Just want a quick opinion

Hey I just found out I need to do a top end rebuild. The crank seals are not what failed to cause this but how many of you would replace them anyway? Just wondering

[apeik]

If it's apart, drop the cash and do it, otherwise you may get halfway through a season and be doing it, not a bad time to check out the crank and get it welded if you have mods. I should know i seperated a crank last season, busted the drive side crank bearing and took the crank seal with it. Ran it lean on the right side and put a scar in my cylinder. Milage may vary, Good Luck.

thanks for ur opinion. I agree it's cheap insurance.

if you dont mind splitting the cases its not a bad idea. good time to check bearings as well. they tend to be hard on stuff when they fail

[spurdy]

If it is already apart, I never re use bearings or seals. Too much time, effort and money to do the same shit twice over a few bucks (not to mentin that a leaky seal or bad bearing can cause the repairs to more the second time around).

Wait a minute if u have to split cases to change them than I'm out. There's nothin wrong with the ones in it. I thought I could pull the flywheel and maybe stator to change that side and clutch cover and what ever else to her the main drive gear off the other side. I'm not spiliiin cases

gotta learn sometime! its not bad to do and theres a few guides and even a video on here.

^^^^^LMAO.....It's not that hard.

It's the bikes first overhaul. It's not that I can't or need to learn. U guys say the case has to be split I'm assuming they must install from the inside. I dident know that I thought they could be done with engine on bike. I don't have time to take it apart that far just for preventive matnince. If it was a older bike that had been running a long time I sure would. But mine is a 05 and it the first overhaul so if I had to split cases I'll just wait and Make sure it passes leakdown test after I get new top end assembled. Thanks for the info

The seals are grooved in the middle therefore you have to split the cases to remove and replace.

My last reply dident come out like I mean. I dident know cases has to be split to replace crank seals. Mine will not b that far apart. So disreguard my question but I did gain the knowlage of the fact u can't just swap them out so thanks for that.
