WANTED XS 650 Engine

[SON]

Thanks but not what I want,
I have my Mule chassis With Jemco/ Ohlins /19"s
Just want a built 750/850 motor as I don't have the time,
I have a set of SP pistons and a stroker crank and 5 tradesmen Mechanics capable of building it,
just not the time,

[EML]

When do you need it by?
I have an 880 but was hoping to do one more season before looking for a Norton to make the Wasp original.

[SON]

Wanted it for the Sydney Flattrack Series,
The Mule Chassis is too nice to put a stock engine into,

[EML]

So much for the add a twin class and you will bring 500 people and promise the world! Twin class has been added.

Yep, it's official that the Penrith club have added a Twin's class to the program for round 1 of the Western Syd DT Series on the 24th of March.
Their policy this year is for pre entry only and they need to be rec'd prior to a week before so unless the numbers don't show up it may not actually happen on the day and if that doesn't happen, they may not get included for round 2.
If it helps with numbers and anyone out there has a Twin anything they'd like to see getting around I'm prepared to throw the leg but be warned, I'm gunna look like a travelling marshal, for now.

Cemoto I usually associate Bultaco owners with intelligence .....
1st thing I sponsored the Series,
2nd thing I am giving 3 or 4 bikes to guys to compete,
3rd I will make a few calls to some friends to get the event plenty of media, because I want it to be successful
I will also do a few other things to help,
.
I am sorry that it is on the same day as NZ SGP but I have some meetings at that event that I must now attend,
You can criticise all you like after the event, but you don't get any creditability doing it before hand,

[EML]

So Son are you keen on an 880 stroker motor?

[SON]

PM sent

[SON]

Thank you

[SON]

My 880 Stroker arrived today, thank you very much,
The guys opened it and studied it particularly the clutch,
Can't wait,
I also bought a C&J Flattracker with the change so I am more than happy.

Great to see a real honest positive ending here!

880 is an unusual size for a stroker, is it a (81mm) 750 kit with an 85 mm crank?

[EML]

Not sure Matt the Millionaire, I was told it was an 880 tho have nothing documented to confirm it. I think Popeye measured it when we rebuilt it and Serco provided the pistons which had to be cut so as to not hit the crank. It has a 6mm plate under the cylinder which is exactly the width of one timing chain link. Therefore, when 2 links are added along with the plate, the cylinders, head et al go up the same amount and the cam timing stays the same. No need to cut and shut the cams.
I have seen inside, when we did the gearbox over Xmas, and it looks to me like the crank pins have been moved so as to give the different/longer stroke. 
It also has the clutch moved to the r/h cover though it's a bit wide-shouldn't be a problem for dirt tracker and it gives the better option for larger/small countershaft sprockets.
It's a good fast motor but suffered from lack of 3rd gear through most of last year--Conondale and Wyarralong nats. That's been fixed now.
