I have an lc 400 husky and a 010 kato 300 and I run them on the same mix. I have run them at up to 100 to 1 for years. I rebuilt the husky in 011 with new bearings and seals used the piston and ring that were in it (std bore) and it runs a treat. Ive had it flat out in the desert and plugging away in the mountains, bogged at Harrow etc so far so good. bikes go good, clean smooth no probs. I have them jetted lean so I can get the bikes to pull clean from 100 rpm as that's what im usually down to as I struggle over the top of hills and in creeks etc paddling and pushing swearing and farting.....
Being aircooled may be a factor for your elsinore but lots of guys run the aircooled huskys at 50 to 1. you need to ensure you have a deep base oil to run lean ratios. its a personal choice and if I thought I needed another hp at the expense of a litre extra of oil per drum full I would run 25 to 1 as it appears that dyno work shows that the richer you run the oil there is a slight increase in hp.
A comparison using the same bike on the spot would be neat to do
a bunch of guys went to WA for a KTM run years and after a blast across the lake Lefroy area they asked what the fuel mix was and they said 100 to 1 Motorex. I run them all on that 75 to 100:1 now. including the whipper snipper the blower vac the lawnmower..(its a 4-) even the 510 gets a lung full of mix every so often (lazy)
don't run a new engine on these lean mixes. give a new engine plenty of oil for 2 or 3 tanks at least.
