Spark plug ???
« on: May 19, 2019, 01:35:14 AM »
Hey All!
Its time to get back on the bikes as summer is upon us here. 8)
The old 175 needs some love so I need a spark plug recommendation from you guys.
Has always run a bit smokey and I have located a box of NGK  B10ES plugs.
Are they to hot? Its a 1984 175 IT.
Thanks all!
Happy Trails

B10ES are too cold. I use B9EGV in mine but EGVs are no longer available.

You should use the recommended B9EG.

Thanks for the speedy replies!
Bike has the Boysen reeds and a Wiseco piston kit and for some reason the guy that sold me those parts said I needed to run with a cooler plug.
I see that the new 2 stroke mixes out there now seem to run a leaner mix with the new stuff that is out there.
Any thoughts on that?
Thanks!

Word of advice .....tyre oil and mixture threads are dangerous!!

But .... Pick your mix and jet to that, altering the petrol oil ratio will have an affect on your petrol/air mixture.

Personally I stick with a mix around the manufacturers recommendation.
