hi been useing mobil one fully synthetic, for the last 8 year's in both
of my vtr's and the blade, no cluch sliping issue's at all
fully synthetic need's to be changed more often.
Re: Semi or synthetic oil?
I've tried fully a few times over the years each time it's caused the clutch to slip under hard load, say launched from the lights.... Even tried it after I fitted street Racing Clutch and Springs and it still did it, changed back to Castrol 10W 30 Semi the next day never had any clutch slipping issues using the correct oil type for the bike
If honda waned you to put fully in they would have said so imo, as it is it they recommend you use semi and they know what works best

Re: Semi or synthetic oil?
Changed the oil in mine two weeks ago. Don't know what the black stuff in there was but I replaced it with Castrol 10w40 Power 1 Synthetic (same as I use in my CBR600 F2). No issues whatsoever......

Re: Semi or synthetic oil?

Re: Semi or synthetic oil?
you sound like my wombles old man with the "leave the exhausts alone" stuff
If honda had the money for research/design on every last inch of your bike to make it as racey as possible, your "everyday" bike wouldnt have a very "everyday" price tag at the dealership anymore
Also they have certain regulations etc they have to pass on exhausts and so on

10w30 is appropriate for our climate
I'm one of those 'gays' that spent time modifying the bike over the years but when it comes to what oil type of firmly believe they knew best

i'am all for moded storm's (take a look at my bike in workshop)
the point i was trying to make, was just because honda recommends 10 40w oil
(not even semi synthetic). it don't meen to say you can't use a different oil
HONDA (quote) 4 stroke oil. or equivalent motor oil, of spec's SE SF SG.
fully synthetic meet's all these spec's
yes honda has to meet, noise and emission reg's
but that's no excuse for crap CCT'S R&R and SUSPENSION (the storm's wern't that cheap when thay came out)
by the way .honda's been making a racey bike since 1992 called a fireblade atb
Re: Semi or synthetic oil?
Pretty much every Honda I've owned thats been '90's onwards has had the stcking tensioner issue, I always change them for manual jobs.
On the issue of Oil, my mate (a trained Honda mechanic) swore by Castrol oils for Honda engines. We always took this with a pinch of salt until a lad came into the workshop with an immaculate 1992 Blade.
A very well looked after bike but the engine was sounding like a bag of spanners. The poor lad was almost in tears, he'd had it almost from new and it was obviously his pride and joy. Turns out he always did his own Oil and filter changes and had bought 4 litres of Silkolene for the latest oil change. He told my mate he'd always used castrol up to that point, but as this had been on special offer he bought it. My mates advice was drop the oil and put Castrol in the bike.....This was done and the problem was solved, go figure.....

Which oil from silkolene had he put in that caused this?
