  1. Hi Guys, Does anyone have a big bore kit recommendation for a 1978 Honda XL100? 150cc would be ideal; I'm not looking for a huge increase. I did see some talk on old forums suggesting Powrell had big bore kits for old Hondas, but it looks like they closed down in 2019. Thanks all, any recommendations would be much appreciated! #newb
  2. 2006 DRZ400SM. 434 Cylinder works big bore, Stage II hot cams, MRD exhaust, E model CDI, FCRMX39 Carb I bought from TT a few years back. I have hanging idle issues. I had my fuel screw stuck closed? Don't know how I did it but I had to take it off to fix it. So I have it at 1.5 turns out for when I reinstall it, I plan to modify jetting first as needed, then try her out. Anyway I have the following Jetting Slow Air Jet = 200 Main Jet = 158 I think I need a 160-165? Slow Jet = 45 Starter Jet = 80 Needle = EMP 3rd clip from top. Wire vs. O-Ring mod. It falls a little flat on top since I put in the smaller cams I had to 9.58 lift old Hot Cams before. So I think I have the thing about right just looking for advice.
  3. Hi, I'm after recommendations for a big bore kit. I'm not after massive horsepower and I'm not looking to do this right now - I just thought that I might spend some birthday money and have a kit handy for when a freshen up is required. I want reliability over horsepower and an "all inclusive" kit over bare bones (requiring other purchases). I would prefer to buy off eBay (and ship via the global shipping program) as it solves the issue of import tariffs and duty at my end. Any thoughts as to brand, reliability and suppliers greatly received. I am aware that there may be other parts of the bike requiring attention when a freshen up is required - maybe valves / head and cam chain. Any thoughts on what else?
  4. I was wondering what mods I should put on my 2006 Honda CRF150f? Also what big bore would be the best for a CRF150f? I can feel the power of the bike, just wanna put a big bore on it... I was thinking a 197cc or 179cc would be good but I do not know! Here is my YouTube channel, I have 855 subscribers, I do Moto vlogs, come check it out. https://youtube.com/channel/UC_5qKxFyvoGkWB7oVTN_Xgw
  5. I have a 2005 husqvarna te 250 that has an Athena 300 big bore kit on. Anybody have any experience with jetting with these kits? It seems to be lean now and would like a good place to start getting it tuned.
  6. Hello! Got my wife's 07 CR85 here. It has a 105 Big Bore kit. The head gasket is leaking, both internally and externally. We bought the bike with the big bore kit already installed, so I don't know who provided the big bore kit and the previous owner was clueless to where he had it done - yes, a red flag that came up when we bought it, but hey, when the price is right...😉 Save for this issue, bike has been great, but anyway.... My question is, what is the best way to determine what replacement gasket to get? It is a gasket, not an oring, and I am not sure if it is a special size or not. I have thought about removing it and measuring it and calling Eric Gorr or one of the other engine guys out there but thought I would ask here first. Cheers!
  7. I've been on TT for a few years. I have an '01 400 EXC-R. She's been meticulously maintained and runs beautifully. I'm considering the 453cc with the 520 cam that I've read Travis and Dave and friends do. Most of the posts I read are old for the conversion. BTW, Travis, thanks for teaching me how to change the cam bearings, waterpump and adjust the valves. Couldn't have done it without you. Your videos are spot on.
