I'm assuming the diagnosis is bad lower rod bearing. If so, how does a mechanic know this for sure? Are you confident in your mechanics diagnosis?
You mentioned an upgrade to 1200, did someone do this work and then just not put it together? Could it be a sloppy top end job and the ticking is the piston skirt?
In either case something needs to be done before failure.
Before I bought any parts I would do a compression & leakdown test to get an idea where the top end is. And maybe before taking motor out of bike disassemble top end and measure jugs & pistons. At that point you can spin, push n pull on the rods to try to get a feel on the lower rod bearing.
Well....I would take all apart and figure what's needed and cost. You can see if its worth it at that point.
Best advice so far. You really do need to know what needs repairing/replacing before you roll up your sleeves and dig in.:coffee This could be one of those projects that you start and wish you had not, so do the homework first.:s
Thank you gentlemen,
Ok, I'll try to answer.
Diagnosis is worn-out/ bad crank shaft.
I took the bike to the mechanic with the loud ticking noise (like a loud sewing machine type)
I bought the bike as a basket case where 60% of the bike were brand new parts.
The engine was all together with a 1200 upgrade done.
A 3" stack of receipts for all parts and engine work totaling $7K
The guy had gone gaga chroming or buying new chrome everything (nuts, bolts, front end etc etc he really had lots of money into it.
I put the bike together and just mounted the engine the way it was.
Since the first time that I started the sound was there.
I checked everything I could think of and everything I was told by the good ppl here in the forum.... But sound never disappeared.
That's how I got to the mechanic.
When I took it in he listened to it and rode it around the block a couple of time..
He said that it sounded like the 12 upgrade was done in old cases,cylinders etc and it sounded like an incredibly loud valve train.
We agreed that he would double check things...check valve adjustment and push rods adjustments to see if it would get any better.
He called two days later and told me that he had taken the front cylinder off and that after inspection his diagnosis was * a Bad crank shaft.
The shop has an incredible reputation for being honest and straight ppl... And I didn't feel like he was lying or anything like that.
I picked up the bike and reviewing what he told me what I can see is that if I move the piston rod up and down it seems pretty tight just the way it should be but when moved to the sides it has about 1/2" of movement and he explained that that was the big problem.
How does that sound so far?
Sorry about the long post
