My bike has a pretty easy life. Just thumping to work and back. I want to know if i could safely try a slightly hotter plug as the standaed BP7ES always looks pretty black when i take it out. The motor is fresh and despite the plug looking a bit dirty the bike runs beautifuly. What do you think? I know that a plug that is too hot can do damage, but maybe one degree hotter might help keep the plug cleaner. Or maybe i am just being pedantic.

Hi, No your reasoning sounds pretty right to me, but having said that I would not go hotter than a 7 myself...just an unnatural fear of melting pistons...especially in the Summer. Being an ex-MX'er I usually go one grade colder if I'm revving it a bit...but over the years I have chosen to go back to a 7 for the reasons you talk about...riding to work I would occasionally carbon-up an 8... Problem is, in my thinking, what would happen if you ride quickly out in the countryside with the 6 in on a hot day rather than go home first and change it??? Anyone ever used a 6 in the heat???

Yeah, i think your right. Its not as if the plug is fowling. STOP PRESS. Today i finaly got the start down pat. It took me two weeks to realise that giving the throttle a twist during the kicking motion doesnt help. Just let the "choke" do it. Iv,e only ever had dirt bikes, and that was twenty years ago. A couple of bultacos and a maico. My mates called it the "maico breako" coz it spent most of its life under a spanner. Anyway about a month ago i spotted this SR in a local shop. It was love at first sight. Took me a couple of weeks to trick myself into thinking i could afford it. But anyway, we live together now.

Good call Stu , back in the old days (leaded fuel) plugs used to come out all different shades & diagnostics was a sweet thing . you could tell easily lean , rich , hot ,cold etc now I don't see a lot of discrepancies . I mean if the bikes running OK I just replace the plug when needed (it usually pays to have a spare & spanner stashed in the tool holder) . I think that if the carby is set up OK the electronic (CDI) ignition is good & sparking in the right place the only thing left is the right fuel( BP Utimate). And wammo the equasion is complete . Cheers chaps , Dave .

Hi, Yep, usually don't touch the throttle during starting until you get it fire anyway...with the accelerator pump you can flood it quite nicely. If you do flood it you can pull in the de-compressor and open the throttle fully and keep kicking it through with the lever held in until you hear it fire in the pipe then try again...or leave it and walk away for a short time...works wonders and possibly saves you a heart attack...heh, heh...

Anyone ever used a 6 in the heat??? To revive an old thread, I was kicking and kicking yesterday, running late for work (I'm a Uni tutor, so that's bad - a class of assessment-anxious students waiting and leaving), and when I checked the plug it was fouled (don't know if that was the root cause or an effect of the original cause of the non-starting, which then compounded things). Put a new plug in and she started first kick, but what I noticed was that I was running a 6 - have been all summer! Now I remember that Spring last year the mechanic who did top end work couldn't get it started and so put in a hotter plug, which I took out, then replaced when I was stuck one day, and forgot about. So I've run it all summer and the bike seems happy - not that I'd know what's going on in secret places where this matters. But she has idled more happily than ever, whereas she used to stall a lot, and starting has become a cinch. Could this be due to the hotter plug? |
