I think my ignition has already been worked. It doesn't look anything like the pictures in the Haynes manual.Originally Posted by F5 Dave
What type of ignition is it? CDI?

no I think it's little miniature elves with switches a can of electricity that all live in a small black box. I think your one was RM so should be fine.
I bought the KX one but wasn't as well suited to the 50 as what I had, but you don't know unless you try.

Done. Now where was I? Oh, yes...

What kind is it? I have seen two basic types, one has a completely round base plate and an external trigger coil on the side and the other has a roughly triangular base plate. The triangular one can be made to fit GP125's easily and I imagine other Suzuki's. The round one's external trigger coil fouls the case making it more difficult but not impossible to use.
What kind do you have?

I must dig it out, I fit it to my RG50 fairly easily, just it didn't work as well on the 50 as my other one so I never used it. I'll drag it out when I have a mo.

Yeah mine is the round one, I'd made up a plate that bolted on the std RG mounts that I would have thought was same as other suzukis & that put the trigger in the space area at 2 O'clock. Then I re-slotted the woodruff key in the flywheel so timing was in right area to adjust.

Hi F5, does the stator have an external trigger coil? Do you have the complete ignition system, stator, flywheel, black box and coil? How many $$$$ ?

I just realised something after reading the past few comments, I know jack shit about tuning 2 strokes! I don't want to push things too far, as my budget is very limited, so Bang is bad... The 100 is staying just that, a 100. I reckon its a pretty decent engine, had heaps more grunt than my old ax100, with a sloppy shit piston too! I reckon Ill just grind a mm of the top of the exhaust port for now and maybe shave a little off the head to increase compression and get a new piston... That should give it a new lease of life, and then from there I can play with the rotary valve and carby. Besides, no use having something fastish without having much racing experience and with a chinese plastic front tyre.
Tyres down.. Porting, chamber, piston, carb, experience riding, etc still to go!

i have found a good stock gp125 to be realy good up here at Mt Wellington
nice tight slow track under 100k/h
much better drive out of the corners than some of the tuned bikes
helps me as I'm no valintino
if i could ride better a faster bike may be an advantage but the pull out of corners when i muck up makes up for that

If you have a shitty old piston in it now I may (just from what I have read - I am no expert) be a good idea to file from the top of the piston rather than the exhaust port, that will give you a reasonable idea of how changin the port timing will affect the characteristics of the motor.
barrels = expesive.
pistons = cheaper.
and you were going to replace it anyway right?!
you can file a bit off the top in line with the exhaust port and do a little at a time and test to see the effect then if it works ok you may even want to just file the new piston to the same point as the old one and leave it at that.
as for the 2 stroke tuning: read good books!
I just read one by A. Graham Bell and it is farken mint, try get ur hands on some good tech books on the subject and you should be able to build a real fire breather

ok, this'll all have to wait for a bit, I just crashed the gp100 doing 80ish kph. Back tyre burst/rapidly deflated in the wet!, and hit the deck... I reckon I was pretty lucky though, just scrapes and bruises!

scrapes on the GP and bruises on you?

I have that book saved on my computer (Graham Bell one) as PDF... If anyone wants a copy, shout! Though some of it is still a bit too advanced for me, even though its pretty straightforward. Also have a computer expansion chamber designer, where you plug in a whole lot of numbers and it decides an optimum chamber for you bike. Generally speaking do they work??
Yeah, I was pretty sore afterwards, thank god for nurofen though! Was lucky as if it had happened a 100 further down the road, I would have been on a steep downhill with barriers on each side towards the bottom. Would have been f***ed up! Scrapes on the GP, and no skin on me where my jacket rode up my arm! Mind you, nothing compared to some of the stories I could read about no doubt!!

I'll let you know. Mines 80% built to that program. I used the program then cross checked it with Bell's book. Very similar specs (within my building tolerances anyway).
