it seems so!
I am deleting the spam folder on a regular basis without checking every mail.
Would you please be so kind to resend it to me and I will watch out for it 😉
To upgrade our transport and camping capabilities I’ve bought a Ford Transit.
Diesel, 100 HP, air conditioning, auxilliary heating, an Airline rail system in the floor and an integrated wheelchair ramp !
After some modification we can transport three racebikes easily now.
Big advantage is that we don’t have a general speed limit anymore as it is…[Read more]
final compression after the piston was “manipulated” a bit (pockets for valves, pinch-off edge(?)) and cylinder foot gasket (1mm) and cylinder head gasket (1mm) are used is 9,57:1.
This engine runs with stock LTD ignition (pointless) and single spark plug per cylinder.

I’ve tried this before and wasn’t successful as these things are more expensive in Germany.
I’m interested in two sets of these !
Questions: The stock sleeves have to be removed, the cylinder block maschined to larger diameter. The new sleeves have to be maschined at the outside to fit into the cylinder block and at the inside to match…[Read more]
thank you for your interest in the engine tuning.
Well, let me sort some of your questions:
The major frame mod at the “Vienna” is to cut the rear frame off and also the rear cross-tube out of the frame. The cross-tube was in the place where the silencer is now. To gain stability of the frame again, I’ve welded angled cross-tube…[Read more]
welcome back and congrats to your very nice Twin !
I am sure it is a lot of fun in the mountains with it 😉
PS: In regards to engine tuning I can support you with some information. On our german Z750Twin community website there is a portrait of a Twin I’ve bought just last week !
Manfred built it and there is a lot…[Read more]
Hi Lonesome Twins,
the stainless steel exhaust headers arrived and it is hard to cut half of them away. That is needed to find the right angle to the collector. Only three parts of the exhaust are missing now and a special exhaust part that separates the collected exhaust gases to the two mufflers is ordered in UK !
Looks good to weld the…[Read more]
I will get a new fuel cap welded into this tank, so don’t need the mentioned cap anymore.
Got a pair of chinese KOSO PWK 34mm flat slide carbs and larger intake boots to mount them. Fits quite well and I will see if this small engine will take “food” from these large carbs 😉
Still a lot to do 😉
BTW: These two carbs weight is 900…[Read more]
Well, little progress made. This bike gets upswept exhausts as well as the “Vienna” has it.
Looking for a rare fuel cap of this tank:

Hi Lonesome Twins,
as the GPZ305 ended her race career after just one track event
I had to look after a replacement in the class below 55HP 😉
It will not replace my “Vienna”, the Z750Twin race bike.
I’ve found a massive modified Z440 and some of the mods…[Read more]
welcome to the Lonesome Twins and thank you for your introduction.
Looking forward to see pics of your Twin.
Best regards, Michael
there is Peter in Germany who is making down tubes from stainless steel.
They can have different angles and diameters at the rear end to match your desired silencers.
They do not have an interference/connector tube from left to right.
Let me know if you are interested.
An unpolished pair is around 280,- Euros, a polished pair is around…[Read more]

even if there where only a few bikers and bikes, there were very nice people and bikes.
Well done !
Well, I didn’t manage to fit the tuning engine into my racetwin by now, so I will do it this winter.
Had the last track days last week and besides the GPZ 305 I rode my “Vienna”:
battling a…[Read more]
Hi Lonesome Twins,
I had some fun on the track with this little GPZ. The girlfriend of my son loves this bike and she wants to make her bike driving license until spring 2020. So this will be her first bike and we will modify it to be roadlegal again.
Here some pics:

Hi Lonesome Twins,
as I can’t start a thread in any other forum I do it here 😉
Sure some of you know me and I’ve introduced some of my Z750Twins already.
This time I just want to show you what I’ve did in the past two months.
A friend of mine wanted to modify a 1983 GPZ305, also known as EX305.
He lost the momentum and wanted to get rid of it,…[Read more]

nice little Kawasaki you have !
I would like to attend the DGR, but that Sunday is the last day to prepare three bikes – to have fun on a racetrack the days after.
Wishing you and the Gentlemen and Gentlewomen all over the world a great day and many/much (?) donation(s) for a good purpose !
