Got all the bits don but for some reason i have no spark naw so frustrateing i was just about to go for a test ride but no spark to either plug naw has anybody else had drop outs like this think it may be the dyode

[azwood80]

Ok got spark again but its poor even with new plugs cant work out whats going on eneyway i fired it up and it onley ran on the back cilender front pipe was cold i kept it going for a short time hopeing the front cilender would cum back online but nuthing i was thinking of checking the gap on the pulcer coils outherwise i dont no what else to do the joys of old bikes hey......

[JonW]

sounds like a bad earth somewhere along the line, worth checking and cleaning them up before thinking its more serious perhaps?

[azwood80]

I agree if it had good spark and naw its just crap all the sudden it was starting with 3/4 kicks till naw.one thing that has me confused is why is there wires to the battery reg from the cdi,s why would they need power to work?? If thay do if my battery is a little flat that would probly caurse isues

[azwood80]

I think ive had enough of this chaseing spark isues i will just take it all out and send it to small coil rewinds they will get it sorted.

Got it going dont no what changed but it runs on both cilenders naw so i went for a little spin first impression was i need to shorten the gearing but its not bad power wise it pulls hard and clean even thow it needs a rebuild it goes well on the pipe realy looking forward to getting it all rebuilt to see haw it goes then.

[azwood80]

Thanks tzr250 for the link my phone wont do it.the thin wall pipes make a nice crisp sound i might build some stainless steel ones one day.

Went for anouther little ride this time i went threw the gears and a funny thing happend all the gears were backwards so first is up the reast are down after thinking wtf i realised on the kr,s the shifter goes on backwards so i can either live with it or make a linkage to corect it what do you guys think it would be funny if sombody else rode it and i dident tell them . One good thing is the gearing seems pretty good naw im not takeing off in secound
