Hi guys,two day old new owner of a 83 SR Japanese import,love the bike but its a cow to start on the kicker,no worries pushing and jump starting,just the embarresment of it all,havent checked compression yet but all else seems fine,maybe running rich,ie blackish plug, visible black smoke when reving at idle.It has a K&N filter.I take it the light coloured/shiny bit in the window is TDC??and then you kick hard with no throttle,only choke when cold.Tips appreciated cheers dandog

Sounds like a peek at your mainjet/needle may be worthwhile to find out what's in there. Is the plug type correct for stock? A new plug is of course SOP with any bike.
I have to hold a little throttle on if mine gets flooded, perhaps yours is running rich enough that opening the throttle a bit would help. Don't twist it around tho... open slow and hold it there - don't want the accel pump giving you even more gas.

When I kick my bike I give it more of a throw with my foot instead of following all the way through. My 81 likes to start when the TDC is just about to show in the window, while my 78 likes to start with the TDC mark a click past the window. I talked to a local guy who was selling his and he seemed to have a pattern set, but he said a few years ago after a complete overhaul, it took him two weeks to figure out the new pattern.
Both of my bikes are pretty testy. The 78 is one that gets ridden, and I had a helluva time trying to figure it out.
If the suns out- its one kick no choke.
If its cold out or night- Then 2 or 3 slow kicks on the lever to pass TDC a few times, or hold the decomp and give 5-10 swift kicks. Then a fast kick and no choke will start it right up.
or
Full throttle, choked, and a hard kick. When I start like this the bike vibes itself back to the curb when on the centerstand, and I usually scare the crap out of everyone within 15 feet.
Have you looked at the carb to see if its clean?

My kickstart indicator doesn't work so I roll it back in first gear till it stops, so I"m near TDC, then just roll off it forward enough to get back into neutral. then dependant on how long its been sitting:
full choke and a swift kick
or no choke and one kick if its warm.
No throttle in either case.
Took me a week or two to sort out its sweet spot, but I couldn't even get mine roll started at first flying down the biggest hill we have......

This forum is good like that Dandog.
I was doing a lot of things 90% right, but asking around here found that the 10% made a world of difference, and every time I was mental and thinking of offloading my old girl (bike not missus) I get more reasons to keep it........
Good to see you're firing...

Hi All
My method is : just over compression and half the travel on the kickstart, bring back to the top and give it a kick
This method starts it first time , my problem is I don't use choke and the engine runs and pulls without choke on a cold morning. When it's warm it's hard to start , takes about 5 hard kicks , There is a trace of soot in the exhaust pipe, I have cleaned the carbi and checked the level, whats the next step ? drop the needle a notch or look at idle jet, no number on main jet
Thanks in advance for any help
Barry

When you say the light coloured shiney thing in the window is the TDC what are you talking about? I have owned my 79 SR for less then a week and it is an absolute pregnant dog to start. I am sure it is a technique thing though. Some mornings I go out there, put the choke and give it a kick and she starts up fine...most case though I end up running up and down the street trying to roll start the *&^ing thing.
What is the TDC and where do I find it? Sorry if I sound like an absolute novice but in this case I am....anybody know if you can get an electric start for these babies...hehehehe
My right ankle is bruised beyond belief.
Also noticed that when it does get started after I have been trying for a while that it blows a bit of white smoke until it gets warmed up. Not sure whether it happens when it starts first kick or not. I mean it has only happened once.. I was so surpirised that I didnt even think to look for the puff of smoke.
The bike has apparently just been serviced and has a new plug....
It is stock standard currently. Still has the original pipe and the airbox hasnt come off yet.

It hasn't been mentioned in any of the replies, have you used the "Hot Start" button on the left side of the carb?

I really have not had any trouble getting my SR to start (other than when the stator died). My time with a TT500 30 years ago helped though. I don't bother with the indicator window, I just find TDC when the compression makes it hard to turn, pull in the decompression lever to get past that, and give the kick starter a mighty whack.
No throttle at any time, full choke when cold, and about half choke when warm. I don't bother with the hot start button as I find that the half choke when hot works better. As I understand it the "choke" is actually an enrichment circuit so using it when hot just adds a bit more fuel, as opposed to a real choke which enriches the mixture by reducing the air,
My SR usually starts on one kick, hot or cold.
The thing about the throttle is that the stock Mikuni card has an accelerator pump and if you use throttle you'll flood the thing and then it will be very hard to start. That's what the hot start button really does, add a tiny bit of throttle without activating the accelerator pump. Try it when at idle and see, same with the choke.
