A nice sentiment Rath, one that all contributors to this blog will agree. Gator has certainly been the lynch pin to this wonderful thread that has wandered onto every topic known to man.
A personal welcome back from me too Gator.
Like you Richard, I have been quiet lately due to ill health and despite having two lovely bikes in the garage, have rarely been out.
80% of motorcycle accidents occur when the rider is unfamiliar with the machine s/he is riding. Not loaning the bike could save a life.
Detonation killed the piston and it's a topic beyond the scope of this modest post. Fuel is major factor, and it seems you guys cannot access ethanol free fuel at 98 octane, which is available here still, but for who knows how long.
Spend some time reviewing threads here and on the britbike forum where you'll find a wealth of knowledge about detonation, initial bedding of the rings, and running the engine in.
In the absence of high octane leaded fuel, these old engines are very susceptible to detonation which places pressure on all aspects of tuning and riding style, to avoid holed pistons.
Like others here, I do hope you'll be back on the Bonnie soon, as they really are a joy to ride, despite the many problems we encounter with them. RR
Gator I have it seems no Ethanol Free stations around me but I am still checking. I'm thinking of either running race fuel or an 4gln of Av Gas to 1 gln 87 unleaded which would give me a 98 octane mix. Sucks when your ride keeps doing that stuff to ya all over the fuel. Driving 50 miles to buy fuel in 5 gln Keep Cans can be trouble some too because then you need to add some Stabil to it as well.
Chuck - yeah, it's trouble, but not as much as rebuilding a top end. I use the Marine Stabil which is supposed to last a year, and with the 35 mpg my Bonne gets, that won't last long. Hard to believe I get a consistent 50mpg on my '97 Harley Wide Glide and only 35 on the Bonne with less than half the cc's.......
We only have ethanol blends here in Texas, but I do not run ethanol fuel in my classic bike, classic cars and do my best not to put any in my modern bikes. I buy a 55 gal drum of Phillips racetech fuel that is ethanol free and keep it in the garage. It's 100 octane, nothing radical. When I ride the modern bikes I try and stay within the tank's mileage limit (about 250 miles on the Tiger 1050) so I don't have to stop at gas stations. When I trailer them somewhere to camp and ride, I take about 4 5 gal cans (20 gals) with me. If I go far enough where I must stop before I get back to my canned fuel, I'll try and put in just enough to get where I need to be, and then fill up from my cans. I know this is not a practical alternative for many, but my stuff sits up a long time between rides and it's nice to know the gas that you left in it is still good and not attracted moisture when you're ready to saddle up again.
If I ride for a weekend trip or so, I know I'll have to fill with ethanol blend, and just try and plan to burn most of it before I get home. Worst thing is, the EPA is approving higher blends of ethanol that will really mess stuff up. When this happens, I will get some auxillary fuel containers and carry on the bike for mixing purposes to keep the blend as low as possible. What a mess.
Good to see you're still here Gator,
Look on the bright side, at least you know what to get your wife to buy you for Christmas, a pair of Bonnie pistons
I'm sure that once you've rested over Christmas you'll have the courage to tear into the Bonnie early next year.
Take care of yourself
Hey, Tiger - how can I get the 55 gallon can of race fuel? And what is it, $5/gallon? More? I can put it in my garage or one of my sheds.
Next question: how do you pump it? Don't you need a special pump for gasoline?
