Honda Spree and Elite 50 Forums

Hello all!

In my owner's manual, it mentions "If driving at high speed for long distances, switch to colder spark plug".

What is the standard? What is considered "long distances"?

I need inputs guys.

Thanks.

Greetings:

BPR6 HSA is standard.
BPR8 HSA is the plug for very hot climes and/or prolonged WOT.
Honda lists a BPR4 HSA for trips north of the arctic circle.

NGK has a BPR7 HS (No "A") which seems to be a good compromise between the easily-fouled 8 and the hotter-running 6.
I found mine at O'Reilly's for under $3.

Thanks!

Yes both 6 and 8 are mentionned in the book, and I did see something about the 4 on the net, but nothing on the 7.

Still, is riding at full speed for 10 minutes considered enough to replace to an 8, or is it an hour?

I don't ride very far, the scoot is only for fun, but I'd like to keep it as long as possible, and I certainly don't want a hole in the center of the piston...

What I'll do is get an 8 in case I decide to go to work with the scooter, which is a 56km commute, just for the fun of it. If it gets warm (yes it does up here in the Great White North during the summer), I'll get a 7 as per your suggestion.

Thanks again.

I find O'Reilly is bogus to the EQUIVILENT of a $3 'bill.'

If going WOT over 1 minute I would run the 8.

Is running the 6 WOT for extended time periods really going to mess things up & if it does why/what will get messed up? What about the Autolite 4123 from autozone that is listed here on the forum as a replacement...anyone know the temp range on that plug?

Greetings:

Running a Spree or stock engine is not the same as a modified mill. The power output determines the heat production in large measure. Outside temps, oil ratios, jetting and yes, plug heat range add their variables, but an engine producing 3-5 HP is less at risk than one putting out 8 or more at RPMs never anticipated by Honda-san. If you've run your Spree with a #6 for several minutes at WOT without self-destruction, there's your evidence that a 6 is just fine.

Sounds like the best way to test. Will post pics of results tomorrow.

i run a B7HS ngk and it works good.

I'm having a problem finding a 6. Local owned auto store and Autozone don't have it. I like the color on the 6, nice gray. Conditions are variable, seldom WOT. What's next best option after the 6?

Hey,

I have used the BPR8 HSA for a while now and it seems to fit my bill nicely. I often take long commutes on the Spree been at WOT for several miles.No damage to report thus far

your plug should be a nice lite tan color not grey. grey means it's running to lean or to hot.

I digress. Since I'm on the semi-colorblind side, it may be tan. But it's not LIGHT gray or whitish. It's a darker color, clean and not sooty.

I bit the bullet the other day, as I was in the Honda store anyway, and bought a couple of #6 plugs for $3.60 apiece.

Ok, got myself a BPR8HS, I'm told the HSA is no longer produced by NGK , I'll be able to try it and check it after a while, if it fits my style better than the BPR6HS (again, I'm told the HSA is no longer available) since I want to ride at max speed for a long commute I want to do. The "A" meant it was a cooler version, sort of a half way between 6 and 7 (7HS, 6HSA, 6HS, etc.)

Will report later. The 6HS I removed was tan colored, and I only did city driving. If the 8HS is fouled, will go back to the 6HS. I did notice a lack of power immediately, but it was very humid and that's normal, so I read on the NGK website's tech infos, did loose a few km/h. Will wait to have a beautiful warm day to really compare.

By the way, forgive my ignorance, but what does "WOT" stand for?

(again, I'm told the HSA is no longer available)

They lie. I just bought two BPR6HSA plugs from Honda house this week. If that's a local auto parts house, they want to keep your business by selling you something else. But buy what works and is available. I'm 25 miles from Honda House and understand. I had to be in town on other business and also to order a tire for my Helix or I might not have bought it.

WOT can mean many things but in this context, it means Wide Open Throttle.
