    Why Two Intake Gaskets Yamaha PV 1200?

    Ok so i pulled my carbs to install a primer kit, now that the fittings are in...i went to reinstall them but i'm confused. The kit i got from SBT has 3 orings, 3 paper gaskets for each single carb. Those were no problem. Then there are two long paper gaskets, with some type of raised rubber. When i removed the carbs only one oem gasket was under assembly. My question is do i really use both? And how..like stack them, glue together.

    Newer 1200pv motors had a plastic spacer between the carbs and the motor. One gasket on each side of the plastic. It all depends on what year you have

    I think they used a plastic spaced on the newer pv engines because the carbs would get hot and it would make it harder to start when warm due to heat transfer,it may be beneficial to find a plastic spacer and install it

    I have never seem a hard to start problem without the spacer. I believe if you have a cat delete plate it will not be a problem since there is far less heat buildup without a catcon. The factory added them in the later years due to the extra heat from the cat.
    PS: You need to use longer bolts on everything that goes thru the plate if you update with it, the original bolts will be too short and not have enough engagement in the threads.
