Tommy xs

there's still a few about considering they weren't very popular. the only problem iv'e had apart from normal w/t was when she was only 18 months old, both the exhaust holed big time and because it was a new model at the time no one was making after market parts for it Yamaha was wanting £180 for their replacements (bike only cost £1284.00 new) I wasn't going to pay that kind of money for another 18 months so i stripped her down and put her in boxes under the stairs and their she stayed till i moved house 8 years ago, then with wonder of the interweb i found what i needed including another whole bike and my brother bought 1 to do up and got fed up with it so now i have 3. the Maxim as drewpy referred to is much rarer as i don't think it was released here but iv'e seen a few imports i never really liked the look of the maxim supposed to be the follow on to xs us custom but to me was plain ugley but to each their. I see you like the old two strokes do you still use them much ?

only just seen this thread all i need is a hammer cos if i can't fix it I can wack it

No don't think so rd250lc much chunkier, you'd be better looking at similar size bikes i.e 125 of around the same age

a lot of people say its a XJ motor cut in half. cos the XJ is a four not a twin but your right it was the last of the aircooled twins I believe it was introduced for the american market because the RD350LC was banned because of omissions noise mainly it was called the Seca 400 in the states ,it never became popular here because of the LC but i bought one after just passing my test on a XS250, seemed like the next step up at the time and i still have her today still going strong

i only became aware of this problem recently when i asked about unleaded fuel in my old bike and the more you look in to it the worse it gets, its good that more people are now getting informed about this problem and by discussing it you have probably saved a few bikers a lot of hassle and money. hope your thread gets lots of views the more people who see it the better thanks to everyone who answered my questions when i needed help

don't claim to know what i'm talking about but wouldn't the Digitally re programmable CDI take care of the carberation and the fact that no one else is doing it makes it all worthwhile, to have the fastest XT125. (even if not by much) I get it, just wish i could afford it. or had the know how best of luck oh and if 25cc is not lot, well you'll only have 25cc less than a 175cc and with all the other performance parts you should have no trouble keeping up let us know how it goes

live & let live that's what I say, I just smile and say "I know yeah" and leave them with a confused look on their faces co's no matter what you say they won't understand and sometimes ignorance is bliss.

thanks everyone, put my mind at ease first time i run on unleaded.

its great to be back on a bike again, I feel its like a time machine, get out on the back roads you'l feel 21 again nothing else like it, enjoy the summer

Thanks for the advice been busy google ing and you do have a good point about the ethanol, i didn't realize it will cause so much damage to carb seals etc, also the year is fine with unleaded. the money iv'e wasted on redex over the last year could have had a good few more run outs with that, i will still put a bit in now and again just to cushion the valves cos the bike is running fine 31 years old must be doing something right ? thanks again I will take your advice and look up ethanol free fuel cheers

when i bought my xs400 in 1982 I ran it on 4 star petrol or even 2 star if money was low. since I put her back on the road last year iv'e been using lead replacement additive by redex but finding it harder to find lately iv'e seen something on ebay that looks like three lead weights in some chicken wire, that you just drop in the tank, has anyone else used one and do they work. still got to refurb tank so meantime still using redex. but would appreciate any info thanks..

no guru but you need help i,ll be there ""locally"" 2 heads are better the 1 and no i only have 1 head

that has to be best xs i've ever seen FANTSTIC slightly moddod ha ha

thanks very much for that i'll give it a go next weekend and let you know how i get on
