View Full Version : Reed Valve and Boost Bottle

16-05-2015, 05:26 PM
I'm currently working on CAG project just for a bit of fun and I want to see what kind of speeds I can get out of it. I've heard loads of different things, but just wanted to get some advice because I'm a beginner. I have bought a boost bottle kit, but when I went to install it, the existing carb manifold had a reed valve on it. In order to install the boost bottle would I have to remove the reed valve - or can I have the reed valve and the boost bottle at the same time? Plus, how would changing this all affect the performance?

Cheers for the help in advanced.

Hi, what ever you do you need the reed valve. It will not run without it!

Okay - do you think it would be any good installing the boost bottle too?

No. Its a crappy strimmer engine, it will always be low performance unless you change all of it will cost more than a real engine. Sorry to be blunt but thats the way it is and we've all had this convo many times before. If you have a CAG your best bet is to try and get it reliable and just ride it...... on a track.

To be honest I just want to have a bit of fun building it up. I've swapped out most of the engine with new parts: High performance cylinder head, high performance plug, high flow air filter and 15mm carburettor, balanced crank, ported piston windows, upgraded clutch and bell housing with pinion support.

listen to jibberwobble, (iv been there and done it) it doesn't matter what you do to a cag engine it will still have poor performance (putting on some of the mods actually made mine slower and have worse reliability) and in the end was a waste of money, I would just ride it till it breaks and then get a proper bike.
