baldilocks Posted February 10, 2017 Report Share Posted February 10, 2017 Less oil = more friction, beyond a certain point, would this mean less power? Quote Link to comment Share on other sites More sharing options...

I asked specifically because i had to run a slightly hotter plug in my evo. How do you like yours? My (just purchased last week) Brand New 17 Ice Hell 300 plug also sooted up and stopped the bike from running today after only around 6 hours on a New bike! Lewisport said to change the plug to a 4 plug. Pulled the existing plug, a 6. Black and sooted big time. So perhaps they'll swap to a 4 on the 18s? BTW - Lewisport recommends 130:1. I am running 93 Octane ethanol free fuel. Hmmmm..... Quote Link to comment Share on other sites More sharing options...
heffergm Posted December 1, 2017 Report Share Posted December 1, 2017 You need to adjust the air bleed screw. I'm going to bet your idle is pretty low, and you'll find if you get the bike in sixth gear and give it a handful it'll bog and or stall entirely. You need to back the air bleed screw out until the idle comes up. You'll know when it's right because it'll pull sixth gear cleanly. Quote Link to comment Share on other sites More sharing options...
jsp Posted December 7, 2017 Report Share Posted December 7, 2017 I had mine back to vertigo as I couldnt get the tick over as I liked it one minute it was ok the next it was racing, they found that my airscrew wasnt where it should have been. but I'd never messed with it I only alter the tick over by the throttle stop on the kick start side so i dont know if they can work loose Quote Link to comment Share on other sites More sharing options...
pmk Posted December 8, 2017 Report Share Posted December 8, 2017 One point not mentioned in the previous oil discussion, is flashpoint of the oil. Yes the oil, however much or little is mixed with the fuel is headed somewhere. Most likely out the exhaust. High flashpoint oils seem better for and recommended for high rpm, higher output engines. Lower flashpoint oils tend to burn cleaner, and are oftened recommended to run a lower premix ratio, the higher the intended rpm. Oils that do burn, may produce carbon over time, while high flashpoint oils tend to remain wet. Synthetics of high flashpoints tend to leave a strong but easily cleaned oil layer, while castor oils tend to gum up unless run hot and often. With current technolgy, coatings, and exotic materials, plus some very high quality oils, the time may be near for mix ratios even higher tha 200:1. Sometimes though, our comfort level and instilled experienceholds us back. Admitting, I even consider oil inexpensive vs engine repairs, provided the engine performs correctly. Not debating anything, just sharing info. 2 Quote Link to comment Share on other sites More sharing options...
GazTemple Posted November 10, 2020 Report Share Posted November 10, 2020 Hi all, I have recently rebuilt my '18. Long story short, i got it running and idling nice last week, still bedding in a new piston and newly plated barrel so was just running it on the stand for 5 minutes or so at a time to go through heat cycles. Anyway, it has now started running really lean and is not wanting to run right at all. I'm thinking that the injector may have oiled up a bit? is that possible? I dont want to have to take the engine out again so any ideas? Have been running 50ml to every 5ltr. Think i'll reduce that having read all the comments above. Cheers Quote Link to comment Share on other sites More sharing options...

You were running a bit more oil than that... Put in a new spark plug (BPMR6A NGK). Then, run the bike at idle for a minute or so, but get on it and ride gently to warm it up. When the fan comes on, then get into 3rd or 4th gear, and open it up a bit... Idling doesn’t generate much heat/pressure in the cylinder... makes the oil kind of bog up the works... The real trick for longevity is to keep idle time to a minimum.... 2 Quote Link to comment Share on other sites More sharing options...

Big thanks to Nick at Vertigo UK for all the help. Quote Link to comment Share on other sites More sharing options...
