Eventually taken delivery of this project which will be my biggest and scariest to date. I wasn't lookin for anything but it came along by word of mouth at a price which couldn't be ignored. Last taxed in 1975 it spent all of its roadgoing years in Northern Ireland. It didn't come with the current style registration document only the old buff number showing only two registered owners from new.
Originally, as you can tell from the photos, it had a chromed tank however money being tight it will be sprayed black in due course. I intend to refit the engine fairings as ,perversely some might say, I think they are quite handsome or is it pretty as its only a 350??
Appears complete with exception of mudguards, exhaust pipe and saddle which I suppose are easily obtainable. The engine was split when purchased and on inspection evidently due to a shot big end. The rocker shafts/ box are also goosed and will need replacement as well as the swinging arm bushes/pin.
Money is an issue with this restoration and is going to take some time to complete but I suppose its in my possession for when circumstances allow.
Other photos show my Velo Thruxton (less head)/ Venom Eng. No. VMT 70LS3 which I am led to believe was built by L. Stevens along with a few others. Anybody know more??
This bike also needs some attention lavished which I suppose should be done before contemplating starting the Viper.
I'll keep the forum posted with progress.

Regards,
Dave Beef.



I bead blasted the previously filthy engine parts contrary to popular advice but spent an AGE making sure ALL residue removed. Worth the effort I think.




Doesn't matter what angle you look at the pile. It still screams mega work!!




In slightly more roadworthy condition.

I know you said money was tight, but is the Petrol tank in sound shape? - it looks ok. If so, i'd hang on and do it Chromed as it was in 1960.

As for guards, I bought a pair of chromed undrilled mudguards for my '58 Venom from renovation spares.


Good luck with the project - it looks like eveything's there. I'm psyching myself up for another Venom this year.

Hi Steve,
you're probably right about chroming the tank. I'll leave that to last and hopefully there's enough money in the pot to have this done. It only seems to have surface rust with no dents evident. I suppose that will save a few bob. Whoever put the bike into storage previously did the right thing and greased the outside of the tank. First of all though it will be out with the worn swingarm bushes. Oh joy.....
Regards,
Beef

I did mine this time last year


You'll already know, but be very careful when reaming out the bushes that the trunnion shaft must be a fairly tight push fit. When I first did it 10 years ago, I was a bit liberal with the reamer and the bushes needed replacing after 15,000 miles. With regular greasing, they should last double that.

I could actually feel the back end twitching before I twigged it was worn/slack trunnion bushes.

Great looking project Dave, I tend to agree with you on the engine covers they give a great period look and like most of the other supposed styling gaffs by Veloce, they were just way ahead of their time.

If you have not already, take a look at Grove Classics new web site, it was recently updated and is very well put together for Velo parts ordering online.

Have fun with the restoration and this is a great addition to yer already impressive classic bike stable.

Cheers Bry

Hi Steve,
I have NEVER seen play anything like that of the trunnion shaft on this Viper. You need to see it to believe it.I cannot comprehend how this bike managed to be on the road prior to been laid up. What method do you use to remove the old bushes? I was considering careful use of a hacksaw or possibly heat on the housing and a suitable drift?
My other Velo hasn't needed this work as yet and is regularly greased.

Good luck in finding a Venom project by the way. Don't seem to be ten a penny now and any that do come up seem to be overpriced in my opinion.

Dave B.

Cheers Bry.

This 'impressive' stable unfortunately only has one bike fully roadworthy and I have decided to put the Viper to bed and finish the others which are 'nearly there'

Dug out Huntmaster which needs an engine rebuild due to a seizure ( snide pistons I believe) and managed to source a fully enclosed chaincase which I am fit checking prior to painting. Not perfect condition as can be seen in photos however hard to find and probably in keeping with the general condition of the bike.

When finished Venom needs main bearings shimmed properly. Last 'expert' who had there grubby mitts on it obviously in wrong line of work.
GOD SAVE US FROM THE HAND OF BODGE.

How's the Venom coming along?

Beef.

Hi Dave,

Plenty to keep you busy for a while then! still a good collection though.

If you are shimming the mains on the Venom yourself, I got a good tip from the VOC Dave Allcock DVD. It involves trial assembling the crank in the cases and inserting pieces of .004 shim stock between the cases to create a gap. Then by measuring the end float on the crank shaft, will give you size of the shims that are needed. You may already know about this method but it certainly looks far simpler than the hold the cases until the bearings start to pinch then check gap with feeler gauge method described in the Velo workshop and service manuals.

My Venom is on hold until the end of this month as I am working overseas. Got quite a bit done over the Xmas holiday, but this was mainly on turning up a set of knife edge rollers for use in balancing the crank rather than actual work on the bike.

Cheers Bry

Thanks for the tip Bry. I'm lucky enough to have the rebuild DVD for the gearbox as well as the engine and intend to use the shimming method your man suggests. A friend of mine and a velo enthusiast claims that you know when the shimming is right when there is a slight nip on the crank when the cases are bolted up which frees off when heated up in the oven. Hence the preload obviously.
I'll give it a try anyway.Failure will only cost a driveside crankcase!!
Cheers,
Dave B.

Yep the trunnion bushes drift out fairly easily - you don't need heat.


Put new ones in with a neatly fitting flanged steel disc in/on the new bearing and one in the other side's bush housing on the frame and pull in with a threaded bar and a couple of nuts.

Stripped Huntmaster bottom end to find disintegrated crankshaft shim leavin 10 thou end float as measured in attached photos. Problems appear to have arose from loose main bearing rubbing shim. New bearing will be glued in with new 8 thou shim in place.
Other photos show crankcases after moderate session with bead blaster. Decided to block up openings with plywood and silicone other than blasting in halves and hoping to wash the crud out successfully. Will still thoroughly clean out regardless but less chance though of disaster.








My best buy to date. DEFINETELY the blasting cabinet!!

Rgds
Dave.
