Hi feetupfun ,, my cota engine is together , already assembled , , so what I rember 200 cota is really 175 cc , and has same crank wrist pin of 125 , it’s a small wrist pin , I have ventured into looking into installing other brand pistons into different bike ,, close , not same usually different wrist pin & Bering , // #&% ,,, have seen on internet , if my memory , correct , some one installed a Vespa piston into a cota 200 , with a little matching, top of piston , for deck height , this was years ago , I believe he had it bored to ,,, , now , you have to research all Vespa for the Wright ,, proper wrist pin size ,, , 1 ,, then hope to match deck height , ,, I heard years ago the were going to mf more pistons for cota 200 ,, ya well there not enough bikes out there for them to make a profit ,, I suppose , if you watch ebay check once and while a 200 piston comes up , I know the the Oregon dealer. Had one 20 over , just this last few years for sale And sold it , so there out there , so France trial classic , is selling upon waiting delivery Tarabusi brand piston 63.95mm for E 177.00 you can put your email in for the waiting list , cheers info from larry

Hi ,, I have a cota 200 stached in the back ,, cota 200 pistons are very hard to come by , , southwest montesa , looks to be closed , as of 7/ 19 , due to health reasons no longer selling montesa parts , he left this message , on his web page , I. Called him few years ago , , very helpful , , upon info and ordering parts , SO ,, if you find a piston for a 200 cota it’s rare , there cycleservent in Oregon , states , he has a few cylinders for 200 , , ,,' I working on my bultaco pomeroy replica , 360 assembling a engine , I purchased on ebay eng & frame match , cheers ,, ps ,, just rember , there was a chap eastern central England , that was selling used montesa parts, on ebay , , I don’t rember his name Like , it was about 7 years ago I ordered part from him , on ebay ,,he had lots montesa used parts ,, you might call around bike dealers , repair shops to locate him he had a few 200 cotas was parting out ,, really ,

Hear is my spark plug story NGK maby 20 30 hours upon start when cold choke on , fouled out , removed cleaned still would not start , checked spark laying on head , kicked over , noticed spark traveling from top to side of spark plug , not electrode , , must burnt I suppose did note have same had old champion off mopar car looks lot hotter cleaned with emery installed first kick starts up , ,,, old champion must be 25 years old , in my opinion champion spark plugs rule , will change to proper heat range later , and probably purchase a champion brand ,,, cheers
