Swapped the engein out in just under 4 hours today including adding a 3 degree timing advance to the stator. Here are some pics enjoy. Realy easy to swap and not very time consuming

You've got nicer cupboards in your shop than we do in our kitchen ;)!
 
Just a new motor the other one spun the rod bearing when the oil tank cracked and ran out of oil.

Put about 60 miles on the Mod sled today!!! WO hoo that thing is much more fun than the stocker. the 10-12 ponies really seem, to make a differance plus the diet it went on.

Sled is really quick and has a good top end. Still doing some tuning on it though.

Allen's Airbox mod really helped and the tunign is pretty gppd I will have to play with the fuel maps a little. The three degrees more igniton timing gave it a little more snap
 
Where you getting the 10-12 HP figure from? Whats all been done? Ive decided to keep my Phazer so Im now interested in more power. Whats all been done to this?
What diet?
 
Don't the engines have to be stock in cross country racing?

No! Engines have to by stock if not in pro open class. There is a Expert 85 improved witch means he can a moded sled, only with bolt on mods. Timing changes are alowed in all class only to 3 deg + or -.

I have two sleds. I run two classes stock and improved stock. Anything goes except internal engine work

number came from Allen at ulmner racing we still need to get it on the dyno to be sure. I can tell you the stocker feels slow compared to the mod

Is that something you bought straight from Yamaha? How much was it? I'm just planning for if/when my motor craps out or if I get bored. Hah.

Can I ask (since youre telling anyways lol) is it just the timing advancement or anything else? What are yu referring to when u say "went on a diet"? Just curious Id ike to know the tricks lol.
