Good stuff!

It happens due to the ethanol content in modern fuel. Those are made of a type of rubber which resists it.

Be careful with the plastic T parts anyway, but they'll probably be fine.

If you can, get a Vessel brand or other JIS PH2 size screwdriver to take the carbs apart. The screws are fine until you go at them with a normal European Philips driver, that's when the heads round out.

These guys make better than OEM seals, assuming your plastic parts are ok.

one more tip, Graeme France (find Graeme France racing on Facebook) has made a batch of replica gaskets which fit well. The eBay gaskets don't really line up right.

GF is also a good source of used CBR parts

Hi Ali, welcome!

You can use a cover off a cbr400 or cb-1, I think cb400sf covers also fit but I'm not sure. Cbr600f1 covers are similar but use a bigger generator so unless you swap all that stuff too, it won't work.

If you get an OK one, you can smooth it off and fill any marks with epoxy.

You could get replica chrome caps but looks like no more.

Does anybody know if its possible to get a rebuild kit for the rear shock thats either aftermarket or oem   Sent from my iPhone using Tapatalk
You can fix anything with a big enough hammer, however a shock absorber needs to be gassed with high pressure nitrogen and that's a quite expensive hammer.

Easier and cheaper to get a blackbird shock and 900rr sidestand.

I think a lot of them are broken off just there, but the exhaust never seems to suffer because of it. Maybe the bike vibrates a little more than it would? Hard to say.

Wow... listing shows 72000 miles. I paid $3300 for mine, and it only had 4000 miles.
Not sure what 3000 Canadian works out to in US $$$, but seems way high for that many miles
2,300 USD. Idk if it's good or bad but looks like much less on paper than 3k.

Same lever pattern as period cbr600&900 models.

Everything is possible with a big enough hammer. But I think that idea takes a pretty big hammer. That's from a guy who has nc29 arm fitted.

Would be a whole lot easier to just make better spacers for the wheel you already have.

First thing to say is, are you doing a restoration, or are you putting it in boxes to sit on a shelf? These aren't the same but one can quickly turn into the other.

I'd leave fuel in the tank, but spraying oil around seems reasonable. It'll be easier to paint empty though. Bear in mind that the oil will then run through your engine though, don't overdo it.

Over time left disassembled, the water seals in the engine will perish. Damhikt. Seals in the carbs will dry out (be fine if you used the viton type from Thailand). Fork and brake seals, plus tyres can all dry out over long term storage.

Never try to paint a bike still assembled. It'll look horrible. Take it out, clean it very thoroughly and paint the whole thing in black or silver engine paint, mask the covers but don't need to be too precise. Then remove the side covers, strip all the paint chemically, and put some enamel or powder coat on. Refit with new gaskets from Graeme France and some stainless bolts.

Front engine mount bolts will almost definitely be stuck and, if really corroded, can crack. Go straight in with the big guns. Drip penetrating oil in over as long as you can, get it really hot to expand the alloy off the bolt (this is key), and hit it with an impact gun rather than a long lever.

Lovely  Cool People are going mad over little bikes at the moment, in the UK, they're paying up to 6K for restored 1970s Yamaha FS1-E sports mopeds and other classics of the time. I'm a "nevermind the quality, feel the width" type of guy myself and it always seems a lot of money for little bike to me but I see the attraction.
I had an MSx (Grom) for a couple of years. Little bikes are cool Smiley

Looks like you're one busy weekend away from a running $1500 bike? Someone gets a bargain here!

14  General Category / General Motorcycle Discussion / Re: Brand new old stock on: June 18, 2018, 02:26:03 PM
That bid price is well below 1989 MSRP with inflation factored in. Mount some new tires and ride off on the new CB-1 you always dreamed of back in the day.  Grin
Not to mention, what does that money buy new? Puts you half way between a cb500f and cb650f. Neither of these have gear driven cams.

The braided hose isn't stock, but it looks like a good solution to the OEM formed rubber hoses going brittle.
