I went for a razz down the coast the other day , stopped the bike for 10 mins. It started first kick but stopped whist I was pushing it off the centre stand . I then gave it half a dozen kicks to no avail , I used the hot start button and boy did it let me have it . Tears welled in my eyes , my ankle ended up twice size , I couldn't gather courage so I set the posi and pushed the beast. Question ? Would running B.P.Ultimate cause the bike to do such a dastardly trick ? or has anyone ever fitted lecki start to one of these machines ? My recupperation time increases by years of time .

Hi Dave, Ooops, sorry to hear about your pain...actually I have never been kicked back by an SR in over 27 years of ownership. This is a fairly rare occurrence. The SR's have a mechanism that disconnects the kickstart lever from the engine at full kick stroke. This is a useful thing to know, and so long as you always kick right through this won't happen again. Just keep it down. Having said that they usually only have the opportunity if you are tentative with the kickstart (...something I personally haven't seen), or the timing is out. If the bike runs normally once started then I'd say that the timing is fine. Always pays, in my mind, to use the de-compressor as part of the starting ritual. Put it on compression then use the de-comp lever to take it a few inches past or so, then release the lever and the kickstart back to top again. Then give the SR a nice firm but steady kick right through to the bottom and usually away they go. Don't use the throttle until it starts to go. When they're hot it can be a little problematic sometimes, however you develop a knack and all is OK. I have been 'brutalised' (heh, heh) by a TT500...that bike was mistimed...yes pain is then the order. That one had a badly scored crank end and kepy shearing the woodruff key and the timing would slip...had a 360 Yam that did the same thing...aargh. Hope I have assisted you in some way. As far as I'm aware there are no dedicated electric start kits available for the SR. SR  |

Hmmm...that came out the wrong way...I was indicating that I personally hadn't seen an SR with an 'out of timing' that occurred during normal operation...others may have. I certainly have seen plenty of people have trouble starting the beasties of course...just takes a short while to develop the particular knack for your machine. Usually the procedure I mentioned works fine. Don't give up. SR  |

Hi guys,
I have had similar experience to you, Stew, in regards to starting SR/XT/TT's, I rode my first XT in 1976 (30 years ago, I must be getting old!) and the only time I have had problems getting them started was if there was some type of problem. I will admit that I I roll start my SR every morning, my driveway has a gentle slop, and it is just "SO" easy to roll out of the shed and bump start down the driveway than to kickstart.
I have done in a knee starting my SR once. I had stopped to refuel, and when I started the engine, with a normal strong deliberate kick, it fired and ran from almost the moment that the kickstarter moved. Hence I was effectivly kick starting an engine that was running. The kickstarter moved straight to the bottom of its stroke with no resistance and my knee almost bent backwards. The mates thought it was the funniset think that they had seen, while I limped around the fourcourt complaint about a bike that started!

I have been pondering electric starts for a while. I have never had a boot from my SR, though the XT (points ignition) is a different beast.
Anyway, in theory at least, there is a way to make the SR alternator function as a motor. I'm working on it.
If I get it to work, can I count on a few sales?

Hi again,
I have been in the electrical/electronic trades for the past 32 years and the answer to making the SR alternator work as a starter motor is NO! The SR alternator is a 3 phase permenant magnet altenator and will not work as a DC motor.
If anyone remembers, some of the Yamaha road and trail bikes of the early 70's were fitted with "dynastarter" which were a combined DC generator / motor. These bere bulky, heavy and not the most reliable things, but I supose they did the job.

Correct. A three phase permanent magnet alternator will not work as a DC motor. Mick |

Thanks for the advice guys . I think its got a lot to do with the hot start button as it doesn't give me any grief until I use it I see a few different places that the pump rod can be set this is possibly incorrectly set . No comments on the higher octane fuel ? I owned my 1st SR500 in 1979 , it was always a good starter hot or cold the only probleb I ever encountered was the CDI pickup coil going open circuit on the alternator . I had to rewind it and it went like a beauty !

BP Ultimate is the 98 Octane stuff? that's the one I reckon is the best pump fuel I've had so far.
Have had another thought about electric starts. There are some very small pancake style motors around. These are about 6 inch diameter, with a body 2 inches thick and about 1/4 HP. 186 holden car starters were 1/4 hp.
I reckon it would not be all that hard to make up a ratchet drive set up with a left hand thread to screw into the end of the flywheel, then use one of these motors to drive the flywheel via a hole through the alternator cover. You'd have the cranck shaft and starter shaft in a line, if you see what I mean. A motor about 2 1/2 inches wider would not be a problem.
Expensive though. I looked one up in the catalogues at work and I reckon the motor alone was over $600.
Long way from there to a working kit. You'd have to make up either a whole new cover or some decent looking cap to cover the motor. Plus ratchet drive set up, wiring, solenoid, starter button, etc.
Still reckon it can be done though. Funny thing is, I don't personally want one, I just reckon it'd be a great challenge to make it work.

Hi its Dave again , ankle is still sore (sprained actually) ! Lucky for me I,ve got a nice little Laverda 668 as a spare bike (its got one of those girly/man electric starters) so I can still have fun whilst I ponder the problem . Cheers anyway chaps .Good safe riding for 2007!

Hi its Dave again again . Ankle is good & I got back on the horse yesterday . 1 good kick (with my good ankle supporting work boots) did the trick to restore the confidence . As it barked into life I made a rush for the helmet & went for a quick spin . Oh yeah nothin like the grunt factor of a 5ton1 ?

I've noticed a good solid set of boots really does help. Oh and i use BP Ultimate too. I used to use it in my Alfetta before she died  |

Yeah I put BP ultimate into every thing - bike,boat,mowers(makes a good 2 stroke mix) . My SR & Laverda just lust for it . Must burn real clean as I don't seem to ever need spark plugs ? I just thought it may have been responsible for the SR firing early when I kick it ? I've only got back on an SR after a very long absence . I owned one from 79 to about 82 , don,t no why I sold it but I'll blame my mother . I used to run it on super(leaded) . Did any one else ?

I run the BP ultimate and think is great. MY bike shop guy mostly works on European bikes and older ones at that, and he had some customers mentioning that the premium stuff can cause some fouling of plugs (referring more specifically to my bmw r65LS). I haven't found this to be the case. Anyone had this issue? As for a sturdy pair of boots...well I usually wear my Johnny Rebs, which are good (harness/engineer boots), but the other day I tried my Redback work boots. These things have and "air -comfort sole". I hardly felt the kicker in the arch of my foot at all. I can't reccomend them enough. They past the biggest test - I pulled them out of the box 5 years ago, no break in, then off to the US Mid-West on a meat tour where I was on my feet 16 hours a day for 16 days, 12 of which were in a frezzing abatoir. Never got aching feet once, not at all. www.redbackboots.com/upbfsd.html |
