MV 350 in Sydney Auction on 24Jul11

All,

Shannons will hold their quarterly Sydney auction at Homebush and the lots include this MV 350 http://www.shannons.com.au/pages/auc...PXAF71C3390A68

I had a look at the bike, it is well presented, however I'm no expert on these 350 twins.

I did make the following observations:

It appeared to be oil tight
All cosmetics are near perfect
The gear lever had a flaw, not sure if it was from manufacturing (poor casting flaw) or a repair (not so likely)
It has a right side gear change (a challenge for those of us used to bikes from after the 1970's)
The fairing interferes with the kick start (so push only? no evidence of an electric starter)
There are no air-filters on the carburettor bell-mouths
Tyres apear old but not cracked
Discs have evidence of lack of use too (lever pressures seemed good)

I have no room for this and it really isn't my thing either, so god luck if you're considering it.

Andrew...

Hi Andrew,

I have seen that bike - If were buying it the main question I would want answered would regarding the motor. If original - it is just waiting to fail, the Ipotesi's where built with flawed heads, generally leading to a (catastrophic) valve failure, especially if it has been sitting around for a long time. I have had both engines, heads done on my Ipotesis.

The fairing on that bike is from a 750 I am surprised that it fits, the bike does not have an electric starter so, you must be able to kick start it somehow. The kick starters are quite fragile on those things so, generally if it doesn't start first few kicks, I bump start mine.

The guiding range is $15-$20K so it will be VERY interesting to see what kind of bids, if any it gets. The last Melbourne Shannons auction saw much of the stuff that you would have expected to sell being passed in.
Sign of the times?

Yep Alex, that's what they are saying - $15-$20k AUD is the expected selling range - personally I think there are way too many 'motorcycle investor' dreamers around. It's kind of funny how this rides on the back of a thread I started on that topic a little while ago.

It will be interesting to see what they get, personally I would love it if they got $20k for it for obvious reasons

You know sometimes you get lucky when someone with more money than sense comes out of the woodwork & buys stuff, the problem is people hang on that as a real market value & then after much financial pain find it isn't so.

Here in Sydney we have a company called Deus Ex-Machina, they get clapped SR400 yamahas tart them up, bling bling them, turn them into cafe racers, badge them as "Deus" & sell to the Yuppie scene for $15K & up - yep, they sure do - the real shock comes when these yuppies come to sell these 'unique' bikes & have to take a major bath.

I'll go check my PMs

The starting price, $15,000, seems quite high especially when you add a hammer fee. Auctions like this often sell items for inflated prices due to the auction hype and/or buyers who haven't done their research.

It may also be the case that the 'adviser' as to the bikes value doesn't know the market and puts an unrealistic value on the bike much to the owners pleasure, that is until the bids are far below the price guideline or there are no bids at all.

I sold a car in a Shannons Auction, they asked me my reserve and then created a guide that reflected my reserve. For my sale at no point did Shannons attempt to coerce my reserve, so based on this I'd suggest the owner has set a reserve of about $18k.

I personally have no feeling for the value of these bikes, but as a general rule a 350cc bike of that vintage for over $15k has got to be pretty special.

Head Failure





These two pics show exactly how they can fail and will eventually fail. So even if it has no problem I would still take off the head, and have it re - engineered.

The bike running beautifully is a so much fun to ride, it really does transport back to another era.


I rode mine last weekend with my wife & son - She rode the Guzzi, He rode the Cagiva - I rode the 350s and it was a blast - never fails to leave a smile on my face but that particular one I have owned for 15-16 years

Quite major valve seat failure,

when you say "re-engineered", do you mean grind out the original valve seats, fill the the area with new metal and then cut new valve seats and ports?

Or was there more to the task? did you change the porting and flow with this work?

That head is in my garage, we used NOS head, as you can see from the pitting, the heads as produced have a higher degree of porosity than would normally be desired.

The new head was ground out, new seats were made from a harder material and fused into place, I am not sure of the process, the porting & flow is as original spec - the engineering work I referred to was more how the valve seats built and set into the new head rather than cut into the head from the original alloy. Anyhow, that's the best of my understanding .

normally , in a production situtation the valve seats will be cooled in liquid nitrogen and drifted/pressed into place using the valve guide as alignment to ensure the seat is 100% correct to the guide itself.

however if in a small shop they MAY heat the head then fit the valve seat without cooling the seat. In most cases it is specific type work and most mechanics these days are not tooled up to do the job so will send the head off to a specialist machine shop to have the work done............then charge accordingly.
