No, no, it needs a ported big-bore kit, tuned expansion pipe and a bigger carb

Rear-sets and clip-ons ...

I'm sure that cable operated drum brakes would cope just fine.

Or I could go the whole hog and see about grafting in one of the 640 cc twins currently languishing in the Ski-Doos?

It might be an age thing, but there's no way I'll be paying over a grand for a drum brake no matter how pretty it is.

If braking was an issue I'd swap the front end and have discs. However, I reckon that the existing drum will be quite adequate for the staggering 28hp I'll have on tap.

Believe me it was not a serious suggestion !

I know, and if you're building a special it'd probably make some sense. I'll be happy with something a little different to use as a commuter which is why I don't want to chuck a ton of cash into a period correct, rivets counted, no expense spared creation.

Once this is running I'll get rid of the SV650 and enjoy some ring-a-ding-ding. (I'd say relive my youth, but it's a 250 two stroke not a magic wand.)

Probably worth mentioning, but I didn't mean that I was just going to close it back up as is. I was referring to being happy that it didn't need an over size piston and boring to suit.

Once the barrel and head have been stripped of paint the bore will get a light hone, new rings (if available) then the piston and combustion chamber cleaned. Then it'll go back together with fresh oil.

Nice . You do as you like , it's your bike !
Anyone else who thinks It should be done different , should show one they've done earlier .

@redlig was just expressing an opinion rather than having a pop, that's how I took it anyway. Which is all good, it's a public forum after all.

Glad you took it the way it was intended. It's difficult to offer " advice or comment" without upsetting the guy with actual oil under his nails. but sometimes the rubbernecker see's things that are not obvious or have already been decided on. My problem is that having spent 20 years doing that at M/C dealers , as an occupation, it's difficult to always stand back.

True, and it's always difficult to get across what you're trying to achieve (budget, use, etc) with a project/job without writing an essay and boring the bejesus out of everyone. But if you don't give the full story the condensed version can invite comments because people can only work from the info provided.

Not sure whil have the hp to overcome the inertia

 

[Cato]

A roller at last.

Now it's all in place a twist in the swing arm is visible. Only 5 mm at the spindle though so easy enough to press out.

Remove, chock, clamp, squash, refit and it's back to where it should be.
