What started as an innocent 'skill-testing' question on the general discussion board has turned into a confusing controversy: I said I would give some free movie coupons to the first person who correctly answered the question "What is the manufacturer-specified spark plug gap setting for the A35 engine?"
The answer I expected was 0.5mm (~0.02in). If you go to the TomosUSA (or Canada) web site, go to the 'showroom' (http://www.tomosusa.com/showroom.php) and then click on the maintenance schedule for any A35 bike you will see that the spark plug gap should be set at 0.5mm. On the other hand, if you go to the A35 manual (http://www.mopedriders.org/article_view.php?faq=2&fldAuto=21) you will find the gap should be set at 0.8mm. This seems like quite a significant difference to me.
I am more likely to believe the A35 manual, although I'm guessing that many people may have made the 'mistake' that I made and looked at the web site to find the gap setting. I actually just changed my spark plug and used 0.5mm as my gap.
So, I'm curious, what do people here use for gap setting, and is 0.5 vs. 0.8 (a 1.6-fold difference) really relevant?
