Hi Andy ,

I've already been in touch with Aria regarding his 1 standard road engine with 102 piston it's also had the head ported he wants £300 for it .
I think the price is very good ,but by the time I've travelled to collect it ( 300 miles there and back )
It's getting expensive and pushing my luck with the wife ..

Also the Ebay items are being watched :)

By the way it was the small end that had failed ,might be down to poor maintenance ?

I phoned BSA Regal yesterday  ,
Standard oversize pistons are available in sizes +0.50 and +1.00 .

0.50 piston £52.92 , rings £16.61 , piston pin £10.37 , 54p clips ,
con rod £41.31 , big end bearing £33.09 , crank pin £26.42
Don't forget to add the VAT.

Many thanks for all your help .. I'll let you know how it goes :)

In my experience, Phil Albutt @ BSA is a great guy.  And the prices are good.  I mean

£50 for a piston?
£40 for a standard rod?!!  Plus vat, sure, but that strikes me a pretty bloody good for a modern bike. 

Anyone know if the corresponding Yamaha pars are the same price??  I bought exhaust rings for the SRX recently.  Same as the skorp bits I got from BSA, but twice the price for the Yam part!!!

Phil did say that they where Yamaha prices / parts .
And yes the prices are good .

But when it's all added up ,crank pin fitted ,gaskets ,re bore
your looking at the same or more than a replacement engine depending on what you pay for it..

So which way would you go ??

If you rebuild it, at least you know whats inside, that said if you buy another engine you could recoup some of your costs by selling the old cases/head/crank etc on Ebay.

So which way would you go ??

   

Personally, I'd wait, and look around, save, then pay the price and buy a complete race motor (or hot road motor), and bolt it in.  Preferably with carbs, less set-up hassle.  But thats not everyone's cup of tea, and will be pretty lumpy...  However, I actually enjoy commuting round lndon on the skorp, with a big lumpy hi CR piston, lumpy cam, noisy carbs etc.

Phone martin sweet at slipstream tuning.  He often has good stuff on the bench.  Its not cheap, but a standarrd motor would be..., I dunno... £250?  More?  and thats used, maybe thrashed, and standard.

The cost of parts sometimes just doesn't justify a rebuild...

ie. to do a valve on the SRX cost

25 for the valve
25 for the head gasket!!!!
About 20 for all the valve seals
About 10 for the 2 exhaust rings
plus vat
plus postage...  not much off 100 notes.  For a 25 quid valve!!!

But its a good motor.  When my first SRX motor gave out, I stripped the top end, and peered in at the knackered 5th gear.  I kept it, as it could still be rebuilt, but wasn't going to pay daft money in parts for what is only a standard motor.  I ended up buying a complete 400 motor with carbs, plugged that in and used the bike for another 2 years.  

Re. the  skorp, I have Slipstream receipts for 1300 quid.  Daft money, not spent by me.  Thats built up from scratch, and repairing all the damage due to a sheared crankpin.  And thats still only a 660, plenty of room for improving things with a big piston and flatslide carbs.   So NO WAY would I sell the bike with the motor.  The thing is so ugly, I'd get about 500 quid for the whole thing (I paid 650).

But you must ask yourself if you need more power.  Otherwise the money is wasted.

(then again, I hardly need it for london, but it makes me feel good, so maybe disregard the last comment!)

Also (this is always my dilemma), can you not renew the bearings etc when you're in there?  Will you put the standard cam back in?  Why not flow the head while its off....

And then can you live with the fairly crude standard chassis, with your "bells and whistles" motor??! Is an extra 10 horses worth all that cash??

And at the end of it, you've spent a *fortune* on a bike, which is still only an MZ (to most folks eyes, not mine!), and is still only worth 800 quid, and puts out 50 horses instead of 40-odd.  A money pit, but we like that in this club...!!

My advice is get a cheap standard motor and get your use from the bike (ie reduce your £s spend per mile ridden).  But thats probably not what I would do...!!!

The choice....  (as they say on telly).... IS YOURS!!!

Cheers, let us know!

Going to contemplate my options for a week or 2..

If I go for a semi race engine it would have to go in the sport ,
Just for testing  :)

Probably rebuilding the engine a later date to keep it as a spare ..

Still totally undecided ..

I've just come back from the sea side !

With a XTZ engine in the boot :)
It's had a 102 piston fitted and the head cleaned up ,
But it has never been started since the fitting of the new piston .

I blame Andy ...

Yes It's Aria lanes motor .
He's a great bloke ,could of chatted all day ,also he runs his Renault on a cooking oil and diesel mix ,
must be something to do with racing ?
 
I've no need to throw receipts away ,
She came along for the ride and knows how much I've spent  and saw the sea ! ( 1000 brownie points )

M25 was like going banger racing in a pond ,
Saw a least 5 accidents or should that be attempted suicides ,some total nutters where out on Sunday ! including me .
I did manage a nice piece of aquaplaning in the fast lane ,scared the Sh#t out of the wife .

Just need to sort some decent carbs out to go on it ,
I have a pair from a DR ( I think ) that need moving closer together and a spacer for the inlet rubber made to make them fit .

Who doesn't use 'veggie' mix or straight these days? The road past my place smells like the arse end of a 'proper' Manx with worn rings!

Sorry andy230, but you know what I mean!

Ciao, Bill
