G'day to all ! & trust you are all havin a great weekend with the great weather we have at moment ! My trouble's are this , I bought my 88 mc19 & the bike had an aftermarket pump already on it, no good, too much pressure creating a leak at back of carb's. Next, my brother in law bought x2 off ebay, which were thought to be for honda replacement, way too much pressure, still leak's ! I know it's not just my carb's cos I bench tested the pump on spare set of good carb's, same prob ! I know you can get a pump from Repco for these but I need to now what I'm lookin for as to pressure I need and so on ? Has anyone else had this prob or know anything about my problem, NEED HELP ! Thank's !! Matt
Hey Matt know what your experiencing with the after-market pump. Had a similar issue with a Suzuki Across, drove me up the wall until I obtained another Across pump and the problem vanished. Having said that, I've heard that a regulator can be utilized to meter the fuel flow to the carbs. It connects to the fuel line coming from your pump and can be regulated manually to deliver the fuel at the precise volume required. Wish I could tell where to find one, perhaps somebody on the forum can point you in the correct direction. You could also search for an original pump on findapart, would be the simplest way I think. Best of luck mate.
Thank's Phil & Cal !! Was thinking maybe a regulator might work ! these pump's that i have now definitely have too much pressure. Might make a trip to Repco, see what I can find. Anyway's thank's for the help, it is much appreciated.
Welcome. Buy a proper pump or a regulator, not one of those shinny things with nob on top that are really restrictors (you do the same job with a tap). Another (cheaper) alternative is to use a return line from a 'tee' piece in the pressure line to return the excess fuel back to the tank.
Cheers for the info Murdo, Will have to go hunting to see if I can find a regulator, more chance of finding one than the correct fuel pump ! Thank's again Murdo.
This a proper regulator, identifiable by the adjustment nut on top. Have used these and they are adjustable and work as a proper regulator. http://www.ebay.com/itm/Weber-Redli...pt=Race_Car_Parts&hash=item4171bdc7d3&vxp=mtr
This pump could be useful. http://www.ebay.com.au/itm/NEW-12V-...sel-Petrol-Low-Pressure-HEP-02A-/301408555675 And this regulator. http://www.ebay.com.au/itm/QUICKFUEL-FUEL-LOW-PRESSURE-REGULATOR-1-4PSI-Q30-804-/171451596930
Thanks murdo, goin to have a look this arvo !! Another question is has anyone tried to run an mc19 on gravity feed like the mc22 ?
Yeah, i thought of that too ! But on the flip side i thought maybe being as smart as the designers of these bikes are, maybe when they went to the mc22 they figured the carbs on 250's didnt need a pump, & decided to take it off ! Was just curious to know if anyone has run a mc19 without pump ? have heard people say "oh, my mc19 doesnt have a pump, and runs fine "
The MC19 can run via gravity feed. We got our MC19 without a fuel pump installed and it was running. I don't know how long it runs until it runs out of gravity pressure to feed the carb though. We then sourced a fuel filter & bought this pump from eBay and it's been working great for over 6 months.
