Hello Teezee! It's amazing how small the world is! I personally know the owner of this moto and the cylinder as well. I can tell you that such a huge cm3 (105cc) can not be made without compromise. 55 bore, 44 stroke.

Hi Forgi, I enjoyed the video, sounds good. I liked the photos of making the sleeve and fitting it to the cylinder because its the sort of work that I would like to do too, I hope to make my own special alloy sleeve for the Beast one day.

We are lucky to have the F4, F5 (Bucket) racing class here because it allows a whole range of different people to participate. Someone can take a stock FXR150, fit it with secondhand slicks and have a good bike while others might like to try their hand at modifying something more exotic, which is what I like to do. Our racing class rules pretty much keep everything on a level playing field and that's good.

If you have other pictures of modifying Simson engines I would love to see them posted here.

A few people have asked me to share my experience with the dentist drill I purchased to use in porting two stroke cylinders.

Here is a link to the ebay auction for the item in question:
http://www.ebay.com.au/itm/Dental-La...884b267&_uhb=1

Straight head and carbine burrs work well and cut fairly nicely
Cheap
Adjustable speed
Forward and reverse option
Foot pedal
Angle head uses a different type of bit which I didn't realise when I purchased it.
The straight hand piece takes these carbine burrs: http://www.ebay.com.au/itm/10Dental-...157936f&_uhb=1 and I thought the angle head took the same but it actually takes these:http://www.ebay.com.au/itm/251017043...84.m1439.l2649.
The angle head bits are good for very detailed cutting say if you wanted to remove a millimetre off the roof of a port but not good if you wanted to take a lot of meat out the side of a port. Overall, not to happy with them for what I wanted to use them for. If I could fit the straight hand piece carbine burrs to it we'd be golden.

Currently here are the tools I have below, plus a straight head Ampro die grinder which I use the two carbine burrs in photo two with. These two burrs are great and I think they're burrfect for using on the transfers and the casing but I need something to do the transfer port openings into the cylinder.



So currently I'm stuck because the angle head isn't quite what I want to cut the transfer ports with and I don't really want to pay out $800+ for a CC specialty tool like I probably should if I want to do the job properly/easily.

I just used the low speed mechanical dentist head and ran it off a dremel. Works fine with diamond burrs but only as you say for 1mm subtle cuts.

[F5 Dave]

...and if you bore it in a lathe the wee pedestal is toast.

Any reason you couldn't do it in a mill, with a long slotting drill and the carb body in a dividing head? You wouldn't get the main bore beyond the pedestal done but you could either turn it over to do the other side or just fair it in by hand with a die grinder.

Hahaha, you're a GC. You're spot on. This arvo a mate came around and we looked at it and I spotted that there was an insert that with a subtle grind could slide out. Made a special tool to pull it out. Came out so easy it wasn't really required.


Didn't help much as the shroud is still part of the floor. But Matt noted that you could clamp the carb quite easily and do it on a mill. Clever bugger I sez, then turn it over and do the other side. There will be a bit that won't get reached but will be easy to dremel the thin section to match the other sides.

Thanks it was good advice and would have been super useful, takes the edge off what was going to be my clever post saying that we'd cracked it though.

Great minds think alike, eh?

Or as one of my old tutors used to say: Son, fools never differ.

Thanks ChrisC for posting that, and I had a look at your link to the CC specialty tools site too, and found an interesting page on his thoughts about porting and porting technique.

One of the best tools in the garage is a mate to soundboard off.

I'm good at improving the idea but soso at originally.

Thanks again.

Oh yeah. Last night I was awake and wondering about the slide. I knew I'd have to trim it. But thought maybe they limited travel with different caps. Sure enough a trim will get enough travel.

[speedpro]

Or you could make a little spacer to go under the carb cap, sort of like a spacer under the barrel to lift it.

You can modify them to fit the angled handpiece if the shaft diameter is the same.

Nah you wouldn't bother, the slide comes up far enough to make a ~36mm lift, just the extension of the cap comes down around the cable and limits the slide.

I was thinking about thier modular design using same casting to do at least 3 carbs & thought about the slide & figured rather than have 3 slides (+ x as many alternative tune slides), instead just have three differnet length caps to limit the travel.

This is a porting tool!

[TZ350]

That is a "Real Mans" porting tool for sure ..... ... very clever.

[Drew]

Should the gasket surfaces be clamped straight in the vice? I assume they are gonna get a skim if it's getting port work, but how do you measure your port timing if the heights aren't already set?
