Carb Balance

[Jazzscot]

I made a DIY manometer like this one http://www.obairlann.net/reaper/motorcy ... meter.html today. I used 4 metres of 3mm plastic tubing and some electrical cable clips a length of wood and some red two stroke oil.

I put it all together and connected up the vac tubes and started the bike up.

The carbs wernt out by much but a bit if twiddling later both cylinders seem to be in sync. The total cost was £3.90 for the plastic tube as I had the rest lying around.

Went for a wee blast tonight and she feels much more responsive.

Cheers Jazz

That's interesting - similar principle to the ball bearing one I bought on Sirch's recommendation. Yet to use, but I can see how yours would work just as well, if a little less compactly

LOL thats the same as the one ive made mate, not had chance to use it to check yet though, but will Intentions were to get em done before ride up to opp storm on friday afty. might do em friday morn if the weather stays like this

Edit, my carbs aint been balanced since 2006 that i know of

Piss easy to make and it seems to be very accurate as well. Its not that Im a tight butt or anything honest. I just like to see if I can improvise.

mines made, take off points on the bike ready, just need 1/2 hour to connect up and balance away

i balanced mine and they both weighed the same

Ok some pics and a vid for you!!!!

Bike is connected up to the two plastic tubes. The liquid in the tubes is red 2 stroke oil (pic dont give a good view of the colour)






Bike is started and run till warm notice the levels are the same therefore equal vac from both carbs. I adusted the screw at the end of the video and you can see the fluid moving out of balance.
