1. My spree idles kinda high, and without giving it some gas it starts to pull slightly like it wants to move, and if i let it go on its own it will slowly speed up to about 20mph without giving it any gas. ( i have tried adjusting the screws, but if i take it out 1/16 of a turn it the revs lower and starts to die...?)
That's a sure sign that your carb and/or fuel system needs to be cleaned and inspected. If you are not experienced with any of this, I suggest taking it to a professional to have it worked on, otherwise clean thoroughly and reassemble. Remember, cleaning your carb doesn't involve merely spraying carb cleaner into the carb while it's running. We're talking full disassembly.
2. My spree on flat ground gets up to 35 mph, easy, ( i weigh 140lbs) and up hills about 28ish mph. and down hill 40-45 mph.
while going down hills im afraid something will break, i dunno its revving REALLLLLLLY HIGH ( because of the speed) . in this situation, would you recommend keeping the throttle pinned, or letting off the throttle completely? the speed stays about the same because of the gears i imagine.
The motor revs that high because stock gearing is very short, similar to coasting down a steep hill in 1st gear. The motor in stock shape doesn't have power so the gears need to be setup for that, hence the higher rpms. If the engine is winding-out, back off the throttle.
3. driving full throttle ALL the time is ok?
This is a harder question to answer. For someone who knows how to tune their bike and knows the condition of their setup, I'd say yes. For the novice or inexperienced, I'd say no. Without going into too much boring detail ideally you want to ride varying the throttle while you ride.
The idea behind WOT running over extended duration revolves around 3 key factors (not easily balanced by a novice). The CHT (cylinder head temp) at WOT, oil ratio and fuel condition (jetting) at WOT.
4. cheap gas or premium... i know it only costs me about 72 cents to fill up and i can ride all week long.. so price is no concern? i know premium is used for higher compression engines so the combustion is controlled more, but does it matter in 2 stroke?
A combination of ambient temperature, compression and load (therefore heat) is the main factor determining what octane you should use. For 90% of the bikes I've seen, regular is just fine. You don't get more power using a fuel with more octane than your engine can use, in fact it'll likely rob you of power.
5. i bought 2 petcocks for 86 sprees,i have a 85 and 86 and found out the hard way that it wont screw onto the tank of the 85. is there any way to adjust the thread or do i have to get ANOTHER petcock... i also heard someone on this forum made their own petcock. is this a possibility?
Both are different I believe, but I'm not 100% certain.
6. Tires.... best/cheapest place to buy them online?
No idea, we buy ours locally. Our prices aren't cheap either since we have to pay extra for aloha tax (shipping costs to Hawaii is terrible).
Reliable and dependable tuning from 15+ years of experience.
