Frankie's replacement - FXR/GP100 hybrid

[Number One]

then we can sit about saying "nobody puts Baby in the corner" (her name was Francis wasn't it...? )

LMAO!!!! YESSSSSSS

[Slingshot]

Update: Dropped the GP100 out of Frankie last night, pulled the head off as I was interested to see what a seasons worth of thrashing would look like.

I was really surprised, the piston barely looks run in. I'll post some pics of it later on.

Hey Slingy,

Is your FXR frame still bare?

I want to see if I can get a swingarm from one to fit into Lady P's RGV frame as was wondering if I could borrow your one.

If it's all assembled and/or rolling then don't worry about it, I'll just do some measuring if poss please

Cheers,
Nudey

The swingarm & frame are together but no wheels or anything are attached yet. Come over one night this week if you want to have a look, give me a call at some stage to organise.

That would be great
Will do, Cheers

I started stripping down the motor tonight, I've basically stripped everything off and will see if I can split the case tomorrow night.

I think I have made a fatal error though, when I took the crank cover thingie off, the rotary valve came with it and so I didn't get a chance to put some marks on it so I could line it up in the same place again. Oh well, I'll have to figure that out when I'm putting it back together.

Good fun.

Anyone got any tips on the best way to 'wash' motor bits?

Kerosene. Petrol. Dishwashing brush.

Gosh Slingy one all that talk of stripping got me all hot and flustered

[Slingshot]

Kerosene. Petrol.

Mixed together? Do you want me to drop the flywheel puller around?

[Slingshot]

Here's a photo of the ignition. I think it's probably from the GP but it's been altered. According to the Haynes manual, it should have points, etc.

Interesting.

What do I say to that...looks like it's just as well I can't make it tonight

One or the other... No worries on the puller, I've got two.

I reckon you could get an RM80/125 CDI to fit it. Make a big difference, IMO.

There is no problem in putting the rotary valve back.

There is a small notch close to one side in the cutaway part of the valve and this lines up with the crank key and one side of the valve will be more polished than the other, the polished side goes to the cover (outside) side and rubs on the cork like surface during the crankcase compression cycle when you have fitted the valve you should still be able to see the polished side.

After putting the valve on with the notch aligned with the key way you can always check that the valve is around the right way by remembering that the valve opens about 140 BTDC and close only 50 or so ATDC. The difference will be obvious if you turn the motor over by hand and look at how the inlet opens/closes. The motor turns in the same direction as the wheels. play with this and you will see what I mean.

The most common fatal mistake I have seen made on these engines is that people forget to refit the drive pin in the plastic gear that drives the oil pump shaft. Forget this and you have no oil pump. This pin is the same as the ones that go through the clutch springs.

The oil pump was removed by the last owner, so that's good. One less mistake I can make

Good tip for the rotary valve too, I found in the Haynes manual where the notch lines up but wasn't sure how I was going to figure out what way up it went.
