3rd time lucky

[xwhatsit]

Just one greenie

Great little engine (you can take them out to 302cc).

I was lucky.
I fell off on an deceptive icy corner and not in a bog like quite a few others

I bet you don't like icy corners very much after the past few weeks

In a long-running thread about building a CB500RS a member mentioned that apparently you can take the CB250RS/XL250S/XR250 lump out to 337cc or something like that; a 350cc Yamaha thumper piston and a new cylinder liner does the trick.

If you're going to bore it out, do it right


I want a thumper dirt bike something chronic, your photos have inspired me. Taking the CB over gravel roads is a ball, I want a taste of the real thing.

Anyway, you still haven't mentioned how many total competitors! Tell me it was more than 22!?

Even 302cc means boring out the cases to fit the much larger liner.

Mine is only 2mm oversize.

I've got 2 6-speed gearboxes, 2 brand new complete crank assemblies and a complete CB250RS (6-speed) engine as spare parts

Still using the 5-speed at the moment.

I think it was 28-30 riders but havn't got the results yet.

Still, I'm going better than Charley Boorman, I finished my 1st X-Country

Next - Dakar...

*Clears throat*

Offtopic, yes -- but:

You have a 6-speed geabox to suit an RS? Two of them?

If you're ever interested in parting with one of them, well, you know how to PM me 5 cogs aren't quite enough IMHO.

Anyway, enough crap about ancient Honda thumper mills. Back to your normal programme.

Same overall gearing but smaller gaps in between.
The XR500's have the same 5-speed but a hell of a lot more torks.
When I'm changing gears I'd like it so that it wasn't bogging slightly in the new gear.

The box drops straight in as long as you've got the gear driven counterbalancer.

22nd out of 35 starters

Warewolf got 17th somehow.

Hmmm, wonder if he was going faster than me?
