Anyone fitted one of these to a 200/225cc kit such as the Avanti ? I ask as it says it needs no fins cutting to fit it. Just wondering, like.

I am in the process of porting an Indian 200 barrel, and will be fitting one of these and mine fits without machining any fins. Andy

I bought one a while back to fit to an old school 'Yamaha' 200 kit.Back in the day,the DT175 piston for the kit had to have the reed valve windows welded up,so I bought one of the 'Atomic' reed manifolds to save fannying around with the piston!,it fitted with no alteration to the manifold or the barrel,even the port to manifold area was virtually spot on!!

Any feed back on , fuel consumption, acceleration, pick up, top speed what carb how close to panel :D

I've got my eye on one of these but want to keep my airbox.

I have a 25mm PHBL at the moment.

Anyone know if it's possible to squeeze this in where my manifold is at the moment?

Not yet Steve. Only happened to look at it yesterday. Saw the other one they do and then a link to this one. Have an Avanti kit on at present with the larger cooling fins and was getting a lot of spit back last year, so have been thinking of a reed valve to improve that issue & fuel consumption/starting/power spread and then saw the link to this one. Not sure whether its too small for a 225cc. :? :!: :?: Don't like the idea of cutting so much off the fins to fit the other one and can't be arsed to tell the truth. Spending £450 on a top new kit and then having to cut half the feckin fins away is not my way of doing things. :roll: :D May be giving that nice Mr Corrado a call later this week. Do you really have to cut holes in the piston or can you just fit it anyway, if no holes cut what effect will this have?

Mark. Have a look at the thread by FrenchFrog. I think he used one on his tuned Lince. I think he had to do a little bit of fettling. But it's an interesting read. No pun intended. :D
