is to the right by the JS out and BB connection which is next to nothing.
And Vince, thanks for the 'good luck' wish even as snide as it was meant.
You and I got off on the wrong foot but we both think the same way, not lame one build fixes for problems but universal ones and the same philosophy about how lame a drive side tensioner is.
'Nuff said.
