Like when you said:
I have not blown any cylinders. The only heat issue turned out to be a tach pickup wire that was touching the MLM and started to get hot, and there was an issue that we discovered after a couple tests where the tire was rubbing on the kickstand (video 5), and created some heat.3. This section is pulled from your other post where you blew like 2 cylinders.
okay my bad on that
As for the "cheap stuff" oil I was talking about, that was just some stuff I picked up to get it initially running with the old piston before the BBK was done. I drained the oil reservoir and added new lines. It is running HONDA GN2 INJECTOR OIL in the pump and in the premix.
well how were we suppost to know this? All you said was ran it on the cheap stuff until the gn2 came in.
As for deleting the pump, I have a very legitimate reason for NOT wanting to do that, and I have a legitimate reason for NOT running a premix in the tank.
so you just said you will not be running premix beside the pump then tok or just as itself? Agin clarification, pictures, charts...
Brent over on the 49cc scoot forums was talking to me about this as well. He suggested a 40:1 ratio might be a better choice and I agreed, but rather then repeat myself again as to why NOT, lemme just quote myself:
Also, I don't have charts (yet), but I will get them. Shawn and I both had business to tend to and were kind of limited to what we could do for dyno runs so we chose to do just extremes.That will possibly be something I may look into doing later on down the line. For now though, I'm leaning more towards keeping the pump and zero premix in the tank for one key reason... The Spree is for my son with Autism. I would then be placing him in a situation where he would need to figure out how to do the premix every time he put gas in. A long term goal for my boy is to step him up to a bigger scooter, but at this point, he only wants to drive the Spree. Doing premix for him till he finally gets the courage to try a bigger bike is no big deal, but then I may be faced with a reality that he simply will not do that. In which case, what I ultimately might have to end up doing, is removing the BBK and taking the Spree back down to it's stock configuration.
But again, I can agree with 40:1 as the probable safe bet for the BBK. If the pump is in fact, putting out 50:1 like some have claimed, then it won't be too far away from a 40:1 ideal range, and with that, I'm guessing a good squirt of oil in the premix container should be good to go. I know I have seen some "claim" to get better revs when they delete the pump, while many other's argue that the pump is NOT bad at all and just gets a bad rep.
Pump .vs Premix gets ALOT of debate and alot of pros and cons from people who will swear by one or the other.
I think for the most part, Honda makes a d*** good bike and I have much faith in the pump. If it was a TaoTao 2 stroke with a pump though.... yeah, that pump would have been gone before even taking a first ride.
I just wish there was more data out there for these older scooters so calculating precise premix would be easier. But, one problem at a time is the way to take it. For now, I just need to get the BBK WOT stable and idling correctly.
*Lid and filter in place, no holes
*lid off, just filter
*no filter, no lid
I figured those 3 key run types would show what is happening with it at different levels... TOTALLY open to thoughts or suggestions before trying again.
The findings of too much oil, are based on the excessive amount saturating the probe in the muffler. If you think this should be OK, then yeah, would love to hear any thoughts on that as well.
If your planning on going back stock and already have to premix then whay havnt you already pulled the pump for these test. The pump is gonna be the death of the bore, I could garentee but I dont need to do that. Also what exactly are you trying to prove here. That it is a sturdy bore? That it can.run without an airbox? It can run with an airbox withiut holes? Your making this post very confusing. One post is focused on top speed the next is rather it will be good or not for your son as im reading it.
