It annoys me that people post information that is incorrect. Zorro and Phil are speaking a different language on this 2nd page the person I pointed out has since gone quite. Figures don't lie. Referring to you comment about being on point, 30% more volume and 9 AFR is fact. Zorro is correct in...
110% utter rubbish. E85 will not harm fuel lines ,gaskets or fuel tanks in anyway. Maybe you have been drinking methanol which will do as you describe. In my experience Zorro, 30% more volume is required from a petrol tune, aiming for 9's in AFR. Go for it, like you said only question would be...
ive warned you once about talking rubbish about the v2 head. the power delivery is depandant on cam profile installed and has nothing to do with the v2 head! saying that.... a stock cam wont deliver the necessary velocity of the intake charge due to its lift and duration,(lack of) Now a cam with...
I posted a scenario here on what happened to this engine and didn’t prejudice with my knowing that the 2 most knowledgeable guys on here would confirm my own assumptions. Terry hit the nail on the head first and then Sean offered some sound advice and used this example as a lesson to be learned...
Mate you should not spruik such rubbish and scare potential pundants of trying a V2 head...a engine is an air pump and the only temperamental aspect of tuning this air pump is the idiot on the end of the jets and stoich does not favour one brand of head for another. You have a point on...
It droped the inake valve. Have not removed the head but stuck torch down intake and the cam rotates but intake valve does not. Its still sitting in the guide and i would have to asume its as bent as freddy mercury...so is it time for the v2 head and piston or rebuilt and who has the parts in...
i bought a atomik with a yx160. its got about 30 min on the motor. I had the thing WOT in top gear about to do a plug chop and then lights out!!!! The thing still has spark but sweet f all compression on the power stroke. ive pulled the rocker covers and valves are still intact. I imediatly...
The IRK is absolute rubbish!!! sure they spin up super quick to half revs but then the lack of a strong spark results in it breaking down from there on, P.O.S!
Problem all fixed. I installed a lifan ORK. I had to machine down the stator plate 3mm to fit the yx engine. Its a different bike, even sounds different. The moral of the story is that IRK's are a POS. They are well enough made but in my view don't induct enough volts. The lifan rotor was...
Hey motorman...i think you maybe a little confused? that photo is of a roadrace bike im building from scratch and the purpose of the photo was that ive had more trouble with the bloody IRK for a atomik yx160 than building this bike from sctatch. the ignition on my race bike is worth than the...
I think motor man said it well. IRK's are crap. The build is a ducati corse engine, alloy frame by me and all the other stuff is "click- add to cart then check out" I think all ive done is made what pathetic spark the irk generates and made it efficient enough to at least run the bike. Imagine...
update:
Replaced the coil for a quality chinese one...(if there is such a thing?) Much much better but still has the miss but its much further up the rpm range. The spark is still weak as **** but maybe thats just as good as a irk gets. I followed seans specs for the carb as well. Its so crisp...
