Is that Mal's? Lucky boy

However, how are the authorities on chromed front ends. Last I read they had issues regarding steel becoming brittle over time, once chromed. You could get round it it you proved the process was done properly with a full engineers report; but you wont get that from china where those forks are made.

I'm assuming your running the pre-'69, rules due to the frame but I think this rule is retrospective

I brought it up with an inspector a while back and mentioned that nearly all steel fork legs are hard chromed with no engineers report.......he didn't have a reply

Considering all girders and springers were chromed in 70's and are still holding together, sounds like humbug to me. Same as engineers saying that stock front ends cannot handle rake and extension, yet actual practice proves them very wrong... aside form bad welding and poor workmansip on after market stuff... but that's a different story.

Yeah Mals!
I think (and don't quote me) that the chrome thing is more for cars with made up wish bones/radius arms or whatever you lot call em, Hydrogen embrittlement is the problem after Chroming which causes the welded area to go hard and possibly crack unless it's been treated.

As you say Chucky, all forks are chromed......

Cheers all

A nice gentleman by the name of Zoid gave me his 650 V Star and asked if i'd remove all the carby nonsense and gubbins under the tank, make a manifold and fit an SU....well how could i say no!!
Here is the finished article.
Click on the pic and it'll start the vid.

Cheers all.

Suppose 1 would work just as well on a parallel twin too, mini was only a 850 wasn't it? Great job PC.

It's off a 1000cc Mini.
Just needed to richen up the mixture considerably from the factory settings and she runs very well.
I'm sure Zoid will update more as we go.

A mate of mine in England has one on his GS1000 and says it runs better than the standard carbs!!

Cheers

Yes indeedy . . I have spent most of the day 'fiddling' with things. Took the tank off to 'fiddle' with the throttle position sensor as per my local Yam dealer's recommendation, and decided that things needed tidying up under there. Did a bit of rewiring, trying to reduce the bulky factory harness, and cut off a few (now) useless brackets that held the original air box etc in place. Anyway, after many 'd'oh!' moments, I finally got to ride it this arvo, and I gotta tell ya, it goes like a rocket. XVS650's aren't known for their performance capabilities, but I swear it picks up much quicker with the new carb. Not bad considering the minimal adjustments I've made to it straight out of the box. I don't even know what needle is in it. Just goes to show that a bit of Brit low tech (PC AND an SU carb) can produce wonders! Cheers all . . and thanks to Tex as well.
