VicVenture Posted June 18, 2009 Share #1 Posted June 18, 2009 I have a 1992 Venture Royale that has 85k miles. It has a "knock" when idling that appears to be a rod on the left rear cylinder. My question is whether this is a project worth undertaking or should I part out the bike? Has anyone torn down a motor. What is the estimated cost if I do the work myself? Thanks for your comments.

foxman Posted June 18, 2009 Share #2 Posted June 18, 2009 Does the sound change when you pull in the clutch? If it does then pull your side cover off to expose the clutch basket. Then grab hold and see if it moves up and down. You might have a bad, or at least worn shaft bearing. It's behind the basket and the case has to be split to change. Mine has done it for 20k miles.

a1bummer Posted June 18, 2009 Share #3 Posted June 18, 2009 FYI. Last year I thought I had damaged my bottom end. Of my engine that is! I swapped out the engine and after about a half tank, I started hearing that noise again. I turned out to be the exhaust collector. Opened it up and tore out the loose baffle and the rest of the innards, welded it back together. No more noise. If ya gotta take the engine out, you gotta take the collector off anyway. I would inspect that just to make sure it isn't what's making the noise. Link to comment Share on other sites More sharing options...
Yammer Dan Posted June 18, 2009 Share #4 Posted June 18, 2009 I would check for other things. These engines are pretty much bullet proof. I have a 84 engine with 98k that runs great. Link to comment Share on other sites More sharing options...
jasonm. Posted June 18, 2009 Share #5 Posted June 18, 2009 I have heard knocking noises on one Venture that the choke linkage(left-right) had popped off and only running on choke on th eleft bank when cold. What a racket. Noise disappeared once warmed up. Easy fix on that one with a "c-clip". Also a clogged carb can give rattles due to running on a dead cylinder.

VicVenture Posted June 19, 2009 Author Share #6 Posted June 19, 2009 Thanks for the tips. I will be trying all three at the first opportunity. I already know that the baffles are loose, but the noise just didn't sound right for that. However, you are right, no harm in trying that first. This is a retired Police bike, so the clutch could be worn from excessive use. Maybe I will get lucky, and not have to split the case. I will post the results. This forum is great for gathering knowledge from several sources. Thanks again, and any other ideas would be appreciated. Link to comment Share on other sites More sharing options...
skydoc_17 Posted June 19, 2009 Share #7 Posted June 19, 2009 Hey Vic, I have a 60,000 mile 1300 VR motor with no problems you can have for $100.00 It's not the prettiest motor I have ever seen paint wise, but it is a good solid motor. You'll spend more than $100.00 :mo money:for gaskets if you split the cases on your motor. Earl Link to comment Share on other sites More sharing options...
Yammer Dan Posted June 19, 2009 Share #8 Posted June 19, 2009 85 k on a cop bike? I'd bet on clutch. I don't think you have to worry about it blowing. Link to comment Share on other sites More sharing options...
Texaskid Posted June 19, 2009 Share #9 Posted June 19, 2009 I Had the same knock too. Thought the clutch was going. Pulled the clutch in and the no9ise would go away, then when I got the carbtune and syncked the carbs, no more noise. They were out really bad.
