Re: Motorcycle build 250 tips

Thanks for the comments Tiny,
The head and barrel are hi temp wrinkle paint. That bike (red & white) is for the street.

Yeh, gearing is a little mysterious - i've read lots of different recommendations and used a bunch of calculators. So i'm taking a few different options.

Cheers
Darren

Re: Motorcycle build 250 tips

Thanks Brad for clarifying. I was getting confused between 'gasoline' and 'fuel'. Also been looking at Bonneville bikes that seems to be working on different rules. Standard In line gasoline petcock valve and cut off lanyard sounds good. * 7D3 says the max overbore is .508mm. I was planning .5mm so ...

Re: Motorcycle build 250 tips

Thanks Staly'ie - i'm with you brother. Hard tail and low. Some more question: Remote fuel shut off. I s there a good local product available, or is it a matter of cabling a lever to an in line valve. I see the Bonneville guys use a spring loaded thumb lever on the bars. Any simple solution? Front d...

Re: Motorcycle build 250 tips

Re: Motorcycle build 250 tips

Hi Pete, It's a 1980 XT250 single cylinder 2 valve. Will be fully customised to race and look nothing like the original!. I normally build cafe racers (5 to date). Like the challenge of the salt - should be an experience looking at the You tube videos. If all goes well in 2017, a turbo will follow. ...
