cam timing
Hi, I have a GS1100 motor that I'm rebuilding. So far I have a 1325 F.B.G big block, mild port job on 1100 head, gsxr750 dot cams and rs36 carbs. My questions are, what should the cams be degreed to and where should I start with the carb settings, main, needles etc. It's not a drag bike, just street, with the occasional stop light blast.Tags: None

For what you want to do I would put the cams at 107 exhaust and 105 intake where you jet the carbs at will bet deturmand by the build and compression on your motor and you elavation you live at. Just start out with the Mukuni factory setting as most suggest. But I have found that they run better jetted richer than the factory settings.My stable

I have a similar engine that I race. 1327 with 10.5 to 1 compression. rs 38's needle in the middle. 125 mains. Cam Motion G7 intake and G4 exhaust. Middle of the road porting. With the cams degreed to 107 for both, the builder got 180hp...Of course, he was a very knowledgeable engine builder...

Thanks for the replies, I have the factory welded crank, welded angled gear hub, 750 oil pump gears, 1150 oil cooler and cover, APE studs, case and cylinder also a top end oiler. I am putting it in a 82 Katana so I dont need the tach drive. Rapidray, it's coming together slowly but if I run into any problems I will get in touch and thanks. I'm gathering 130 mains and the needle in the middle is a good start for the RS36 carb.
