SRXy Posted February 11, 2005 Share Posted February 11, 2005 oops...Topic should be leaded or unleaded I live in South Africa and we are facing new laws which prohibit the sale of leaded petrol. I'm wondering what effect this will have on my bike. I'm recently purchased a SRX400, and can't seem to find out if it uses leaded or unleaded petrol..... What would happen if I used unleaded petrol in a bike that used leaded petrol and vice versa? Any help would be greatly appreciated!!! Link to comment Share on other sites More sharing options...
Admin Alex Posted February 12, 2005 Admin Share Posted February 12, 2005 Im not sure what your bike is supposed to run on, it may be able to use both anyway. Basically your bike will still run on unleaded but will wear out the valves, and may burn your rings as the engine gets hotter. I wouldnt worry about it though, as the garages will all sell fuel additives which you will be able to add to regular Unleaded fuel which has a lead alternative in it Link to comment Share on other sites More sharing options...
yamguru Posted February 12, 2005 Share Posted February 12, 2005 every yam since 1982 has been designed to run on unleaded with many able to do this well before that point there are some exceptions but unless you have a race bike or a DT50MX i wouldnt worry about it Link to comment Share on other sites More sharing options...
Moderator YamaHead Posted February 12, 2005 Moderator Share Posted February 12, 2005 I believe Yamguru is right..... They all have hardened valve seats now.....enabling the use of Unleaded fuels. No Worries. Link to comment Share on other sites More sharing options...
yamguru Posted February 13, 2005 Share Posted February 13, 2005 the Japanese were gearing up for unleaded as far back as 73 so most bikes from that point can run the fuel there are a few exceptions but theses are mainly sports bikes RC30, CB1100R and that speed demon the DT50MX!!!! if you have any doubts i have all the records and spec on file Link to comment Share on other sites More sharing options...
skyline Posted February 13, 2005 Share Posted February 13, 2005 i used to have a dt50mx, managed to blow the piston and barrel every couple of weeks did not like that bike at all...but then i never ran it on leaded.... Link to comment Share on other sites More sharing options...
SRXy Posted February 14, 2005 Author Share Posted February 14, 2005 Thanks a lot everybody......My bike's a '92 model so it seems as if it wil be ok. I'll post some pics as soon as it's back from it's service. Had to give the carb a good clean out, put in a fuel filter, put new tires on and new fork seals. The bike seems to have been standing for a while......I think the previous owner went onto something more substantial. Anyway..I keep in touch.

chrisw Posted February 14, 2005 Share Posted February 14, 2005 Could be an issue with the Octane Rating though Leaded Fuel was 98 Octane Rating Unleaded is 95 Octane Rating. I know you can buy Super Unleaded but that was actually more harmfull than leaded fuel because of the Benzine that was added, that may have been changed now though. The thing is the Petrol Companies and SA Government will know of the issue's and a replacement will be available in one form or another. Link to comment Share on other sites More sharing options...
SRXy Posted February 15, 2005 Author Share Posted February 15, 2005 I would hope so!!!! I'm not betting on it though. The real problem is that most of the cars is SA use leaded petrol, particularly the taxi's which serve as transport for ~60% of the population who can't afford a car or a bike. So I guess this will force them to find a solution. Link to comment Share on other sites More sharing options...
