Back in Game Harris Mag 2

[Allspeeds]

So it’s taken a few years but whilst the romance of racing is still ongoing the lack of a project in my life has been a void I’ve been needing to fill and after visiting the Worship show and seeing some pretty cool machines and some old faces the bug hit, I’m lucky that in my game I can put a few feeler’s out and see what’s comes back and well in this case I’ve ended up collecting this old girl to bring back to life ……..

[imago]

Nice, and a proper engine too. 

[Allspeeds]

In its past life …..

[Allspeeds]

The old boy Eric I bought it off is 70! It’s basically not seen the light of day since he bought of the man Carl who emigrated to OZ in 2003 he was and still is a bike painter hence the many colour changes 

[Allspeeds]

I was pleased to find some bits from it’s previous life, stock top yoke and clip ons but gutted the original Harris half fairing and proper Harris silencer are long gone

Brian McCall (Centurion) in Hexham, Roger Upperton in Leeds, Chris Grumpy1260 in Lincolnshire and me in Redditch do them as a company if that's what you mean?

Whoever does it bearing availability if it needs one/some and the number of times the crank has been apart before will be the big factors in terms of cost and/or if it'll take another rebuild. So I'd suggest the first thing will be to assess it and then go from there.

You didn't mention you can also do this.

Rodger doesn't like to work with cranks much now.

Very few do, I think Grumpy is at a similar point with them too. The costs are ridiculous for those bearings which you can get, it's very very difficult to get hold of a good crank to start with as they're all over 40 years old and you only get three goes at pressing them apart and back together before they're scrap. So there's not much call for it and people are reluctant to pay a big price for something which you can't put a full warranty on because most if not all parts are SH.

The last time I spoke to Mr Upperton about cranks (about 5 years ago) he said that it was normal to need three cranks to build one decent one out of. Plus I think he's at that stage now where he's cherry picking the work he does as he's looking to wind things down a notch or two.

That’s awesome. Love the colour scheme 

[Allspeeds]

Done abit today…..

This is my situation buddy what’s your thoughts quick inspection things feel ok but certainly don’t look it 

[Allspeeds]

Went through all the boxes and found everything to be there

found stock carbs in mint condition to day theve been stood and also some 34mm flat slides grubby but that may of preserved them so that’s good

also found new pistons for fresh barrels bored out to 75mm so il check what CC that makes it later tonight 

[Allspeeds]

Fair scrap pile 

[Allspeeds]

So to my reckoning that’s 1168 kit   Had slight head skim and some porting and it’s got some different cams so the basis for a decent engine is there 

[Allspeeds]

Not all good though sadly the original WP shocker is bin fodder all though it damps the rod is pitted and fucked and the chances of been able to get one is very slim

Don't think you can get the seals for them anymore anyway.

The taper looks decent under the surface rust, so check the bearings and if they're good the next thing will be check it's in true. If that's all good then get the pins welded and the rest is elbow grease.

Oh, and a relatively cheap head upgrade is to get hold of a set of EF (or new aftermarket) inlet valves as they're 1mm larger dia. The seats are pretty meaty so they'll take the cut without replacement.

It'd be worth checking how bad it is as I imagine getting it re-chromed will be a lot cheaper than replacement. I don't know the sizes for the seals, but I'd be surprised if a hydraulic supplier couldn't match them as they're only low pressure rams seals after all.

Is this a service you said you offer?

I do, as do the others I mentioned. Basically whoever you take/send it to on that list will do the same thing, run through the checks to see if it's usable as is, needs work/parts or is scrap.

It might already have the oversized valves in as it sounds like it had a fair bit of work done to it.
