steptoe1111 Posted July 27, 2012 Posted July 27, 2012 hey guys how is everyone, how are you airhead been meaning to let you know how the dt175e went up against the yzf 250 well basicly i had him in the botom end but as soon as his bike started to advance and pull like a train he was a spec in the distance and i just endid up getting sprayed with dirt ha ha, but id rather be on the dt any day it gets a few more thumbs up from the oldies when you hammer it on a pass.. but just an off topic just made a home made manometer to balance the carbs on my kwaka dere i say it here on the yam forum but just thought i would post some pics and what i used i endid useing 10m of 5mm id clear hose cut into four sections(four carbs just block of two if only syncin twin carbs) all exactly the same length with elbows and t pieces at the base the theory behind it is it is filled with an oil generaly two stroke because it is easy to see in the tubes and you hook each tube up to the vecume manifold and from the readings of the hieght of the oil in each tube you can clearly work out if on cyl is pulling more air that the other there a many you tube vids of this design even of some in action i have not used mine yet but will soon i just need to install some mig welding tips into each airline to restrict the flow a touch otherwise it may suck up all the oil on that initial fire up but ill post the results from what i have read these are ment to be way more acurate than the vac dial gauges wich would set you back atleast a $100 and they would be the cheap ones too "acuracy and cheep dont often go together" here are my pics any way ... there are alot of people out there that have made these already and thats where i got my plans from but i just thought it was such a cheap and reliable tool to make that i went ahead with it and if someone comes scross my post and learns what i did from my imformation id be thrilled ... but is a must have tool for any d.i.y,er out there with more than one carburetta
Moderator drewpy Posted July 27, 2012 Moderator Posted July 27, 2012 I just use me vacuum gauges I got off a carboot sale, and they are a lot smaller than that arcade machine props to you but there are more elegant solutions out there too,
kevinneill889 Posted July 27, 2012 Posted July 27, 2012 I also made my own but a much smaller version and works a treat. I will say that you do need to restrict the flow as i never at first and it sucked near all the oil out the tubes once i fitted the restictors though was fixed and working proper mint.
KirriePete Posted July 27, 2012 Posted July 27, 2012 I've been using my 2 pot differential manometer for a while now and it's proved way more accurate than any other setup. Whereas yours works by each pot sucking against air pressure or a closed pipe, the differential setup has the carbs sucking against each other so no danger of the fluid being sucked out, plus there's an element of self-damping built in. Here, have a video: For a 4-pot system (eg the lad's Bandit 600) I balance 1&2 then 3&4 then 2&3, you generally find they're linked in pairs like that anyway, so no great problems. I'd be interested to see your setup in action, gonna do a vid for us?
