Si-7
I use this in my son's 06 125 and H1R in my 250. Best perform great with no problems whatsoever. On tear down there was no scuffing at all. We run the ratio a little fat at 1:32 on both so there is some smoke. The Si-7 smokes a little more than the H1R. I would have to say that the cost of the H1R isn't really worth not having the smoke. The protection benefits are the same. Both bike's power valves are free moving with very little carbon. So little carbon that it can be wiped clean without solvents.

2 STROKE RACING LUBE
WHAT A GREAT PRODUCT! This STUFF is the best, my power level has increased at least 15% NO MORE SMOKE! Really a highly recommended pre-mix lube for small cc two stroke engines. Have used their products twenty years, it used to smell like head and shoulders hair shampoo 20 yrs ago, but today 2007, it is odorless! Good JOB AT bel_ray!
