'11 SE slow poke

[dirkdiggler]

My buddy's SE pulls 10800+ on a long lake run with a full clutch. He has seen 117mph on the speedo. This sled has almost 2000 miles and he uses only 93 octane fuel. He was actually thinking of adding weight to his clutches. Also if you look on the Yamaha parts finder the XTX has a 3.6 rivet in the tip of the weight and the SE has a 2.4 probably due to the gearing difference. We are going to add the 3.6 to the tip of his SE weights to see how it pulls it.

I would have to look at the dyno sheets again but I think that might be a great idea. I think the apex makes peak power around 10300 to 10500. I'll check out dyno tech today and post later where peak power is

The Apex appears to pull great HP numbers from 10000 all the way to over 11000 Pre and post production.

Now who said they dont make power at 11,000,that is where all mine have been clutched to run fast,and all of them have run 117 plus on the gun,and they were all pre 2011 models.

Wow I thought they leveled off at 10500. Maybe we will leave the clutches alone!!!
