im trying to get ahold of him. i purchased his old red 85 GS from the guy that bought it from him.

main reason is to figure out if i have a SP motor or not. in his posts on the forum its says the car has a stock port rebuild but it def. sounds like a SP motor. ive even tried adjusting the mikuni and it still has a lumpy idle and really quick throttlev response

and way to tell with the motor in the car? can i pull the exhaust and intake mani off and take a look?

 

Thats a nice car. I bought some wheels off of him a few years ago and met him at an autocross over in Columbus OH. I pretty sure its a stock port. The combination of a mikuni and whatever the timing is set to will make the idle seem lumpy until you get on it. Lareg 2 barrels kind of run like that. I have a Dellorto and its a similiar setup with a bit of a lumpy idle down low. I'm pretty sure its stock port.

thanks for the info. the car is alot of fun. i messed with the carb a little on my lunch break today and i got the car to idle about perfect and the intake mani is ice cold as well.

 

If you ever want to make the drive, come on over any second Sunday for our meets. We have a thread going for it in the SE section. I'd like to see that car again. It was a clean car for up in ohio.
