TE/TC 2017 TE/TX Plug choice BR7ES vs. BR8EG?

I see the manual calls for BR7ES vs. the industry standard BR8EG. I have a bunch of BR8EG's from other bikes, any reason I can't use it?

It's just a colder plug so couldn't see why not. Potentially could foul easier

One heat range isn't gunna make a drastic effect!!

no its not going to make a huge difference...... but why goof off from the OEM spec heat range????? BR7ES came on the bike BR7EIX is what is now on the bike (Iridium BR7 plug)

I ran the BR8EG in a race Sunday and it ripped. Very crisp.

My plug of choice is always the BPR8EIX. The protruded nose runs super clean and lasts. Cam.

I run the cheap 2 dollar regular br8eg in my 2016 TE 300 now for almost 2 years never a problem also use 110 leaded race gas mixed 50 to 1 with lugas oil

Ajax, You should try the EIX. You can actually tell the difference in how much better the bike runs. Its surprising. Heck I put one in my lawnmower because of that. Cam.

BR7EIX

I don't know if it matters but what premix ratio do you guys running Iridium plug use? I've been running 60:1 per the manual for at least 30 of the 49.7 hours on the bike. Seems goot at that ratio.

Plus, the '17s switched from a BR8 that the '16s and earlier bikes had, to BR7. There must have been a reason for it?? It is a new motor after all.

Stock on my 15 is br7es....per the manual

BR7EIX is in my 2017 TX300----use the OEM engineered heat range for your model, with the OEM recommended mixture ratio with the OEM or exceeding fuel requirement. they didnt just decide on whim what to use they spent doses of hours in r&d instrumentation and testing getting the most data to come up with the best engineering solution to put the bikes to market. my 2 cents. that's worth way more.

Oh, my bad, I thought i read either on this forum, or in a review, that they changed the plug with the new motor.
