Hey! I have a IRK (Inner Rotor Kit) fitted on my 140 Linfan engine. I use the bike for motarding so the IRK should be the bees knee! It have been running fine (I think!) I don't know how to adjust correctly so have just adjusted it until it started easy and ran sorta okay! It now seems that...

Hi All I couldn't find any info on this so I hope somone knows or has tried this before. I have a CRF50 with 88 kit and have noticed that my throttle response is not the greatest. It somtimes is smooth and then other times it cuts in and out when i really give it to it. I have a Takegawa cdi...

hey guys just got my 09 and wanted just that little bit more power dont want an 88 kit just want that touch more pull up hills and stuff so has any body had any experience with these kits the kitaco one and would i need clutch springs and with the stock pipe will it still sound like a stocker...

those blue hi rev cdi's you see on ebay. they seem like they both do the same job and at the same performance. what do u guys think. they both plug into most pit bikes in the chinese market. opinions people. i like to see what you guys think. lets create a discussion! :cool: peace

hey im lookin at some irk's and found this one on ebay for $99 KITACO CLONE INNER ROTOR 4 PIECE KIT 4 pitbike - eBay Other Makes, Bikes, Motorcycle Parts, Cars, Bikes, Boats. (end time 11-Dec-07 09:32:45 AEDST) tellus what you think and if its trustworthy cos its a copy

i just ordered a kitaco supercoil the other day and hopefully it will fix my cutting out in high rpm but if thats not the problem then my cdi tht came with my irk is rooted so will any high rev cdi work with the irk aslong as i have a cdi harness to fit the irk? thanks

Does anyone know if you can cancel or increase the rev limiter on the Kitaco clone IR kits. My 140 lifan doesnt rev as hard now its got the kit fitted as when it had the old magneto. Anyone else noticed this?:confused: Sure it goes harder down low but it doesnt go as fast top end as it is...

I am wanting to do some engine mods to my bike and wondering if the ignition coil is the best upgrade for the money or is there a better upgrade i can do to my engine i am looking at spending no more than $300 i have a 125 cc ducar engine. i was going to put a Lifan 140cc in but now i know it...

hey gang , i was a little boared today so i put on my kitaco 75cc piston and barrel. ;) marked 49cc. look at the forge !!! mind you that i have put no gaskets and will not stick out as far when fully assembled. im wondering how much comression it will have.

hello peeps just an update on my bike, i installed the kitaco 75cc big bore kit. it rips a stock 50:D . has loads more talk. not as much as the 88cc limited kits and stuff:( . but it sure makes a difference:) . next up is a uni filter. then a cam, exhaust and maybe a carb. so if you want more...

i want to get a big bore kit in these school holidays and can only afford a kitaco 75cc kit. what are peoples thoughts on these kits? are they powerful? do they go well with a stock honda 13mm carb?
