I'm no mechanic but 'inclined' in ways I guess. Taking apart my motor because I'm either going to have a right side crankcase TIG weld done OR will split the case and replace the right half with a new one (damage to boss of drain plug/threads/real mess there). Either way, I need to get the engine out and get at the crankcase. Anyway, that's another story.
So far I've removed the silencer/pipe, taken off the seat, gas tank, plastics, and removed the carb. The cylinder/top end will be removed next so all that's left is the crankcase (after I remove the gear shift, kick starter, brake pedal). I have a Clymer guide (as well as the service manual) to guide me. So far, so good.
Just pondering a few things as I get farther into this / looking for feedback:
1. While I have it apart, and since I have NO idea how many hours are on the top end (PO didn't know either) I want to have the top end rebuilt. I figure I can just take the cylinder/cylinder head and piston into a shop (have a couple good bike mechanics in the area I was going to get estimates from), have them rebuild the TE, then I can just reinstall it myself once I have the crankcase repair completed. What's all 'included' in any decently done top end 'rebuild'? Is it one of those 'it depends' answers based on condition of the piston/rings/sleeve/cylinder head/cylinder/exhaust valve, etc? Let's assume those are all in good shape with just some carbon deposits to be cleaned out and the rings (of course, from what I've read) replaced with new ones, along with all necessary gaskets of course. The bike has ran GREAT since I bought it in October (not that I've ridden it much). So what can I expect a pro mechanic to check/replace/re-use assuming most everything is already in pretty good shape with the TE?
2. When I took the carb out, I also thought 'why not have it rebuilt, too'? Again, PO said he didn't do anything with it and he was 3rd owner, but it seems to perform fine with idle, throttle response through the gears, etc but hey---I have it out/apart. Why not do a rebuild of the carb too, so that, as with the top end rebuild at the same time, I just 'know' as the new owner the condition/state of such components? Piece of mind. I like to take good care of such stuff. I care. Ha ha. Maybe it's also a good time to have the reeds/reed assembly replaced as well, while I'm at it. Same question---what all is involved in a carb 'rebuild' and where/when/why might I want to replace the reed assembly as well?
Look, I don't want to 'waste money' and 'rebuild just because', but since I have the motor completely apart, I figure it might not be such a bad idea, either. Thanks.
