640 adv,time for some tlc

Had this motor done 60k?
Is that about the right time for a rebuild ?

Don't think he found much wrong inside the motor, but I'm sure he'll be back soon to describe what was knackered and what was good to leave.

Cam rollers are prone the early failure, but thats a well known issue easily sorted.

Yes JB, 60 k
Not a lot amiss really,apart from the the bits mentioned in the the thread.
I recon it would have gone 10 to 20 more before issues,,,,,,,,
But it shows that the motor is a good thing.not in the bulletproof realms of of a rotax 650
But predictable IYSWIM
Good oil and regular maintenance will see a 100k lifespan (if you don't kill it)
Total £££ for the motor will be @ £1200 in parts
I have gone a bit overkill but as stated previously,I don't intend doing the job twice,and I'd be be gutted if I rebuilt the bottom end to have it drop a valve and scrap the motor

 

[JohnnyBoxer]

Thanks
Looks good

 

[mikeyboy]

Thought I'd turn my attention to the rear suspension so I can move the bike around,
Out with the old

 

[mikeyboy]

That's this weeks pocket money spent

 

[mikeyboy]

Bearings in

 

[mikeyboy]

Seals next

 

[mikeyboy]

New bearings ,seals and pivot

 

[mikeyboy]

Wonder if I'll be able to touch the floor now

 

[mikeyboy]

Rebuilt the rear caliper and back on its wheels

 

[mikeyboy]

Loosely fitted the subframe and airbox

 

[mikeyboy]

So I can get a better idea about the plumbing of this

 

[mikeyboy]

Took timolgras sound advice on reinforcing the subframe prior to powder,

 

[timeandtide]

Have to say. . . . I think he knows what he's talking about!

Engine hasn't been blasted,if you mean that housing?
Regards the frame I washed the old filter and screwed it back on,all of the oil ways in the frame where capped off with plugs,then all removed and masked prior to powder

 

[mikeyboy]

Few more bits on!

Any Exhaustive Suggestions?

Hope you don't mind me butting in Mike?

I would like to ditch the original silencer and fit something lighter and with more character

Is there anything out there with a link pipe or has anyone got owt used for sale?

Dam fine looking bikes these and I love the way they are screwed together (competition like)
