ENGINE 125CC YTX

I LOVE this Apollo machine. The YTX engine is awesome. I blew out my new Apollo (original engine) intake valve after only 2 hours riding time. Misunderstood the instructions as written. I removed a band thinking “Band” meant a zip tie. NOW I ONLY need a cam timing chain to fit the 32T cam gear in the new head and block I purchased through Amazon. This will fully restore the original engine which used a 28T cam gear. Can you SEND me the correct timing chain for the 32T cam gear or refer me to a major parts distributor? Payment is no problem. AFTER SOME LONG WAIT TIMES getting the correct parts and the tools needed to repair, I decided to purchase a replacement engine. I’m SO HAPPY I did. Now I’m looking forward to restoring the failed engine. SERIOUSLY considering purchasing a new Apollo dirt bike for my uncle. Thank You Apollo! RELIVING the early 70’s during my motocross years.
