I just put an SLP pipe on my 07 ported M8 and it is now very hard to pull over when it is cold. With a stock pipe it was not even close to this hard to turn over. With the addition of the SLP pipe I am now adding fuel with a BD box. Could it be too rich and gumming things up? After I got it started it seems to run fine. I checked oil consumption and it seems normal for the gas used. Any help?
M8 starts very hard after modds?

It was just a trail port, no head work. I ran it all last year with the porting and stock pipe. Only thing new is pipe and added fuel.
Check manifold for anti freeze. If you have a pinched o ring in the head it will leak and be hard to pull the first time until it starts. Also, in our area the weather has been COLD! and that makes them very difficult to pull the first time until the go through a few revolutions.
It has definitely been cold here too, below zero. Sorry for the stupid question, but what is the manifold? The sled runs well, so I don't think it is extremely rich.
Eric, would I gain more compression with the SLP pipe? I wouldn't think so, but what do I know. Just for comparison my ported M8 is twice as hard to start as my stock M8.

Temp's below zero will cause any sled to be hard to pull over. The oil is cold and thick. Also condensation forms on the inside of the cylinder walls, when you pull it though the first time it scraps the "ice" off. After a few slow pulls though it will get easier.

I am going to pull the plugs to see what they look like.
