Ain't she a doll? :cheer::thumbup::Sport:

Perhaps, if the shop allows it, try to buy the parts on your own. Like I did, buying used parts from junk yards and ebay really saves a couple bucks. For the most part the shop would most likely use original Yamaha parts that really start to add up. Be sure to update, and good luck on the fix!

Hey all, final update! The bike has been running great! No problems what so ever (knocks on wood). Took it for about a 80~ mile ride down south the other day and ran great the whole time! Just had to refill the anti-freeze, because we had to wait for the bike to suck up what was left in the...

It's gonna be one sweet bike when it's finished. Sweet pics!

Oops I forgot to add the total price of everything once it was said and done. Overall I'd put the price tag around 300$. Not bad when your being quoted around 2000$.

Haha, thanks. Trust me, I couldn't of done it without the help of my uncle. The sharpied numbers were just to make sure the pistons were put back into the right cylinder. Each piston can have a slight difference in size and after putting them back into the right cylinder reduces the chance for...

Yeah, I actually explained it in a reply to FinalImpact, but for some reason it has to be checked by a mod first. I actually used my own pistons instead, and just used the connecting rods from the one off ebay.

Thanks! I hate to say it, but I'm gonna miss working on it! Maybe I just have to start riding again...

Thanks! - How did you check the bearing clearances? Plastigage is used to check the clearances on the crankshaft. You put a little piece of this stuff on the crank and tighten it down with either the connecting rods or main bearings. Once you take it apart there will be a slight square...

:cheer: Another update :rockon: The bike is nearly complete! When putting the bike back together everything went smoothly. Minor things like losing the pin for the cam chain rubbing block and making sure the intake cam was positioned correctly. Getting the motor back in proved to be an...

Hey all, another update on my progress. :popcorn: After thinking it over I got a used crankshaft with pistons and connecting rods from eBay. Turned out to be a great, cheap purchase. I also got 10x bearings, new timing chain and a new gasket (for connecting top and lower end of engine). The...

Yeah good point. I have a big feeling it's either one of those scenarios.

Hey all, sorry for the late reply. It's really hard to find time to work on the bike during weekdays with school and work! Lots of good info on this thread and really interesting to hear all these different view points. Overall, I've decided to buy a good 04' crank off ebay with rods...

Wow, lot's of replies. Thanks for the input everyone! Found that the main crankshaft bearings were in excellent condition. The #4 rod bearing had completely spun. The #2 rod bearing was beginning to spin. Rod bearings on 1 & 3 had some wear. Any ideas on why the connecting bearings were toast...

Re: Knock knock \\ Look inside before you go further! The (slight) knock started about 100 miles, after I purchasing the bike. Perhaps I even bought it with the knock and just didn't ride it hard enough to hear anything. The slight knock was between about 4.5-5.5rpm, only during...

Updates with some pictures. Decided to just remove the engine from the frame, and stopped the dissembling right when I got to the throttle bodies.

Thanks for all the ideas! Instead of putting the bike upside down I'm going to attempt removing the crank by putting the bike on it's side. If I'm able to find a bad connecting rod bearing I'll go ahead and proceed to take the motor out of the frame. I'm just trying to do the most amount of...

Right, I got the oil pan off, but was curious if it's possible to remove a crank with the engine still in the frame?

Hey, thanks for the replies all I think I might have found the problem, After looking similar problems on youtube I believe I've narrowed it down. The knocking is most likely caused because of spun rod bearing. I'll probably end up doing an engine rebuilt, but worst case scenario, replace it...

Just started working on the bike again. This is what I did : 1) Took the clutch apart and spun the input shaft. No noise. 2) Put the bike in gear and spun the rear wheel. No noise out of the transmission. Went through all 6 gears. 3) Took the oil cooler off, no debris at all. Was...
