bike weight reduction plan!

I might have gone too far removing excess weight?

It's gonna be loud, and probably run a little lean.

Just push the "Easy" button!

Are you going big bore? I assume not since the piston still resides on the rod. But man, just think of the added TQ with the BB Kit!!! Not that a 525 is a slouch but more is better! Right?

I think we should all vote on it!

Big Bore or Not??? I say big bore since there is no added labor from where you currently are on the Teardown, other than removing the wrist pin from the piston and installing the new one, I mean High Compression Hammer!

Squeeze it tight before you light!!!

I say put some big tires on it with more air volumn, then mount that big fan on the back and take it to the florida swamps. show those air boat guys a thing or two.

you could replace that chain with a heavy duty zip tie to loose a little more weight...

why did you leave the front tire and forks on? you can just take them off and save even more weight by only riding on the rear tire.

I'd say that piston is as light as it will get, so you can put the motor back together and look elsewhere for weight savings.

It looks like an aluminum lolipop.

That would be this anthill I have in the back yard. It's not big but they sure are industrious and ambitious.

I thought the same thing, it tasted awful.

Is it just me, or did you take the timing chain apart?

The setup looks an awful lot like the honda 450 motor, so with that said I've taken them apart more than I care to have and never done that? KTM could, or I should say "is" knowing KTM's different approach, doing things differently to easy in servicing?

Please fill me in? I've been thinking of picking up a KTM 525 quad and its serviceability is something I like to know about. That sure would make top end servicing a piece of cake!

Oh, is the head ported? If not are you going to?

See the attached picture, you can see where the cam chain passes through either side of the head but it's solid in the middle so to remove the head you must break the timing chain on the 525. There's no clip so you must grind the pins down and replace the link.

So far it's shown to be an easy bike to work on but I cannot, as of yet, say it's been perfectly reliable.

I'm not doing any porting or polishing, time isn't on my side for this repair so I just need it running.

I have a chain tool if you need it. For breaking chains, pressing in clips and side plates, and riveting the link.

that might be useful. unless you're thinking of the chain tool you own that's in my toolbox already.

Huh? Do I own two of them?

I did think I had a different one when I was putting the chain on the RVF. I was looking for it and found this other one and thought it looked different. I did the same thing with tire irons and Cil. I called and said "you got the other set of tire irons?" Turns out he did have them. Must be losing my mind.

I see. That is messed up, IMO. for in the field repairs that just wouldn't float!

the honda head allows for removal without breaking the chain.
