Lower Rpms

[jbfinn]

I have a 96 SL900, just got it running about a month ago, been trying to tune it in, I'm only getting around 6200 rpms, I have premixed the gas, and haven't burned throught that tank yet, and yes I have the oil injection still hooked up, it works fine, I just wanted to be safe since I had the engien out and replaced all the lines. Would that extra oil limit my rpm's? I have milled and re squished heads 155 psi, v force reeds, HSP water box, blue printed cyinders , wisco pistons, carbs have been rebuilt with new kits, hot seat CDI box, a nu jet 6.0 prop, bored out exit nozzle with a AAT on. any ideas? open for anything, thanks

Re: Lower Rpms

I replaced the fuel lines and vents also, It had 1/4 marine fuel line I replaced it with 1/4 regular fuel line, is there a difference? it did seem tighter, I wasn't sure casue the old hoses looked, well old and stretched.

Re: Lower Rpms

yes, extra oil could hurt your performance. get it broken in, with time your RPM's should come up.

make sure your carbs are adjusted properly.

Re: Lower Rpms

I have the kehlin cdkII no high speed adjusters, I was told those carbs came rich and not to re jet it. the plugs look okay a little dirty which I'm assuming is cause of the oil. If it was too lean on the high side I would have detonation right?
