hi guys just wondering if anyone can help, is there a ngk spark plug available for the slant head ?
b6hs is a good plug for both 48 and 66cc engines.
will it hit the piston as the plug that was taken out is short where it screws into the head ?
Not on mine, I run a grubee 48cc slant head and use the b6hs in it. If it is the same china girl engine kit you should not have any problems. Get the piston at top dead center and screw the plug in, then screw it out and see if the gap closed up if not it did not hit.
I run the same plug in a 66 that works fine.
All 5 of my HT builds use that same plug...no problems.
I have a 48cc slat head too,but can't find a place with that nkg b6hs to buy from.Please tell me where to find it or a nother brand....Thanks
Pep Boys, Auto Zone, O'reilleys, NAPA Auto Parts etc. They can also cross reference it to AC Delco, Champion and other plug mfrs for you.
O'rielley's here stocks the b6hs.
And if you really can't find the plug Sick Bike Parts lists them.
anyone know if a ngk bp5hs or a champion L90c plug will fit a boy go fast 66/80cc slant head motor. my stock plug crapped out on me so i need a new one. and my auto parts store only carries these 2. or should i go with the ngk b5hs plug off of sick bike parts?
The "p" is for the extended tip, it works in my slant head 48cc. With ngk the lower the number the higher the heat range, run it and do a plug check or chop as it is sometimes called and look for signs of heat related problems.
Phinseth I running the ngk b6hs its great plug it's not as hot as the b5hs I would start with the 6 series first if not hot enough change there cheap enough to change.I can get them at most auto parts stores.
I use the BP7HS and have no issues I also use 2 aluminum head gadgets though however it never hit the piston when I had just a one.
I just put the second one on because, I read told me you can get more compression or some thing
I think you have the gasket idea backwards, adding a second gasket lowers the compression.
Yes Greg your 100% correct in fact before i put in the second gasket I was getting blow by out of the single gasket when I swapped to angle head because of to much compression.
However when I put in the second gasket "Even though one would think this will not fix your blowout issue " it did & the only reason it did was because " like you stated Greg "it lowered the compression" & stopped all that black oil from getting all over my bike and my legs
