The water pump can be mounted on the lx case but it's easier to go electric.

With a salvage GT the whole harness could be swapped

Same stroke but unknown to me is rod length

Thought about just the head on a 190
You'd have to see first if the oil passages lines up and then if you can get right clearances and the other issues discussed
I think the GT swap is the winner

Yes, though the process is nontrivial. Patrick untaped the GT harness and remade it into the shape of the LX harness.

Added a fan to the radiator today and wired it in.

Did some laps of twin peaks and around the neighborhood to get it warm enough to verify it works. It does, and flows enough air to turn the fan off again even when not moving.

Now I feel like I can safely do some longer tests.

I've been riding it around town and have a few small things to tend to.

1. It needs a fuel pump. On high speed WOT it uses more rule than gravity can deliver.

2. Something is up with the contra spring. The faster you go the lower the RPM goes, maxing out at about 70-75. So, I need to rebuild the driven pulley and maybe install the malossi contra spring.

It's crazy quick though.

Tuned intake
Now that Rich (and Jess) has taken the GPS speed lead I felt I needed to address the tuned length on the intake. The stock intake is about 100mm too short and has a really abrupt curve to it. Carbs work best if they are at the end of the intake so the extended bell intake we used on the GTS won't work.

Took a look at all the mandrel bent aluminum tubing I could find and picked the one with the largest radius that fit within the needed length.

I got the motor mount for Rosebud back today. It is a work of art! The point of the new mount was to extend it by 30mm to allow clearance for the exhaust. But as long as this was being done I figured why not get rid of the crappy rubber bushings and use roller bearings as well as gusseting the area where it connects to the motor.

The motor will still be able to pitch up and down relative to the frame but all roll and yaw will be a thing of the past.

Next step, powdercoating.
That looks spectacular
Good job looks very rigid (bearing-wise)

Hi there!

It was exciting to read about your work. Could you please post some update? Have you managed to hide cooling staff inside the frame?

Again - incredible project and I hope it's still going on!

If there is a cycle salvage near you check out the fans from a Honda cbr1000.

Not sure what year those I found were.

They are very thin...<1".

That were the only fan found that would fit into a Skipper conversion I did in 2008. One also ended up in The 'ninja rabbit'.

Might be just what you need.

What are you doing for a reservoir/expansion tank?

Hi!

Thank you for posting your photos!

How about performance of your Vespas? What are the speeds and accelerations comparing to S125 and GTS125? Can they exceed 100 km/h or maybe even reach 110 km/h or 120 km/h?

I wonder if the radiators can fit space between pet carrier and the body - of course some holes would need to be cut out.

Thanks!
