Thanks,

Cj look about for the older 175Agi bike cylinder too, I found them much easier last time was looking for CT175 top end.

Cough cough... I'm pretty sure there's a CT2 cylinder in the large pile of parts that's at the GMC Manor, awaiting collection by Tim...

I am actually looking for a CT2/3 cylinder to go on an early AG175 that I have.  From the basic info that I have been able to find, the AG175 produces 11HP and the CT2/3 16HP. I want to check the porting of the CT cylinder as I am sure that is where the difference is. Then I will rebuild my AG175 enduro bike with the CT top end and hopefully have a Aggie that is capable of pulling top gear.

That would be the pile of parts that I would be tripping over if it wasn’t for someone else’s bike that’s been left in the way

Col, the AGs also have more restrictive airboxes, and different exhausts. The difference won't (just) be in the porting.

I will be altering the intake to just a single airfilter instead of the standard twin filter set up to get a better air flow. I am also thinking of making up an expansion chamber to suit the CT porting, although that would be a dead give away that it isn't a stock Aggie, so I might have to find and fit a std CT pipe (the average punter wouldn't pick that it isn't an AG pipe).
