I think the 82 SECA 750 I just got needs a starter clutch

I think the 82 SECA 750 I just got needs a starter clutch....It starts fir cold like a new bike but when hot noise from hell starts after about 4 5 trys...IDK what kind of oil is in it and the battery starts it when cold but spins starter when hot and noise...but even after being on 2 amp charger all not the green charge is still flashing....has 20k miles

 

Why would it not do it while cold...the battery in it gets crappy reviews like 2.2 out of 5

 

And if it was the battery or oil would it do it while cold also?

 

Use only JASO rated oil some oils cause problems with wet clutches and starter clutch. Rotella T4 is good l believe. Slippage when hot is because the engine oil is thinner or is the wrong oil .

The clutch just gets worse with heat.

If I were you I'd check out K-Moe's write up and run Rotella T4 15W-40 and hope for the best, but prepare for the worst. Worst case is you have to live with it for a while - it's not like some sort of urgent situation. Just a pain in the butt when the bike is hot.

 

Well I guess the battery is ok ...volts drop to around 10 while starting while cold

 

What is time do the labor this job at a shop... There is a guy here in town that specializes in working on older bikes he will do this but he's on vacation in Florida I won't be able to get a hold of him for his labor time.... That's why I'm asking what should I expect if he tells me 12 hours is that too long

 

Well the classic shop texted me back said around 1500

 

With the engine out of the frame it could be done in a few hours, it is not that big of a job. Do you have the time and knowledge to do the repair yourself or are you too busy hence the shop option?

 

@cds1984 thread on this work will give you an idea of what is involved.

What can or should also be replaced while in there

 

Change the starter chain guide, its old and if it breaks up will affect gear selection, check the oil spray nozzle which should have no marks from the chain. The guide bolts apply heat before removing them to soften the factory loctite. Get new bolts torque to spec 10Nm.

 

I changed the oil to Shell T4 it seemed to help a little

But with all that notice from the starter clutch why wasn't there some shavings in my old oil? And on the drain plug

 

Shavings don't come off the rollers, they must be hardened. Weak springs might be the cause.

 

Think I will see if it makes it though the summer IF it last that long and replace it in the winter

 

I think it’ll last the summer. Mine has lasted several. Just might be a little embarrassing when you’re in a crowded parking lot when the bike is hot and you try to start it.

If it is a problem when the bike is cold, then you need to worry.

If I were you I would change oil again relatively soon just to make sure to get rid of whatever was in there.

 

Yes well winter is a good time to replace it.

 

Jetfixer had the same problem with starting his bike when hot, it still lasted some time before he had to replace it.

 

Starts fine when cold and semi warm...its only when hot

 

You’ll be fine for as long as you’re willing to live with it. I just know that when I stop to pick up a 12 pack of beverages on an 85 degree day that I might get a can of marbles. Eventually it starts after a couple of attempts. Worst case I’d have to push start. Not a big deal. Thus far I have not had to resort to push start.
