Guest Posted February 19, 2008 Share Posted February 19, 2008 Tuther day when I took my Zeph out for a weeee blast in the (then) glorious sunshine, I noticed that at around 7000 rpm I was pulling as cleanly as what one ought to be doing ...It was a bit like hitting a rev limiter ....My hunch is that my carbs are way out synch ...With this in mind, I'll need to balance them.I've a rough idea of how to do it and what I'll need to rig up - make shift tank, and buy gauages etc ...Is there anything else I should be aware of? I know I'll need to find the adjusters before the engines hot or I'll burn my pinkies looking for them ...Is it fairly easy peasy?? Quote Link to comment Share on other sites More sharing options...

Stu Posted February 19, 2008 Share Posted February 19, 2008 nah balancing really only affects the low rev range of a bike to be honest how does it idle ? is the rev counter needle nice and steady or up and down ?might be shite in the carbs Quote Link to comment Share on other sites More sharing options...

Guest akey Posted February 19, 2008 Share Posted February 19, 2008 First thing to do is check you have fresh fuel as it will go off over time, then i would suggest getting some wynns carb cleaner and giving the carbs a blast with that before you go down the balance route.Simple first.

Guest Posted February 19, 2008 Share Posted February 19, 2008 nah balancing really only affects the low rev range of a bike to be honest how does it idle ? is the rev counter needle nice and steady or up and down ?might be poo in the carbs Mmmmmm!They might need a strip and clean ... They've probably not been done since the 18th century The tacho needle is steady in use, or at tick-over and through warming up, but the bike doesn't rev as cleanly as it should ... For instance, if I hold the throttle open so the needle would go round to the redline, it sometimes jutters around the 6 - 7000 mark - so it might be muck...I want to stick a decent air filter on too - the factory one is a right big ol' gay plastic thingy Quote Link to comment Share on other sites More sharing options...
Stu Posted February 19, 2008 Share Posted February 19, 2008 you got a after market pipe on ? and when was the last time you changed the air filter ?oh also look for the exhaust blowing anywhere Quote Link to comment Share on other sites More sharing options...
Guest Posted February 19, 2008 Share Posted February 19, 2008 you got a after market pipe on ? and when was the last time you changed the air filter ?oh also look for the exhaust blowing anywhere Pipe fit is quite good ... will check it more closely though .........It's a Remus stainless - the original would have rotted away hundreds of years ago ...................I changed the filter last year - at the same time as doing a full service - oil plugs and both filters so that should be v clean still ..

Guest akey Posted February 19, 2008 Share Posted February 19, 2008 Im with stu here I did the wynns stuff and a new pipercross air filter on mine tonight, have used wynns before and a new air filter always makes a bit of difference.when you use wynns you need to keep the revs high though to stop the engine stalling and watch the nice blue flames out the exhaust as you throttle off or blip the throttle the first few times after its been sprayed Quote Link to comment Share on other sites More sharing options...

Stu Posted February 19, 2008 Share Posted February 19, 2008 it might be worth looking around too to see if there is a local place that can do you a dyno run and tell you what really is happening well worth the 20 - 30 quid they chatge just for the run a full set up can cost upto £200 though but that is money well spent if you are keeping the bike Quote Link to comment Share on other sites More sharing options...

Will have to see how things turn out ... need to sell my Merc too .. that'd help ... Quote Link to comment Share on other sites More sharing options...
Stu Posted February 19, 2008 Share Posted February 19, 2008 nah dyno runs are for every bike they check how it is fuelling across the full rev range and can adjust all the needles and jets to suit for a strip clean and balance i would say no more then about £120 but if you get the carbs stripped cleaned balanced and set up on a dyno it will be a lot cheaper and also a lot cheaper if you do the cleaning and balance yourself shame your not closer i have a set of guges you could have borowed Quote Link to comment Share on other sites More sharing options...
Guest Posted February 19, 2008 Share Posted February 19, 2008 Ummm ............I'd pretty much persuaded myself to do the balance myself ...Don't know if I like the idea of doing the strip and clean though ...aren't there fifty billion teeny bits in carbs ??I'd probably have half of them left over when I'd finished Quote Link to comment Share on other sites More sharing options...

Guest Posted February 21, 2008 Share Posted February 21, 2008 I've had a word with the bloke that has part of the DPS building in Keefley - very knowledgeable sort too!He reckons there's no point putting it on a rolling road at this stage, as it's very likely to be the carbs ...I asked for some prices too ...Rollie Road - £25.00Carbs strip - £120Valve clearances - £75 (+ however many shims need replacing at £4 each)So its looking like the carbs need a reet good seeing to rather than just a balance ...Stands to reason really ... bikes probably not had them done for ages!Now just need to decide which bits I'm going to do myself ...
