bashplate Posted June 2, 2014 Report Share Posted June 2, 2014 Hi folks, went out practicing on the TLR200 on saturday, bike starting and running spot on. Then after about 1 1/2 hours I stopped to have a drink, went to restart....and....no go. this was due to the de-compressor being stuck open, so no compression. When I removed the decomp cable, the arm in the head returned to normal position and compression restored the bike started first kick. thought I'd better investigate and removed the clutch cover to see what the problem was.....found nothing obvious other than a wee chip/wear on the corner of the cam on the kicker shaft which operates the decomp. Cable was also free, so put it all back together and all is good. SO, any ideas, I'm hoping it was a fluke and won't manifest itself again in a trial!!!!!.

windwelder Posted June 7, 2014 Report Share Posted June 7, 2014 Hi I had much the same thing, I tracked it down to the bolt that stops the shaft in the head coming out, having no copper washer under it . When it was cold it was fine when it got warm it would hold tighten up on the shaft causing it to grab the shaft just enough to stop it rotating .

sicco Posted July 15, 2014 Report Share Posted July 15, 2014 Hi, I had the same, but in my case it was a little rock/dirt that sat between the cam follower arm and the frame. At first it was difficult to see because the whole bike was dirty. Quote Link to comment Share on other sites More sharing options...
bashplate Posted July 16, 2014 Author Report Share Posted July 16, 2014 Thanks Sicco, another proberble cause!!!! I've had quite a few practice rides since putting it back together, just to make sure it doesn't manifest again in the middle of a trial.....and so far all is good.

fp90lawrence Posted September 17, 2014 Report Share Posted September 17, 2014 My cable was too close to the exhaust. Cable rusted right where the exaust pipe was...plus never lubed. Quote Link to comment Share on other sites More sharing options...
bashplate Posted September 18, 2014 Author Report Share Posted September 18, 2014 yes the cable does run very close to the header pipe, mine had burnt through the plastic outer cover...so i cleaned it up and put some heavy duty heat shrink over the damaged area and slightly rerouted the cable to stop it happening again.

Rollox Posted September 18, 2014 Report Share Posted September 18, 2014 I use a cable guide from the fork to get distance to the exhaust: 1 Quote Link to comment Share on other sites More sharing options...
bashplate Posted September 19, 2014 Author Report Share Posted September 19, 2014 nice, did you find the cherry bomb header made any difference, to how the bike runs? Quote Link to comment Share on other sites More sharing options...
Rollox Posted September 19, 2014 Report Share Posted September 19, 2014 I can say only something about the combination of copy carb+ cherry bomb header from shedworks + exhaust from WES + K&N in airbox: elastic and powerful reving from idle, absolutely no low rev stalling, but a little bit tiredly at high revs. Imho very good for vintage trial riding. 1 Quote Link to comment Share on other sites More sharing options...
