Engine Stall

[Woogi]

Well, first, this site ROCKS! Wish I found it a year ago when I got my Blaster. I have a 92(ish)..(any way I can get the real year) Blaster 200. The oil pump is removed, and I have 2 stage reeds. That is about the only upgrades I have. Now to the issue

About 6 months ago, I started having preference issues, if I would wide open, it would shudder and I would have to Ease the throttle up, and issues like that. Then one day I was playing on it, and a reed broke. I assumed by running issues where caused by the reed going bad, so GREAT I had somthing to blame the issues on and I would just get a new set of reeds. so I got the Boyesen Power Reeds, new brake pads all the way around (because NOW that it was running right, I would need to be able to stop ;-) I even had the carb cleaned professionally.) After installing new reeds, the bike still wasn't running right, same issues. I then took the bike to the deer lease and it did ok, its quite ruff out there, so I wasn't doing a lot of wide open throttle. But then I was ridding it one night, I went to slow down, so I pulled the clutch in, the bike stalled. Would not restart, tried kicking for a bit, then the next morning tried push starting it, nothing. We came back home, I pulled the carb and 'RE-cleaned it' (was having an issue with the main jet clogging in the past) but when I had it cleaned my brother told me it looked fine. The bike has sat for a few months (I got a new Job and moved so I havnt had time) but a friend of mine is now going to look into for me.


Given this long story, and vague information, anyone got any ideas on where to start? ALSO when it was running there was a tapping noise coming from behind one of the side cases.

Again I really enjoy the site, cant wait for the bike to be running again, try some of the DIY mods on here.

u should check your piston and your crankshaft

also u should ditch the tors system its gay!

 

[Woogi]

Yeah, after reading about the TORS system here, I am thinking about removing it. Is there any reliable alternative? I don't want to die

You could remove the TORS and add a tether kill switch.

It is to my understanding, that just killing 'spark' will not kill a 2stroke that has a 'hotspot' in the cylinder. I thought that is why the TORS cuts the fuel and not the spark.

Am I misunderstood?

your problem sounds like a jetting issue. your main jet is probably too big or too small. only way to know for sure is to check the plug in that circuit.
the bike not starting is probably due to a blown piston. when you were trying to kick the bike over, did you notice anything funny or different in the kick?
pull the head and jug and check the piston out.

the TORS system is supposed to shut down the carb from delivering gas if the throttle get stuck wide open. however it does not work most of the time and decides to shut down your bike during normal use.

get the tors off anyway its practicly useless lol

Ok, well the issue was it had low compression, like 10lbs of tottal compression. So I had it board over and a 68mm piston put in. I took it out today, and I am having an issue with it revving up alot. If I am riding it and go to pull the clutch in (to shift or slow down) somtimes the motor will rev really high. But as soon as I put a load on the motor (release the clutch) it runs fine. My question is why is this happening, I dont be live it is the idle screw, because on 1st crank (even with the motor hot) it will idle for a bit but slow raise. (I dont typiclly see how high it will rise on idle because Ive been told idleing a 2stroke is a no no).

What is causeing my 'hotspots' or instant high idle when no load is on the motor?

(I am running pretty much a stock 94 blaster, with a 68mm piston, Boyesen 2 stage reed valves and ruffly 32:1 fuel)

Air leak??
