Aye Michael,

OH! Really? Hovering mudguards and all!  ;) ;) ;)

I'd be willing to post up your images or give a bit of tutelage, if you would prefer?

Crack on, Bill

Project Progress / A DIFFERENT tracker 🙄
« Last post by Moto63 on May 29, 2025, 03:42:11 PM »
Having bought the Honda cb250rs from Kev(Berlin) last week, I’ve had a couple of small outings on it. Lovely bike, definitely as good as remembered mine to be back in the early 80’s.
So....Why not build a lovely little rs250 street tracker🤔  I already had a few RS bits kicking around in my garage. So I’ve decided I’m going for it. The big thing I need is an rs250 engine, no immediate panic as I can use the one from Kevin’s bike as a mock up for the time being. I’ve already gathered a lot of bits to get a rolling chassis. I’m taking a lot to be soda blasted next week. Then the tug welder will be getting some use. I’m afraid I don’t know how to post photos. Especially now my go to man Mathee has generally left the site. He used to do them for me.
I fully intend to have this one finished within 5months, ready for winter...oh and hopefully the Stafford show 🤞
Cheers, Michael

Aye Ian,

Thank you posting, the stand appears to be safer than some of the "lift and fly away" stands fitted to other machines, with a gust of wind causing mayhem!  :(

As for the Electra ......... fettling, fettling, fettling, ad nauseum!

Good health, Bill

I know you're all waiting with bated breath to see how I'm getting on....

The good news is that the correct bits seem in decent condition. The bad news is that many bits are not correct. So I have to either find replacements, modify / make what's missing or some combination of these.

For instance the back wheel had a 5/8" diameter spindle whereas the correct one is 1/2" diameter with flats on the end to accommodate the snail cam chain adjustment - which in itself is a nice piece of design. I magaed to get a NOS spindle from Yeoman's Motorcycles, an old-time breaker, and the snail cams from Draganfly following which after much trial and error managed to make appropriate sleeves and spacers to line everything up.

The major task has been using a Kawasaki prop stand as the correct ones are totally unavailable. These stands are great for one-offs and this is the 3rd one I've used. Below is a description of what I had to do to make it fit.....

First of all I needed to make an attachment to the chain stay. I bought two chunks of aluminium alloy, one 60mm x 50mm x 19mm and another 60mm x 80mm x 19mm.

I then bored and tapped four 1/4" BSF holes to clamp the two halves together then held the lot in the 4 jaw chuck and bored to just over 7/8" to suit the chainstay. I then took .050 off the inner surface of the back plate to ensure good clamping.

On offering up I could estimate where the fixing holes for the Kawasaki satnd needed to be so could drill and tap 3/8" Cycle (yes should really be BSW into alloy but don't have any Whit taps). Then made studs to attach the stand. I needed a couple of spacers to clear the locknut on the stand.

As usual the jaws of the stand had spread leaving a lot of play but I managed to close them up to reduce this. The total cost was about £12 for the stand and £6-odd for the alloy, plus various bits and pieces from the scrap bin.

I've now taken the bike off the lift and after some fine adjustment and final tightening the stand looks and works well.

Here are some pictures:

Thanks for the links Martin. I think he’s tried approx 15 different UK outlets and not one have either in stock. They all give the same answer. They’re expecting a delivery from Italy anytime soon 🤷???

As always, brilliant and concise advice Bill. Some of which I personally will take, store in my head for any future builds I do.
Yes.. best of luck Joolz. Keep us posted 👍

Aye Joolz,

It would appear that instead of using lock tabs for the rear sprocket nuts, Honda are now supplying NUT, U, FLANGE. 10MM, #90304GBL003, Replaces #90304GE8003

These are available from David Silver and I have posted the link to their parts list below:

Honda_XBR500_rear_sprocket_lock_nuts_#90304GBL003

At £3-77 each, including VAT, they appear to be about the cheapest place for the OME nuts. Fowlers have them in stock as well at £3-86 each, including VAT.

I have looked on Simply Bearings, but they do not appear to stock this type of lock nut.

Whilst the OME are not the same as Aerotight nuts, the design appears to use the same locking principal, but there appears to be little advantage in price. if you used Aerotights, rather than the OME #90304GBL003 nuts, the Aerotights do not have the bottom flange to spread the pressure on the sprocket more widely around the stud.

On no account would I fit nyloc nuts as an alternative, as they will slacken, with the vibration. Alternatives would be to use good quality M10 nuts, drilled across 2 flats and after cleaning and applying a nut lock liquid, torque to the Honda specification and then lock wire all six nuts together. Another method would be to cut paired flat tab washers, as were fitted to Ducati singles and I suspect many other machines.

Personally, I still use the nut lock and paired tab washer on the Ducati and nut lock and Aerotight nuts on the other bikes. Making sure to torque to the OME recommendation, or that given by any good engineering/fastener supplier guide.

I hope this gets you sorted and out and about Joolz, there is nothing more frustrating than being imobile for the want of a couple, or 6, in this case nuts!

Good health, Bill
