A few more MPH?

I have a 1998 honda elite SR, i have drilled the out the washer on my pipe and taken off the clutch restrictor. I plan on getting a new Air filter instead of the stock. Is there anything else I can do (not shaving the head or boring it out) that will give me some more performance.

intake mod, advance your timing.

I dont think it has a restricted intake, best bet is a sub $100 60ishcc bore kit, install is easy and fast, 4 hours tops.

No No No. Forget those two post above this one.

If you are only looking to get a few more MPH (and you dont want to get a bore kit) get a gear change.

If its a 98 (or any 94-01) Those motors are awesome. They can be highly tuned, and can be make super fast. Tons of parts are availably. If you don't want to 'bore kit out' you can buy bore kits. Pre-bored cylinders, bigger pistons, rings, and a head. All for as low as $110. (can range up to 275 for top of the line stuff). Typical for your bike is a 72cc. thats about 50mph to 75mph pending on your carb/tail pipe.

But yeah, 9;1 gearing. 9:1 gears are good for the stock bike. They will give you more top end, and they wont hurt your take off to bad.

if it is a dio motor, AF/16, the easiest way to get a few MPH is to do a simple derestriction. Im sure you already have done removing any restrictors behind the variator, sometimes theres one in the intake behind the carb, and if your going to use the stock exhaust , make sure the restrictor washer is taken out, or it might not be there, just check to make sure. If you dont plan to spend much just do the basic de restrictions and go bigger main jet & derestrict the air box.

You need to find a derestricted pipe, you should be looking for a v-8, typhoon, R-1. A Pg long is to much for this application.

Rejett your stock carb, im guessing maybe up to a 95 or 100, they sell those sizes for a stock carb. Use the stock airbox, most people wil tell you take it off, you can try but i l bet it wont run as good. You might want to look inside the airbox, sometimes there is a smal rubber snorkel inside, pul that off then reassemble.

Change your rear clutch springs, 3 small ones. Get some 1500rpm ones. this wil give you a little more stall and give it the "wham" off the line. Center spring for a stock motor find a 1000 rpm, even a bran new stock replacement would be awesome. That might be more like a 900rpm.. not to sure on the exact rpms.

weights, the stock ones are either 8 or 8.5 grams. Those work well. you can replace them if needed for your weight and riding style.

This is what i do for brand new SYM DD50 and they get up to 45mph pretty easily..
hope this helps

PS dont mill the head.. higher compression mostly add to the off the line & heats the motor up faster. The gain to me is not worth the trouble unless your racing it.

change the stock gear ratio to 9 :1 :1 use the stock air box just open up the plugged end, main jet is #87 polini green clutch springs, daytona red center spring, 7x9 weights= thats all!
