My 2000 Elite SA50P quest for 45mph
Posted: Thu Mar 28, 2013 12:42 pm
Hi All -
First off I wanted to say this site is a wonderful resource! I've been reading for hours every day. I just picked up a 2000 Elite S last week. It has 4500 miles on it but the previous owner went through the engine and replaced rings, seals & gaskets. The carb was cleaned and it has a new 90/90 rear tire.
When I first drove it I could only get it up to 30mph. My goal is 45mph without going the bbk route.
I pulled the exhaust off, the washer was still there so I used a dremel and grinding stone to remove it. I checked the oil pump and it's zip tied open and he was also running a little oil pre-mix in the tank. From what I've read this is because the SA50P oil pump won't get you to the 32:1 ratio. Pulled the plug and replaced with a new NGK BR6HSA. The old plug looked fine based on the color charts in the wiki.
The airbox had the 2nd tab punched out and then it looks like was glued shut again, I left it covered. He didn't remember what the main jet size was when it cleaned it so I'm assuming it's still the #68. I pulled the variator off and the restriction plate was already removed from the back. The rollers looked to be in good shape with no flat spots.
After putting it all back together I was able to get up to only 34mph GPS. I was really hoping to see closer to 40mph.
Parts that I've ordered so far:
#85 main jet
Speed variator kit from Taz
9 to 1 secondary gears from Taz
Should I hold off on riding it until I get the #85 main jet installed? Do you think what I've got planned will get me to 45mph or do you think what's already done should have me goign faster than 34? What other things could I look for? I was considering a new belt because the previous owner said he didn't change it out.
Thanks!
