Did some work on my Lifan 150 this afternoon. Head swap to test my bottom end cam per per this thread http://www.miniriders.com.au/forum/tech-talk/17334-lifan-150-diffs-pics.html#post165157 and encountered something a bit weird. Bottom line is I am wondering if anyone else has found the oil...

Yeah I know the story. There are many funny postings on exactly this topic. But it's a fine balance - of course. Keep in mind that there's the frame, then the forks, which are joined by the clamps, and it's not always interchangeable in stages. If your missus does the books and/or checks...

No probs. The enjoyment gains from better suspension can be so huge. A common statement but so true. Good luck. Likewise, it's pretty funny to watch people try to ride fast on crappy handling pit bikes. Some are just so bad in terms of suspension and handling geometry. Keep in mind no...

The head on my 140 has an Akunar A1 bottom end 6.7mm lift cam. Akunar valves and springs too. It all did wonders to the performance. As did the carb setup and inlet port matching. I generally ride it pretty hard until I feel the both the engine and shock starting to fade due to heat build up...

The real solution depends on a few things. You'll have to work it out. Some clues ... Bottoming can be controlled by the compression dampening, the spring rate and the spring pre-load. Occasional bottoming is not such a bad thing. You should use all your suspension travel at some point on...

On the front just measure your own bike. No one can further help you there really. On the rear you'll find that most (if not all) swingarms made for a 12" rear wont fit a 14. Again you can measure your bike up yourself. Don't forget there is more to it than the extra 1" from the rim. The nobs...

The cooler has to be forward for the reason that I_Thump wrote. Plus the carb is where you are holding the cooler in the other position. If you are riding off road, you will need to extend your short front mud guard to keep the oil cooler clean and dent free. Be sure to dump the Lifan...

Sorry flarry, but that'd be a big call to trust those axle markers on a china bike. They will line up in most cases, but Mack's suggestion is the quickest and easiest way to be really sure. Buddy, with your chain slack, the problem is that the swing arm geometries differ a bit from bike to...

Highly possible that your CDI is faulty. Pretty common. Change that first and see how you go. Just get a stock Lifan replacement part, since they work fine.

Also, to go with your new engine, put some new oil in your forks, and give your shock to a suspension tuner and get them to put so good and heavy new shock oil in it. You'll probably be very happy with your bikes "new" legs. ;) In your forks, assuming they are a simple design, put some 10 or...

On my 140, it went from mild to wild (with big grins!) and all I did was: stage 1: alum oil slinger stage 2: OKO26 + inlet port matching + good air filter system. stage 3: head port tidy up (with sand paper) + akunar A1 cam + akunar valves + springs (must use their springs with 6.7mm lift cam)...

Damn, I had a good test ride today ... The right side clutch cover doesn't look so pretty any more. No crashing of significance, just the usual inside right boot rub. A polished alum cover would be more practical. No big deal. The Lifan 150 engine: I gave it a "hard" run in. About 15mins...

The SR has a "proper" frame. Twin main tubes. I'm onto the tyre situation. Pirelli MX scorp on the rear. Great in medium to hard. Not too bad in soft. On the front in the pics that's a Kenda milliville which is ok in soft/medium but not much good in anything else. Actually the Milliville is a...

Good work! I notice your cam lobes look very smooth in terms of their curves from initial valve open until close. And one cam has a "fatter" duration on its lobes than the other. Where do you get your cam shapes from? I mean do you come up with those yourself too?

Big 60mm two stage unifilter (100mm dia overall) mounted under the seat. No grit gets sucked into my engine. See this thread: http://www.miniriders.com.au/forum/tech-talk/15882-air-intake-snorkle-2.html#post153170

There is something worse than reviving an old thread on a message forum - and that's starting a new one with an old topic. ;) Old topics can always remain good topics and relevant to people [searching for info] for many years.

BTW, Mack, Can you please summarise in plain english what point Mr Myinnerrotorkits is trying to covey? He's obviously got something to say but english is understandably difficult for him. So I cannot tell if there's a message worth noting (for me as a consumer) or if he's just having a...

Seat has oil stains all over it. Ken and Linda said the Honda TRX125 (older quad) oil filter fits. I am sure it'll run just fine in stock form with my known setup OKO26. As mentioned the stock cam is much more on the money, and the lighter spinning mass is easily to feel with a little...

Yep that question has been answered 10 times over. It sounds like you have plenty of reading time. For the full run down, just search for all the posts by Cactus and Mack. There are round and oval bored carbs. 30mm is not 30mm. I had very good results with an OKO26 (round bore and flat...

Off topic but: If you have ADSL or cable internet, then for interstate or international calls just use VoIP! Eg. skype or one of Australia's many VoIP service providers (such as Oztell or Pennytel). 10c per call. Not timed. Been using it in our house for a few years now with an ATA to keep using...
