Like I said above, clean and inspect every part sell. No generic for mass listings. All parts are cleaned and inspected by me. I am parting out this entire bike.
I will reply same day if you message me. But sometimes mistakes can happen. This part is not cracked or damaged. Threads are good.
Sometimes the cheapest option isn't shown. I will combine items and give good deals on shipping. This would probably fit most bikes of this era with the FCR carb. This part is in good usable condition.
All are unique to that. This is an aftermarket aluminum piece. All bikes are disassembled using proper techniques and tools.
