the line below jumped out at me though......................

I think Motul 800, Castrol A747 are thick esters as well (See subsequent article that follows)...........and I have written before which is overkill at rich ratios for engines under 9,000RPM.
2 stroke oil (again

Controversial....my gut instinct says 'no' but it is a free country, and if they're not affronted themselves then I don't feel I have the right to be affronted on their behalf. :baddevil:

Thank feck most of us ride above those pussy revs..........and I have written before which is overkill at rich ratios for engines under 9,000RPM.

zzzzzzzzzzzzzzzzzzzzzzzzz............................sorry, started to read the learned articles in this thread and just nodded off. The step change for me was Bardahl VBA and out of curiosity Mr Google replied: http://www.bardahl.nl/uploads/media/B56000GB.pdf.

Just picked out a small section of drunkmunkey6969 post
Ok so with all the specifications of their major 2T oils, I can conclude that riders who use Motul 800 are wasting their money mixing it @ 20:1 or ratios less than say 40:1 as the maker states. This is because like Bel-Ray MC-1 that is much heavier still than 800 to mix it at rich ratios will create an amalgam of oil/fuel that will not ignite to its optimum level. At that ratio it will simply quench the flame.
Using heavy 2T oils at rich ratios will not alow the bike to operate properly by restricting the proper flow and atomisation of the fuel/oil mix to pass through the engine. This may necessitate the use of larger pilot jets (as some riders have found).
Motul 800 would be ideal in later model bikes with power valves and chrome or Nikasil type bores at ratios around 40:1 or leaner to 50:1. (Ideal oil to use in later model KTM 2 strokes etc) I would still run as much oil as I can get away with if I had a late model 2 stroker perhaps starting at 32:1 and work down towards 25:1).
For VMX's now running Motul 800 @ 20:1 save yourself some money in purchase price first off and switch to Motul 710 (or even 510 semi synthetic that is more than enough) at 20:1 and then experience your bike running better all round with better throttle response, cleaner spark plug, less oil hang up in the exhaust and crankcase, perhaps less thicker smoke. It should also lead to a greater wear reduction as the oil will migrate to the sliding surfaces better.
800 is 135 Cst and 710 is 50Cst, (remember don't run 710 at lean ratios......bye bye motor) much lighter by almost 2.5 times and better for rich ratios allowing the oil to lubricate the engine better, mix more thoroughly with fuel, with no hangup inside the engine. With 800 @ 20:1 the rider may face starting difficulties on a cold engine, or with old fuel (oil separation happens more with thicker oil falling out of suspension) or in cold weather.
Perhaps i was just lucky but i had motul 800 left over from enduro bikes and used it in my Mb honda 205 then my classic rapido 225 at 50/1
I did town/motorway and euro runs.
The 205 went to someone in darlington when i finished with it and the rapido went to cezeta and i believe both still run ok.
Only recently have i changed to rock oil and listened to everyone's scare stories of bearings seizing if you don't run at 20/1 why are going backward to the original advice from the scooter manufacture

TS1 and PX stay in the garage (future barn finds) out on the GTS 300 when I go out on a scooter.
I know I’ll get there and back
